Helminth infections are one of the greatest causes of productive and reproductive loss in animals and man, and in some cases, it results in heavy mortalities. This study was conducted to determine the prevalence, species diversity, patterns of infections and risk factors associated with helminth infections of cattle in Ilorin, Nigeria.
A total of 478 fecal samples were collected from abattoirs and cattle farms over a year period (March, 2018-February, 2019). Fecal samples were visually examined then observed using simple flotation and formalin-ethyl acetate sedimentation techniques. Eggs and worms were identified according to standard procedures. The packed cell volume was determined using the hematocrit centrifugation technique.
A total of 79.92% of the cattle examined were found positive with one or more helminth species. Eighteen helminth species (cutting across all classes of helminths) were detected, with (60.46%), spp. (46.44%), (42.05%), (28.87%), spp. (24.27%), (21.97%), (12.13%), and (10.67%) been the most prevalent. Helminth infection was detected all through the year with the least prevalence recorded in February (55.00%). About 61% of the examined cattle harbored double/multiple helminth species. There was a significant difference between breed, sex, physiological status, and season with the prevalence rate of helminth infections (p<0.05).
Our investigation demonstrated high prevalence and wide diversity of helminth species, which suggests that helminth infections are of great concern among cattle in Ilorin and Nigeria in general. There is a need for a radical veterinary intervention to curb the menace so as to have an economically robust cattle industry in Nigeria.
蠕虫感染是导致动物和人类生产及繁殖损失的主要原因之一，在某些情况下，还会导致高死亡率。本研究旨在确定尼日利亚伊洛林地区牛蠕虫感染的流行率、物种多样性、感染模式及相关风险因素。
在一年时间内（2018年3月至2019年2月），从屠宰场和养牛场共采集了478份粪便样本。对粪便样本先进行肉眼检查，然后采用简单漂浮法和福尔马林-乙酸乙酯沉淀法进行观察。根据标准程序鉴定虫卵和虫体。采用血细胞比容离心技术测定红细胞压积。
共检测出79.92%的受检牛感染了一种或多种蠕虫。检测到18种蠕虫（涵盖所有蠕虫类别），其中（60.46%）、 spp.（46.44%）、（42.05%）、（28.87%）、 spp.（24.27%）、（21.97%）、（12.13%）和（10.67%）最为常见。全年均检测到蠕虫感染，2月份的感染率最低（55.00%）。约61%的受检牛感染了两种或多种蠕虫。蠕虫感染的流行率在品种、性别、生理状态和季节之间存在显著差异（p<0.05）。
我们的调查表明蠕虫种类的流行率高且多样性广泛，这表明蠕虫感染在伊洛林乃至整个尼日利亚的牛群中是一个令人高度关注的问题。有必要采取彻底的兽医干预措施来遏制这一威胁，以便在尼日利亚建立一个经济稳健的养牛业。
