Changing epidemiology of meticillin-resistant Staphylococcus aureus in 42 hospitals in the Dutch-German border region, 2012 to 2016: results of the search-and-follow-policy.

We describe MRSA colonisation/infection and bacteraemia rate trends in Dutch-German border region hospitals (NL-DE-BRH) in 2012-16.MethodsAll 42 NL-DE BRH (8 NL-BRH, 34 DE-BRH) within the cross-border network EurSafety Health-net provided surveillance data (on average ca 620,000 annual hospital admissions, of these 68.0% in Germany). Guidelines defining risk for MRSA colonisation/infection were reviewed. MRSA-related parameters and healthcare utilisation indicators were derived. Medians over the study period were compared between NL- and DE-BRH.ResultsMeasures for MRSA cases were similar in both countries, however defining patients at risk for MRSA differed. The rate of nasopharyngeal MRSA screening swabs was 14 times higher in DE-BRH than in NL-BRH (42.3 vs 3.0/100 inpatients; p

ConclusionsThe sustained potent activity of telavancin against US S. aureus isolates (100% susceptible) and the high rates of MRSA and MDR MRSA in the USA support the continued use of telavancin to treat indicated serious infections caused by S. aureus.

ConclusionsIntensive reinforcement of infection control practices, strict cohorting of ex-utero transfers, universal surveillance on admission, and improvement in HH and environmental hygiene compliance were key to infection prevention and control measures, resulting in elimination of MRSA transmission in our neonatal unit.

CONCLUSIONS Our findings reinforce the idea that MSSA and MRSA strains should be carefully monitored, owing to their high pathogenic potential.

Dalman, Jhalka Kadariya, Dylan Grenier, Tara C. SmithBackgroundMethicillin-resistant Staphylococcus aureus (MRSA) is common in medical institutions. We sought to examine the prevalence of S aureus on environmental surfaces in nursing homes and to obtain molecular information on contaminating strains.MethodsA total of 259 environmental samples were collected from 7 different nursing homes in Northeast Ohio (NEO), from suburban, urban, and rura...

Antimicrobial drug discovery against drug-resistant bacteria is an urgent need. Beyond agents with direct antibacterial activity, anti-virulent molecules may also be viable compounds to defend against bacterial pathogenesis. Using a high throughput screen (HTS) that utilized, Caenorhabditis elegans infected with methicillin-resistant Staphylococcus aureus (MRSA) strain of MW2, we identified 4-(1,3-dimethyl-2,3-dihydro-1H-benzimidazol-2-yl)phenol (BIP). Interestingly, BIP had no in vitro inhibition activity against MW2, at least up to 64 µg/mL. The lack of direct antimicrobial activity suggests that BIP could inhibit ...

Khaled M. A. Elzorkany, Asmaa M Elbrolosy, Eman H SalemIndian Journal of Nephrology 2019 29(4):282-287 Hemodialysis (HD) patients are at risk for developing serious infections. Methicillin- resistant Staphylococcus aureus (MRSA) is one of the most prevalent pathogens in healthcare facilities with a major threat to the medical community. We aimed to determine the prevalence of MRSA colonization among patients and medical staff members in a HD Unit and determine efficacy of mupirocin as a decolonizing agent. This cross-sectional study enrolled 250 patients and 35 health care providers of a HD unit. Nasal and hand swabs were...

Methicillin-resistant Staphylococcus aureus (MRSA) is a primarily nosocomial pathogen that, in recent years, has increasingly spread to the general population. The rising prevalence of MRSA in the community implies more frequent introductions in healthcare settings that could jeopardize the effectiveness of infection-control procedures. To investigate the epidemiological dynamics of MRSA...

In this study, we investigated the nature of the cell wall defect in the msaABCR operon mutant in the Mu50 (VISA) and USA300 LAC methicillin-resistant Staphylococcus aureus (MRSA) strains. Results showed that msaABCR-mutant cells had decreased crosslinking in both strains. This defect is typically due to increased murein hydrolase activity and/or nonspecific processing of murein hydrolases mediated by increased protease activity in mutant cells. The defect was enhanced by a decrease in teichoic acid content in the msaABCR mutant. Therefore, we propose that deletion of the msaABCR operon results in decreased peptidoglycan c...
