    ABSTRACT: A 3-month-old female trotter foal was euthanized due to severe dyspnoea. Pathomorphologically a chronic granulomatous to necrotizing pneumonia was found and Rhodoccocus (R.) equi was isolated microbiologically. An immunohistological method using a murine monoclonal antibody against a 15-17 kDa antigen of virulent R. equi was established in formalin-fixed and paraffin-embedded tissue sections using various antigen retrieval techniques to optimize the staining results. Microwave treatment was most suitable for the demonstration of bacterial antigen localized predominantly in intralesional macrophages. Immunohistology is an additional method for identifying R. equi-infections in equine tissue and may be useful in retrospective studies on paraffin-embedded archive material.

    ABSTRACT: The study was aimed at determining the cause of a disease in a horse exhibiting symptoms of fever, joint effusion, weakness, and extravasations on the mucous membranes. Blood was drawn from the animal for haematological and biochemical molecular tests. The PCR technique revealed the presence of 16S RNA Ehrlichia spp. genetic material in the blood samples. DNA amplification by means of primers EHR 521 and EHR 747 gave a product with a volume of 247 bp.The sequence of the PCR product obtained showed a 97.6% similarity with a sequence of a fragment of 16S RNA Ehrlichia phagocytophila, gene number EU 090186 in the GenBank. A microscopic examination of blood smears demonstrated the presence in the neutrophiles of intracytoplasmatic structures characteristic for Ehrlichia.The treatment involved the intravenous application of oxytetracycline at a dose of 8 mg/kg of body mass for 7 days, and resulted in a gradual recovery. The positive results of the molecular test and the positive reaction to the therapy are an indication of the first case of ehrlichiosis in a horse in Poland as confirmed in laboratory test.

    ABSTRACT: This report deals with an enzootic due to Salmonella Typhimurium in two free living Eurasian siskins (Spinus spinus Linnaeus, 1758). Other birds in the vicinity of the siskins were not affected. Clinical signs consisted of non-specific symptoms such as ruffled plumage, apathy and reduced food intake. During necropsy, gross lesions were enlarged livers with focal necrosis, pale spleens, enlarged kidneys, pneumonia and enteritis. Salmonella Typhimurium was isolated from internal organs in pure culture. Using the polymerase chain reaction, the detection of Salmonella according to EN ISO 6579:2002 was confirmed. The detailed characterisation of both isolates in the Federal Institute for Risk Assessment and in the Robert Koch Institute yielded for the first siskin Salmonella Typhimurium, 4, 5, 12: i : 1, 2, LT DT104, BT a and for the second siskin Salmonella Typhimurium, 4,12 i : 1, 2, LT DT013, BT c. These phage types were identified for the first time in siskins. The detected phage types have importance as causes of disease not only for free living siskins but also as infectious and zoonotic agents for domestic poultry and poultry products.

    ABSTRACT: A multicentre field study was conducted in accordance with VICH Guideline on Good Clinical Practice (VICH 2000) to confirm the efficacy and safety of a new formulation of cefquinome for the treatment of naturally occurring severe bacterial infections and septicaemia in foals. Thirty-nine foals suffering from severe bacterial infections (such as pneumonia, gastro-enteritis, arthritis, omphalitis, or wound infections) or acute septicaemia were treated twice daily with the test product (1 mg cefquinome/kg body weight) intravenously for three days and then intramuscularly for three to 11 days. Investigators examined the foals daily and scored both systemic and local clinical signs to assess the response to treatment, treatment success and relapses. On the day of inclusion a blood sample was taken from each foal for IgG determination and blood culture. In case of abnormal clinical findings additional samples were taken for bacteriology. Treatment was successful in 87.2% of cases (34 of 39 foals) and no relapses were observed. The average duration of treatment was 7.5 days. At inclusion, bacterial culture was positive in 40.5% (15 out of 37) of the blood cultures. Escherichia coli, Clostridium perfringens and Staphylococcus spp. were the most common isolates and were all susceptible to cefquinome. E. coli predominated in swabs from umbilical and open wound infections, and in rectal swabs E. coli. There was no correlation between IgG at inclusion and study outcome or treatment duration. The test product was very well tolerated by all of the foals following intravenous and intramuscular injection. The cefquinome formulation tested was effective and safe in the treatment of severe bacterial infections and septicaemia in foals under field conditions.

    ABSTRACT: The objective of the present study was to investigate the role of heat shock proteins (Hsps) as potential stress response marker in several organs of transported pigs. Constitutive (Hsp90, Hsp70 and Hsp27) and inducible (Hsp72 and Hsp86) Hsps expressed in skeletal muscle, heart, liver and kidney of transported young pigs were investigated. The study comprised 13 German Landrace line pigs (mean weight, approx. 35 +/- 1 kg). Eight animals (n = 8) were transported for a period of 6 h, whereas the control group (n = 5) was kept under normal housing conditions. Identification of Hsps was performed by immunoblot using porcine specific antibodies. Although the 5 Hsps were regularly detected in all porcine tissues, no clear up-regulation could be observed due to transportation. Densitometrical analysis of the immunoblots revealed an unexpected result. Every tissue had a significant reduction of at least 2 Hsp members: Kidney (Hsp90 and Hsp70), M. longissimus dorsi (Hsp90 and Hsp72) and M. gluteus maximus superficialis (Hsp90 and Hsp86), liver (Hsp90, Hsp86 and Hsp27). The heart was most affected, all Hsps were significantly reduced by 26% to 41% after 6 h of transportation. The regular reduction of the large Hsp90 and Hsp86 in nearly all tissues examined point to a new and critical role these Hsps might have in counteracting short-term stress reactions. The fast reduction of Hsps in fatal organs such as heart and kidney may have a relation to organ failure. Hsp90 level may therefore serve as a potential marker for the stress pigs are suffering during transportation.

    ABSTRACT: For a long time MRSA were associated only with human medicine, although with Summary increased incidence in human medicine, MRSA was almost simultaneously reported to occur in veterinary medicine as well. Following initial intermittent reports of appearances of MRSA in cattle and milkers, clusters of nosocomial infections in various animal species in several European as well as one Canadian animal hospital stated. During 2003-2007 the cluster of MRSA ST 254, t036 and MRSA ST 398, t011/t034 were isolated from wound infections in hospitalised horses as well as from nasal swabs from horses and from veterinary staff in a horse clinic at the veterinary university Vienna (VUW). MRSA ST 1, t127 were for first time detected in infect localisations solely in three horses. Considered epidemiologically, MRSA ST 254, t009 is known as "Hannover-epidemic strain" from health care settings. However, with the spa-type and the SCCmec-element IVc it exhibits two major differences and is therefore definitely distinct from the MRSA ST 254 found in horses and veterinary employees from UVW. With respect to evolution both lineages evolved independently from on another but can be ascribed to a common ancestor within the clonal complex CC8. MRSA ST 398, in 2003 observed for the first time as MSSA in pigs in France, was first detected in horses in 2006 following augmented confirmations at the VUW in 2007. Although the primary reservoir of MRSA ST398 is obviously in pigs as also recorded in Germany, it is obviously to colonize and to cause infections in other host species such as humans, cattle, dogs, cats and poultry. Infections in hospitals in individuals even without contact to animals and two cases with death in exceptional severe situation point at the pronounced patho-potency. Its flexibility concerning host adaptation and acquisition of additional virulence genes gets the claim for the obligation to report MRSA cases. The proportion of MRSA ST398 among infections in humans is infrequent so far, mainly patients with direct or familial contacts to livestock are affected. There were, however, also a few cases of invasive nosocomial infections in patients without any association to animal husbandry. This underlines the necessity for further surveillance of the evolution of MRSA ST398 and its dissemination.

    ABSTRACT: Campylobacter coli is an etiological agent of gastrointestinal and extraintestinal infections in man and animals, and can be found as a commensal in gastrointestinal tract of animals. In this study, we aimed to determine differences among C coli strains in colonization of the intestinal tract of mice. Seven C coli strains isolated from diarrheic patients, asymptomatic hosts and chicken carcasses were used for this study. Each strain was inoculated with 0.1 ml of a bacterial suspension (3 x 10(8) CFU/ml) to 5 weanling mice, intragastrically. For the isolation of C coli, faecal pellets collected before inoculation and after inoculation at particular intervals were cultured on Campylobacter Selective Agar. Seven C. coli strains were divided into 3 colonization groups, based on faecal shedding. Group I showed immediate colonization, with prolonged excretion of organism in all mice. Group II showed delayed and short time colonization of C. coli. Group III could not colonize mice. Division of isolates into colonization groups was as follows: Group I included 3 strains from gastrointestinal disease; Group II included 2 strains from asymptomatic hosts and Group III included 2 strains from chicken carcasses. The study showed that there were marked differences among C coli strains with respect to their colonization potential and it may depend upon the origin of the strain. For understanding the complete pathogenesis of Campylobacter spp., a greater number of strains from different sources and geographical locations require to be tested in further investigations in the light of our findings.

    ABSTRACT: The present study was undertaken to investigate the effects of type of ram presence (permanent vs. intermittent) on estrus onset, estrus duration and frequency of sexual behaviours in Kivircik ewes. During the breeding season, 20 multiparous Kivircik ewes were divided into two groups of permanent (PR) and intermittent (IR) presence of ram. Estrus was synchronized with fluorgestone acetate intravaginal sponges left for 14 days, plus an injection of 600 IU PMSG at the time of sponge removal. PR ewes introduced with ram immediately after sponge removal and remained with the ram throughout the study (5 days). IR ewes were exposed to ram twice a day, only during the observation periods. Behavioural observations were performed twice a day (at 07:00 a. m. and 07:00 p.m.) for a 2-hour period. Estrus onset was 32.40 +/- 1.60 h for PR group and 27.60 +/- 2.40 h for IR group (p > 0.05). Estrus duration was 15.60 +/- 1.83 h and 34.80 +/- 2.15 h for the same groups, respectively (p < 0.001). Standing was the most frequently displayed behaviour in both groups. IR ewes displayed sexual (p < 0.001), eating (p < 0.001), standing (p < 0.001), walking (p < 0.001), urination (p < 0.001) and defecation (p < 0.05) behaviours much more than the PR ewes. Frequency of each sexual behaviour was higher in IR group compared with PR group throughout the study. Among the proceptive behaviours investigated, head-turning was the most frequently displayed behaviour in both groups. Soliciting, non-firm standing, sniffing scrotum and anogenital sniffing behaviours were also expressed by the ewes considerably. It is concluded that, if the ewes are exposed to ram intermittently, behavioural signs of estrus could be recognized more successfully. Furthermore, the possibility of insemination of estrous ewes becomes much higher by the intermittent presence of ram and thus reproductive performance of the herd could be improved.

    ABSTRACT: A 13-year-old Standardbred gelding was referred for evaluation of continuous abdominal pain. Rectal examination revealed a dislocated large colon (Dislocatio coli ad dextram). The horse showed muscle fasciculations and appeared lethargic. It was sent to surgery because of persistent colic. In transit the gelding showed an unstable walk and immediately prior to surgery a wide-based stance in the hindlimbs. Laparotomy revealed a retroflexion of the large colon and a secundary mesenterial volvulus. After surgery the horse remained recumbent. Due to the comatose state and poor prognosis the gelding was euthanized after 15 hours of recumbency. Necropsy indicated hyperaemic meninges, edema of gliacells and submeningeal tissue with vacuolization and loss of several cerebellar Purkinjecells as well as multiple conglomerates of Alzheimer type II astrocyte groups within the grey matter. Further findings included marked hepatolipidosis, multiple gastric ulcers, small intestinal hyperaemia with mild mononuclear inflammation, tapeworm-infestation of the caecum and moderate chronic enteritis with eosinophilic component in the large intestine. To the best of our knowledge, this was the first case of a horse with colic and concurrent encephalopathy without primary liver disease described in a German-speaking country.

    ABSTRACT: The present study intended to investigate the compatibility of the orally applicated Salmonella Typhimurium live vaccine Salmoporc on day 3 and 21, respectively. Piglets which only received saline solution orally were used as negative control. During eight hours following vaccination, fecal consistency, body temperature as well as body condition were evaluated. Furthermore, in addition to the daily measures of body temperature and body condition, weekly weight controls as well as bacteriological examination referring to the duration of excretion of the vaccine strain, were carried out until the end of the study. Additionally, distribution and persistence of the pathogen in different tissues were examined. Using serological determination of salmonella antibodies, immune response was scrutinised. Oral vaccination resulted in a significant rise of the body temperature.The vaccine strain could be isolated from fecal samples until the 28th day (seven days after the second vaccination). The vaccination strain persisted until six weeks after the second vaccination in organs of the piglets, whereas the last detection was from samples of small and large intestine. Field strains could neither be isolated from fecal nor from organ samples of vaccinated and control group. Until the end of the study, control animals were negative by bacteriological examination of fecal and organic samples. Seroconversion was observed from day seven after the second vaccination. Mean concentration of antibodies was significantly higher in vaccinated than in control animals three weeks after vaccination.

    ABSTRACT: By treatment of single animals or a live stock a treatment regimen has to be chosen, which guarantees a sufficient concentration of the administered drug in the target tissue. On the other hand, particular care has to be taken to avoid that single animals get a too high, intolerable dose of the administered drug. These elementary requirements must be met by the attending veterinarian.The treatment schedule must be in line with the current phamaceutical law. Some of the most outstanding problems associated with application via feed and water are discussed. Crucial factors apart from practicability are the bioavailability depending on pharmaceutical form and the avoidance of displacements of drugs. Future efforts should focus on the optimization of oral medication.

    ABSTRACT: Histomoniasis was detected and described in naturally affected 35 turkeys. A polymerase chain reaction, which amplified a 209 bp region from the small subunit ribosomal RNA gene of H. meleagridis, was used and compared to the detection by histopathological observation of the histomonad trophozoits. In gross examination, typical histomoniasis lesions of hyperaemia and thickening of the cecal wall with grayish-yellow cecal cores were seen. In livers and kidneys, variably sized multiple foci of circumscribed necrotic areas were observed. Microscopically, varying amounts of histomonad trophozoits were detected in cecum (100%), liver (91.4%), kidney (17.1%), spleen (11.4%), proventriculus (5.7%) and bursa of Fabricius (2.8%). Mononuclear cell infiltration often containing giant cells in ceca, livers, kidneys and a proventriculus was observed. Lymphoid depletion was present in spleen and bursa of Fabricius. PCR assay detected the agent in cecum (100%), liver (100%), kidney (31.4%), spleen (25.7%), proventriculus (11.4%), bursa of Fabricius (11.4%) and lung (17.1%). This study describes histomoniasis lesions especially in several unusual locations such as kidney, spleen, bursa of Fabricius and proventriculus and could provide a help in the diagnosis of the natural histomoniasis in turkeys. It was also shown that PCR based detection was a more sensitive technique than detection based on histopathological observation.

    ABSTRACT: A black and white female German Holstein calf showed a highly deformed cranium. The animal was not able to stand. Further findings were bilateral strabismus divergens and negative pupillary light reflexes. Magnetic resonance imaging and pathological-anatomical examination showed that the cerebrum was replaced to a high degree by the ventricle system filled with 1.5 liters of cerebrospinal fluid. The hemispheres of the cerebellum were ruptured by the dilated fourth ventricle. In addition, the vermis and pons were missing and fluid accumulation in the subarachnoidal space extending up to the first spinal cord segments was visible. Inbreeding was not detected in the 3-generation-pedigree. No other affected calves from the same parents were known at the farm. Chromosomal abnormalities could not be detected after examination of 30 metaphase spreads using a light microscope. Infections and parasitic diseases could be ruled out for this anomaly. Very rare defect alleles might have been involved in the development of these inborn defects.

    ABSTRACT: For many years, ruminant nutritionists and microbiologists have been interested in manipulating the microbial ecosystem of the rumen to improve production efficiency by domestic ruminants. Antibiotic ionophores have been used successfully for this purpose. However, the use of antibiotics in animal feeds has been banned in the European Union since January 2006 due to the risk of spreading antibiotic resistance. For this reason, scientists have become interested in evaluating other alternatives to control specific microbial populations to modulate rumen fermentation. Dietary supplements of live yeast preparations, based on Saccharomyces cerevisiae, have been reported to improve health and productivity of ruminants. In contrast to antimicrobial agents, live yeasts offer a natural alternative to manipulate animal performance. This review discusses the modes of action of live yeasts in rumen ecosystem and their subsequent effects on animal performance.

    ABSTRACT: Chronic endometritis can be diagnosed after three weeks post partum. Diagnostic methods such as external inspection and transrectal palpation of the uterus are not accurate enough to find each of the affected cows. An additional vaginal examination is more successful. Manual vaginal examination with the gloved hand or the use of a speculum will be sufficient. A new diagnostic device (Metricheck) seems to be suitable for the diagnosis of endometritis. For the evaluation of a given diagnostic test false-positive and false-negative diagnoses have to be considered. Ultrasonography is established in gynaecological examination in cattle and is adequate to diagnose endometritis accurately. Further diagnostic methods are cytological, histological and bacteriological examinations. Samples can be obtained by biopsy, uteruslavage, swabs or Cytobrush. Recently, precise clinical definitions of uterine diseases were adopted by several international researchers. These definitions should be used in national languages as well. Recent papers described cytological and ultrasonographical examinations for the diagnosis of subclinical endometritis.

    ABSTRACT: Two black and white female German Holstein calves showed malformations of the cerebrum. The first calf exhibited a cystencephaly and the second calf a meningoencephalocele. The animals originated from two different dairy farms. Both calves were sired by two unrelated sires used in artificial insemination. The calf affected by cystencephaly was lacking the corpus callosum which may had been caused the cystencephaly. Exept for a pressure atrophy, the remaining parts of the brain were macroscopically and histologically inconspicious. Histological examination of the cerebrum, brain stem and cerebellum in the second calf did not reveal specific changes. A further finding in the second calf was a unilateral anophthalmia. Both animals were affected by additional defects in the spinal column including brachyuria, duplications and fusions of vertebral bodies and rips as well as malformations of the heart such as ventricular-septal defects. Only mild clinical symptoms could be observed in both calves. The calves were not inbred and further calves affected by the identical anomalies could not be ascertained at the farms where the calves were born. Chromosomal anomalies could not be detected after examination of metaphase spreads using light microscopy.

    ABSTRACT: This report describes the macroscopic, histologic, immunohistologic and ultrastructural characteristics ofa biphasic malignant mesothelioma in the peritoneal and pleural cavity of a 13-year-old Icelandic pony mare, which exhibited recurrent ascites clinically. Immunohistology was performed employing multiple monoclonal antibodies against cytokeratins (CK) and vimentin. The ultrastructural examination included the quantitative evaluation of the length to diameter ratio of the microvilli. Post mortem examination revealed a severe ascites and hydrothorax. The serosal surfaces of the peritoneum and pleura displayed poorly-demarcated, multifocal to coalescing laminar masses and small nodules. Histology revealed a bimorphic mass consisting of spindle-shaped cells and microcystic epithelioid areas. A transcoelomic and local invasive growth pattern as well as lymph node metastases were noticed. Immunohistology revealed a strong expression of CK. Though a low and moderate expression of CK5/6 and CK20 was present, respectively, CK7 and CK10-antigens were lacking. Ultrastructurally, the epithelioid mesothelioma cells displayed long microvilli, cytoplasmic tonofilaments, and desmosomes. Quantitative evaluation of the length to diameter ratio of the 10 longest microvilli revealed a mean value of approximately 16.2. Summarized, this report described the case of a malignant biphasic mesothelioma with an atypical CK20 expression but a characteristic ultrastructural morphology including long microvilli.

    ABSTRACT: The aim of this study was to compare the effects of inorganic and organic selenium compounds supplementations to diets containing adequate selenium in broilers on performance, carcass traits, plasma and tissue glutathione peroxidase activity. A total of 150 one-day-old broilers were randomized into one control and two treatment groups each containing 50 birds; each group was then divided into 3 replicate groups. The experiment lasted 42 days. All groups were fed with broiler starter diet from day 1 to 21 and finisher diet from day 22 to 42. The basal diet for control group included adequate selenium due to vitamin-mineral premix and feeds. The basal diet was supplemented with 0.2 mg/kg organic selenium (selenomethionine, treatment group 1) and 0.2 mg/kg inorganic selenium (sodium selenite, treatment group 2). Although no significant differences were determined between treatment group 1 and the control group for mean body weights, the differences between the group given inorganic selenium and the other groups were statistically significant (p < 0.01). There was no significant difference between control and treatment groups with regard to mean feed intake and feed efficiency. The dressing percentages of the second treatment group were found to be lower than the first treatment group. Treatment groups were observed to have increased levels of glutathione peroxidase in plasma (p <0.01), kidney (p < 0.05), femoral muscle (p < 0.05), heart (p < 0.01) and liver tissue (p < 0.01) compared with the control group. Results of this study indicated that the supplementation of organic selenium to diets containing adequate selenium increased plasma, liver, femoral muscle, kidney and heart tissue glutathione peroxidase activity in broilers.
