Clinical isolates of Aeromonas (13 Aeromonas caviae), 8 Aeromonas hydrophila, 3 Aeromonas spp., and 2 Aeromonas media recovered from diarrheal feces of children were submitted to the suicide phenomenon test and investigated at intervals of 24 h for up to 120 h. The same isolates were also stimulated by repeated passages in broth for ten days before the test. After the bacterial stimulus, a decreases in the number of aeromonads with suicidal capacity was observed. The suicide phenomenon was expressed after 72 h of incubation in only some isolates. The results show that the suicide phenomenon can be prevented by stimulation of bacterial metabolism.
从儿童腹泻粪便中分离出的嗜水气单胞菌临床菌株（13株豚鼠气单胞菌）、8株嗜水气单胞菌、3株气单胞菌属菌株和2株中间气单胞菌，进行自杀现象试验，并每隔24小时进行一次调查，最长持续120小时。在试验前，同样的菌株还在肉汤中反复传代培养十天以进行刺激。细菌受到刺激后，观察到具有自杀能力的气单胞菌数量减少。仅在一些菌株培养72小时后出现自杀现象。结果表明，细菌代谢的刺激可预防自杀现象。
