متن کاملCTX-M-3 type beta-lactamase producing Shigella sonnei isolates from pediatric bacillary dysentery cases.
In this study, 153 clinical isolates of Shigella were screened for extended-spectrum beta-lactamase (ESBL) production by double-disk synergy test. After being confirmed by the combined disk-test and inhibitor-combined E-test strips, all positive isolates were tested for the bla gene by PCR and the enzymes by isoelectric focusing. DNA sequencing of PCR products revealed that five Shigella sonnei...
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 کاملOutbreak of dysentery associated with ceftriaxone-resistant Shigella sonnei: First report of plasmid-mediated CMY-2-type AmpC beta-lactamase resistance in S. sonnei.
We document the first report of plasmid-encoded CMY-2-type AmpC beta-lactamase identified among Shigella sonnei isolates resistant to ceftriaxone and obtained after an outbreak of bacillary dysentery in Taiwan. One hundred eighty-two children in two elementary schools in Yu-Li, Taiwan, where an outbreak occurred after a typhoon hit this area in 2001, were enrolled in this study. Clinical and ep...
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,...
