Letter in Response to Evaluation of Xpert MRSA Gen 3 and BD MAX MRSA XT for meticillin-resistant Staphylococcus aureus screening in a routine diagnostic setting in a low-prevalence area. Journal of Medical Microbiology. 2017;66(1): 90-95. J Med Microbiol. 2019 Jan 10;: Authors: Rabinowicz S, O'Hare M, Moore LSP, Mughal N Abstract The move towards pathology networks and hub-and-spoke models of medical laboratory service provision has significantly changed the flow of samples, and the impact of results on patients, over recent years. At the same time advances in technology, including rapid, simple to use molecular platforms, are changing the way microbiology results can be utilized. Like many other medical microbiology laboratories, we struggle with this balance for many different sample types and test requests. Work published by Neilson et al. in Journal of Medical Microbiology last year looked at this balance for methicillin-resistant Staphylococcus aureus (MRSA) genotypic diagnostics and suggested significant cost savings when a whole-healthcare economy perspective was adopted. However, as with all changes, implementing MRSA molecular diagnostics in different clinical settings must be considered carefully. We add to this discussion in our accompanying letter, detailing our experience (in a hub-and-spoke medical microbiology laboratory setting) of 'rapid' MRSA molecular diagnostics for day-case surgery where pre-operative assessment had been missed, expl...

During my nine years in the NFL, I ruptured tendons in my fingers, suffered multiple concussions, and broke several bones. I tore my ACL, MCL, and PCL, and completely blew out my left knee. That last injury should have ended my career. But it didn’t. I put myself back together and played through the pain. What finally took me down? A tiny bug I had never heard of and couldn’t see. A drug-resistant staph infection called methicillin-resistant Staphylococcus aureus cost me my NFL career—and almost my life. MRSA is one of many deadly, antibiotic-resistant infections. Together, these “superbugs” k...

Conclusions: The pattern of airway colonisation in the Indian setting is different from the Caucasian population, and P. aeruginosa and Burkholderia cepacia complex appear early. Colonisation with P. aeruginosa benefits from therapy. In case of infection, care must be taken while initiating empiric therapy. It should be based on local antibiograms to prevent the emergence of resistant microbes.

Publication date: November 2019Source: Saudi Journal of Biological Sciences, Volume 26, Issue 7Author(s): Asmaa FadenAbstractWe assessed the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) strains on surfaces of hospital dental clinics. Specimens were obtained from 5 clinically symptoms-free patients of five different specialties clinics (Implantology, Pediatric Dentistry, Prosthetics, Restorative Dentistry, and Oral Medicine) of the Dental Clinic Hospital of King Saud University before and after each patient. A Q-tip swabs were used from 10 surfaces in each clinic (Arm rest of dental chair, floor beneath ...

AbstractHistorically, vancomycin has been considered a primary therapeutic option for treating infections withStaphylococcus aureus, but isolates with reduced vancomycin susceptibility (SA-RVS) (MIC  ≥ 4 μg/mL) have emerged. Telavancin, a semisynthetic lipoglycopeptide, is an alternative treatment option forS. aureus, but data examining telavancin activity against SA-RVS are limited. In the present study, we characterize 300 isolates ofS. aureus isolates (50 vancomycin-susceptible (VSSA) isolates and 250 SA-RVS isolates) from a large tertiary care, academic medical center, 51.8% of which were methi...

AbstractMethicillin-resistantStaphylococcus aureus (MRSA) is an important cause of infections in humans. Photodynamic therapy using blue light (450  nm) could possibly be used to reduce MRSA on different human tissue surfaces without killing the human cells. It could be less harmful than 300–400 nm light or common disinfectants. We applied blue light ± riboflavin (RF) to MRSA and keratinocytes, in an in vitro liquid layer model, and compar ed the effect to elimination using common disinfection fluids. MRSA dilutions (8 × 105/mL) in wells were exposed to blue light (450  nm) &...

Methicillin-resistant Staphylococcus aureus (MRSA) is a common pathogenic bacterium that causes nosocomial and community-acquired infections. Annual report of nationwide survey in Japan revealed MRSA was detected at 100% of the hospitals in 2017 (Japan Nosocomial Infections Surveillance (JANIS), 2019). Moreover, MRSA infection can cause severe illness not only in immunocompromised patients but also in healthy people. Although anti-MRSA therapeutic agents are clinically available, MRSA infection can be life threatening.

The high potency of PBL relative to CW blue light makes it a suitable antimicrobial for suppressing bacterial growth in biofilms as wel...
