猫における消化管線虫の有病率、危険因子、および人獣共通感染症の可能性：参加型疫学研究

Domestic cats are the only felines living exclusively with humans, making them ecologically invasive and widespread across terrestrial habitats. Their domestication stems from their rodent control abilities and companionship. However, they are susceptible to gastrointestinal parasites such as Ancylostoma spp., Toxocara cati, and Dipylidium caninum, causing issues like anaemia, vomiting, and sometimes death, especially in kittens. These parasites can also pose zoonotic risks, transmitting diseases like visceral and ocular larva migrants to humans. A total of 100 cats with no deworming history were examined over six months. The overall prevalence of intestinal helminths was 23.0%, with Ancylostoma spp. being the most common (11.0%), followed by Toxocara cati (7.0%), Taenia spp. (2.0%), and mixed infections (3.0%). The prevalence was higher in females (26.92%) than in males (18.75%). Age-wise, kittens under 6 months had the highest infection rate (36.17%), while cats aged 6-12 months showed the lowest (10.71%). Non-descriptive breeds exhibited a higher infection rate (34.88%) than descriptive breeds (14.03%). Most cats were kept in confined spaces (72.0%), with 57.0% being descriptive breeds. Cats were mostly fed a mix of cooked and commercial cat food (59.0%), while only 33.0% were vaccinated and 20.0% dewormed. Behavioural issues like licking (51.0%) and self-biting (13.0%) were noted. Only 41.0% of owners were aware of zoonotic disease risks from cats. Chi-square analysis revealed significant associations between infection rates and risk factors (variables) such as breed, age, diet, vaccination, and deworming status. Non-descriptive breeds, unvaccinated cats, and those fed vegetarian diets had significantly higher infection rates (p < 0.05). Unconfined housing also contributed to increased infection risk, though not statistically significant. The research was significant because it highlighted the public health risks, as many cat owners and pet lovers were unaware of the zoonotic potential of intestinal helminths in cats.
