Abstract: The objective of the present investigation was to examine the seroprevalence of Actinobacillus Pleuropneumoniae (APP) in Tibetan pigs in Tibet, China by using an Indirect Hemagglutination Assay (IHA). Serum samples were collected from 332 Tibetan pigs in Nyingchi, Tibet, China between April and December 2010 and were examined for APP antibodies using a commercially available IHA kit. A total of 185 (55.72%) Tibetan pigs were examined seropositive for APP antibodies. The prevalence ranged from 42.68-71.11%, varying in different age groups except breeding boars and sows with higher prevalence in piglets and lower prevalence in slaughter pigs but the difference was not statistically significant (p>0.05). The investigation also showed that the prevalence of APP in female animals was 54.70 and 59.72% in male animals. The results indicated a widespread exposure to APP among Tibetan pigs in Tibet, China. This is the first report documenting the infection of APP in Tibetan pigs in Tibet, China.
