Macrolide-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 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 کاملAmpicillin resistance of Shigella sonnei.
The ampicillin resistance of clinical isolates of Shigella sonnei is due to beta-lactamase production. Two kinds of resistance are found: low level, nontransmissible; and high level, tranmissible. The nontransmissible type of resistance results from a chromosomal mutation which increases the production of a beta-lactamase that hydrolyses cephalosporins relatively rapidly and gives cephalothin r...
متن کاملSalicin fermentation by Shigella sonnei.
Shigella species are generally considered to be unable to ferment salicin (Breed, Murray, and Smith, Bergey's Manual of Determinative Bacteriology, The Williams & Wilkins Co., Baltimore, 1957; Kauffmann, Enterobacteriaceae, E. Munksgaard, Copenhagen, 1950; Edwards and Ewing, Identification of Enterobacteriaceae, Burgess Publishing Co., Minneapolis, 1955). Recently, however, Ser6ny (Acta Microbi...
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...
