background: we reviewed the monthly laboratory surveillance reports and hospital laboratory database in dhahira region, oman. methods: all patients for whom a stool sample examination request was made from 1 st january 2002 to 31 st december 2006 (5 years) were included in the study. antimicrobial resistance pattern was studied for 2 years period. the cultures were done using standard laborator...

Antimicrobial resistance is an urgent global health challenge in human and veterinary medicine. Wild animals are not directly exposed to clinically relevant antibiotics; however, antibacterial resistance in wild animals has been increasingly reported worldwide in parallel to the situation in human and veterinary medicine. This underlies the complexity of bacterial resistance in wild animals and...

The few reports from Africa on sensitivity determinations of Neisseria gonorrhoeae suggest that there is an increasing resistance in the strains, as has been found in other parts of the world. In the current study, the penicillin sensitivities and β-lactamase production of 80 consecutive strains of N. gonorrhoeae isolated from cases of acute urethritis in African men in Ibadan were studied. Of ...

A total of 187 isolates from 470 clinical specimens were collected from three hospitals in El-Minia governorate and identified as 132 Staphylococcus aureus strains and 55 coagulase-negative staphylococci (CoNS) strains. Susceptibility of isolates to antimicrobial agents was tested by the agar dilution method. The isolated S. aureus strains showed low resistance to vancomycin (1.5%), amikacin (2...

Introduction In this era of modern medicine, antimicrobial resistance can be regarded as a major health calamity. The emergence multidrug-resistant (MDR) Pseudomonas aeruginosa strains poses therapeutic challenges and lead to treatment failure in hospitalized patients. This study was conducted determine various types β-lactamases among MDR P. isolates recovered from patients.

For 2013-2014, we prospectively identified US adults with flank pain, temperature >38.0°C, and a diagnosis of acute pyelonephritis, confirmed by culture. Cultures from 453 (86.9%) of 521 patients grew Escherichia coli. Among E. coli isolates from 272 patients with uncomplicated pyelonephritis and 181 with complicated pyelonephritis, prevalence of fluoroquinolone resistance across study sites wa...

In the last decades, considerable attention has been paid to the collection of antimicrobial resistance data, with the aim of monitoring non-wild-type isolates. This monitoring is performed based on minimum inhibition concentration (MIC) values, which are collected through dilution experiments. We present a semi-parametric mixture model to estimate the entire MIC density on the continuous scale...

This article summarizes the current literature describing how antimicrobial stewardship interventions impact antimicrobial resistance. Discussion includes why we need stewardship, how to collaborate with team members, and the evidence of stewardship's impact on resistance.

The development of antimicrobial resistance among gram-negative pathogens has been progressive and relentless. Pathogens of particular concern include extended-spectrum β-lactamase-producing Enterobacteriaceae, carbapenem-resistant Enterobacteriaceae, and multidrug-resistant Pseudomonas aeruginosa. Classic agents used to treat these pathogens have become outdated. Of the few new drugs available...
