| the rabbit coccidium eimeria piriformis: selection of a precocious line and life-cycle study. | specific pathogen-free (spf) rabbits were inoculated with oocysts of an original strain (os) of eimeria piriformis and the first newly developed oocysts recovered from the intestine were used for infection of other rabbits. the prepatent period (pp) was shortened after 12 passages from 194 to 170 hours and remained stable after 5 passages without any selection pressure. oocysts of the precocious line (pl) exhibited peculiar morphology. besides refractile bodies (rb) within sporozoites, one huge ... | 2006 | 16473468 |
| effect of subcutaneously administered diclazuril on the output of eimeria species oocysts by experimentally infected rabbits. | the effect of subcutaneously injected diclazuril on the output of eimeria species oocysts was studied in experimentally infected rabbits. diclazuril was administered either prophylactically at 0.5, 1 or 2 mg/kg bodyweight two days before each rabbit was inoculated with 20,000 oocysts of a mixed-species field isolate of eimeria or therapeutically at 1, 2 or 4 mg/kg bodyweight five days after they were inoculated. the prophylactic treatments significantly reduced (p<0.05) the output of oocysts in ... | 2008 | 18245747 |
| effect of chromium compounds on sporulation of eimeria piriformis oocysts. | freshly defecated unsporulated oocysts of eimeria piriformis from rabbit were treated with various concentrations (1%, 2.5%, 5%, and 10%) of chromium compounds, potassium dichromate, potassium chromate, chromium oxide and chromium nitrate, to examine their effect on sporulation. the sporulation time of oocysts treated with 1 to 10% k(2)cr(2)o(7) was 28 h. however, much longer sporulation times of about 60 h were required for oocysts treated with 2.5% cro(3) and cr(no(3))(3). moreover, for oocyst ... | 2008 | 18256522 |
| prevalence, infectivity and oocyst sporulation time of rabbit-coccidia in taiwan. | prevalence of eimeria species parasitizing rabbits (oryctolagus cuniculus) in taiwan were investigated. six eimeria species, namely: eimeria media (prevalence, 158/642; 24.6%), eimeria magna (101/642; 15.7%), eimeria perforans (58/642; 9.0%), eimeria coecicola (46/642; 7.2%), eimeria piriformis (16/642; 2.5%), and eimeria exigua (9/642; 1.4%) were observed. the overall prevalence of these coccidial infections in rabbits from pet shops and farms was 46.2% and 41.7%, respectively. concurrent infec ... | 2010 | 21399582 |
| fecal occult blood manifestation of intestinal eimeria spp. infection in rabbit. | the relationship between oocysts production and fecal occult blood manifestation was studied in rabbits experimentally infected with a single species of eimeria. pure single eimeria species infection in non-infected rabbits for 6 species of eimeria, namely: eimeria media, eimeria magna, eimeria perforans, eimeria coecicola, eimeria piriformis, and eimeria exigua were produced using a single oocyst. fecal samples from these single eimeria species infected rabbits were collected daily from day 1 t ... | 2009 | 19233566 |
