摘要: The Eimeria tenella Yulin strain (EtYL), which is sensitive to most anti-coccidial drugs, was isolated in the Yulin area of Guangxi, China. Then, Eimeria tenella Yulin precocious line (pEtYL), a precocious line with a prepatent period of 108 h, was obtained through early selection. The biological characteristics of pEtYL, including its morphology, purity, oocyst excretion curve, reproductive capacity, pathogenicity, immunogenicity, and preservation time, were comprehensively analyzed. The results showed that the isolated precocious line of E. tenella exhibited high purity, relatively weak pathogenicity, and good immunogenicity and can be used as a live vaccine line for chicken coccidiosis.
