The present investigation aimed to examine the prevalence of Chlamydia infection in pigs in Guangdong Province, Southern China. Between March 2008 and May 2009, a total of 1,017 serum samples were collected from 15 intensive farms, which are distributed in 12 administrative cities of Guangdong Province and assayed for Chlamydia antibodies by Indirect Hemagglutination Assay (IHA). The results showed that almost all of the investigated farms showed seroprevalence (93.33%, 14/15). The average seroprevalence of pigs with Chlamydia antibodies was 30.78% (ranged between 0-88%) with breeding boars having the highest prevalence (63.38%, 45/71), which was followed by breeding sows (41.10%, 60/146) and fattening pigs (36.25%, 29/80). These results indicated that prevalence of Chlamydia infection in pigs from intensive farms in Southern China is high, therefore integrated and improved control strategies and measures should be implemented to prevent and control Chlamydia infection in pigs.
