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...

OBJECTIVE To describe antimicrobial susceptibility testing practices of veterinary diagnostic laboratories in the United States and evaluate the feasibility of collating this information for the purpose of monitoring antimicrobial resistance in bacterial isolates from animals. DESIGN Cross-sectional study. PROCEDURES A questionnaire was mailed to veterinary diagnostic laboratories throughou...

Objective(s) Rapidly growing mycobacteria (RGM) are capable of producing diseases in humans. Since mycobacteria vary in their susceptibility, precise identification is critical for adoption of correct drug therapy. The main aim of this study was molecular identification and evaluation of antimicrobial susceptibility pattern of Iranian clinically isolated Myocbacterium fortuitum. Materials and...

Susceptibility testing of Eikenella corrodens is usually performed by a Mueller-Hinton sheep blood agar dilution (AD) method. However, this method is impractical for testing only a few strains. We compared AD with the broth microdilution method using Haemophilus test medium (HTM) in order to determine the susceptibility of 36 clinical isolates of E. corrodens to eight antimicrobial agents. MICs...

INTRODUCTION Mass spectrometry Matrix-Assisted Laser Desorption-Ionization Time-of-Flight (MALDI-TOF) helps in the rapid identification of microorganisms causing blood stream infection. Rapid and reliable methods are required to decrease the turnaround time for reporting antimicrobial susceptibility results from blood culture isolates. METHODS An evaluation was performed on the reliability of...

An international collaborative study on serotyping and antimicrobial susceptibility testing of eight Salmonella enterica strains was performed to enhance the capacity of national and regional reference laboratories in WHO Global Salm-Surv to conduct Salmonella serotyping and antimicrobial susceptibility testing. A total of 103 laboratories in 60 countries participated. For serotyping, 78% of th...
