ABSTRACT Livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) is a bacterium carried by or obtained from swine and other livestock. The initial and predominant swine-associated LA-MRSA sequence type (ST) identified is ST398. Here, we present 14 draft genome sequences from LA-MRSA ST398 isolates found in the United States.

ABSTRACT Methicillin-resistant Staphylococcus aureus colonizes humans and other animals such as swine. Livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) sequence type 5 (ST5) isolates are a public concern due to their pathogenicity and ability to acquire mobile genetic elements. This report presents draft genome sequences for 63 LA-MRSA ST5 isolates in the United States.

Here, we report the draft genome sequences of eight community-associated methicillin-resistant Staphylococcus aureus strains that were resistant to cefoxitin, ampicillin, and erythromycin. Three isolates, i.e., CAR1, CAR2, and CAR8, were sequence type 8 (ST8) with staphylococcal cassette chromosome mec (SCC mec ) type IVa and were Panton-Valentine leukocidin (PVL) positive, which has been known as a predominant clone in the United States.

ABSTRACT Staphylococcus aureus is a commensal bacterium of humans that can cause a spectrum of diseases. An isolate’s capacity to cause disease is partially attributed to the acquisition of novel mobile genetic elements. This report provides the draft genome sequence of one methicillin-susceptible and seven methicillin-resistant clinical human S. aureus isolates.

ABSTRACT We report here the draft genome sequences of two community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) strains, C18 and C80, isolated from healthy children from day care centers. To our knowledge, these are the first draft genome sequences of CA-MRSA ST398/CC398/SccmecV and CA-MRSA ST5/CC5/SccmecIVa isolated from healthy children in Brazil.

ABSTRACT Methicillin-resistant Staphylococcus aureus (MRSA) colonizes and causes disease in many animal species. Livestock-associated MRSA (LA-MRSA) isolates are represented by isolates of the sequence type 398 (ST398). These isolates are considered to be livestock adapted. This report provides the complete genome sequence of one swine-associated LA-MRSA ST398 isolate from the United States.

ABSTRACT Humans have been found to harbor livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) isolates. LA-MRSA isolates are considered adapted to colonizing livestock and less pathogenic in humans than their hospital- and community-acquired counterparts. Here, we present nine LA-MRSA sequence type 5 isolates from veterinarians with long-term swine contact.

ABSTRACT Livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) sequence type 5 (ST5) has raised concerns surrounding the potential for these isolates to colonize or cause disease in humans with swine contact. Here, we report draft genome sequences for nine LA-MRSA ST5 isolates obtained from humans after short term swine contact.

ABSTRACT Methicillin-resistant Staphylococcus aureus (MRSA) can be a commensal or pathogen in humans. Pathogenicity and disease are related to the acquisition of mobile genetic elements encoding virulence and antimicrobial resistance genes. Here, we report draft genome sequences for 50 clinical MRSA isolates from humans with MRSA-related disease.

ABSTRACT Methicillin-resistant Staphylococcus aureus (MRSA) sequence type 630 (ST630) and spa type t4549 is an emerging lineage in Nordic countries, and some representatives carry the CRISPR-Cas system. Here, the complete genome sequences of two isolates from this lineage are presented, comprising chromosomes of 2,918,239 and 2,877,083 nucleotides, respectively, and a 2,473-nucleotide plasmid carrying erm(C).

ABSTRACTTelavancin had MIC50, MIC90, and MIC100values of 0.03, 0.06, and 0.12 μg/ml, respectively, against methicillin-susceptibleStaphylococcus aureus, methicillin-resistantS. aureus(MRSA), and non-multidrug-resistant (non-MDR) and MDR subsets. MRSA with elevated MIC values for vancomycin (2 to 4 μg/ml) or daptomycin (1 to 2 μg/ml) had telavancin MIC50(0.06 μg/ml) values 2-fold higher than those of isolates with lower MIC results (MIC50, 0.03 μg/ml). However, telavancin had MIC90and MIC100results of 0.06 and 0.12 μg/ml (100% susceptible), respectively, regardless of the MRSA subset.
