conclusions the β-lactamase disk test is appropriately sensitive to detect esbls in mdr isolates of e. coli. background most urinary tract infections (utis) are caused by escherichia coli (e. coli) species. due to infections outbreaks of e. coli strains with multiple mechanisms of resistance to β-lactam antibiotics, the sensitivity of confirmatory tests to detect the extended spectrum β-lactama...

INTRODUCTION Detection of heterogeneous vancomycin-intermediate Staphylococcus aureus (hVISA) is currently problematic. Although the population analysis profile with area under the curve (PAP-AUC) is the gold standard for detecting hVISA strains, this method is time consuming. This study aimed to induce vancomycin non-susceptible Staphylococcus aureus isolates in methicillin-resistant S. aureus...

To evaluate different methods for the identification of methicillin-resistant Staphylococci and their reliability, 112 Staphylococcal isolates (32 Staphylococcus aureus isolates and 80 coagulase negative Staphylococci isolates “CoNS”) were collected from 118 nasal swab cultures and were subjected to three methods to detect oxacillin susceptibility of the isolates. The three methods were oxacill...

The standardized disk diffusion test, in which a 10-micrograms enoxacin disk is used, was performed and microbroth dilution MICs were determined to establish individual test control values with Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853, Staphylococcus aureus ATCC 25923, and S. aureus ATCC 29213. In addition, regression analysis correlating inhibitory zone diameter with MICs...

Mannitol salt agar was evaluated for detection of oxacillin resistance in 136 Staphylococcus aureus isolates. All mecA-positive isolates (n = 54) were correctly categorized as oxacillin resistant by the disk diffusion test (1-microgram disk; zone diameter, < 16 mm); the specificity was 97.6%. Agar screening (2 micrograms of oxacillin per ml) revealed a sensitivity of 98.1% and a specificity of ...

The management of infections due to A. baumannii is difficult because of rapidly developing resistance, however, tigecycline, a glycylcycline antimicrobial, is in use for several years. In the present study, it was aimed to determine the susceptibility rates of A. baumannii to tigecycline. A total of 90 A. baumanni isolates were tested using three methods such as disk diffusion, broth microdilu...

discussion our results indicated that agar screening was superior to oxacillin disk agar diffusion. a comparison between the antibiotic sensitivity patterns of the mrcns and the methicillin-susceptible coagulase-negative staphylococci (mscns) showed that the mrcns were predominantly multiple-drug resistant isolates as the simultaneous resistance rate to 4 or more antibiotics in the mrcns and ms...
