We conducted a cross-sectional study to determine the prevalence and species of gastro-intestinal helminths and haemoparasites in 100 chickens kept under extensive management systems in Ghana, West Africa. All the examined chickens (100%) were infected with gastro-intestinal helminths; a total of 18 species were detected. The species and their prevalences were: Acuaria hamulosa (25%), Allodapa suctoria (20%), Ascaridia galli (24%), Capillaria spp. (60%), Choanotaenia infundibulum (13%), Gongylonema ingluvicola (62%), Heterakis gallinarum (31%), H. isolonche (16%), Hymenolepis spp. (66%), Raillietina cesticillus (12%), R. echinobothrida (81%), R. tetragona (59%), Strongyloides avium (2%), Subulura strongylina (10%), Tetrameres fissispina (58%), Trichostronygylus tenuis (2%), and finally one unidentified acanthocephalan (1%) and one unidentified trematode (1%). Thirty-five per cent of the chickens were infected with the haemoparasites Aegyptinella pullorum and Plasmodium juxtanucleare (prevalences 9% and 27%, respectively). Association between chicken sex and prevalences was not significant. An over-dispersed distribution was seen for most of the helminth species.
我们开展了一项横断面研究，以确定在西非加纳采用粗放式管理系统饲养的100只鸡中胃肠道蠕虫和血液寄生虫的流行情况及种类。所有接受检查的鸡（100%）均感染了胃肠道蠕虫；共检测到18种。这些种类及其流行率分别为：钩形针形线虫（25%）、吸吮全口吸虫（20%）、鸡蛔虫（24%）、毛细线虫属（60%）、漏斗带绦虫（13%）、嗉囊筒线虫（62%）、鸡异刺线虫（31%）、艾氏异刺线虫（16%）、膜壳绦虫属（66%）、有轮瑞利绦虫（12%）、棘盘瑞利绦虫（81%）、四角瑞利绦虫（59%）、禽类圆线虫（2%）、粗纹尖尾线虫（10%）、分歧四棱线虫（58%）、纤细毛圆线虫（2%），最后还有一种未鉴定的棘头虫（1%）和一种未鉴定的吸虫（1%）。35%的鸡感染了血液寄生虫拉氏埃及小体虫和近核疟原虫（流行率分别为9%和27%）。鸡的性别与流行率之间的关联不显著。大多数蠕虫种类呈现过度分散分布。
