Genotypic and phenotypic variations in methicillin-resistant Staphylococcus aureus isolates from outpatient, inpatient and nursing homes.

CONCLUSION: This report contributes to the existing understanding of evolutionary epidemiology of antibiotic resistance in MRSA. The diversity of MRSA isolates and unique environmental preferences for each profile highlights the importance of epidemiological knowledge of MRSA distribution to determine the best treatment for patients in both community and hospital settings.

LemeeAbstractThermochemolysis-GC-MS was used to characterize Methicillin resistant Staphylococcus aureus (MRSA) and a predatory actinobacteria isolated from Moroccan marine water through their membrane fatty acids released as methyl esters (FAMEs).FAMEs from MRSA were dominated by branched iso and anteiso C15, straight C18 and C20 whereas the predatory actinobacteria was dominated by branched C14, iso and anteiso C15, and straight C16. The iso to ant...

ConclusionsWe report a high prevalence of MRSA among swine farm workers, with higher colonization rates associated with intensive breeding and animal exposure. Our findings suggest unidirectional animal-to-human transmission of LA-MRSA and denote the high zoonotic transmissibility of the ST398 livestock clade.

ConclusionsIn a model of osteomyelitis induced by MRSA, despite the failure in demonstrating antibacterial effectiveness of NBD peptide in vivo, the results suggest antibiotics in conjunction with NBD peptide to possibly have promising therapeutic potential in osteomyelitis.

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.

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...
