摘要
在从尼日利亚三角洲州 Ase 的蛙 Amnirana galamensis 的直肠中提取到一种臂脂吸虫的 metacercariae 之后,我们对当地的陆地蜗牛进行了调查,以确定它们在寄生虫生命周期中的作用。在调查的四种产自 Ase 的田螺(Limicolaria aurora、Archachatina marginata、A. papyracea 和 Thapsia oscitans)和一种产自 Tombia(巴耶尔萨州)的 Limicolaria sp.只有 L. aurora 和 Limicolaria sp.携带蛔虫孢子囊,因此被推测为寄生虫的第一中间宿主。从纤毛虫属(Limicolaria)和弓形虫属(Archachatina)中发现了蛔虫(Metacercariae),因此可作为第二中间宿主。从 T. oscitans 身上没有发现幼虫 brachylaimids。在 14 天大的家鸡体内培养了来自 L. aurora 和 A. papyracea 的 metacercariae。从感染后 7、14、21 和 28 天的实验宿主体内回收的寄生虫显示,寄生虫逐渐发育,在感染后第 28 天达到完全成熟。从实验鸟类以及从阿塞(Ase)和托比亚(Tombia)购买的散养鸡中回收的成虫表明,感染这些鸟类的胸棘鲷是Postharmostomum ntowi,这是一种以前在加纳家鸡中报道过的寄生虫。有必要调查这种寄生虫在尼日利亚的寄主范围,因为已知加纳的几内亚鸡也感染了这种颤抖虫。
Observations on the biology of Postharmostomum ntowi Hodasi, 1967 (Trematoda: Brachylaimidae) based on intermediate and definitive hosts found in Nigeria.
Following the recovery of the metacercariae of a brachylaimid trematode from the rectum of the frog Amnirana galamensis from Ase in Delta State, Nigeria, we investigated the land snails in the locality to establish their roles in the life cycle of the parasite. Of the four land snails investigated from Ase (Limicolaria aurora, Archachatina marginata, A. papyracea, and Thapsia oscitans), and a Limicolaria sp. from Tombia (Bayelsa State), four harboured larval stages of the bracylaimid. Only L. aurora and the Limicolaria sp. harboured cercariogenous sporocysts and are therefore presumed to serve as the first intermediate hosts of the parasite. Metacercariae were recovered from the Limicolaria spp. and the Archachatina spp. and so serve as the second intermediate hosts. No larval brachylaimids were recovered from T. oscitans. Metacercariae from L. aurora and A. papyracea were cultured in vivo in 14 days old chicks of Gallus gallus domesticus. Parasites recovered from the experimental hosts 7, 14, 21 and 28 days post-infection, showed progressive development of the parasite with the full maturity attained by the 28th day post-infection. Adult parasites recovered from the experimental birds and from free range chicken purchased from Ase and Tombia showed that the brachylaimid infecting these birds was Postharmostomum ntowi, a parasite previously reported in domestic chicken in Ghana. There is need to investigate the host range of the parasite in Nigeria as this trematode is also known to infect the Guinea fowl in Ghana.
期刊介绍:
Helminthologia (HELMIN), published continuously since 1959, is the only journal in Europe that encompasses the individual and collaborative efforts of scientists working on a different topics of human, veterinary and plant helminthology. The journal responsibility is to enrich the theoretical and practical knowledge in very specific areas and thus contribute to the advancements in human and veterinary medicine and agronomy. Taking the advantage of comprehensive and multidisciplinary approaches journal still maintains its original spirit and is principal source of fresh scientific information regarding helminths, endoparasites and plant parasites. Addressing the most up-to date topics journal gained rightful and exceptional place next to the other high-quality scientific journals publishing in its field.
