ウガンダ・ワキソ県の一と畜場における牛での肝蛭寄生率実態調査

Bovine fasciolosis is one of the most important parasitic diseases of cattle causing mortality and production losses in various parts of Uganda. However, little information is available about its prevalence in Uganda. A cross sectional study aimed at determining the prevalence of liver flukes in cattle was conducted between June 2015 and May 2016 at an abattoir in Wakiso District, Uganda. The study was based on post-mortem inspection of livers of slaughtered animals at Wakiso abattoir. Out of 287 livers inspected, 44(15.0%)were positive for liver flukes. Risk factors such as season, breed and sex did not have significant effect on the prevalence of infections(P >0.05). However, age and body condition showed significant association with the prevalence of infections(P 0.05)。しかし、年齢及び BCS と寄生率には、相関関係が認められた(P<0.05)。つまり、年齢の高い牛及び BCSが低い牛の方が、寄生率が高いことを示していた。肝蛭の寄生数に関しては、75%が から20 虫体の間であったが、100 虫体を超える肝臓も認められた。本研究の結果は、先にウガンダのカンパラで行われた研究に比較して、肝蛭寄生率は低いものであったが、放牧地汚染及び感染個体を減らすためには、戦略的な予防治療策が必要であると思われた
