BACKGROUND The anaerobic spirochetes Brachyspira hyodysenteriae and Brachyspira pilosicoli cause diarrheal diseases in pigs. Their fastidious nature has hampered standardization of methods for antimicrobial susceptibility testing. For monitoring of antimicrobial susceptibility wild type cutoff values are needed to define where the wild type distribution of MICs ends and no approved cutoffs are ...

We isolated Enterococcus species that colonized in the African buffalo (Syncerus caffer) in order to investigate their genetic relatedness and antimicrobial susceptibility. A total of 219 isolates were obtained and a 16S rRNA gene sequence analysis showed they were classified into Enterococcus avium, E. casseliflavus, E. faecalis, E. faecium, E. hirae, or E. mundtii. Multilocus sequence typing ...

BACKGROUND Urinary tract infections (UTIs) are common in dogs. The responsible bacterial populations have evolved with increasing resistance to many antimicrobials. OBJECTIVE To characterize the antimicrobial susceptibility patterns of canine urinary tract isolates over a 51-month period. ANIMALS One thousand six hundred and thirty-six bacterial isolates from 1,028 dogs. METHODS Aerobic b...

Fifty random clinical isolates of Haemophilus parainfluenzae were tested for their susceptibility to 10 antibiotics by a microtiter broth dilution method. Three of the strains tested were resistant to ampicillin, whereas eight were resistant to tetracycline. All strains tested were susceptible to chloramphenicol, kanamycin, gentamicin, cephalothin, and colistin. The ranges of minimal inhibitory...

Minimal inhibitory concentration determinations and disk diffusion and Autobac 1 susceptibility tests were performed on 22 strains of Aeromonas hydrophila. Eleven of the strains had discrepancies between Autobac and disk diffusion or minimal inhibitory concentration results. These discrepancies occurred with the beta-lactam antibiotics, primarily carbenicillin and cephalothin. It is recommended...

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: Infections caused by multidrug-resistant (MDR) Acinetobacter baumannii have become a major treatment challenge, requiring the re-introduction of polymyxins into clinical practice. Given this situation, the emergence of polymyxin B resistance is expected. Recently, increased antimicrobial susceptibility among in vitro passaging of colistin-resistant A. baumannii isolates was observed ...

Cefoperazone is a new cephalosporin with a very wide spectrum of activity, including activity against Pseudomonas aeruginosa. It has less activity on enterococci and Acinetobacter. Of the 459 selected bacterial strains tested in this study, only 1.5% (7 strains and 6 genera) had minimum inhibitory concentrations of >128 ,ug/ml. For a minimum inhibitory concentration breakpoint of <32 p.g/ml (su...
