Meat commonly contain the same Aeromonas spp. which occur in human diarrhoeal and non-diarrhoeal faecal samples. Motile Aeromonas were isolated from 5.6% of total 302 samples. The distribution of the isolates were 5.9 and 5.2% in fresh and frozen samples, respectively. Of the 302 samples taken of the four animal meat species investigated, the genus Aeromonas were isolated in 12.3% of the fresh samples collected from buffalo meat, in 6.5% of the samples collected from sheep meat and 14.0% from the samples collected from the cattle frozen meat samples. The camel meat did not reveal any Aeromonas isolates. Aeromonas hydrophila was isolated as the most prevalent species with 6.8%, followed by Aeromonas caviae with 2.7% and Aeromonas sobria with 2.1% from the total meat samples. Aerolysin toxin gene (aerA) was detected in 3/17 isolates of A. hydrophila isolated from contaminated meat. Infection due to bacterial pathogen with such virulent factor through contact with contaminated meat while handling them, poses health hazards to humans.
肉类通常含有与人类腹泻和非腹泻粪便样本中相同的气单胞菌属。从 302 个总样本中分离出了 5.6%的运动性气单胞菌。在新鲜和冷冻样本中的分离株分布分别为 5.9%和 5.2%。在所调查的四种动物肉类样本中，从新鲜的水牛肉类样本中分离出了 12.3%的气单胞菌属，从绵羊肉类样本中分离出了 6.5%，从冷冻的牛肉类样本中分离出了 14.0%。骆驼肉未发现任何气单胞菌属分离株。从总肉类样本中，分离出的优势种为嗜水气单胞菌（6.8%），其次是豚鼠气单胞菌（2.7%）和气阴杆菌（2.1%）。从污染肉类中分离出的 17 株嗜水气单胞菌中有 3 株携带 aerolysin 毒素基因（aerA）。通过接触受污染的肉类在处理过程中感染这种具有如此毒力因子的细菌病原体，对人类健康构成威胁。
