摘要： Ovine babesiosis, caused by genus of Babesia, is a zoonotic disease and mainly transmitted by hard ticks. It has led to enormous economic losses to the sheep industry in China. In the present study, an ELISA assay for simultaneous detection six strains of Babesia spp., including B. motasi Lintan, B. motasi Tianzhu, B. motasi Hebei, B. motasi Ningxian, Babesia sp. Xinjiang and Babesia sp. Dunhuang, was developed using Apical Membrane Antigen 1 (AMA1) as candidate diagnostic antigen. The sensitivity and specificity of the established ELISA were 97.4 % and 98.0 %, respectively. Relatively high level of specific antibodies could be detected from 12th day to 126th day after sheep experimentally infected with Babesia spp.. A small scale of field sera was investigated using the developed ELISA assay, and the average positive rate was 51.98 %. This study provides an easy to operate, cost effective and time saving approach, which is suitable for both field and experimental samples, thus it could be a useful tool in epidemiological investigations and diagnoses of ovine babesiosis.
