The factors affecting the distribution of babesiosis in dogs in Poland

Abstract

The aim of this paper was to determine the factors affecting the development of canine babesiosis in Poland. The studies included 800 animals from 16 polish voivodeships-districts (50 from each voivodeship) with suspected piroplasmosis. Hematological and molecular tests confirmed infections in 158 animals. Analysis of the genetic material using the Real-Time Sybr Green HRM technique showed that 96 dogs were infected with Babesia canis 18S RNA-A and 62 with B. canis 18S RNA-B. It was observed that the disease occurs more often in eastern Poland (OR: 8.91; CI: 5.7-13.8), in males (OR: 1.04; CI: 0.7-1.5) and especially in rural areas (OR: 1.7; CI: 1.2-2.4). More prone to infection were pure-bred dogs (OR: 2.24; CI: 1.6-3.2), young animals under 1 year old (OR: 0.73; CI: 0.4-1.5), animals that had suffered from babesiosis in the past (OR: 17.9; CI: 10.9-29.2) and those that had not received preventive measures against ectoparasites (OR: 0.32; CI: 0.2-0.5). Knowledge of the factors facilitating the development of canine babesiosis helps to understand the causal connection between the dogs' exposure to the pathogen and the development of the disease and to limit the occurrence of the infection in these animals, to diagnose it early and to start proper treatment before serious complications develop.
