Abstract

The enterotoxigenicity of 170 Aeromonas strains isolated from different sources (food poisoning, random food sampling, water, faeces) was examined by the suckling mouse test. The strains were grown on Syncaye culture medium covered with sterilized membrane for Kiil-kidney. The culture supernatants were inoculated orally. Ileal loop dilatation was compared to that produced by the international standard enterotoxic Escherichia coli B7A (O148 : H28) and B2C (O6 : H16) strains. Of the 87 Aeromonas hydrophila strains 69, of the 76 Aeromonas punctate subsp. caviae strains 9, the 6 Aeromonas punctata subsp. punctata strains 5, and 1 Aeromonas salmonicida subsp. achromogenes gave a positive reaction in the test.

摘要

通过乳鼠试验检测了从不同来源（食物中毒、随机食品采样、水、粪便）分离出的170株气单胞菌的产肠毒素能力。这些菌株在覆盖有用于基尔肾的无菌膜的Syncaye培养基上生长。将培养上清液经口接种。将回肠袢扩张情况与国际标准产肠毒素大肠杆菌B7A（O148:H28）和B2C（O6:H16）菌株所产生的情况进行比较。在87株嗜水气单胞菌菌株中，69株呈阳性反应；在76株点状气单胞菌豚鼠亚种菌株中，9株呈阳性反应；在6株点状气单胞菌点状亚种菌株中，5株呈阳性反应；1株杀鲑气单胞菌无色亚种菌株在试验中呈阳性反应。
