A serological surveillance study was conducted between March and June 2006 in the southern provinces of Cambodia to determine the prevalence and distribution of foot-and-mouth disease. Cattle and buffalo originating from eight provinces and 69 villages were sampled. The results revealed that the village level prevalence of foot-and-mouth disease (FMD) in the southern provinces of Cambodia was 87% with an overall individual animal prevalence of 30%. Three serotypes: O, A and Asia 1 were detected in this region with a prevalence of 28.5, 9.5 and 9.3%, respectively. However, as the antibody level to FMDV serotypes A and Asia 1 were generally low, it is likely that serotype O is responsible for most of the recent outbreaks of FMD in Cambodia. Seropositive animals were older than seronegative animals, especially with serotype O.
2006年3月至6月间，在柬埔寨南部省份开展了一项血清学监测研究，以确定口蹄疫的流行率和分布情况。对来自8个省份69个村庄的牛和水牛进行了采样。结果显示，柬埔寨南部省份口蹄疫的村级流行率为87%，个体动物总体流行率为30%。在该地区检测到三种血清型：O型、A型和亚洲1型，流行率分别为28.5%、9.5%和9.3%。然而，由于针对A型和亚洲1型口蹄疫病毒血清型的抗体水平普遍较低，O型血清型很可能是柬埔寨近期大多数口蹄疫疫情的罪魁祸首。血清阳性动物比血清阴性动物年龄大，尤其是O型血清型。
