| prevalence of coccidia in pigs in zimbabwe. | faecal specimens from 162 piglets, aged 1-5 months, from four farms around harare were examined for coccidia during 1989-1990. oocyst count per gram (opg) of faeces was determined by the mcmaster technique. identification of eimeria species was done after sporulation of oocysts in 2.5% potassium dichromate solution. measurements of sporulated oocysts were taken from 20 positive cases by using calibrated eye micrometer. overall incidence was 25.3% (41/162) varying between 15 and 39.5% at differen ... | 1992 | 1561754 |
| coccidia of feral swine from florida. | fecal samples from 251 free-ranging feral swine (sus scrofa) in florida were examined for coccidia. ten species of coccidia were recovered. in descending order with respect to prevalence, they were eimeria porci, e debliecki, e neodebliecki, e scarbra, e suis, e cerdonis, e polita, e perminuta, isospora suis, and e spinosa. of the swine examined, 87% were passing oocysts and 82% of the infected individuals were shedding at least 2 species of coccidia. all age classes included infected individual ... | 1982 | 7174441 |
| pcr-based differentiation of three porcine eimeria species and isospora suis. | isospora suis and eimeria are frequent coccidian parasites of pigs. the unsporulated oocysts of eimeria species and of i. suis are difficult to differentiate. therefore, a species-specific pcr was developed. pcr products were amplified from eimeria polita, eimeria porci, and eimeria scabra using primers from the conserved 18s rrna regions and were subsequently sequenced. based on variable sequence regions, primers were constructed for the differentiation of the three eimeria species and i. suis. ... | 2001 | 11163694 |
