Studies on coccidian oocysts (Apicomplexa: Eucoccidiorida).
The oocysts of the coccidia are robust structures, frequently isolated from the feces or urine of their hosts, which provide resistance to mechanical damage and allow the parasites to survive and remain infective for prolonged periods. The diagnosis of coccidiosis, species description and systematics, are all dependent upon characterization of the oocyst. Therefore, this review aimed to the pro...
متن کاملOn the status of Eimeria nieschulzi oocysts embedded in resin eleven years ago: a permanent method for preserving coccidian oocysts.
Sporulated oocysts of Eimeria nieschulzi that were fixed and mounted on glass slides in polymerized resin in 1976 are examined. Size, shape, and integrity of oocysts and sporocysts are compared to similar observations we made in 1977 and reported in 1978 (Journal of Parasitology 64: 163-164). Our conclusion is that the methods we reported on in 1978 provide one opportunity to produce permanent ...
متن کاملEffect of pine bark (Pinus radiata) extracts on sporulation of coccidian oocysts.
A series of experiments have been undertaken to determine the effect of water extracts from pine bark (Pinus radiata) on the inhibition of the sporulation of oocysts of three species of avian coccidia. Tubes containing coccidian oocysts isolated from droppings of coccidia-infected chickens were randomly assigned to 0, 250, 500 and 1000 microg/ml pine bark extract (PBE). The tubes were incubated...
متن کاملCoccidian parasites (Apicomplexa) of penguins (Pygoscelis ssp.) from Livingston Island and King George Island, the Antarctic
The results of investigations on the coccidian parasites of three species of pen− guins (Pygoscelis antarctica, P. papua and P. adeliae), nesting at Livingston and King George Island (South Shetland Islands, the Antarctic) are presented. Three coccidian para− sites: Eimeria pygosceli Golemansky, 2003, Eimeria sp. and Isospora sp. were identified in faecal samples from 360 examined birds. The to...
متن کاملDNA barcoding identifies Eimeria species and contributes to the phylogenetics of coccidian parasites (Eimeriorina, Apicomplexa, Alveolata).
Partial (∼ 780 bp) mitochondrial cytochrome c oxidase subunit I (COI) and near complete nuclear 18S rDNA (∼ 1,780 bp) sequences were directly compared to assess their relative usefulness as markers for species identification and phylogenetic analysis of coccidian parasites (phylum Apicomplexa). Fifteen new COI partial sequences were obtained using two pairs of new primers from rigorously charac...
