Infections due to anaerobic bacteria can be severe and life-threatening. Susceptibility testing of anaerobes is not frequently performed in laboratories, but such testing is important to direct appropriate therapy. Anaerobic resistance is increasing globally, and resistance trends vary by geographic region. An overview of a variety of susceptibility testing methods for anaerobes is provided, an...

a total of 385 urine specimens from suspected urinary tract infections were subjected to bacteriological analysis and susceptibility testing at a major university hospital laboratory in tehran. a battery of eight beta-iactam antibiotics, commonly prescribed in iran, and three third-generation cephalosporins (ceftazidime, ceftriaxone and ceftizoxime) that are usually reserved for limited use in ...

The in vitro susceptibility of an infecting organism to the antimicrobial agent selected for therapy is one of several factors that influence the likelihood that therapy for an infection will be successful. To appreciate the value of antifungal susceptibility testing, it is helpful to review the overall predictive utility of antibacterial susceptibility testing. After >30 years of study, in vit...

In this study, 24 standard nontuberculous mycobacteria (NTM) species strains including 12 slowly growing mycobacteria strains and 12 rapidly growing mycobacteria strains were subjected to drug susceptibility testing using microplate Alamar Blue assay-based 7H9 broth. The most active antimicrobial agents against the 24 NTM strains were streptomycin, amikacin, the fluoroquinolones, and the tetrac...

Sir, The NCCLS has published guidelines for the susceptibility testing of fastidious organisms. Following these guidelines for the assessment of a new trinem, sanfetrinem (GV 104326), against Neisseria spp. we obtained unexpectedly high MICs and therefore undertook a study to compare MICs obtained on a variety of media. The media compared were as follows: medium A, IsoSensitest agar (Unipath, B...
