Chrysocyon brachyurus, the largest South American canid, is a native species of the Brazilian cerrado. The present study is aimed to report the occurrence of the trematode, Athesmia foxi, in the liver of a new host, C. brachyurus, and to describe its morphology and pathology. One C. brachyurus individual was necropsied and examined for the presence of parasites. Worms were collected from the bile ducts and based on morphological and morphometrical characteristics, such as a relatively large, slender, aspinose, elongated shape with vitellarium present on the upper left side of the body were identified as A. foxi. On the host, hepatic lesions limited to the bile ducts and periportal regions, were characterized as chronic-active cholangitis, biliary hyperplasia, and fibrosis. This is the first report of A. foxi parasitizing C. brachyurus, demonstrating that this parasite has no host specificity and can be widely distributed. A. foxi lesions noted in C. brachyurus are similar to those noted in various other mammalian hosts.

Dirofilariosis belongs to zoonotic vector-borne diseases with fastest spread into new areas caused by extreme weather and seasonal changes in climate. In Slovakia, Dirofilaria spp. parasites affect more than 30 % of dogs living in endemic regions in southern parts of territory, however, data on wildlife circulation of this parasite are still scarce. In order to clarify the role of red fox (Vulpes vulpes) as the most abundant canid species in Europe in maintaining the parasite in natural foci, an initial survey of dirofilariosis in this carnivore species was conducted in Slovakia. The samples of 183 red foxes hunted in 2007 - 2009 in regions of South-Eastern and Northern Slovakia with different geographical and climate characteristics were examined by means of PCR method using specific D. repens, D. immitis and Acantocheilonema recognitum primers. The DNA was isolated from spleen samples using commercial kit and PCR approach was used for diagnostics. After amplification selected products were purified and sequenced to elucidate any homologies with previously deposited sequences in Gen Bank. The results showed 105 out of 183 examined specimens (57.4 %) being infected, with great regional differences in prevalence. Phylogenetic relationships within Dirofilaria species indicate that obtained isolates belong to D. repens. The results confirmed the role of red foxes as the reservoir of parasite. Herein, epidemiological factors that may be coherent with the Dirofilaria parasites distribution and circulation in wildlife and implications in risk assessment and prevention for domestic animals and human are discussed.

The main goal of the current research includes studying the biological signal field (BSF) characteristics of the wolf (Canis lupus lupus Linnaeus, 1758) at different values of anthropogenic load on territories with conservation (Białowieża National park (Poland)) and hunting status of the species (Chornobyl Exclusion Zone (Ukraine)). The research in Białowieża Primeval Forest was conducted in two stages: study of the BSF characteristics of the wolf and finding correlation between data acquired from Ukraine (the first stage), and over-time study of intensity of the biological signal field (the second stage). In result of the first stage, there was no significant dependence on the characteristics of the territory and the differences between the behavior of wolves in the Białowieża Primeval Forest (conservation status of the species) and the Exclusion Zone (game status). During the second stage it was determined that provided variance of the intensity between territory groups was insufficient, the degree of significance to animals of area categories varied with the stages of the pack’s life. It was found that the main factors which govern the character of wolf activity are not the level of the anthropic load and hunting pressure, but periods of the life cycle and spatial structure of groups.
The research was carried out in 6 territories located in oak forests of Slobozhanshchyna in 2007–2016. Family home ranges were determined using the average nearest neighbour distance between all setts of a sett system for the badgers and between breeding burrows for the foxes. The use of fox and badger family home ranges in different seasons and years was estimated by changes in the use of burrows at the monitoring site of Gomilshanski Lisy National Nature Park. In the oak forests, 173 burrows were studied, among which 75 are used by badgers and 45 by foxes. The area of most of the badger family home ranges in the oak forests is 28–88 hа. The area of the fox family home ranges in the oak forests is 86 to 892 ha. In the oak forests of Slobozhanshchyna, badger and fox family home ranges correspond to the data for similar biotopes in Europe. Seasonal changes of the badger family home range used at the monitoring site in Gomilshanski Lisy NNP in general correspond to literature radio tracking data. Changes in use of the fox family home range de pend on fluctuations of the abundance of rodents.
