Evaluation of gastrointestinal helminths in canine population of Bhubaneswar, Odisha, India: A public health appraisal

Abstract

Aim: To evaluate the presence of gastrointestinal helminthic parasites in clinically apparent canines of Bhubaneswar, Odisha and to determine the risk of zoonotic infection to dog owners through questionnaire survey. Materials and Methods: A total of 154 dogs, with clinical signs of gastroenteritis were examined for the presence of helminthic ova and /or larvae in their faecal sample by direct smear and/ or floatation and centrifugation method. Prevalence was determined by sex wise, age wise, and breed wise. A structured questionnaire on 50 dog owners was designed to gather information on dog ownership, management and related risks on public health. Results: In the present investigation, the overall prevalence of gastrointestinal helminths infection was 41.46%. The infection rate was highest for mixed parasitic infection (26.57%) followed by Ancylostoma caninum (23.44%), Toxocara canis (20.31%) and lowest for Taenia spp. (3.13%). In relation to different groups, the prevalence was higher in male than female, highest in younger animals and it was shown a decreasing trend as age increased. It was also higher in non-descriptive breeds than pure and exotic breeds. Very few dog owners (10%) were conscious about that canine parasite could be transmitted to humans but none of them could provide correct information on the mode of transmission. Only 12 % dog owners had maintained standard deworming schedule. Conclusion: The findings showed that the high levels of ignorance among dog owners about canine helminthic parasites and transmission coupled with significant infection rates among the dogs in the community warrants immediate action needs to be taken to decrease infection rate in dogs and to raise awareness among the community about zoonotic diseases.
