Abstract

Carnobacterium is a genus of Gram-positive bacteria, within family Carnobacteriaceae, and they are catalase- and oxidase-negative, non-sporing bacteria with properties such as CO2 and L (+)- lactic acid production from glucose, but they are not able to grow on acetate agar. They are ubiquitous lactic acid bacteria and have been isolated from both cold and temperate environments, and they are identified as components of the microbiota in the gastrointestinal (GI) tract of salmonids and several other fish species of which Carnobacterium (piscicola) maltaromaticum, Carnobacterium mobile, Carnobacterium divergens, Carnobacterium alterfunitum, and Carnobacterium inhibens are reported. During the last two decades several studies have revealed that carnobacteria can act as probiotics to promote health benefits of fish, as well as they in ex vivo studies to some extent can out-compete pathogens. In addition to beneficial effects, information is available that some carnobacteria species causing fish disease. The aim of the present review is to present an updated overview of Carnobacterium in fish, with focus on their presence in the GI tract, their use as probiotic supplement and general information on pathogenic carnobacteria.

鱼类中的食肉菌
卡诺杆菌(Carnobacterium)是一种革兰氏阳性菌属,属于卡诺杆菌科,它们是催化酶和氧化酶阴性的无芽孢细菌,具有从葡萄糖产生二氧化碳和 L(+)-乳酸的特性,但它们不能在醋酸盐琼脂上生长。它们是无处不在的乳酸菌,已从寒冷和温带环境中分离出来,并被确认为鲑鱼和其他几种鱼类胃肠道(GI)微生物区系的组成部分,其中有报道称有 Carnobacterium (piscicola) maltaromaticum、Carnobacterium mobile、Carnobacterium divergens、Carnobacterium alterfunitum 和 Carnobacterium inhibens。在过去的二十年中,一些研究表明肉毒杆菌可以作为益生菌促进鱼类的健康,而且在体内外研究中,它们在一定程度上可以战胜病原体。除了有益作用外,还有资料表明,一些肉毒杆菌会导致鱼类疾病。本综述旨在介绍鱼类中肉毒杆菌的最新概况,重点是它们在消化道中的存在、它们作为益生菌补充剂的用途以及有关致病肉毒杆菌的一般信息。
