Colicin typing of Shigella sonnei.
The colicin typing method for differentiating epidemic strains of Shigella sonnei was evaluated. Forty percent of the strains were untypable, but the method divides 60% of the strains into 15 established colicin types. The method has reasonably good reproducibility, but should not be interpreted with the same degree of confidence as some other characteristics such as serotypes. For this reason,...
متن کاملBacteriophage typing of Shigella sonnei.
A bacteriophage-typing schema was developed for differentiating strains of Shigella sonnei. Sixty-seven bacteriophages were obtained from other collections, and 36 bacteriophages were isolated from sewage. From these 103 bacteriophages, a provisional set of 12 was chosen by computer analysis as being the most sensitive in differentiating strains of S. sonnei isolated in the United States. The p...
متن کاملColicin typing as an epidemiological tool in the investigation of outbreaks of Shigella sonnei.
Shigella sonnei has become the most frequently reported cause of shigellosis in the United States. Since Shigella subgroup D has no other serotypes, colicin production has been used as a basis for differentiating and identifying epidemiologically related strains. The results of colicin typing 115 cultures of S. sonnei from eight outbreaks of shigellosis occurring in widely separated regions of ...
متن کاملMacrolide-Resistant Shigella sonnei
Shigella sonnei UCN59, isolated during an outbreak of S. sonnei in January 2007, was resistant to azithromycin (MIC 64 mg/L). The isolate contained a plasmid-borne mph(A) gene encoding a macrolide 2 -phosphotransferase that inactivates macrolides. Emergence of the mph(A) gene in S. sonnei may limit usefulness of azithromycin for treatment of shigellosis.
متن کاملColicin type 7 produced by majority of Shigella sonnei isolated from Thai patients with diarrhoea
Thirty one out of 153 strains of Shigella sonnei isolated from Thai patients with diarrhoea showed antibacterial activity against S. sonnei by agar well diffusion method. All of them harbor plasmids with the genetic determination of colicin type 7 (Js) gene but without colicin E and colicin U gene. The PCR product obtained from strain 35/44 was shown to be the gene for colicin type 7 lytic prot...
