[show abstract][hide abstract] ABSTRACT: During 2008 to 2011, ear swabs and ectoparasites obtained by body searches and total body combs were collected from 252 cats (112 male, 140 female; 87 ≤9 months, 165 >9 months) from the greater Tirana area. Ear swabs were examined for the presence of ear mites, and skin scrapings were taken if clinical signs indicated the presence of other mite infections.
Overall, 59.1% of the cats tested positive for ectoparasites. Prevalence of ectoparasites was 52.0% for fleas (Ctenocephalides felis 51.2%, C. canis 2.0%, Leptopsylla segnis 0.4%), 8.3% for Otodectes cynotis, 8.3% for Felicola subrostratus, and 4.0% for Rhipicephalus sanguineus. No mites were found in skin scrapings.
There were no differences between sexes for the prevalence of any of the parasites recovered. Prevalence of infestation with ectoparasites did not differ between cats of different ages. However, comparing samples taken during different seasons, C. felis infestations were seen more frequently (p<0.0001) in autumn than in any other season. There also was a seasonal effect with R. sanguineus (p=0.0184): ticks were more frequently recorded in spring compared to summer and winter.
Mixed infections with up to three ectoparasite species were recorded in 22.8% of positive cats. Most common infestation combinations were C. felis + F. subrostratus (14 cats, 9.4%) and C. felis + O. cynotis (12 cats, 8.0%). This survey revealed a high prevalence of ecto-parasites in cats from suburban areas of Tirana. These data indicate that measures should be taken to reduce the infestation rate of these parasites, including raising awareness, employing effective treatment, and improving local animal care.

[show abstract][hide abstract] ABSTRACT: During 2012, ectoparasites obtained by body search, total body comb, and deep ear swabs were collected from 295 dogs (166 male, 129 female; approximately 2 months to 15 years old; 263 privately owned, 32 from shelter) originating from all regions of Bulgaria (Sofia Valley, Danube Plain, Upper Trakia Valley, Kazanlak Valley and Black Sea region). Privately owned dogs were used as guards, shepherds, or for hunting or breeding in kennels. Ear swabs were examined for the presence of ear mites, and skin scrapings were collected if clinical signs indicated the presence of other mite infestations.
Overall, 63.1% of the dogs tested positive for ectoparasites. Prevalence rates for ectoparasites were 48.1% for fleas (Ctenocephalides canis 44.1%, Pulex irritans 15.9%, C. felis 4.1%, Archaeopsylla erinacei 0.3%), 23.7% for ticks (Rhipicephalus sanguineus 19.7%, Ixodes ricinus 6.4%), and 0.3% for Cheyletiella spp.. No ear mites were found in any of the swab samples.
There was no difference between sexes for the prevalence of any of the parasites recovered. However, prevalence of infestation with P. irritans was significantly (p<0.0001) higher in shelter dogs than in privately owned dogs. In addition, the intensity of infestation of this species was higher in shelter dogs. In contrast, intensity of infestation of C. canis was higher (p=0.048) in privately owned dogs than in dogs from shelters.
Mixed infestations with up to four ectoparasite species were recorded in 34.9% of positive dogs. Most common combinations were C. canis + P. irritans (37 dogs, 19.9% of positive dogs) and C. canis + R. sanguineus (16 dogs, 8.6% of positive dogs). This survey revealed a generally high prevalence of ectoparasites in dogs in Bulgaria. The data indicate that measures should be taken to reduce the rate of infestation of these parasites, including raising awareness, employing effective treatment, and improving local animal care.

[show abstract][hide abstract] ABSTRACT: The efficacy of eprinomectin in an extended-release injection (ERI) formulation was evaluated in cattle harbouring induced infestations of Sarcoptes scabiei var. bovis (sarcoptic mange) in three studies conducted in Germany (two studies) and Austria (one study). A total of 44 cattle were included in the studies, 12 in one study and 16 in each of the other two studies. Approximately eight weeks following initial induced infestation, cattle in each study were formed into replicates of two animals each on the basis of pre-treatment bodyweights. Within replicates the animals were randomly allocated to one of two treatments: ERI vehicle (control) or Eprinomectin 5% (w/v) ERI (1.0mg eprinomectin/kg). Treatments were administered at 1mL/50kg bodyweight by subcutaneous injection in front of the shoulder once on day 0. The number of live mites in skin scrapings was determined prior to treatment and at weekly intervals for eight weeks after treatment. Severity of skin lesions was evaluated and scored when skin scrapings were taken. In all studies, animals were weighed before infestation and again prior to and at 56 days after treatment. Mite counts for treated cattle were significantly (p<0.05) lower than counts for controls from Day 7 onwards. Cattle treated with Eprinomectin ERI were Sarcoptes mite-free from seven, 21 or 28 days post-treatment to the end of the study in the three studies, and lesions regressed accordingly. Mean weight gain over the post-treatment period was significantly higher for treated cattle than for controls in two studies. All animals accepted the treatment well.
[show abstract][hide abstract] ABSTRACT: During 2011, faeces from 235 owned domestic cats from a rural area in western Hungary were examined using standard coproscopical techniques. The overall prevalence of cats with endoparasites was 39.6% (95% CI 33.3-46.1). The most frequently identified faecal forms were those of ascarids (Toxocara, 17.4%; Toxascaris 7.2%), followed by those of Aelurostrongylus lungworms (14.5%), hookworms (11.1%), taeniid cestodes (4.7%), Cystoisospora coccidians (4.3%), and capillarids (3.8%). Single and multiple infections with up to five parasites concurrently were founded in 24.7% and 14.9% of the cats, respectively. Mixed endoparasite infections were recorded more frequently (p=0.0245) in cats greater than one year old compared to younger cats. Young cats (≤1 year) were parasitized more frequently (p<0.05) with ascarids and Cystoisospora spp. but demonstrated infections of hookworms, lungworms and taeniid cestodes less often than the older cats. Cats with taeniid infection were more likely (p<0.05) to harbour Toxocara, hookworm, Aelurostrongylus, and capillarid infections than cats without taeniid cestodes. Cats of owners who claimed the use of wormers were less frequently helminth-positive compared to cats whose owners did not use anthelmintics (21.2% vs. 44.4%; p=0.001). A subset of 115 faecal samples screened by a coproantigen ELISA revealed Giardia-specific antigen in 37.4% samples. Giardia cysts were found by immunofluorescent staining in 30 of the 43 samples tested positive for Giardia by ELISA. In addition, ectoparasites collected from 82 cats by body search and combing were identified. Fleas (1-30 per cat), biting lice (Felicola subrostratus), and ticks (1-5 per cat) were isolated from 58, 1 and 43 cats, respectively. Ctenocephalides felis was identified on all flea infested cats while single specimens of C. canis and Pulex irritans were recovered from three and two cats, respectively. All but one tick collected were adult Ixodes ricinus; the single other tick was a nymph of I. canisuga. By providing basic data on the epidemiology of parasitic infections, the results of this survey should emphasize the need of attending to parasites of cats from the veterinary point of view with respect to both appropriate diagnostics and control.
[show abstract][hide abstract] ABSTRACT: Prevalence and intensity of gastrointestinal parasites were studied through a longitudinal survey in 400 horses over a 17-month period in an abattoir in Germany. Three hundred and ten horses (77.5 %) were demonstrated harbouring endoparasites either by direct recovery of parasites from the digestive tract and/or in terms of faecal egg counts (strongyles). The following parasites were found (percentage prevalence, range of counts): Gasterophilus intestinalis larvae (2.25 %, 1-154), Gasterophilus nasalis larvae (0.25 %, 44), Trichostrongylus axei (11.0 %, 1-3,620), Habronema majus (8.0 %; 1-422), Habronema muscae (26.5 %, 1-3,563), Habronema spp. fourth-stage larvae (5.5 %; 1-1,365), Parascaris equorum (total prevalence 11.3 %; adults 8.8 %, 1-178; fourth-stage larvae 2.5 %, 5-2,320), Anoplocephala perfoliata (28.5 %, 1-2,013) and Paranoplocephala mamillana (1.0 %, 1-11). Strongyle eggs (≥10 eggs per gram of faeces) were recorded in 60.8 % of the horses (10-6,450 eggs per gram of faeces).Prevalences of infection with T. axei, P. equorum and strongyles did not show a correlation to specific seasons. In contrast, a significant variation among seasons of collection was shown for the infection rates of Habronema spp. (p < 0.05) and A. perfoliata (p < 0.001). Seasonal prevalence of Habronema spp. infection was significantly (p < 0.01) higher in summer (39.0 %), autumn (34.8 %) and winter (36.5 %) than in spring (18.7 %), and A. perfoliata were significantly (p < 0.001) more often recorded during autumn (36.1 %) and winter (36.5 %) than in spring (17.3 %) and summer (15.9 %). Prevalences of T. axei, Habronema spp., strongyles and A. perfoliata in male and female horses were almost alike, but ascarids were significantly (p = 0.025) more often recorded in male than in female horses.

[show abstract][hide abstract] ABSTRACT: From 2008 to 2010, internal organs of 78 cats (36 male, 42 female; 28 ≤9 months; 50 >9 months) from suburban areas around Tirana were examined for parasites. For examination were available: 75 gastrointestinal tracts, 67 livers, 73 lungs and 57 urinary bladders.
All but one cat were demonstrated to harbour parasites.
Overall, 97% of the cats had gastrointestinal helminths, and 87% were infected with two or more helminth species in the gut. The most prevalent species was Toxocara cati (prevalence, 80%; range, 1-78) followed by Ancylostoma tubaeforme (56%; 1-97). Dipylidium caninum (53%; 1-181) and Joyeuxiella pasqualei (43%; 1-95) were the most often recovered cestodes while Diplopylidium spp. cestodes were found in 9% (range, 1-23) of the intestines. In total 80% of the cats carried concomitant nematode and cestode infections. In addition, one acanthocephalan (Sphaerirostris picae) was isolated from the intestine of one cat.
Examination of the livers revealed trematodes, Pseudamphistomum truncatum, in one cat. Two nematode species, Aelurostrongylus abstrusus (78%; 1-64) and Capillaria aerophila (47%; 1-45) were recorded in the lungs with 44% of the lungs harbouring both species. Additionally, one Linguatula serrata larva was isolated from one lung.
Capillaria plica (range, 1-71) were recovered from 67% of the urinary bladders.
Adult cats (>9 months) were more frequently parasitized with J. pasqualei (p=0.028) and C. plica (p=0.016). Young (9 months) T. cati-positive cats harboured significantly (p<0.01) more ascarids than the older T. cati-positive cats.

[show abstract][hide abstract] ABSTRACT: A study was conducted to confirm the efficacy of topical eprinomectin against nematodes and to evaluate the pharmacokinetics in cattle prevented from having physical contact with other cattle and from self-grooming. Sixteen male Brown Swiss calves were infected with larvae of recently isolated nematode parasites. Inoculation was scheduled so that the nematodes were expected to be adults at the time of treatment. Animals were blocked based on pretreatment body weight and randomly allocated to the untreated control group or the group treated with EPRINEX® Pour-On (Merial; 0.5 mg eprinomectin per kilogram body weight). Plasma samples were collected prior to and between 1 and 21 days following treatment and analysed for eprinomectin (B1a component) concentrations. For parasite recovery, identification and counting, animals were humanely euthanized 21 days after treatment. Calves treated with eprinomectin had significantly (p < 0.05) fewer (>99 % reduction) adult Dictyocaulus viviparus, Bunostomum phlebotomum, Cooperia oncophora, Cooperia surnabada, Cooperia punctata, Nematodirus helvetianus, Oesophagostomum radiatum, Ostertagia ostertagi, Ostertagia lyrata, and Trichostrongylus axei and inhibited fourth-stage Nematodirus and Ostertagia larvae than the controls. The main pharmacokinetic parameters of eprinomectin B1a were: AUC(inf), 124 ± 24 day ng/mL; T (1/2), 5.2 ± 0.9 days; and C (max), 9.7 ± 2.2 ng/mL. Individual maximal concentrations were observed 3-7 days after treatment. This study confirmed the continued high level of efficacy of topically administered eprinomectin against a wide range of recently isolated nematodes. In addition, this study demonstrates that oral ingestion is not required to achieve adequate exposure for efficacy following topical administration of eprinomectin.

[show abstract][hide abstract] ABSTRACT: Untersucht wurde die Endoparasitenfauna von 108 Stücken Sikawild (42 Kälber, 20 etwa einjährige Stücke, 46 über ein Jahr alte
Stücke), die in den Jagdjahren 2003 bis 2005 in den beiden Sika-Vorkommen in Österreich (Ostrong, 35 Stücke; Tullner Donauauen,
73 Stücke) erlegt worden sind. Nachgewiesen wurden Vertreter von mindestens 4 Protozoenspezies (Eimeria austriaca, Eimeria robusta, Eimeria sordida, Sarcocystis spp.), jeweils zwei Arten von Zestoden (Moniezia benedeni, Taenia hydatigena-Zystizerkus) und Trematoden (Fasciola hepatica, Dicrocoelium chinensis?) sowie 16 Nematodenarten: 14 Arten im Magen-Darm-Kanal und jeweils eine Art in der Lunge (Dictyocaulus eckerti) bzw. auf den serösen Häuten der Bauchhöhlenorgane (Setaria cervi). Ein Befall mit Endoparasiten war bei allen 108 Stücken nachweisbar: bei 44% der Stücke wurden Sarkosporidien-Zysten nachgewiesen,
bei 14,8% Eimeria spp., bei 4,6% Fasciola hepatica, bei 27,6% Dicrocoelium chinensis?, bei 3,1% Dictyocaulus eckerti, bei 3,7% Moniezia benedeni und bei 98,1% Magen-Darm-Nematoden. Die Befallsstärke mit Magen-Darm-Nematoden variierte zwischen 0 und 1089 bei einem (geometrischen)
Mittelwert von 149 Würmern. Der Lagmagen war der am stärksten parasitierte Abschnitt des Verdauungskanals und beherbergte
81% der gesamten Nematodenbürde, gefolgt von Dünndarm und Dickdarm mit Anteilen von 14% bzw. 5%. Die am häufigsten gefundenen
Nematoden-Spezies waren Spiculopteragia houdemeri (93,5%), Oesophagostomum sikae (87,9%), Oesophagostomum venulosum (51,4%), Cooperia pectinata (42,1%), Spiculopteragia böhmi (23,4%) und Ostertagia leptospicularis (16,8%). Spiculopteragia houdemeri und Rinadia andreevae wurden erstmals als Parasiten in Österreich nachgewiesen.
The endoparasite fauna of 108 sika deer (42 calves <1 year, 20 approximately 1 year old animals, 46 animals >1 year) originating
from the two free-living sika deer populations in Austria (Ostrong, 35 animals; Tullner Donauauen, 73 animals) was studied.
The deer were shot during the hunting seasons 2003–2005. In all, at least four species of protozoa (Eimeria austriaca, Eimeria robusta, Eimeria sordida; Sarcocystis spp.), two species each of cestodes (Moniezia benedeni, larval cyst of Taenia hydatigena) and trematodes (Dicrocoelium chinensis?, Fasciola hepatica) and 16 species of nematodes were identified including 14 species recovered from the gastro-intestinal tracts and one species
each isolated from the lungs (Dictyocaulus eckerti) and the abdominal cavity (Setaria cervi). Endoparasites were recovered from all 108 deer with prevalences of 44% for Sarcocystis spp., 14.8% for Eimeria spp., 4.6% for Fasciola hepatica, 27.6% for Dicrocoelium chinensis?, 3.1% for Dictyocaulus eckerti, 3.7% for Moniezia benedeni and 98.1% for gastro-intestinal nematodes. The burden of gastro-intestinal nematodes ranged from zero to 1089 with a geometric
mean of 149 worms. The abomasums, small and large intestines harboured 81%, 14% and 5% of the total gastro-intestinal nematode
burden. Spiculopteragia houdemeri (93.5%), Oesophagostomum sikae (87.9%), Oesophagostomum venulosum (51.4%), Cooperia pectinata (42.1%), Spiculopteragia böhmi (23.4%) and Ostertagia leptospicularis (16.8%) were the most prevalent nematode species of the gastro-intestinal tracts. Spiculopteragia houdemeri and Rinadia andreevae were new records for Austria.

[show abstract][hide abstract] ABSTRACT: A massive infestation with Lynxacarus mustelae (Megnin, 1885) (Acari, Astigmata, Listrophoridae) was diagnosed in a stone marten (Martes foina) from Tyrol, Austria. In addition, Ixodes rugicollis and Trichodectes retusus are reported for the first time in Austria, and the five species of helminths found (Capillaria aerophila, C. mustelorum, C. paranalis, C. plica, Molineus patens) are first records in the stone marten in the country.
[show abstract][hide abstract] ABSTRACT: Following the recovery of first-stage nematode larvae indicative of Aelurostrongylus abstrusus infection in the faeces of free-roaming cats from the greater Tirana area, examination of 18 cats at necropsy revealed nine of them harbouring adult A. abstrusus (Railliet, 1898) in the lungs (prevalence, 50%; range, 1-11). In addition to A. abstrusus, Eucoleus aerophilus (16.7%; 1-9) was isolated from the lungs, and Toxocara cati (83.3%; 2-33), Ancylostoma tubaeforme (44.4%; 1-20), Dipylidium caninum (83.3%; 1-164), Joyeuxiella pasqualei (11.1%; 1-3) and one specimen of an acanthocephalan (5.5%) were recovered from the gastrointestinal tract. Furthermore, oocysts of Cystoisospora felis and C. rivolta were found in the rectal faeces of 5.6% and 11.1% of the cats, respectively. In conclusion, the prevalence of endoparasite infection in free-roaming cats in Tirana can be considered to be high. The occurrence of A. abstrusus, which may cause respiratory distress in cats, is reported for the first time in Albania.
[show abstract][hide abstract] ABSTRACT: Faecal samples of 250 horses from farms with a known history of tapeworm infection were examined comparatively for cestode eggs using a double centrifugation/combined sedimentation-floatation technique. From each faecal sample, three 5 g and three 15 g subsamples were processed, each using either saturated NaCl solution, specific gravity (sp. g.) 1.2 [NaCl]; concentrated sugar solution, sp. g. 1.26 [sugar]; or concentrated ZnSO4 solution, sp. g. 1.3 [ZnSO4] for floatation. In total, faeces from 187 horses ( = 74.8%) tested 'positive' for Anoplocephala eggs. Percentages of samples testing 'positive' for Anoplocephala ova were: 57.2% for 5 g faeces/NaCl, 66% for 15 g faeces/NaCl, 66% for 5 g faeces/sugar, 72.8% for 15 g faeces/sugar, 55.6% for 5 g faeces/ZnSO4, and 61.2% for 15 g faeces/ZnSO4, respectively. Processing of 15 g faecal samples resulted in a significant (P < 0.05; McNemar's χ2-test) increase in the percentage of Anoplocephala egg detection compared to processing of 5 g samples for all floatation solutions. By processing 15 g faecal samples using sugar solution for floatation, 97.3% of all samples that tested 'positive' for Anoplocephala eggs were identified; there was no significant difference between the rate of samples that tested 'positive' using 15 g faeces/sugar (72.8%) and the total rate of samples that tested 'positive' (74.8%). Conversely, percentages of 'positive' samples from other test combinations were significantly (P < 0.0001, McNemar's χ2-test) lower than the total rate of samples testing 'positive'. Processing faecal samples using sugar solution for floatation gave significantly (P < 0.05, Wilcoxon test) higher Anoplocephala egg counts than using NaCl and ZnSO4 solutions, for both 5 g and 15 g faecal samples. The double centrifugation technique using 15 g faecal samples and concentrated sugar solution for floatation appeared to offer an advantage for the detection of Anoplocephala eggs in horse faeces compared to the other test combinations.

[show abstract][hide abstract] ABSTRACT: From 2004 to 2009, the digestive tracts of 111 dogs from suburban areas around Tirana, Albania, were examined for intestinal helminths. In addition, rectal faecal samples of all dogs were examined for protozoan infections and 48 faecal samples from dogs >6 months of age were processed with the Baermann technique to test for the excretion of lungworm larvae. The heart and pulmonary arteries of 30 dogs >6 months of age also were examined for nematode parasites. The intestinal parasite fauna of the dogs included three protozoan species (Cystoisospora canis, Cystoisospora ohioensis/burrowsi, Sarcocystis spp.), three cestode species (Dipylidium caninum, Taenia hydatigena, Echinococcus granulosus), five nematode species (Ancylostoma caninum, Uncinaria stenocephala, Toxocara canis, Toxascaris leonina, Trichuris vulpis) and one acanthocephalan (Centrorhynchus buteonis). Rates of infection were: 15.3% for C. canis, 31.5% for C. ohioensis/burrowsi, 1.8% for Sarcocystis spp., 65.8% for D. caninum, 16.2% for T. hydatigena, 2.7% for E. granulosus (genotype G1), 13.5% for A. caninum, 64.9% for U. stenocephala, 75.7% for T. canis, 0.9% for T. leonina, 21.6% for T. vulpis and 0.9% for C. buteonis. Up to six species of gastrointestinal parasites were found per dog. The 63 ≤ 6-month-old dogs harboured significantly (p<0.001) fewer gastrointestinal parasite species concurrently (mean 2.65 ± 1.25 species per animal) than the 48 older animals (mean 3.77 ± 1.45 species per animal). Dogs >6 months of age harboured significantly (p<0.05) more D. caninum, T. hydatigena, A. caninum, U. stenocephala and T. vulpis compared to younger dogs. Conversely, the younger dogs harboured significantly (p<0.001) more T. canis than the older ones. There was no difference in the male and female dogs' counts of individual intestinal helminth species apart from T. hydatigena in dogs >6 months of age: Male dogs harboured significantly (p<0.05) more tapeworms than female dogs. Based on faecal examination, there was no indication for lungworm infection; however, two adult heartworms (Dirofilaria immitis) were found in the right ventricle of one dog.

[show abstract][hide abstract] ABSTRACT: The importance of arthropod-borne diseases increased in the recent past in particular due to frequent travel with dogs in or by importing of dogs from regions with endemic occurrence of these diseases. While the epidemiological situation is well known for the western parts of the Mediterranean, only limited data is available for Eastern Europe and the Balkans. Thirty clinically healthy dogs from suburban areas of Tirana, Albania, were tested for Babesia canis, Hepatozoon spp., Leishmania spp., Dirofilaria spp., Ehrlichia canis, Anaplasma phagocytophilum, Bartonella spp. and Rickettsia spp. using direct and indirect methods. Antibodies against and/or pathogens of arthropod-borne diseases were detected in the blood of 20 (67%) dogs. Nineteen dogs (63%) had antibodies against B. canis, E. canis and/or A. phagocytophilum. Babesia c. canis, Babesia c. vogeli, Hepatozoon spp., D. immitis and/or E. canis were identified by blood smear, PCR or ELISA in 13 (43%) dogs. There was no evidence for Leishmania spp., Bartonella spp. and Rickettsia spp. infections.
[show abstract][hide abstract] ABSTRACT: One hundred eighty-one dogs and 26 short-hair cats from suburban areas around Tirana, Albania were examined for ectoparasite infestation. The dogs were examined on several occasions from 2005 through 2009 representing three seasons: winter (December-February), spring (March-May), and summer (June-August); the cats were examined in late autumn (November). In addition, deep ear swab specimens of 30 dogs were examined for ear mites. The arthropod ectoparasite fauna of the dogs included two tick species (Rhipicephalus sanguineus and Ixodes ricinus), three mite species (Sarcoptes scabiei var. canis, Otodectes cynotis, and Demodex canis), three flea species (Ctenocephalides canis, Ctenocephalides felis, and Pulex irritans), and one louse species (Trichodectes canis). In the dogs, rates of infestation were 23.8% for R. sanguineus, 0.6% for I. ricinus, 4.4% for S. scabiei var. canis, 6.7% for O. cynotis, 0.6% for D. canis, 75.7% for C. canis, 5.0% for C. felis, 8.3% for P. irritans, and 6.6% for T. canis. Mixed infestation with two or three species of ectoparasites was recorded on 38.1% of the dogs. Fleas infested 75.7% dogs (geometric mean, 3.96; range, 1-80) and were observed in winter, spring, and summer with increasing prevalences of 64.3%, 75.9%, and 100%. Ticks parasitized 24.3% of the dogs (geometric mean, 0.41; range, 1-331). R. sanguineus ticks were recorded on 34.2% and 50% of the dogs examined in spring and summer, respectively, but were absent on the dogs during winter except for a single I. ricinus specimen observed. Prevalence of infestation with R. sanguineus, S. scabiei var. canis, C. felis, P. irritans, and T. canis did not differ between dogs < or = 6 months and dogs > 6 months of age; however, prevalence of infestation with C. canis was significantly (p < 0.01) higher in dogs > 6 months old. There was no difference between the sexes for the prevalences of infestation with those parasites. The examination of the cats revealed infestation with only one species of ectoparasite, C. felis (prevalence, 100%; geometric mean, 2.5; range, 1-9).

The deer were shot during the hunting seasons 2003-2005. In all, at least four species of protozoa (Eimeria austriaca, Eimeria robusta, Eimeria sordida; Sarcocystis spp.), two species each of cestodes (Moniezia benedeni, larval cyst of Taenia hydatigena) and trematodes (Dicrocoelium chinensis?, Fasciola hepatica) and 16 species of nematodes were identified including 14 species recovered from the gastro-intestinal tracts and one species each isolated from the lungs (Dictyocaulus eckerti) and the abdominal cavity (Setaria cervi). Endoparasites were recovered from all 108 deer with prevalences of 44% for Sarcocystis spp., 14.8% for Eimeria spp., 4.6% for Fasciola hepatica, 27.6% for Dicrocoelium chinensis?, 3.1% for Dictyocaulus eckerti, 3.7% for Moniezia benedeni and 98.1% for gastro-intestinal nematodes. The burden of gastro-intestinal nematodes ranged from zero to 1089 with a geometric mean of 149 worms. The abomasums, small and large intestines harboured 81%, 14% and 5% of the total gastro-intestinal nematode burden. Spiculopteragia houdemeri (93.5%), Oesophagostomum sikae (87.9%), Oesophagostomum venulosum (51.4%), Cooperia pectinata (42.1%), Spiculopteragia böhmi (23.4%) and Ostertagia leptospicularis (16.8%) were the most prevalent nematode species of the gastro-intestinal tracts. Spiculopteragia houdemeri and Rinadia andreevae were new records for Austria.
[show abstract][hide abstract] ABSTRACT: A randomized block design study was conducted to confirm the efficacy of topical eprinomectin against naturally acquired Chorioptes bovis mite infestations. Twelve adult Simmentaler Fleckvieh cattle were formed into six replicates of two animals based on pretreatment mite counts. Within replicates, animals were randomly allocated to untreated controls or were treated with eprinomectin 0.5% pour-on solution at 1 mL/10 kg body weight (0.5 mg eprinomectin/kg body weight). Live mites were counted, and mange lesions were scored prior to treatment and at weekly intervals until the end of the study on day 56. Feed consumption was recorded daily throughout the study, and body weights were measured. Differences between variables were declared significant if p < or = 0.05. Mite counts for the cattle treated with eprinomectin were reduced by 100% from day 14 through the end of the study (p < 0.05). At each examination from day 21 through the end of the study, treated animals were significantly clinically improved as measured by lesion scoring compared with untreated controls. Weight gain and feed conversion efficiency were numerically higher in the eprinomectin-treated group. Results of this study demonstrate a positive response in growth rate following effective treatment of cattle for chorioptic mange and underline the economic importance of the parasite and the value of treatment.
