海晏县沼泽草场牛羊放牧情况及同盘吸虫感染调查

为了解海晏县沼泽草场放牧牛羊及同盘吸虫感染等情况而进行了本调查，结果为：沼泽草场放牧户占到全县总放牧户数的9.27%,放牧牛羊分别占到全县牛羊总数的10.93%和12.65%。77.78%的沼泽草场放牧户牛羊感染同盘吸虫，而牛群和羊群同盘吸虫感染率分别达到了59.26%和48.15%;牛羊群体混合感染率40.74%;牛羊个体同盘吸虫感染率分别为14.83%和17.04%。结果还表明专业技术人员等对同盘吸虫病了解不足，区域间感染率差别较大，牛羊感染率有上升的趋势，证明现在使用的驱除药物对同盘吸虫虫卵阳性率降低很不理想，今后对本病的预防知识普及宣传及技术培训、驱除药物研制和筛选、湿地椎实螺的防治十分迫切。
