The aim of this review was to summarize the current knowledge regarding the effects of aeromonosis on fish oxidative status. The bibliographic survey was carried out on the research platforms: Scopus and Science Direct. The keywords ‘Aeromonas’, ‘fish’ and ‘oxidative status’ (or ‘oxidative stress’, ‘oxidative damage’ and similar terms) were used. Scientific papers and short communications were considered. Studies involving fish aeromonosis and enzymatic or non-enzymatic markers of oxidative status were selected. The results of antioxidant enzymes activities/expressions after infection lack consistency, suggesting that these findings should be interpreted with caution. Most of the analysed studies pointed to an increase in reactive oxygen species, malondialdehyde and protein carbonylation levels, indicating possible oxidative damage caused by the infection. Thus, these three biomarkers are excellent indicators of oxidative stress during infection. Regarding respiratory burst activity, several studies have indicated increased activity, but other studies have indicated unchanged activity after infection. Nitric oxide levels also increased after infection in most studies. Therefore, it is suggested that the fish’s immune system tries to fight a bacterial infection by releasing reactive oxygen and nitrogen species.

与气单胞菌属相关的鱼类感染：对氧化状态影响的综述

本综述的目的是总结当前关于气单质增多症对鱼类氧化状态影响的知识。书目调查是在研究平台上进行的：Scopus 和 Science Direct。关键词 '气单胞菌'、'鱼'和'氧化状态'（或'氧化应激'、'氧化损伤'和类似术语）被使用。考虑了科学论文和简短的交流。选择了涉及鱼类气单沉着症和氧化状态的酶促或非酶促标记的研究。感染后抗氧化酶活性/表达的结果缺乏一致性，表明应谨慎解释这些发现。大多数分析的研究都指出活性氧、丙二醛和蛋白质羰基化水平增加，表明感染可能引起氧化损伤。因此，这三种生物标志物是感染期间氧化应激的极好指标。关于呼吸爆发活动，几项研究表明活动增加，但其他研究表明感染后活性不变。在大多数研究中，一氧化氮水平也在感染后增加。因此，建议鱼的免疫系统试图通过释放活性氧和氮物种来对抗细菌感染。
