Seventy-one percent of 76 methicillin-resistant Staphylococcus aureus (MRSA) strains isolated from two medical centers in El Paso, Texas, represent three similar pulsed-field gel electrophoresis types. Overall, six pulsed-field types were identified represented by multilocus sequence/staphylococcal chromosomal cassette DNA mec (SCCmec) types: ST5-MRSA-II; ST36-MRSA-II; ST8 (untypeable SCCmec); ...

conclusions carrier samples screening is considered inferior to clinical samples. treatment of a variety of infectious diseases is difficult due to resistant bacteria. consequently, annual screening of these individuals, detecting the carriers and decolonizing them to reduce transmission of s. aureus in the hospital are necessary. background methicillin-resistant staphylococcus aureus (mrsa) is...

To the Editor: Van Loo et al. described the presence of staphylococcal cassette chromosome mec (SCCmec) type III in some methicillin-resistant Staphylococcus aureus sequence type (ST) 398 isolates related to pig farming (1). SCCmec types are based on the allotype of ccr genes and the mec gene complex. Class A mec has intact mecI/R regulator genes. Type III SCCmec has type 3 ccr genes and class ...

OBJECTIVES Methicillin-resistant staphylococci (MRS) isolates from healthy and diseased cats and dogs were characterized by staphylococcal cassette chromosome mec (SCCmec), multilocus sequence typing (MLST) and cassette chromosome recombinase gene (ccrAB) sequencing. METHODS PCR-directed SCCmec typing was carried out for all MRS isolates and two Staphylococcus aureus and two Staphylococcus ep...

Staphylococcus aureus is an ubiquitous bacterium that is frequently part of the human microflora, causing disease when the immune system becomes compromized. Although S. aureus can be found in different parts of the body, anterior nares are the main ecological reservoir in humans [1]. This versatile pathogen is responsible for a wide variety of diseases, including superficial, systemic and life...

Abstract Introduction To understand the prevalence of avian methicillin-resistant Staphylococcus aureus (MRSA) and current status drug resistance in Qingdao, a comprehensive molecular epidemiological investigation analysis evolutionary relationships MRSA isolates from broiler layer chickens waterfowl was conducted. Material Methods One hundred two strains were identified by multi-locus sequence...

Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) is a growing public health concern that has been associated with pediatric fatalities. It is hypothesized that the evolution of CA-MRSA is a recent event due to the acquisition of mec DNA by previously methicillin-susceptible strains that circulated in the community. This study investigated the genetic relatedness between ...
