One thousand and twenty-four cattle, 550 sheep and 1,748 goats slaughtered in a rural slaughter slab during 1973 to 1975 were examined for evidence of liverfluke infections. The prevalence rate of Fasciola gigantica and Dicrocoelium hospes infections was respectively 65.4% and 56.0% in cattle, 40.8 and 13.1% in sheep and 17.6 and 5.2% in goats. Other trematodes detected were Schistosoma bovis and paramphistomes. The seasonal incidence of F. gigantica as well as of D. hospes was highest during and directly after the rainy season. The lower prevalence rate of F. gigantica, especially in the younger animals, during 1973-1974 was thought to be related to the 1973 drought. This was supported by the low prevalence rate in the long-range trade cattle which originated from drier areas. The results are discussed in relation to the climatic conditions during the survey period, as well as to the difference in epidemiology of F. gigantica and D. hospes infections in northern Nigeria.
1973年至1975年期间，对在一个农村屠宰场宰杀的1024头牛、550只绵羊和1748只山羊进行了检查，以寻找肝吸虫感染的证据。在牛中，巨片吸虫和霍氏双腔吸虫感染的患病率分别为65.4%和56.0%，在绵羊中分别为40.8%和13.1%，在山羊中分别为17.6%和5.2%。检测到的其他吸虫有牛血吸虫和同盘吸虫。巨片吸虫以及霍氏双腔吸虫的季节性发病率在雨季期间及刚结束后最高。1973 - 1974年期间巨片吸虫的患病率较低，尤其是在幼畜中，被认为与1973年的干旱有关。这一点得到了来自较干旱地区的长途贸易牛患病率较低的支持。结合调查期间的气候条件以及尼日利亚北部巨片吸虫和霍氏双腔吸虫感染的流行病学差异对结果进行了讨论。
