Macrolide-Resistant Shigella sonnei
نویسندگان
چکیده
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.

Escherichia coli as Reservoir for Macrolide Resistance Genes
The plasmid-borne mph(A) gene that confers resistance to azithromycin and has recently emerged in Shigella sonnei is present in multidrug- and non-multidrug-resistant Escherichia coli isolates from 4 continents. Further spread of mph(A) to Shigella and Salmonella spp. may be expected.
متن کاملESBL-Producing and Macrolide-Resistant Shigella sonnei Infections among Men Who Have Sex with Men, England, 2015
In England in 2015, Shigella sonnei isolates from men who have sex with men produced extended-spectrum β-lactamases and exhibited macrolide resistance. Whole-genome sequencing showed a close relationship among the isolates, which harbored a plasmid that was previously identified in a shigellosis outbreak among this population but has acquired a mobile element.
متن کاملAzithromycin Resistance in Shigella spp. in Southeast Asia.
Infection by Shigella spp. is a common cause of dysentery in Southeast Asia. Antimicrobials are thought to be beneficial for treatment; however, antimicrobial resistance in Shigella spp. is becoming widespread. We aimed to assess the frequency and mechanisms associated with decreased susceptibility to azithromycin in Southeast Asian Shigella isolates and use these data to assess appropriate sus...
متن کاملHigh-Quality Draft Genome Sequences for Four Drug-Resistant or Outbreak-Associated Shigella sonnei Strains Generated with PacBio Sequencing and Whole-Genome Maps
Drug-resistant Shigella sonnei poses a clinical and public health challenge. We report here the high-quality draft whole-genome sequences of four outbreak-associated S. sonnei isolates; three were resistant to two or more antibiotics, and one was resistant to streptomycin only.
متن کاملCiprofloxacin-Resistant Shigella sonnei among Men Who Have Sex with Men, Canada, 2010
In 2010, we observed isolates with matching pulsed-field gel electrophoresis patterns from 13 cases of ciprofloxacin-resistant Shigella sonnei in Montréal. We report on the emergence of this resistance type and a study of resistance mechanisms. The investigation suggested local transmission among men who have sex with men associated with sex venues.
