The aim of this study was to evaluate Eprinex Pour-On against gastro-intestinal nematodes in naturally infected goats. Two groups, each including adults and one-year old goats were treated with standard bovine dose and double dose rate. The prevalence and intensity of gastro-intestinal nematodes infection was determined based on faecal samples examination on the day of treatment (day 0) and 7,14,34, 56,90 and 125 days after the treatment. The low efficacy of the recommended bovine dose rate was stated within the first two weeks after the treatment (59.5% and 89.9% in adults and yearlings, respectively). In double dosed animals, the efficacy was 97.6% and 88.5% on the 56th day after dosing in adults and young, respectively. The results of the study demonstrate the high and persistent efficacy of Eprinex against gastro-intestinal nematodes in goats in a double bovine dose rate. They also indicate the dose is highly effective against the mucosal stages of goats’ nematodes.

The aim of the present survey was to determine the distribution of Trichinella species in red foxes in Poland. Muscles have been collected from 1282 red foxes (Vulpes vulpes) killed by hunters in different regions of Poland between 1995 and 1999. Trichinella larvae have been collected after artificial digestion of muscles and preserved in absolute ethyl alcohol before molecular identification. Random amplified polymorphic DNA analysis and two other polymerase chain reaction (PCR)-based analyses have been used to identify larvae at the species level. The overall prevalence of infection was found to be 5.7% (73/1282 examined foxes), but larvae from only 44 foxes could be recovered for species identification. From these, thirty-two foxes (72.7%) harboured T. britovi, five (11.4%) had T. spiralis, four (9.1%) showed a mixed infection with the two species. The DNA of larvae from three (6.8%) animals did not showed reproducible results. This study shows T. britovi as the most important etiological agent of sylvatic trichinellosis in almost the whole territory of Poland and the role of red fox in the maintenance of this parasite in nature.

The work involved the necropsy of 28 deer (9 red deer, 1 maral, 1 Eld’s deer, 1 Pere David’s deer and 16 fallow deer), as well as coproscopic study of several hundred faecal samples. A total of 23 nematode species and one tapeworm species were discovered. All the deer studied had nematode infections in their abomasum and it was the number of such parasites which was greatest (up to 17,960 individuals per deer). The richest species composition also related to abomasal nematodes, with 13 species noted. Of the parasites recorded, only two (O. drozdzi/O. ryjikovi and S. suppereri) were first records for Poland, with the remaining 21 being common parasites of deer inhabiting the country’s open hunting grounds. Evidence for the very considerable exchange of parasites between red deer and fallow deer was noted and the co-occurrence of these species has clearly exerted a significant influence on their helminthofaunas, whose species compositions are very similar. In spite of this, there are clear differences in the prevalence, intensity and percentage index of intensity of some infections.

On the basis of the fecal egg counts, larval cultures and necropsies the infection of coccidia, tapeworms and gastrointestinal nematodes in dams and lambs under extensive and intensive management systems were estimated. During 1994 and 1995 total of 1740 coproscopic analyses were done. It was state, that in extensive farms the prevalence and EPG of gastrointestinal nematodes was higher in comparison with intensive management system (38.2-86% and 13.9-71.9% and 105-355 EPG and 33-131 EPG respectively). Similarly prevalence of tapeworms 0-18.2% and 1.3-8.3% respectively. Prevalence and intensity of coccidia was lower in extensive farms (20-78,5% and 83-482 OPG) comparing with intensive management system (38.2-88% and 139-2846 OPG). Predominant nematode species in both management systems were those from genes Haemonchus, Teladorsagia, Trichostrongylus, Cooperia and Nematodirus. One species - Nematodirus battus was found new for Poland.
