在肠杆菌科菌类中,大肠和痢疾菌属被认为在三糖铁琼脂培基上是不产生硫化氢的。硫化氢阳性的大肠杆菌已有报导,最近我们检出两组在Tsi琼脂上产生硫化氢的宋内氏痢疾杆菌。一、菌株:两组硫化氢阳性的菌株,一组于7964年自札晃市腹泻病人粪便标本检出。从去氧胆酸盐、枸橼酸盐、乳糖、蔗糖琼脂平板上挑取半透明菌落种入Tsi琼脂和硫化物吲哚 In Enterobacteriaceae, the large intestine and dysentery genus are thought to produce no hydrogen sulfide on the trisaccharide iron agar medium. Hydrogen sulfide-positive E. coli has been reported recently and two sets of Shigella dysenteriae that produce hydrogen sulfide on Tsi agar were detected recently. First, the strain: two groups of positive hydrogen sulfide strains, a group from 79,4 diarrhea in Sapporo patients stool specimens were detected. Translucent colonies were picked from deoxycholate, citrate, lactose, and sucrose agar plates into Tsi agar and sulphide indoles
