The in vitro susceptibility of group D streptococci (enterococci) to ampicillin was studied comparing the results obtained in Mueller-Hinton broth (MHB) with those obtained in normal human serum (NHS). The rate of enterococcal killing was consistently faster in NHS than in MHB at equivalent ampicillin concentrations. Whereas an increasing media pH appeared to decrease the susceptibility of ente...

OBJECTIVE To observe the biochemical characters and antibiotic susceptibility of isolated Staphylococcus aureus (S. auerus) strains against some conventional and traditional antibiotics. METHODS Thirty post operative pathogenic isolated S. aureus strains were used in this study. Bacterial culture was done in Mueller-Hinton broth at 37 °C. Characters of these strains were determined by traditi...

BACKGROUND AND OBJECTIVE Early determination of antibacterial susceptibility increases the success of therapy, decreases unnecessary use of antibacterial agents and side-effects, and lowers the overall healthcare cost. MATERIALS AND METHODS A rapid colorimetric method for antibacterial susceptibility testing named Qui-Sensitest (Inovative Biotechnology Organization, Istanbul, Turkey) was eval...

Rapid antimicrobial susceptibility testing (AST) would decrease misuse and overuse of antibiotics. The "holy grail" of AST is a phenotype-based test that can be performed within a doctor visit. Such a test requires the ability to determine a pathogen's susceptibility after only a short antibiotic exposure. Herein, digital PCR (dPCR) was employed to test whether measuring DNA replication of the ...

Cefazolin and cephalothin disk susceptibility and minimal inhibitory concentration determinations were conducted on 591 clinical isolates. Cefazolin demonstrated superior activity, as shown by lower minimal inhibitory concentrations, and a greater percentage of isolates inhibited in the disk susceptibility test. The cephalothin antibiotic class disk by the standard Bauer-Kirby method failed to ...

aspergillus terreus is emerging as an etiologic agent of invasive aspergillosis among patients undergoing cancer chemotherapy, haematopoetic stem-cell transplantation, or solid organ transplantation worldwide. infections caused by aspergillus terreus has become important due to less susceptibility to antifungal drags, resistant to amphotericin b and therefore, poor clinical outcome and higher m...

BACKGROUND & OBJECTIVES Reliable methods of detection of antimicrobial resistance are of paramount importance in the treatment and management of infections caused by Haemophilus influenzae. The objective of the present study was to compare and evaluate the performance of disc diffusion and E test (Epsilometer test) with agar dilution method for antimicrobial susceptibility testing of H. influen...

conclusions the presence of bft gene in b. fragilis isolates wouldnot certainly result in diarrheaamong patients. there is not enough accordance between ddm and swedish e tests for antimicrobial susceptibility of b. fragilis for some antibiotics, although in other cases a good agreement was observed. background enterotoxigenic bacteroides fragilis (etbf) are one of the most important anaerobic ...

Isolates of Staphylococcus aureus from bovine clinical and subclinical mastitis were tested for ß-lactamase production and antimicrobial susceptibility pattern. Beta-lactamase production was assessed by penicillin-phenol red acidometric test. Antimicrobial susceptibility was tested by measuring MIC by Resazurin dye broth microdilution method. Forty per cent of isolates tested were positive for ...
