Clinical-parasitological Screening for Respiratory Capillariosis in Cats in Urban Environments.

Respiratory capillariosis is a widely distributed zoonotic parasitic disease caused by the nematode Capillaria aerophila (Trichocephalida, Trichuridae) that commonly infects wild carnivores but also cats and dogs. This retrospective study aims to describe cases of respiratory capillariosis in cats from the city of Belgrade, Serbia. Between 2015 and 2019, a total of 155 pet cats with or without respiratory symptoms were submitted to physical examination and parasitological examination of the feces. All cats lived indoor but had free access to outdoor. In suburban settlements, wild carnivores commonly share their living environments with owned cats and dogs. It can be assumed that more intense urbanization spreading into the natural habitats of will carnivores creates the opportunity for closer and more frequent contacts between the population of cats and feral carnivores which might increase the risk of feline contamination. The findings confirm the existence of capillaries in cats in urban areas of the city of Belgrade, contribute to a better understanding of the epidemiology of this nematode and warn that, because of close contacts between cats of pets and humans, capillaries can cause human infection.

Soil and Sand Contamination with Canine Intestinal Parasite Eggs as a Risk Factor for Human Health in Public Parks in Nis (Serbia).

Regarding geographical distribution and clinical relevance, the most common canine geohelminths are Toxocara canis, ancylostomatids, and Trichuris vulpis. Canine intestinal parasites from the soil and sand present an important potential serious human health hazard, especially for the children preschool and school - age. This paper aimed to establish the degree of contamination of soil and sand with zoonotic parasites from the canine feces and the degree of risk they could pose for human health in public places and playgrounds in the city of Nis. Our parasitological study involved 200 soil samples and 50 sand samples from the public parks in the city of Nis in southeastern Serbia (43°19'15″N, 21°53'45″ E). From several locations, about 100 g of soil and sand was collected based on the bioclimatic indices. Parasitological diagnosis was performed using conventional qualitative and quantitative coprological methods, abiding by the recommendations about the diagnosis of parasitic diseases. In 38 - 46 % of soil samples and 40 % of sand samples seven species of endoparasites were diagnosed. In the samples of soil, a medium and high degree of contamination with the ascarid T. canis (14 - 22 %) was detected, as well as a low and medium degree of contamination with ancylostomatids (4 - 12 %), and in the samples of sand, a variable degree of contamination with the helminths T. canis (26 %) and A. alata (16 %) was found. A statistically significant difference was found in the contamination with A. alata eggs between the samples of sand and samples of soil. The studied public surfaces represent the reservoir of zoonotic parasites, which is a public health problem requiring a synergistic action of several factors to be successfully resolved, i.e. the implementation of prevention, surveillance, and control measures.

Improving agricultural production of domestic rabbits in Serbia by follow-up study of their parasitic infections.

A study was made on the prevalence of some parasitic infections appearing in domestic rabbits obtained from individual breeders in Serbia in order to improve the agricultural production of these animals. Aside from economic reasons (meat production and reproduction) rabbits are bred for the research purposes, and races are kept as household pets. For these reasons, among others, it is important to gain knowledge of medical culprits including causes of parasitic diseases that compromise their health, well-being and cause economic losses. This parasitological research was conducted in the period from 2010 to 2015 in 8 epidemiological regions of Serbia, on 433 rabbits as representative samples of different races (154 individuals up to 1 years of age and 279 individuals older than 5). Out of the total number of examined rabbits parasitic infections were established in 82.68% of animals. We detected 3 species of endoparasites (Eimeria spp., Trichostrongylus spp., and Passalurus ambiguus) and 3 species of ectoparasites (Scabies from genera Sarcoptes, Psoroptes and Notoedres). In "kits" (small rabbits) coccidiosis was the most prevalent disease (50.65%), while in older animals trichostrongilidosis was common (39.07%). The most represented scabies infection was with the species Psoroptes cuniculi (12.01%). Aiming at better control on the health of rabbits, there is a growing need for continual monitoring of parasitic infections including appropriate diagnosis, application efficient therapeutic protocols and control measures.
