Brucellosis and Q fever impart high morbidity in humans and economic losses among livestock worldwide. However their prevalence is still not fully known in Thailand. We conducted a sero-survey of brucellosis and Q fever in beef, dairy cattle, goat, and sheep herds from Thai communities at the border with Cambodia, a cross-border trading center. Serum samples were tested for brucellosis and Q fever by antibody-based tests at the National Institute of Animal Health, Thailand. We surveyed a total of 520 individuals from 143 herds. Brucellosis herd-level seroprevalence for beef cattle and small ruminants (goats and sheep) was 2.6% (3/117) and 13.3% (2/15) respectively. Q fever herd-level seroprevalence for beef cattle, dairy cattle, and small ruminants was 4.3% (5/117), 27.3% (3/11) and 33.3% (5/15) respectively. This study identified a significant burden of brucellosis and Q fever among small ruminants and dairy cattle at the Thai-Cambodian border.
