Monthly flea collections were made from domestic dogs in Bulloch County, Georgia, USA from September 1996 to August 2004. A total of 2518 fleas belonging to 8 species were collected. The most common flea was the cat flea, Ctenocephalides felis (389 males and 1148 females), followed by the dog flea, Ctenocephalides canis (250 males and 285 females), a generalist/carnivore flea, Pulex simulans (106 males and 213 females), and a sticktight flea, Echidnophaga gallinacea (3 males and 89 females). Small numbers of rabbit-associated fleas (25 Cediopsylla simplex and 6 Odontopsyllus multispinosus) and rodent-associated fleas (3 Orchopeas howardi and 1 Polygenis gwyni), suggested that certain dogs had acquired these particular ectoparasites through hunting activities. Sex ratios of each of the five most frequently collected flea species were female-biased. Seasonally, C. felis, C. canis, and P. simulans, all showed distinct abundance peaks in late summer or autumn.

Due to the frequency of parasitism and the medical consequences, regular flea control is advised on both dogs and cats (Beugnet and Franc, 2012; Otranto et al., 2009a,b). "

    ABSTRACT: Ctenocephalides fleas are not only the most prevalent ectoparasites of dogs and cats but also the intermediate host of the cestode Dipylidium caninum. Due to the poor sensitivity of coproscopy to diagnose cat and dog infestation by Dipylidium, few epidemiological data are available on its prevalence among pet populations. A new PCR method was developed to specifically identify D. caninum rDNA inside single fleas. The PCR test was then applied to 5529 fleas of Ctenocephalides genus, 2701 Ctenocephalides felis fleas (1969 collected on 435 cats and 732 on 178 dogs) and 2828 Ctenocephalides canis fleas collected from 396 dogs. Precisely, 4.37% of cats were infested by a flea population infected with D. caninum. Out of the 1969 C. felis from cats, 2.23% were found to be infected with Dipylidium. From the 396 dogs infested with C. canis, 9.1%% were infested with the Dipylidium infected fleas, which is significantly higher than the observation made in cats (p=0.03). Moreover, 3.1% of the C. canis fleas were found to be infected with Dipylidium, which is not significantly different than in C. felis. Looking at the number of infected fleas in the positive samples (at least one PCR positive flea in a sample), the infestation rate in samples was varied from 3 to 100% with an average of 19.7% which is in favour of easy and regular Dipylidium reinfestations of both cats and dogs in households. For the first time, the spread of D. caninum between fleas and dogs and cats is confirmed throughout Europe.

    • "C. canis has been reported as the main flea species infesting dogs in several countries, including Ireland and Greece (Baker and Hatch, 1972; Koutinas et al., 1995; Xhaxhiu et al., 2009; Farkas et al., 2009; Chee et al., 2008; Guzman, 1984; Gonzales et al., 2004; Alcaino et al., 2002). In addition , in areas where C. felis appears to be predominant, C. canis still represents a significant proportion of fleas in dog populations with a prevalence of 10–12.5% in Europe and up to 21% in the USA (Franc et al., 1998; Gracia et al., 2007; Beck et al., 2006; Durden et al., 2005). The goal of a successful flea control program is to eliminate fleas quickly, continuously, and to prevent them from producing viable eggs that contaminate the environment. "

    ABSTRACT: The efficacy of orally administered afoxolaner against adult dog fleas, Ctenocephalides canis, was evaluated in a controlled, blinded study. A total of 32 dogs were infested with 100 adult unfed fleas approximately 24 h prior to treatment and then at weekly intervals for 5 weeks after treatment. Live fleas were counted upon removal at 12 h (for 16 dogs) and 24 h (for the remaining 16 dogs) after treatment (for counts performed the first week) or after infestation (for counts performed on subsequent weeks). In addition, flea eggs were collected from each pen and counted for the dogs with flea removal at 24 h. Dosing of individual dogs was achieved using a combination of the chewable tablets to be as close as possible to the minimum effective dose of 2.5 mg/kg. The percent efficacy of the afoxolaner treatment was ≥99.0% for all 24-h flea counts. For flea counts performed 12 h after treatment or infestations, the percent efficacy was ≥94.1% up to Day 21. After Day 1, no flea eggs were recovered from the afoxolaner treated group, providing 100% reduction in numbers of flea eggs recovered versus untreated control group. This study confirmed that a single oral treatment with afoxolaner provided excellent efficacy against infestations by C. canis within 12–24 h after treatment, prevented re-infestations, and completely prevented egg production from new flea infestations for up to 5 weeks.

    • "It appears from the Table 1 that all age groups of dogs are affected with lice, tick, flea and mites but only mange mites showed significantly (p > 0.05) higher prevalence in dogs above 36 months (2.34%) in comparison to aged between 7 to 36 months (1.36%) and up to 6 months (0.05%) age groups (Table 1). However, higher prevalence rate of fleas and mange mites have been reported elsewhere (Rodriguez-Vivas et al., 2003; Durden et al., 2005) who reported Demodex canis (23.0%) as a most frequent mite, followed by Sarcoptes scabei var canis (7.0%) and Otodectes cynotis (3.5%) in Mexico. Seasonal frequency of ectoparasites infestations has also been reported (Shoorijeh et al., 2008). "

    ABSTRACT: A case control study was conducted to ascertain the prevalence of clinical diseases and/or clinical conditions of 3670 sick pet dogs presented to the Central Veterinary Hospital (CVH), Dhaka during the one year period from January to December 2009. A total of 57 types of diseases and conditions in 17 categories were recorded in these pet dogs and their variation in prevalence were analyzed on the basis of age, gender, season and breeds of dogs. The prevalent diseases and/or conditions from low to high rates included glaucoma (0.05%), babesiosis (0.08%), sinusitis (0.08%), tetanus (0.08%), spaying (0.14%), nail injury (0.19%), nephritis (0.19%), cataract (0.25%), metritis (0.25%), poisoning (0.33%), orchitis (0.35%), rabies (0.35%), pus in antrum (0.41%), purulent cough (0.46%), alopecia (0.52%), pharyngitis (0.52%), transmissible venereal tumor (0.54%), cystitis (0.52%) phimosis (0.52%), paraphimosis (0.60%), stomatitis (0.63%), pneumonia (0.63%), mastitis (0.71%), otitis (0.73%), taeniasis (0.74%), abscess (0.82%), anal gland disease (0.82%), dystocia (0.84%), conjunctivitis (0.90%), lice infestation (0.90%), lameness (0.95%), ottorrhea (1.06%), uterine prolapse (1.31%), posthitis (1.31%), dental disorders (1.34%), metabolic diseases (1.36%), protrusion of eye ball (1.44%), canine distemper (1.61%), liver disease (1.72%), nutritional deficiency diseases (1.77%), infertility (1.80%), coccidiosis (1.93%), toxocariasis (1.93%), urinary tract infection (2.10%), accidental wounds (2.32%), haematuria (2.34%), bronchitis (2.81%), arthritis (2.94%), dermatomycosis (3.30%), aspiration pneumonia (3.32%), mange (3.76%), echinococcosis (3.92%), dermatitis (4.99%), diarrhea (5.21%), ancylolostomiasis (6.20%), flea infestation (9.84%) and tick infestation (11.88%). Age-wise overall prevalence of clinical diseases revealed significantly (p <0.05) highest in age group above 36 months (48.12%) compared to that in 7 to 36 months (34.33%) and up to 6 months (17.55%) age groups of pet dogs. The significantly (p <0.05) highest prevalence of diseases and/or clinical conditions was recorded in local (33.35%) and German shepherd (22.53%) breeds of pet dogs in comparison to that in their counterpart breeds of Lhasa-Apso (7.57%), Greyhound (7.11%), Doberman (6.34%), Samoyed (6.23%), Dachshunds (5.20%), Spaniel (3.37%), Spitz (3.07%) and Poodle (3.18%). Results from season-wise analysis of overall prevalence of diseases and/or clinical conditions in pet dogs did not differ significantly (p >0.05) among spring (21.53%), summer (25.80%), autumn (22.83%) and winter (29.84%). The highest prevalence of arthropode infestation (22.62%), followed by intestinal parasitic diseases (14.80%) and diarrhea (5.20%) suggest a poor husbandry of these pets in Dhaka. Results of this study indicate that the risk of zoonotic infection by canine intestinal parasite may be high in Bangladesh.
