Abstract

Purpose

The influence of two key factors, host length and infection site, on the host-parasite interaction in Ompok bimaculatus (Butter catfish) from Mukutmanipur Dam Lake, were investigated.

Methods

Present study involved 192 specimens of Ompok bimaculatus with varying body lengths, subjected to diverse statistical analyses. One-way analysis of variance (ANOVA) was performed for the parasite numbers for three groups (cestode, nematode and trematode). Subsequently, we conducted one-way permutational multivariate analysis of variance (PERMANOVA) followed by pairwise test to assess parasite numbers across three body sites (intestine, mesentery, and bodycavity), employing the Bray-Curtis index. Additionally, Principal Coordinate Analysis (PCoA) for the same dataset was performed using the same index. Linear regression analysis was performed for the fish length-cestode number, fish length-nematode number, fish length-trematode number and fish length-total parasite number.

Results

One-way ANOVA revealed no significant differences in parasite numbers among the three endo-helminth groups (cestode, nematode, and trematode). The results of PERMANOVA revealed significant differences in parasite numbers across the three body sites of the host fishes (groups) (F = 9.41, p = 0.0001). Pairwise tests further demonstrated significant differences between the intestine-mesentery, intestine-body-cavity, and mesentery-body-cavity. Additionally, Principal Coordinate Analysis (PCoA) unveiled a significant relationship between infection site and parasite number. However, linear regression analysis examining the relationship between fish length and parasite abundance indicated no significant associations.

Conclusions

Through a detailed exploration of the statistical analyses, we provide insights into the host-parasite interaction, elucidating both established knowledge and novel findings in fish parasitology.

揭开生物之谜：寄主长度和感染部位对双尾鳕寄生虫数量的影响。

目的：研究了宿主体长和感染部位这两个关键因素对来自穆库特马尼普尔大坝湖的黄颡鱼（Ompok bimaculatus）宿主与寄生虫相互作用的影响：本研究涉及 192 条不同体长的 Ompok bimaculatus 标本，并进行了多种统计分析。对三组（绦虫、线虫和吸虫）的寄生虫数量进行了单因素方差分析（ANOVA）。随后，我们采用 Bray-Curtis 指数对三个身体部位（肠道、肠系膜和体腔）的寄生虫数量进行了单向包络多变量方差分析（PERMANOVA）和配对检验。此外，还使用相同的指数对同一数据集进行了主坐标分析（PCoA）。对鱼体长度-绦虫数量、鱼体长度-线虫数量、鱼体长度-线虫数量和鱼体长度-寄生虫总数进行了线性回归分析：结果：单因素方差分析显示，三组内螺旋体（绦虫、线虫和颤虫）之间的寄生虫数量无显著差异。PERMANOVA 结果显示寄生虫数量在宿主鱼类的三个身体部位（组别）之间存在显著差异（F = 9.41，p = 0.0001）。配对检验进一步表明，肠-肠腔、肠-体腔和肠-体腔之间存在显著差异。此外，主坐标分析（PCoA）揭示了感染部位与寄生虫数量之间的显著关系。然而，研究鱼体长度与寄生虫数量之间关系的线性回归分析表明，两者之间并无显著关联：通过对统计分析的详细探讨，我们深入了解了宿主与寄生虫之间的相互作用，阐明了鱼类寄生虫学的既有知识和新发现。

期刊介绍： Acta Parasitologica is an international journal covering the latest advances in the subject. Acta Parasitologica publishes original papers on all aspects of parasitology and host-parasite relationships, including the latest discoveries in biochemical and molecular biology of parasites, their physiology, morphology, taxonomy and ecology, as well as original research papers on immunology, pathology, and epidemiology of parasitic diseases in the context of medical, veterinary and biological sciences. The journal also publishes short research notes, invited review articles, book reviews. The journal was founded in 1953 as "Acta Parasitologica Polonica" by the Polish Parasitological Society and since 1954 has been published by W. Stefanski Institute of Parasitology of the Polish Academy of Sciences in Warsaw. Since 1992 in has appeared as Acta Parasitologica in four issues per year.
