OBJECTIVE: To investigate the spray of niclosamide ethanolamine salt on prevention of bovine schistosomiasis in the field so as to provide a technical support for the improvement of schistosomiasis control strategy.
METHODS: A total of 160 buffalo were selected as experimental objects marked by ear-mark numbers. All the buffalo were administered with praziquantel and then randomly divided into 3 groups, which were sprayed with niclosamide ethanolamine salt (500 ml per head) every 15 d (Group A), every 30 d (Group B) and an agent without niclosamide ethanolamine salt every 15 d (Group C as the control), respectively. The buffalo's droppings were collected to examine the eggs of schistosome every 30 days during the trial.
RESULTS: Ninety days after the spraying, the prevalence rates of schistosomiasis were 4.00%, 4.08%, and 24.49% in the Group A, Group B, and Group C, respectively. Compared with the control group (Group C), the decline prevalence rates of schistosomiasis were 83.67% and 83.34% in the Group A and Group B, respectively.
CONCLUSIONS: The buffalo spraying with 1% niclosamide ethanolamine salt can reduce schistosomiasis prevalence in bovine, that is this intervention has an obvious protective effect.
