Abstract

OBJECTIVE

The aim of this study was to investigate the morphological features of acanthocephalans isolated from (Bloch, 1793).

METHODS

Fishes collected alive from fish farms in Nadia District of West Bengal (India) were dissected for collection of acanthocephalans. Parasites isolated from intestine were fixed in formalin-aceto-alcohol and finally preserved in 70% ethanol for light microscopic studies and in 2.5% glutaraldehyde for scanning electron microscopy.

RESULTS

The morphological characteristics of adult acanthocephalans were found to be similar to the original descriptions describing the basic characters of proboscis hooks, the spines of the collar and trunk region, and cement gland nuclei. New taxonomic characters were identified for the first time by scanning electron microscopy.

CONCLUSION

The acanthocephalan Agarwal 1958 was described as an important parasite infecting fishes. The prevalence of the parasite was 23% and its adult stage was observed.

摘要

目的

本研究旨在调查从（布洛赫，1793年）分离出的棘头虫的形态特征。

方法

从印度西孟加拉邦纳迪亚区养鱼场活体采集的鱼类进行解剖，以收集棘头虫。从肠道分离出的寄生虫用福尔马林 - 醋酸酒精固定，最后保存在70%乙醇中用于光学显微镜研究，保存在2.5%戊二醛中用于扫描电子显微镜研究。

结果

发现成年棘头虫的形态特征与描述吻钩、颈环和躯干区域的棘以及粘腺核基本特征的原始描述相似。通过扫描电子显微镜首次鉴定出新的分类特征。

结论

1958年的棘头虫 阿加瓦尔被描述为一种感染鱼类的重要寄生虫。该寄生虫的感染率为23%，并观察到了其成虫阶段。
