Spread and Seasonal Dynamics of Toxocarosis in Dogs in the Republic of Tajikistan

Abstract

The purpose of the research is to study the spread and seasonal dynamics of toxocarosis in domestic and police dogs in the Republic of Tajikistan.Materials and methods. In order to study the period of maximum Toxocara sp. infection and seasonal dynamics of toxocarosis, monthly records were kept for dogs diagnosed with toxocarosis in a population of both domestic and police dogs from September 2016 to February 2019. We examined 70 dogs, of these 41 were police dogs and 29 were domestic dogs. 334 fecal specimens of police dogs and 221 fecal specimens of domestic dogs were examined by the Fulleborn flotation method.Results and discussion. 75 (22.3%) fecal specimens of police dogs from 336 fecal specimens studied were found to have Toxocara sp. eggs, and Toxocara sp. eggs were found in 28 (12.6%) fecal specimens of domestic dogs from 221 dogs studied. Toxocarosis in domestic dogs was reported throughout the year. The maximum Toxocara sp. infection in dogs was established in winter (28.5%) and summer (29.6%) 2017, and in summer (38.0%) and spring (31.8%) 2018, and in spring (28.5%) 2019. Toxocara sp. occurrence in police dogs and dogs belonging to breeding kennels of various institutions accounts for 4–8 age group. Dogs of younger age were infected with Toxocara sp. to a lesser degree.
