Abstract

All 17 Salmonella typhi strains tested from the epidemic in Mexico carried R factors of compatibility group H, conferring resistance to chloramphenicol, streptomycin, tetracycline, and sulfonamides. Some S. typhi strains carried, in addition, non-conjugative, ampicillin resistance plasmids and R factors of the I or A-C complex. All 20 Shigella dysenteriae 1 strains tested of epidemic origin carried O-group R factors. Ampicillin resistance in S. dysenteriae 1 was not proved to be plasmid borne. R factors of group H were not identified in any of the tested Mexican isolates other than S. typhi, but R factors of group O were identified in Escherichia coli, Shigella flexneri, and one strain of S. typhi, as well as in the epidemic S. dysenteriae. An R factor was identified which seemed to have two compatibility specificities, groups Iomega and O.

摘要

从墨西哥疫情中检测的所有17株伤寒沙门氏菌都携带H相容性群的R因子,对氯霉素、链霉素、四环素和磺胺类药物具有抗性。此外,一些伤寒沙门氏菌菌株还携带非接合性氨苄青霉素抗性质粒以及I或A - C复合体的R因子。所有检测的20株痢疾志贺氏菌1型菌株均来自疫情源头,都携带O群R因子。痢疾志贺氏菌1型中的氨苄青霉素抗性未被证明是由质粒携带的。除伤寒沙门氏菌外,在任何检测的墨西哥分离株中均未鉴定出H群R因子,但在大肠杆菌、弗氏志贺氏菌、一株伤寒沙门氏菌以及疫情中的痢疾志贺氏菌中鉴定出了O群R因子。鉴定出一种似乎具有两种相容性特异性的R因子,即Iω群和O群。
