摘要

鲶鱼是喀麦隆养殖的一种重要淡水鱼,以满足对鱼类产品日益增长的需求。尽管有相当大的增长潜力,但人们担心在水产养殖系统中出现对鱼类和人类都有致病性的细菌。对鲶鱼的微生物群及其栖息地的研究在很大程度上仍未被探索。鉴于了解水产养殖系统内的微生物组成对确保食品安全和保护公众健康至关重要,本研究旨在通过使用16S rRNA基因扩增子测序对喀麦隆鲶鱼鳃、肠和池塘水环境的细菌群进行调查,获得重要的初步数据。结果显示细菌群落多样(30门,678属,1056种),其中梭杆菌门,拟杆菌门,变形菌门,厚壁菌门和Verrucomicrobia共占观察到的细菌群落的93%以上。值得注意的是,在鲶鱼的鳃(49.98%)和肠(65.3%)中,Fusobacteria是优势门,而在池塘水环境中,Proteobacteria占优势门(40.24%)。3种样品均以鲸杆菌属细菌为主(鳃占49.93%;肠子,65.19%;池水占23.85%)。此外,本研究还发现了许多细菌属,包括潜在的鱼类病原体,如爱德华氏菌、气单胞菌、Plesiomonas和黄杆菌,以及人类肠道细菌,如梭状芽胞菌和拟杆菌。潜在致病性和益生菌共存的情况强调了淡水鱼养殖中的生态复杂动态,并强调了全面的微生物管理策略的必要性。这项研究提供了对喀麦隆水产养殖细菌景观的见解,揭示了鲶鱼养殖的潜在风险和收益。

Bacterial Diversity in Aquacultured African Catfish and Source Pond Water in Buea, Cameroon.

The catfish is a prominent freshwater fish species farmed in Cameroon to meet the escalating demand for fish products. Despite considerable growth potential, there are concerns about the occurrence of bacteria pathogenic to both fish and humans within aquaculture systems. Research on the microbiome of catfish and their habitats remains largely unexplored. Given the critical importance of understanding the microbial composition within aquaculture systems to ensure food safety and protect public health, this study aimed to generate vital preliminary data by investigating the bacteriome of catfish gills and intestines and pond water environment in Cameroon using 16S rRNA gene amplicon sequencing. The findings revealed a diverse bacterial community (30 phyla, 678 genera, and 1056 species), with Fusobacteria, Bacteroidetes, Proteobacteria, Firmicutes, and Verrucomicrobia collectively representing over 93% of the bacterial community observed. Notably, Fusobacteria emerged as the dominant phylum in catfish gills (49.98%) and intestines (65.3%), while Proteobacteria predominated in the pond water environment (40.24%). Bacteria of genus Cetobacterium dominated all three samples (gills, 49.93%; intestines, 65.19%; and pond water, 23.85%). Furthermore, this study identified many bacterial genera, including potential fish pathogens such as Edwardsiella, Aeromonas, Plesiomonas, and Flavobacterium, and human gut bacteria such as Clostridium and Bacteroides, alongside potential beneficial probiotic bacteria such as Lactococcus spp. The coexistence of both potentially pathogenic and probiotic species underscores ecological complex dynamics within freshwater fish aquaculture and highlights the need for thorough microbial management strategies. This study provides insights into the bacterial landscape of Cameroonian aquaculture, revealing potential risks and benefits of catfish farming.
