| 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 |
| gene expression in rabbit appendices infected with eimeria coecicola. | eimeria coecicola causes intestinal coccidiosis in rabbits and, thereby, enormous economic losses in rabbit farms. here, we investigate the final target site of e. coecicola, the appendix of rabbits, at the level of gene expression. rabbits, orally infected with e. coecicola, begin to shed parasitic oocysts with their feces on day 5 p.i., and approximately 1.1 million oocysts are maximally shedded on day 7 p.i. at maximal shedding, the appendix has increased in size by about 2-3-folds and reveal ... | 2011 | 22154972 |
| the pathogenicity of rabbit coccidium eimeria coecicola cheissin, 1947. | the pathogenicity of eimeria coecicola for rabbits has been demonstrated in our experiments. the animals suffered from prolonged affection of appendix lasting at least 20 days. pathological changes appeared with the development of merogony since day 4 post infection (dpi) and were characterized by an inflammatory infiltration and abundant pyogenic component in lamina propria, swelling and coalescence of upper parts of appendix mucosa above atrophied domes, where spaces filled with stagnating inf ... | 1989 | 2488044 |
| eimeria coecicola: spleen response of oryctolagus cuniculus. | the apicomplexan protozoon eimeria coecicola is an infectious agent of intestinal coccidiosis in rabbits, causing severe injuries in the appendix as the final target, but also in the liver though not being a target. here, we investigated the effect of e. coecicola on the spleen of the rabbit oryctolagus cuniculus with respect to structure and gene expression using 2-color agilent whole rabbit genome oligo-microarray technology in combination with quantitative pcr. at maximal fecal output of e. c ... | 2013 | 23206958 |
| induced metabolic disturbance and growth depression in rabbits infected with eimeria coecicola. | eimeria coecicola causes intestinal coccidiosis in rabbits and, thereby, enormous economic losses in rabbit farms. this study aimed to investigate the effect of intestinal coccidial infection, e. coecicola on metabolic status and growth of rabbits. animals were allocated into two groups with eight rabbits each; one group was orally inoculated with saline and served as control while the other group was orally inoculated with 5 × 10(4) sporulated oocysts. on day 7 postinfection, fecal expulsion of ... | 2013 | 23749092 |
| liver response of rabbits to eimeria coecicola infections. | intestinal coccidiosis of rabbits induced by e. coecicola causes enormous economic losses in rabbit farms. here, we investigate the effect of e. coecicola on the liver of the rabbit oryctolagus cuniculus. on day 7 p.i., fecal expulsion of e. coecicola oocysts is maximal and rabbits have lost approximately 25% of their weight. the liver, though not targeted by parasites, exhibits several signs of moderate inflammations, i.e., inflammatory cellular infiltrations around the central vein, dilatated ... | 2011 | 21822680 |
| coccidiosis of domestic rabbit (oryctolagus cuniculus) in egypt: light microscopic study. | in the present study, the incidence and prevalence of coccidian infection among domestic rabbits in egypt were investigated. severe overall prevalence reaching 70% (70/100) was recorded. eight species of eimeria were detected. mixed infection with three different species occurred most frequently. eimeria intestinalis and eimeria coecicola were generally the most predominant species. the complete life cycle of e. intestinalis was investigated. this study is the first to report coccidia in domesti ... | 2011 | 21647671 |
| eimeria species in wild rabbits (oryctolagus cuniculus) in fars province, iran. | this investigation was accomplished during february to november 2008. a total of 71 wild rabbits (oryctolagus cuniculus) of about 5 to 12 months age were collected alive from different parts of fars province, south of iran. faecal sampling was carried out directly from recti and the oocysts were isolated using sedimentation and floatation techniques and the sporulated oocyst were identified based on morphological and biological characteristics. all the rabbits were apparently healthy and showed ... | 2010 | 21399588 |
| 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 |
| invasion of the intestinal tract by sporozoites of eimeria coecicola and eimeria intestinalis in naive and immune rabbits. | naive and immune specific-pathogen-free rabbits were inoculated in the duodenum with sporocysts of eimeria coecicola or eimeria intestinalis. samples were taken from the following tissues: duodenum (site of penetration of sporozoites), ileum (specific target site of the endogenous development of e. intestinalis), vermiform appendix (target site of e. coecicola) and two extraintestinal sites, mesenteric lymph nodes (mlns), and spleen. the presence of sporozoites was checked by immunohistochemistr ... | 2006 | 16362337 |
| tissues and cells involved in the invasion of the rabbit intestinal tract by sporozoites of eimeria coecicola. | this study was designed to identify an extra-intestinal route of migration of eimeria coecicola sporozoites and the types of cell harbouring the parasite during the invasion of the intestine. the presence of e. coecicola in blood, spleen and mesenteric lymph nodes of infected donor rabbits was demonstrated by immunohistology on donor organs and measurement of oocyst excretion by coccidia-free recipient rabbits injected with whole-cell suspensions prepared from donor tissues. two types of donor l ... | 2001 | 11206118 |
| eimeria coecicola cheissin 1947: endogenous development in gut-associated lymphoid tissue. | coccidia-free rabbits were inoculated with different doses of a pure strain of eimeria coecicola and samples of gut were taken at 80, 96, 112, 128, 144, and 160 h postinoculation. the use of a very low infective dose (2-20 oocysts) was sufficient to study the last merogony. the number of merozoites in meronts increased when the infective dose decreased. only the first merogony of this coccidium in lymphocytes or m-cells of gut-associated lymphoid tissue (galt) has previously been described. thre ... | 1996 | 8740551 |
| migration of sporozoites and merogony of eimeria coecicola in gut-associated lymphoid tissue. | the invasive phase of eimeria coecicola was studied during the first 80 h postinoculation (p.i.). using a method that synchronized the life cycle, sporozoites were observed in the duodenum and the jejunum until 32 h p.i. they were seen first in the villous epithelial cells or in host cells resembling intraepithelial lymphocytes (iel). later they were observed in iel in the lamina propria. after 48 h p.i., no coccidian stage was identifiable in the mucosa of the small intestine but sporozoites ap ... | 1993 | 8278342 |
| life cycle of eimeria coecicola cheissin, 1947. | life cycle of eimeria coecicola was studied in experimentally infected rabbits by light microscopy and by transmission and scanning electron microscopy. first and second generation meronts developed in the vermiform appendix; third and fourth generation meronts were located in the epithelium of the ileum. gametogony developed again in the vermiform appendix. the prepatent period was 9 days. new data were obtained by the study of asexual reproduction. first generation meronts were first observed ... | 1989 | 2767560 |
