[ Method] By using indirect hemagglutination assay kits for detection of antibodies against Mycoplasma capricolum subsp, capripneumoniae ( Mecp), Mycoplasma mycoides subsp. capriclonum (Mmc) and Mycopalsam ovipneumonia ( Movi), 1 157 goat sera from Taizhou City of Jiangsu Province were detected. [ Result ] The average positive detection rate of Mccp and Mmc in infected goats was 51.85% and 39.81%, respectively; the average positive detection rate of Mccp and Mmc in non-infected goats was 10.52% and 5.84%, respectively, and the total positive detection rate of Mycoplasma infections was 16.37%. [ Conclusion ] Mycoplasma infections oc- cur commonly in Taizhou City. The prevention and control of Mycoplasma infections should be strengthened.展开更多
