This study aimed to investigate the prevalence and intensity of nematode infection among slaughtered donkeys in Kaltungo, Nigeria.
A total of 72 fecal samples were examined by salt flotation and the modified McMaster fecal egg count technique to morphologically identify nematodes eggs and determine their egg per gram (EPG) outputs.
Out of a total of 72 (100%) donkeys sampled, 36 (50%) tested positive, but the prevalence of nematodes was independent of the age, sex, and breed of donkeys (p>0.05). Among the four species of nematodes identified in single and mixed infections, spp. (27.8%) and (13.9%) were the most prevalent followed by (5.6%) and spp. (5.6%). Infected donkeys had moderate overall mean EPG (801.39±611.3) with no statistical differences between age groups and sexes (p>0.05), but means of EPG were significantly higher (p<0.05) in Duni (1026.92±719.55) than Idabari (673.91±514.75). Light EPG count was recorded among 63.9% of infected donkeys, while 16.7% and 19.4% had moderate and severe infections, respectively.
The prevalence and importance of equine nematodes were discussed in connection to their epidemiology and control. Furthermore, the preponderance of light infection may suggest that donkeys in this environment developed resistance to nematode infection and are potential reservoirs for other equines.
本研究旨在调查尼日利亚卡尔通戈屠宰驴的线虫感染率和感染强度。
采用盐浮选法和改良麦克马斯特粪便虫卵计数技术对72份粪便样本进行检测,以形态学方法鉴定线虫卵并确定每克粪便中的虫卵数(EPG)。
在总共72头(100%)采样驴中,36头(50%)检测呈阳性,但线虫感染率与驴的年龄、性别和品种无关(p>0.05)。在单一和混合感染中鉴定出的四种线虫中, spp.(27.8%)和 (13.9%)最为常见,其次是 (5.6%)和 spp.(5.6%)。感染驴的总体平均EPG为中等水平(801.39±611.3),不同年龄组和性别之间无统计学差异(p>0.05),但杜尼驴(1026.92±719.55)的EPG平均值显著高于伊达巴里驴(673.91±514.75)(p<0.05)。63.9%的感染驴EPG计数较低,而分别有16.7%和19.4%的驴感染程度为中等和严重。
结合马属线虫的流行病学和防控措施,讨论了其感染率和重要性。此外,轻度感染占优势可能表明该环境中的驴对线虫感染产生了抵抗力,并且是其他马属动物的潜在宿主。
