  With the increasing trends of pet ownership the chances of campylobacteriosis are also increasing as these pets are kept in close visicinity of owners. The prevalence and antimicrobial sensitivity profiles of Campylobacter isolates from faeces of dogs attended in veterinary practice at Teaching Veterinary Clinical Complex, Mathura, India. During the period of investigation (October 2009 to April 2010), 100 rectal swabs from dogs were collected and transported to the laboratory for further investigations. Bacteriological examination revealed 51.00% prevalence rate of Campylobacter isolates in dogs faecal samples. The disc-diffusion method was used to know the susceptibility of all the 51 Campylobacter isolates against 10 commonly used antimicrobials in pet animal practice. High rates of resistance were observed to erythromycin (90.20%), tetracycline (88.23%), ampi-cloxacillin (88.23%), ciprofloxacin (80.39%), enrofloxacin (68.63%) and aymoxycillin-clavulanic acid (19.61%). All the Campylobacter isolates were susceptible to amikacin, levofloxacin and streptomycin. Erythromycin and ciprofloxacin are drugs for treatment of human campylobacteriosis. The high resistance rate to these drugs among Campylobacter isolates from dog faeces is of public health significance as dogs are supposed to be the main source of infection in human beings.

  Campylobacteriosis is one of the leading causes of gastroenteritis in humans and various researches suggested that owning a pet is a risk factor for the disease. To determine the prevalence and risk indicators for Campylobacter sp. infecting dogs attending veterinary practice at TVCC, DUVASU, Mathura, 100 dogs with and without the clinical symptoms of diarrhoea were examined and the prevalence of Campylobacter sp. was 51.0%. Breed wise prevalence showed that nondescript (73.68%) dogs were more likely to carry Campylobacter sp. A significant difference in isolation rates was observed between younger and older dogs: 56.58% of the younger dogs (≤ 1 year) were positive, compared with 33.33% of adult dogs (> 1 year) (p<0.01) as seen at the veterinary University, Mathura, India. Dogs sharing a household with another dog, dogs that had not received antibiotic treatment in the previous months and the age of the dog were significant indicators of Campylobacter carriage. Recent diarrhoea or vomiting in dogs with Campylobacter, breed, sex or vaccination status were not statistically significant. The high prevalence of Campylobacter in puppies supports the hypothesis that dogs, particularly young ones shed Campylobacter spp., which can be of impact for public health.

  Toxocara canis is a very important gastrointestinal nematode affecting canines with considerable public health importance. This study was conducted to find out the prevalence and corresponding haemato-biochemical changes in dogs infested with T. canis and to determine its zoonotic implication to dog owners. A total of 121 dogs were screened from October 2008 to May 2009 by direct smear and Mc-master technique, to determine correlation between overall prevalence of T. canis infestation with respect to sex, age, breed, size and season-wise infestation. Haemato-biochemical profile was performed in 24 infested dogs, randomly selected to evaluate changes in Hb, PCV, TEC, TLC, DLC count, serum protein, serum glucose and serum enzymes. The overall prevalence was found to be 28.93%. The prevalence was not influenced by sex but non-descript breeds had significantly higher rates. Pups were more infested than adults and the disease was more prevalent in winters. Dogs having active infection with T. canis infestation showed anemia, leucocytosis and significant eosinophilia (p<0.05). A significant decrease (p<0.05) was observed in serum protein and glucose whereas highly significant increase (p<0.01) was found for both serum enzymes (SGOT and SGPT). Very few dog owners (4.13%) were aware about potential public health significance of the parasite. Survey revealed that unaware owners who belonged to lower/middle/upper middle class, did not maintain hygiene and scheduled deworming and always remain at high zoonotic risk. Being zoonotic, the parasite poses a significant danger to humans mainly children who remain in their vicinity. Thus immediate action needs to be taken to control this parasite and to increase awareness among the dog-owners about the zoonoses being spread by the companion animals.
