Background: Dirofilaria immitis is vector borne parasite of carnivores, with zoonotic potential, endemic in many parts of the world, including Europe. The aim of this study was to determine the prevalence of Dirofilaria immitis infection in dogs from shelters, especially compared to their lifestyle. Dogs living in shelters in Serbia may be at high risk of acquiring vector borne pathogens, mainly because most of them live outside in pens and backyards, in contact with vectors. Also, dogs in shelters are not always regularly treated against ectoparasites, thus, representing an easy feeding source for the vectors. The objective of this study was to determine the prevalence of Dirofilaria immitis infection in dogs from 5 shelters in South Bačka and Central Banat districts, in Autonomous Province of Vojvodina, Northern part of Serbia. Also, the objective was to compare the relation of infection with Dirofiaria immitis with age, sex, type of keeping the animals and preventive treatment in dogs. Materials, Methods & Results: Between May 2017 and October 2019, blood samples were collected from 336 randomly selected dogs from 5 shelters in 2 districts, South Bačka and Central Banat districts, in Autonomous Province of Vojvodina, Northern part of Serbia. The epidemiological survey has been conducted with all of the dogs involved in this research. The survey was designed to collect data about sex, age, lifestyles, food type, treatment against mosquitoes with insecticides and filarioid worms with macrocyclic lactones, regular testing for Dirofilaria infections. The presence of circulating microfilariae was examined using a modified Knotts test. For the presence of circulating adult female Dirofilaria immitis antigen, serum samples were tested by commercially available enzyme-linked immunosorbent assay, which reacts to antigen of female Dirofilaria. In total, 336 dogs were examined for the presence of Dirofilaria...(AU)
