anticoccidial drugs for preventive therapy in intensively reared pheasants.a range of anticoccidial drugs was tested in young pheasants inoculated with three species of eimeria. eimeria colchici, the most pathogenic species, was completely controlled by clopidol/methyl benzoquate and robenidine hydrochloride with the elimination of oocyst production. clopidol and arprinocid gave good protection with reduced oocyst output and clopidol also adversely affected oocyst sporulation. halofuginone and monensin were less effective. amprolium hydrochloride/sulphaquinoxaline/etho ...19817336544
course of the endogenous developmental phase of selected eimeria species in pheasants.the localization and duration of developmental stages of eimeria colchici and eimeria duodenalis were studied histologically. the prepatent period of the most pathogenic species from the caeca of pheasants--eimeria colchici--was 6 days. the patent period began on the 7th day and finished on the 11th day post-infection with the maximum production of oocysts on days 8-9. in the case of eimeria duodenalis the prepatent period was shorter--4 days, and the duration of the patent period was 3-4 days w ...19989763319
effect of ozone treatment on eimeria colchici oocysts.the effect of ozone on the inhibition of the sporulation of eimeria colchici oocysts in vitro was examined. lower sporulation ratios were found to correspond directly to longer ozone exposure time. in pheasants, phasianus colchicus, orally inoculated with ozone-treated oocysts, lower mortality and lower oocysts per gram of feces were observed as compared with birds given untreated oocysts. thus, treatment of e. colchici oocysts with ozone alone was observed to partially inhibit the growth and in ...200212053957
an unusual case of coccidiosis in laboratory-reared pheasants resulting from a breach in biosecurity.an outbreak of coccidiosis in laboratory-reared chinese ring-necked pheasants (phasianus colchicus) resulted in high morbidity and moderate mortality. the outbreak was associated with a breach in biosecurity caused by the cleaning of a sewer line with a mechanical device, resulting in extensive splattering of fecal material throughout the "clean room" where birds were held prior to use in coccidiosis experiments. mortality and morbidity in the affected birds were seen exactly 5 days after the in ...201020945799
coccidia of the pheasant.the author reviews the literature on the coccidia of the pheasant. ten species are described, of which three are associated with disease in the united kingdom, eimeria colchici, e. duodenalis and e. phasiani.1976795759

immunization against coccidiosis in pheasants with low-dose live sporulated oocysts of eimeria colchici.low-dose immunization of pheasants with live eimeria colchici oocysts was observed to be effective against massive challenge infection. fourteen-day-old pheasants, in groups of 28, were orally inoculated with about 100, 250, 500, 1000 and 2000 sporulated oocysts. these birds were then challenged homologously with about 120 000 sporulated oocysts 18 days after the immunization. during the 12-day observation period after the challenge infection, over 92% of the immunized pheasants were still alive ...200119184914
cellular immunological responses of pheasant during endogenous development of eimeria colchici.we examined the time course and histological localisation of the developmental stages of eimeria colchici. the prepatent period in the caeca of pheasants was 6 days. the patent period began on day 7 post-infection (p.i.) and ended on day 11 p.i. with peak production of oocysts on days 8-9. the peripheral blood lymphocytes of pheasant chicks showed a significant increase in proliferation to e. colchici antigen from day 5 p.i., with peak on day 14 p.i. the metabolic activity (respiratory burst) of ...200010882904
use of amprolium for the control of coccidiosis in pheasants.amprolium administered in feed during the first 4 weeks of life at a level of 0.0175% protected pheasants against three major pathogenic species of coccidia (eimeria colchici, e. duodenalis, and e. phasiani) when they were exposed at 2 weeks of age. the difference was significant when mortalities were compared between medicated infected (3%) and unmedicated infected (35%) pheasants. the manufacturer's proposed level (0.0175%) and twice the proposed level (0.0350%) of amprolium had no significant ...19846487190
