The aim of this study was to establish standardized drug susceptibility testing (DST) methodologies and reference MIC quality control (QC) ranges for bedaquiline, a diarylquinoline antimycobacterial, used in the treatment of adults with multidrug-resistant tuberculosis. Two tier-2 QC reproducibility studies of bedaquiline DST were conducted in eight laboratories using Clinical Laboratory and St...
The susceptibility of 135 Streptococcus suis strains isolated from pigs (n = 110) and from humans (n = 25) to 13 antimicrobial agents was studied by microdilution and disc diffusion methods using Mueller-Hinton Agar II (MH) supplemented with either defibrinated sheep blood (MHSB) or horse serum (MHHS). Results were similar for both methods used except for penicillin G whose zone diameters were ...
The assessment of physiochemical and pharmacological properties at early stages of drug discovery can accelerate the conversion of hits and leads into candidates for further development. A strategy for streamlined evaluation of compounds against Mycobacterium tuberculosis in the early preclinical stage is presented in this report. As a primary assay to rapidly select experimental compounds with...
16 Routine application of antimicrobials is the current treatment of choice for rainbow trout 17 fry syndrome (RTFS) or bacterial coldwater disease (BCWD) caused by Flavobacterium 18 psychrophilum. In this study, the antimicrobial susceptibilities of 133 F. psychrophilum 19 isolates, 118 of which were from the UK, were evaluated by broth microdilution and disc 20 diffusion methods following VET...
OBJECTIVES To investigate the reliability of cefoxitin and oxacillin for the detection of mecC-positive Staphylococcus aureus. METHODS The susceptibility to cefoxitin and oxacillin of 62 mecC-positive S. aureus isolates was investigated using broth microdilution, agar dilution, Etest and disc diffusion on different types of media. The data were interpreted for the utility of cefoxitin and oxa...
Pseudomonas aeruginosa is the most common pathogen infecting the lungs of patients with cystic fibrosis (CF). Improved antimicrobial chemotherapy has significantly increased the life expectancy of these patients. However, accurate susceptibility testing of P. aeruginosa isolates from CF sputum may be difficult because the organisms are often mucoid and slow growing. This study of 597 CF isolate...
