MRSA,

methicillin-resistant Staphylococcus aureus: see staphylococcusstaphylococcus
, any of the pathogenic bacteria, parasitic to humans, that belong to the genus Staphylococcus. The spherical bacterial cells (cocci) typically occur in irregular clusters [Gr. staphyle=bunch of grapes].

Among community-onset infections, overall MRSA infection rates decreased by 41% (p<0.001), and community-onset MSSA infection rates declined by 0.4% (p = 0.93) (Table) (Figure 3).
We identified S23009-2017 as a PVL-negative, t011carrying, MRSA ST398 type V (5C2&5) isolate.
aureus was diagnosed in the nasal flora of 24% (54) participants, out of which 9.3% (21) were MRSA positive and remaining 14.7% (33) were MSSA positive.
Tedavide, antimikrobiyal ajan seciminde, toplumdaki MRSA prevalansi, saglik bakimiyla iliskili risk faktorlerinin bulunup bulunmadigi, klinik tablonun tipi ve agirliginin goz onunde bulundurulmasi onerilmektedir (8).
Importantly, she and her associates recently published another study in which biocidal disinfectants failed to eliminate MRSA from homes and appeared to increase the risk of multidrug resistance (Appl Environ Microbiol, online 22 Sep 2017.
Conclusion: It is concluded that CMRSA is equal in activity as compared to Mueller Hinton agar with cefoxitin disc which requires at least 3 days of sample processing, so CMRSA can be used for the rapid detection of MRSA without utilization of additional sources.
Among the 165 staphylococcus aureus isolates, 53 (32.12%) were MRSA. Highest numbers of isolates were from pus and wound swab and least in blood and body fluids.
Conclusion: Our findings suggest that CA-MRSA could be responsible for the majority of the infections caused by MRSA within the hospital at which the study took place.
The last few decades have seen waves of MRSA outbreaks and therefore it has become one of the most important and common causes of hospital and community-acquired infections.9 Unfortunately, data regarding the prevalence of MRSA in Pakistan is scarce.10 With the lack of resources, such as microbiology laboratories, the unchecked spread of MRSA in developing countries like Pakistan has been devastating.8 MRSA is mainly transmitted through skin-to- skin contact.1 In the Indian subcontinent, with high population density, there is excessive abuse of unregulated antibiotics and its misuse in the livestock and poultry industries.11 This has provided the perfect setting for the development of drug resistance in the community.2
Results: Among all 1283 isolates, 957(74.6%) were confirmed phenotypically as MRSA. Gender wise prevalence showed that males were more affected than females.
We retrospectively determined the minimum inhibitory concentration (MIC) of daptomycin for clinically relevant, non-repetitive 30 MRSA and 20 methicillin-sensitive Staphylococcus aureus (MSSA) isolates randomly selected from 1615 Staphylococcus aureus isolates obtained from pus and wound swab samples (n=6687) submitted to the microbiology laboratory for aerobic culture and sensitivity profiling during January 2011 to December 2011.
