T-related bacteriophages isolated from Shigella sonnei.
The properties of three T-related phages-35, 55, and 3201-isolated from Shigella sonnei were studied. They were similar with respect to morphology of plaques, duration of the latent periods, lysis inhibition effect, and serological characteristics. These phages closely resembled the T-even phages. Phages 3201, 35, and 55 had the same host range and receptor specificity as phage T2.
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 کاملIntestinal immunoglobulin A responses in rabbits to a Salmonella typhi strain harboring a Shigella sonnei plasmid.
Salmonella typhi 5076-IC, which contains a plasmid that encodes the form I antigen of Shigella sonnei and which expresses S. typhi 9 and 12 and S. sonnei form I antigens, was used to immunize rabbits via chronically isolated ileal loops. Intestinal immunoglobulin A activity was detected against S. typhi, S. sonnei form I, and S. typhi strain 5076-IC. Thus S. typhi 5076-IC can effectively elicit...
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...
