On the basis of the faecal egg counts (epg), the effect of intestinal nematode infection on the productive traits of gilts fattened at Pig Testing Stations (PTS) during 1994-1995 was evaluated. Presumably due to a full-constituent pelleted feed mixture given ad libitum, only in some cases the infection significantly lowered the daily gain, feed convertion or meat content in carcass of gilts, and in some - the phenomenon of resilience was observed. The highest influence on the productivity had station factors.
The intestinal helminth fauna of 201 specimens of Vulpes vulpes, captured in Galicia (northwest Spain), was investigated. Eight species were found: Toxocara canis (23% of host specimens), Toxocara cali (0.5%), Toxascaris leonina (1%), Uncinaria stenocephala (28%), Seuratascaris numidica (0.5%), Taenia crassiceps (23%), Mesocestoides litteralus (2.5%) and Dipylidium caninum (0.5%). We discuss possible relationships between human population density and the prevalence of infection of fox by intestinal helminths.

Prevalence of intestinal nematodes in dogs from Warsaw region. Investigation of prevalence of intestinal parasites in dogs bave been conducted in order to protect human and animal health. The aim of the study was to establish species composition of intestinal parasites and to evaluate their prevalece in dogs from the shelter in Józefów situated on north from Warsaw. Additionally, urban dogs from Warsaw and village dogs from areas near the shelter, were examined. The prevalence of nematodes was: 62.3% in dogs from shelter, 37.5% in village dogs and 18.8% in urban dogs. In homeless dogs, the most common parasite was Uncinaria stenocephafa, then Trichuris vulpis and Toxarcaris leonina. In village dogs only eggs of U. stenocephala were detected; in urban dogs Toxocara canis and U. stenocephala were found.
Studies on the efficacy of Banminth, Eqvalan, Panacur Paste and Rintal Plus against small strongyles (Cyathostominae) in horses were carried out on 39 adult mares. The FECRT test indicated a reduction to about 85.0% in the efficacy of Panacur Paste and only 43.3% of Rintal Plus. The efficacy of Banminth and Eqvalan was, at the same time, very high - up to 100%. It is worth noting that in the stable used in the experiment, as well as in others, it would be necessary to change the drug used for nematodes control.
It was found that the addition of one of the following fertilizers, i.e. urea, Norway salt-petre, nitro-chalk or ,,Polifoska” to sheep faeces restricted the development of larvae, while the invasive larvae stored in solutions of mineral fertilizers or CuSC4 at a concentration of 1 g per 100, 200 and 400 ml of water, or 1:1000 and 1:2000 in the case of CuSC4, died within a dozen or so hours.
The aim of the study was to evaluate the level of intestinal parasitic infection in bison (Bison bison L.) in a private farm located in southern Poland. The prevalence of infection [%] and the faecal oocyst/egg output in OPG (oocysts per gram) and EPG (eggs per gram) were estimated on the basis of coproscopic examination. The results showed a high occurrence of coccidia (Eimeria spp.) – 68.2% (347 OPG), as well as nematodes – 65.9% (93 EPG), with the Nematodirus genus observed in 6.8% of the animals examined. Among other nematodes, Toxocara (Neoascaris) vitulorum was found in 6.1% (10 EPG) of the animals. Trichuris ovis and Strongyloides papillosus occurred rarely (0.8%). Tapeworms, Moniezia spp., were noted in 9.1% of the animals. The primary factor conducive to the spread of gastrointestinal parasitic infections in the herd were wet pastures created in dried fish ponds, where protozoan oocysts and helminth eggs had excellent conditions for development and infection. The small number of large quarters prevented their frequent rotation, which promoted the accumulation of parasites in all developmental stages in the environment and quick reinfection. Feeding animals directly from the ground may also promote infection. A single deworming procedure per year appears to be insufficient.
