Seroprevalence of Trypanosoma evansi Infection in Water Buffaloes from the Mountainous Region of North Vietnam and Effectiveness of Trypanocidal Drug Treatment

[摘要] References(16)Cited-By(1)Water buffalo (WB) is an important domestic animal in Vietnam. This study utilized a card agglutination test to investigate seroprevalence of surra in WB population. Sera were collected from 585 WB from 4 different regions in Cao Bang and Thai Nguyen Provinces. Among them, 131 samples (22.4%) were positive for surra. The highest prevalence (24.6%) was found among 3 to 5 years old WB. Buffaloes less than 3 years old had the lowest prevalence (15.6%). Among 27 abortion cases, 9 WB (33.3%) were surra positive. For treatment of surra, Berenil® demonstrated a 100% cure rate, while that of Trypamidium® was only 40%. Our findings suggest that the current control strategy has not succeeded in reducing prevalence of surra in Vietnam.
