Molecular Types of Methicillin-Resistant Staphylococcus aureus and Methicillin-Sensitive S. aureus Strains Causing Skin and Soft Tissue Infections and Nasal Colonization, Identified in Community Health Centers in New York City

Network (CDN) launched a research and learning collaborative project with six community health centers in the New York City metropolitan area to determine the nature (clonal type) of community-acquired Staphylococcus aureus strains causing skin and soft tissue infections (SSTIs). Between November 2011 and March 2013, wound and nasal samples from 129 patients with active SSTIs suspicious for S. aureus were collected and characterized by molecular typing techniques. In 63 of 129 patients, the skin wounds were infected by S. aureus: methicillinresistant S. aureus (MRSA) was recovered from 39 wounds and methicillin-sensitive S. aureus (MSSA) was recovered from 24. Most-46 of the 63-wound isolates belonged to the CC8/Panton-Valentine leukocidin-positive (PVL ؉ ) group of S. aureus clone USA300: 34 of these strains were MRSA and 12 were MSSA. Of the 63 patients with S. aureus infections, 30 were also colonized by S. aureus in the nares: 16 of the colonizing isolates were MRSA, and 14 were MSSA, and the majority of the colonizing isolates belonged to the USA300 clonal group. In most cases (70%), the colonizing isolate belonged to the same clonal type as the strain involved with the infection. In three of the patients, the identity of invasive and colonizing MRSA isolates was further documented by whole-genome sequencing. Staphylococcus aureus is the most common cause of bacterial infections in humans worldwide (1), and methicillin-resistant Staphylococcus aureus (MRSA) is the main cause of skin and soft tissue infections (SSTIs) in North America, with a single clone, USA300, accounting for 98% of these infections (2, 3).The first human case of MRSA infection in the United States was reported in Boston, MA, in 1968 (4). MRSA was first detected in hospitals, and over the following decades, it became the main nosocomial pathogen around the world (5). In 1998, the prevalence of MRSA in 12 hospitals throughout the city of New York was assessed (6), and a single MRSA clone was found to be responsible for an overwhelming majority of MRSA infections. The same MRSA clone was subsequently identified as dominant in MRSA infections in 29 hospitals in the tristate area (7), and it was also identified in MRSA infections in Japan (8). This MRSA clone (multilocus sequence typing [MLST] clonal complex CC5, sequence type ST5, SCCmecII, and unique pulsed-field gel electrophoresis [PFGE] profile)-also known as the "New York/Japan clone" or "MRSA clone USA100"-became the most prevalent MRSA clone involved in MRSA infections in hospitals in the United States in the 1990s (9).In 1993, a new MRSA clone emerged in Kimberley, Western Australia (10), in a community of patients without previous health care contact (community-acquired MRSA [CA-MRSA]). In the late 1990s, CA-MRSA also appeared in the United States and was responsible for the death of four otherwise healthy pediatric patients in Minnesota and North Dakota (11). These new CA-MRSA strains belonged to a clone (USA400/CC1/SCCmecIV)

“…Clade CC8-A also carries the PVL-associated genes and contains isolates that belong to the USA300 clone. In a study investigating the genomics of USA300, Uhlemann et al found evidence for at least five different acquisitions of the lukSF-carrying prophage into the ST8 population, but only a single event into USA300 clone [47]. From their phylogenomic analysis, the authors concluded that acquisition of the lukSF-carrying prophage coincided with the acquisition of ACME and occurred between 1970 and 1993, resulting in the emergence of USA300.…”

The phylum Firmicutes is one of the most abundant groups of prokaryotes in the microbiota of humans and animals and includes genera of outstanding relevance in biomedicine, health care, and industry. Antimicrobial drug resistance is now considered a global health security challenge of the 21st century, and this heterogeneous group of microorganisms represents a significant part of this public health issue.
