Reclassification of Eimeria pogonae Walden (2009) as Choleoeimeria pogonae comb. nov. (Apicomplexa: Eimeriidae).

The presented paper provides a reclassification of Eimeria pogonae from Pogona vitticeps into the correct genus Choleoeimeria. A description of exogenous and endogenous stages of biliary coccidium is given. Sporulation of the oocysts was endogenous. The mature oocysts contained four sporocysts each with two sporozoites. Oocysts were ellipsoidal in shape, with average length/width ratio 1.7 and measured 28.4 (SD1.5) × 16.8 (SD 1.5). The micropyle, residuum, and polar granules were absent from the sporulated oocysts. Ovoidal in shape, sporosysts without Steida bodies contained residuum and two elongated and boat-shaped sporozoites. The endogenous stages of the coccidia were located mainly in the epithelium of bile ducts; however, single-epithelium cells of the gallbladder were also infected.

Occurrence of gastrointestinal parasites in slaughter rabbits.

The aim of the study was to determine the occurrence of gastrointestinal parasites in slaughter rabbits managed in small scale farms and under industrial farming system. The research material included intestines and livers of rabbits slaughtered between years 2007 and 2011. The rabbit carcasses submitted to parasitological examination had passed the sanitary veterinary inspection as fit for human consumption. The samples were collected in spring and autumn seasons. The studies showed no effect of a rabbit farming system, season of the year, or differences in an invasion type in each year. The parasitological test recognized exclusively mixed infestation diagnosed in 79.56% of the studied animals. Parasitological evaluation of the rabbit internal organs identified the invasions of coccidia (78.83%), nematoda (16.42%), cestoda (0.72%), and cysticerci Cysticercus pisiformis (4.74%). Coccidian invasions found in intestines were dominant, and their prevalence reached 56.48%, while the hepatic coccidian extensity was markedly lower, i.e., 3.34% of the examined rabbits. Invasions were characterized by low intensity. The studies recognized invasions of nematoda (Obeliscoides cuniculi, Graphidium strigosum, Trichostrongylus sp., Strongyloides sp., Passalurus ambiguus, Trichuris leporis), cestoda (Mosgovoyia pectinata), and cysticerci C. pisiformis.

Comparison of the sensitivity of coprological methods in detecting Anoplocephala perfoliata invasions.

The autopsy of 487 slaughter horses revealed the presence of Anoplocephala perfoliata in 36 animals. The invasions varied in the intensity (3 to 2,069 tapeworms) and in the level of tapeworms' proglottid maturity. Twenty nine horses were found to contain tapeworms with gravid proglottid. Fecal samples collected from the rectum were tested using following techniques: flotation with solution-saturated NaCl, decantation, McMaster's, and modified sedimentation-flotation methods (50 g feces samples, flotation solution-saturated NaCl and sucrose, specific gravity 1.25 g/ml). The number of A. perfoliata positive fecal samples was significantly higher using the sedimentation-flotation methods 21 (58.33%) than flotation 6 (16.66%), decantation 3 (8.33%), and McMaster's 1 (2.77%) techniques. The sensitivities of the coprological methods during the patent period were 20.69, 10.34, 3.45, and 72.41% for the flotation, decantation, McMaster's, and sedimentation-flotation method, respectively. Sedimentation-flotation techniques proved to be more sensitive than other one. The lowest intensity of invasion possible to detect using this method was nine tapeworms with gravid proglottid.
