Antimicrobial drug resistance of Salmonella enterica serovar typhi in asia and molecular mechanism of reduced susceptibility to the fluoroquinolones.
This study describes the pattern and extent of drug resistance in 1,774 strains of Salmonella enterica serovar Typhi isolated across Asia between 1993 and 2005 and characterizes the molecular mechanisms underlying the reduced susceptibilities to fluoroquinolones of these strains. For 1,393 serovar Typhi strains collected in southern Vietnam, the proportion of multidrug resistance has remained h...
متن کاملIn vivo selection for transmissible drug resistance in Salmonella typhi during antimicrobial therapy.
We report the recovery of Salmonella typhi that acquired resistance to ampicillin, chloramphenicol, trimethoprim-sulfamethoxazole, and gentamicin subsequent to multiple antibiotic therapy. Escherichia coli and Klebsiella pneumoniae isolates which were recovered from the same stool sample displayed identical resistance patterns. Agarose gel electrophoresis revealed that S. typhi and laboratory-d...
متن کاملAntimicrobial susceptibility of Salmonella Typhi in India.
BACKGROUND Typhoid fever continues to remain a major public health problem, especially in regions such as Gulbarga, due to poor sanitation and personal hygiene. Gulbarga region is often prone to enteric fever outbreaks and is an endemic region of typhoid fever. Enteric fever caused by Salmonella Typhi has not been adequately explored in this region. METHODOLOGY A total of 95 isolates of S. Ty...
متن کاملIntegron-associated antibiotic resistance in Salmonella enterica serovar typhi from Asia.
Eighteen of 25 isolates of Salmonella enterica serovar Typhi were multidrug resistant and contained class 1 integrons with a single cassette, dfrVII or aadA1. The dfrVII-containing integron was likely borne on an IncHI1 plasmid. Salmonella serovar Typhi could become resistant to broad-spectrum cephalosporins by integrating cassettes, such as veb-1, a common cassette in Asia.
متن کاملSpurious sulfamethoxazole-trimethoprim resistance of Salmonella typhi.
Several studies have identified thymidine excess in susceptibility test media as the cause of spurious resistance of various bacteria to sulfamethoxazole-trimethoprim. We document the phenomenon in Salmonella typhi and Salmonella paratyphi-A and demonstrate its occurrence in 3 of 17 (18%) lots of Mueller-Hinton agars now in use in major medical laboratories in Lima, Peru. The findings are parti...
