The Salmonella, Arizona, Shigella and Aeromonas contents of 39 snails (Achatina achatina) were investigated. Serotyping of the Salmonella isolates revealed the presence of S. manhattan, S. ndolo, S. reading, S. uppsala, and S. typhimurium. Six of 18 Shigella isolates were identified as Sh. sonnei while all the Aeromonas proved to be A. hydrophila. Fifty eight percent of these A. hydrophila isolates were enterotoxigenic, and their toxin was shown to be heat labile. All the A. hydrophila strains were both protease positive and haemolytic: 66.7% being both alpha and beta haemolytic while 33.3% showed only alpha haemolysis.
对39只玛瑙螺（非洲大蜗牛）的沙门氏菌、亚利桑那菌、志贺氏菌和气单胞菌含量进行了调查。沙门氏菌分离株的血清型分析显示存在曼哈顿沙门氏菌、恩多洛沙门氏菌、雷丁沙门氏菌、乌普萨拉沙门氏菌和鼠伤寒沙门氏菌。18株志贺氏菌分离株中有6株被鉴定为宋内志贺氏菌，而所有气单胞菌均被证明是嗜水气单胞菌。这些嗜水气单胞菌分离株中有58%具有产肠毒素性，且其毒素显示为热不稳定型。所有嗜水气单胞菌菌株均为蛋白酶阳性且具有溶血活性：66.7%同时具有α和β溶血活性。而33.3%仅显示α溶血活性。
