An initial survey of 150 horses from Thailand for anti-Pythium insidiosum antibodies

Pythium insidiosum causes a life-threatening infection termed pythiosis in humans and other animals. The organism has been identified tropical subtropical environments worldwide. Since 1985, human increasingly reported from Thailand. Seroprevalence studies estimated that 32,000 Thai people had exposed to the pathogen. In 2018, first animal case Thailand was diagnosed horse. Here, we investigated seroprevalence of anti-P. antibodies equine population. We surveyed serum 150 horses distributed across Thailand, using three established serological tests: enzyme-linked immunosorbent assay (ELISA), immunochromatographic test (ICT), Western blot analysis. ELISA detected horses. ICT confirmed presence one ELISA-positive Based on positive out tested, population 0.7%, which is markedly higher than (0.07%), but much lower Brazilian (11.1%). suggests incidence humans. antibody surveillance by our group undertaken promote better understanding epidemiology host susceptibility
