摘要

A line of Eimeria necatrix was selected by repeated passages of oocysts that were collected after peak oocyst production from feces or cecal contents of previously infected chickens. When compared with the parent strain, the new line of E. necatrix after 16 successive passages had the following characteristics: (1) the peak of oocyst production was delayed by 2 days; (2) the sizes of 9 endogenous development stages became larger; and (3) the reproductive capacity and the immunogenicity were both enhanced. This new line of E. necatrix may be used for the development of new coccidiosis vaccines.
