Abstract
Oocyst output and the reproductive potential of the four species of murine coccidia, Eimeria falciformis, E. ferrisi, E. papillata, and E. vermiformis were examined. Graded infections were produced by inoculating either 10, 102, 103, 104, or 105 sporulated oocysts to groups of mice. Oocyst production was estimated by examining all the feces passed. oocyst output was influenced by the size of the dose of oocysts. Maximum oocyst production per mouse was observed in groups of mice infected with 103 to 104 sporulated oocysts, after which, decline in oocyst output was observed despite increasing the dose of oocysts. The reproductive potential per oocyst given in each of the four species of Eimeria decreased as the dose of oocysts was increased. Mortality at rates of 60 and 40%, respectively, occurred in groups of mice infected with 105 sporulated oocysts of E. vermiformis and E. ferrisi.This publication has 0 references indexed in Scilit:
