چکیده

Antimicrobial susceptibility was analyzed for 354 typhoidal Salmonella isolates collected during 1999-2012 in the Netherlands. In 16.1% of all isolates and in 23.8% of all isolates that showed increased MICs for ciprofloxacin, the MIC for azithromycin was increased. This resistance may complicate empirical treatment of enteric fever.

Case report: failure under azithromycin treatment in a case of bacteremia due to Salmonella enterica Paratyphi A

BACKGROUND Limited information is available regarding the clinical efficacy of azithromycin for the treatment of enteric fever due to fluoroquinolone-resistant Salmonella Typhi and Salmonella Paratyphi among travelers returning to their home countries. CASE PRESENTATION We report a case of a 52-year-old Japanese man who returned from India, who developed a fever of 39°C with no accompanying s...

In vitro activity of azithromycin in Salmonella isolates from Pakistan.

INTRODUCTION Enteric fever is caused by Salmonella enterica serovars Typhi and Paratyphi A, B and C. It is a significant public health issue in Pakistan, which is exacerbated by a high level of resistance some isolates display to drugs routinely used in treatment. Azithromycin may be a treatment option for such isolates. METHODOLOGY We determined the minimum inhibitory concentrations (MICs) o...

Antimicrobial susceptibility to azithromycin among Salmonella enterica isolates from the United States.

Due to emerging resistance to traditional antimicrobial agents, such as ampicillin, trimethoprim-sulfamethoxazole, and chloramphenicol, azithromycin is increasingly used for the treatment of invasive Salmonella infections. In the present study, 696 isolates of non-Typhi Salmonella collected from humans, food animals, and retail meats in the United States were investigated for antimicrobial susc...

In vitro effects of azithromycin on Salmonella typhi: early inhibition by concentrations less than the MIC and reduction of MIC by alkaline pH and small inocula.

To explain good clinical results of azithromycin in patients with typhoid fever, 10 strains of Salmonella typhi were grown in cation-adjusted Mueller-Hinton broth. MICs of azithromycin were 4-16 mg/L. At a sub-MIC of 2 mg/L, early inhibition of growth was shown at 2, 4 and 8 h of incubation, but at 24 and 48 h growth to turbidity occurred. At 4 mg/L, inhibition occurred up to 8 h, after which g...

In vitro activity of azithromycin against nontyphoidal Salmonella enterica.

The in vitro activity of azithromycin against 1,237 nontyphoidal Salmonella enterica isolates collected from Finnish patients between 2003 and 2008 was investigated. Only 24 (1.9%) of the isolates tested and 15 (5.1%) of the 294 isolates with reduced fluoroquinolone susceptibility had azithromycin MICs of >or=32 microg/ml. These data show that azithromycin has good in vitro activity against non...
