The performance of the MicroScan WalkAway PC30 panel for detection of oxacillin resistance was evaluated by use of a collection of 420 staphylococcus isolates. The addition of a cefoxitin test (4 mg/liter) to the oxacillin MIC determination increased its raw performance for Staphylococcus aureus; additional data were required for coagulase-negative staphylococci.

We describe results from a multicenter pilot study evaluating the eQUANT system for rapid generation of a standardized inoculum (0.5 McFarland equivalent) directly from blood cultures positive for target gram-negative bloodstream pathogens for same-day antimicrobial susceptibility testing (AST) by disk diffusion, MicroScan and Vitek2 methods. Out of 167 blood cultures that met study criteria (monomicrobial with one of 9 target gram-negative species), colony counts from eQUANT suspensions of 164 (98.

Rapid antimicrobial drug administration is crucial for the efficient treatment of sepsis or septic shock, but empirical therapy is limited by the increasing prevalence of multidrug-resistant bacteria. Thus, rapid and reliable antimicrobial susceptibility testing (AST) is needed to start appropriate antimicrobial drug administration as quickly as possible. In the present study, we evaluated the performance of the Reveal rapid AST system.

Article Synopsis
  • This study conducted in Rabigh City, Saudi Arabia aimed to identify antimicrobial resistance (AMR) in common pathogenic bacteria within a healthcare facility over a six-month period.
  • Out of 1,933 patient samples, 11.1% showed bacterial growth, with a higher prevalence in patients over 50 years old; the majority were Gram-negative bacteria like E. coli and K. pneumoniae.
  • The findings reveal significant resistance among isolated bacteria, particularly with K. pneumoniae showing increased resistance to carbapenem antibiotics, emphasizing the need for ongoing monitoring of AMR in healthcare environments.

Article Synopsis
  • Rapid antimicrobial susceptibility testing (rAST) from blood cultures is crucial for selecting effective antibiotics for bloodstream infections, with the LifeScale system offering a promising new approach.
  • LifeScale utilizes microfluidic sensors and mechanical resonators to quickly analyze individual microbes and deliver reliable rAST results in under 5 hours, outpacing standard methods.
  • Notably, LifeScale addresses challenges with polymicrobial cultures and shows strong agreement with the current standard of care, potentially allowing for quicker clinical decision-making without the need for confirmatory tests.

Bacterial and Genetic Features of Raw Retail Pork Meat: Integrative Analysis of Antibiotic Susceptibility, Whole-Genome Sequencing, and Metagenomics.

Antibiotics (Basel)

Centre for Healthcare Association Infections, Antimicrobial Resistance and Mycoses, National Institute for Communicable Diseases, a Division of the National Health Laboratory Service, Johannesburg 2192, South Africa.

Article Synopsis
  • A study explores antibiotic resistance in raw retail pork meat, focusing on microbiological and genetic characteristics in Gauteng, South Africa, due to concerns over antibiotic overuse and misuse.
  • Various methods like antibiotic susceptibility testing, whole-genome sequencing, and residue analysis were employed to assess the meat samples, which revealed minimal resistance but identified tetracycline resistance genes.
  • The findings suggest that while antibiotic residues in the meat were within safe limits, the presence of resistance genes could have broader implications for environmental health and the ongoing antibiotic resistance crisis, highlighting the need for further research.
