Abstract:In order to investigated the prevalence of Chlamydia from sheep and goat in parts of China, we collected 742 blood samples from eight provinces (zone) by using the Chlamydia indirect hemagglutination test (IHA) antibody testing. The overall positive rate of sheep chlamydial antibody was 46.09%(342/742) in this eight provinces (zones), including Hubei 60.00%, Anhui 42.86%, Shandong 52.75%, Xinjiang 40.13%, Jilin 51.91%, Sichuan 30.56%, Ningxia 67.74%, and Gansu 90%. Results showed that sheep Chlamydia spreads widely in our country, producing a serious threat to sheep husbandry. By comparing the serological test data of this experiment with the past ones, an upward trend is discovered year by year in infection rate of sheep Chlamydia. Blood samples of this test collected were from 567 sheep and 175 goats, and the seroprevalence in sheep and goats was 47.27% and 42.28%, respectively. The result showed that infection rate of sheep was higher than that in goats.
