The nine MRSA isolates were multi-drug resistant (6–9 genes) sequence type (ST) 8, clonal complex (CC) 8, SCCmec type IVa (USA300 clone), and were clonally related (0–16 SNP differences), and carried 16–19 virulence factors. aureus positive (n = 26) nine MRSA and 27 MSSA strains were characterized multiple isolates were chosen from the same sample in two sand and seven coastal beach water samples. Of the 361 samples, 98.1% were positive for Staphylococcus spp. From WGS data, multilocus sequence typing (MLST), SCCmec type, antimicrobial resistance genes, virulence factors, and plasmids were identified. Samples were collected from three regions on Hawaiʻi Island from July to December 2020 during the COVID-19 pandemic and were characterized using whole-genome sequencing (WGS). aureus (MSSA) isolated from coastal beach and river waters, anchialine pools, sand, and wastewater on the island of Hawaiʻi, Hawaiʻi, are a potential health risk. The aim of our study was to determine whether methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-susceptible S. Given that most facilities did not perform active surveillance testing, these are minimum estimates of the national burden of MRSA in US health care facilities.read more read lessĪbstract: Staphylococcus aureus are human facultative pathogenic bacteria and can be found as contaminants in the environment. The majority of MRSA in inpatients appears to be HA-MRSA. Conclusion Our survey documents a much higher MRSA prevalence rate than previous studies using different methodologies. Our data suggest that approximately 70% of isolates were more consistent with health care-associated MRSA (HA-MRSA) than community-associated MRSA. Detailed data were provided on 7994 (92.4%) MRSA-colonized/infected patients. Active MRSA surveillance testing was conducted by 29% of respondents: 54% used routine media, 38% used selective media, and 8% used polymerase chain reaction. inpatients (34 infections and 12 colonizations per 1000 inpatients). Respondents reported 8654 MRSA-colonized/infected patients in 187,058 inpatients the overall MRSA prevalence rate was 46. All states were represented (mean, 23 facilities per state range, 1-99). Complete facility data were provided for 1187 (96%) of these health care facilities. Results Personnel at 1237 hospitals completed the survey. Members were asked to complete the survey on one day during the period October 1 to November 16, 2006, reporting the number of inpatients with MRSA infection or colonization and facility-specific information. The survey was developed, received institutional review board approval, and then distributed to all members of the Association for Professionals in Infection Control and Epidemiology, Inc. Methods We conducted a national prevalence survey of MRSA in inpatients at US health care facilities. Abstract: Background Despite methicillin-resistant Staphylococcus aureus (MRSA) being endemic in virtually all US health care facilities, there are no data on the prevalence of MRSA in US health care facilities.
