Gastro-intestinal parasites are extremely important pathogens of humans, domestic livestock, and wild animals. Parasitological prevention in wild ruminants was conducted in forests of eastern Poland in early spring from 2009 to 2013. Fenbendazol in a single-dose (5 mg/kg BW) mixed with feed was distributed through forest feeders. Fecal material was collected in the vicinity of the feeders on the day before the treatment (D0) and 14 days after the treatment (D14). To determine the occurrence of gastrointestinal parasites, coproscopic analysis was conducted by the flotation method and McMaster’s method. Parasite species were identified morphologically on the basis of eggs. The fecal samples contained eggs of the nematodes Trichostrongylidae, Chabertidae, Bunostomum, Nematodirus spp.; Trichuris spp.; Strongyloides spp., and an oocyst from the genus Eimeria spp. Nematodes from the Trichostrongylidae family showed the highest prevalence and intensity (prevalence in 2010 = 74.2% [63.7-82.7], EPG in 2009 = 2750) throughout the study. The prevalence of the other taxa varied over the study period: Nematodirus spp. 34.1-77.4%; Trichuris spp. 1.6-17.7%; Strongyloides spp. 0-22.6%, and Eimeria spp. 23.6-51.6%. No statistically significant differences were shown in the occurrence of gastrointestinal parasites before (D0) and after treatment (D14). However, a marked reduction in the prevalence of all gastrointestinal parasites was demonstrated over the five years of the study (treatment efficacy of 66-78% in parasite reduction). There was a significant difference in the EPG of Trichostrongylidae, Chabertidae, Bunostomum (EPG reduction of 71-83%) and Nematodirus spp. (EPG reduction of 70-75%) before and after treatment (U₍₈₎ = 1; P < 0.05; U₍₈₎ = 0; P < 0.05, respectively for family).Changes in the EPG of Trichuris and Strongyloides genus were not significant. In conclusion, it is worth considering parasitic prevention in wild ruminants, which may positively influence animal health, immunity status, and the quality of kill. Moreover, natural deworming in combination with chemical prevention may significantly reduce the contamination of the environmental with parasite eggs.

The aim of this study was to compare the prevalence of selected pathogens in ticks taken from cats and dogs and from vegetation in urban settlements. A study was conducted to estimate the distribution of Anaplasma phagocytophilum and Borrelia burgdorferi in adult Ixodes ricinus (236), Dermacentor reticulatus (237) and Ixodes hexagonus (3) ticks collected from animals in veterinary clinics (184) and from vegetation in urban settlements (292). The most numerous ticks collected from animals were Ixodes ricinus (73.9%), followed by Dermacentor reticulatus (24.5%) and Ixodes hexagonus (1.6%). A total of 65.8% of the ticks collected from vegetation were Dermacentor reticulatus and 30% were Ixodes ricinus. The arthropods removed from the animals were most commonly located around the neck (48.1%) and in the mouth area (17.1%). All ticks were analyzed by molecular techniques. The percentages of ticks positive for Borrelia burgdorferi and Anaplasma phagocytophilum among those collected from animals differed from the corresponding rates for ticks taken from vegetation in the same area. Anaplasma phagocytophilum was more common in ticks collected from vegetation (N = 137, or 47.20%) than in those from animals (N = 12, or 6.6%). Borrelia burgdorferi, as well, was more common in ticks collected from the vegetation (N = 96, or 32.9%) than in those from animals (N = 19, or 10.5%). The DNA of A. phagocytophilum and B. burgdorferi were detected in 30.4% and 22.8% of D. reticulatus ticks, respectively, and in 32.6% and 25.4% of I. ricinus ticks, respectively. The DNA of A. phagocytophilum was also found in one Ixodes hexagonus tick. Single infections were noted in 69 I. ricinus ticks, 56 D. reticulatus ticks and 1 I. hexagonus tick. Coinfections of A. phagocytophilum with B. burgdorferi were detected in 33 (14.0%) I. ricinus ticks and in 29 (12.24%) D. reticulatus ticks. Infected companion animals can form a reservoir for human tick-transmitted infectious agents. The monitoring of the pathogens transmitted by ticks is an important tool in preventing and combating infections transmitted to humans and animals.
