[Multilocus sequence typing of methicillin-resistant Staphylococcus aureus].
OBJECTIVE To analyze multilocus sequence typing (MLST) of methicillin-resistant Staphylococcus aureus (MRSA) strains in 2000 and 2005, and get a primary knowledge of MLST Characterization of MRSA. METHODS Sequence analysis was conducted on seven allelic genes of 29 methicillin-resistant Staphylococcus aureus strains and 2 methicillin-sensitive Staphylococcus aureus (MSSA) strains and the alle...
متن کاملMultilocus sequence typing for characterization of methicillin-resistant and methicillin-susceptible clones of Staphylococcus aureus.
A multilocus sequence typing (MLST) scheme has been developed for Staphylococcus aureus. The sequences of internal fragments of seven housekeeping genes were obtained for 155 S. aureus isolates from patients with community-acquired and hospital-acquired invasive disease in the Oxford, United Kingdom, area. Fifty-three different allelic profiles were identified, and 17 of these were represented ...
متن کاملThe Evolution of Methicillin-resistant Staphylococcus aureus
Since 1961, methicillin-resistant Staphylococcus aureus (MRSA) has evolved through both single locus gene variation and horizontal gene transfer. By the late 1970s, the emergence of new SCCmec allotypes marked the beginning of a worldwide MRSA pandemic. The continuous and rapid evolution of MRSA, in response to new antibiotics, remains a major public health issue worldwide.
متن کاملMultilocus sequence typing of intercontinental bovine Staphylococcus aureus isolates.
A total of 258 bovine-associated Staphylococcus aureus isolates from the United States, Chile, and the United Kingdom, plus the reference isolate S. aureus Newbould 305 (NCIMB 702892), were analyzed by multilocus sequence typing (MLST). A collection of previously characterized United Kingdom isolates were also included in the analysis. The results demonstrated that MLST is suitable for the diff...
متن کاملMultilocus sequence typing of Staphylococcus aureus with DNA array technology.
A newly developed oligonucleotide array suited for multilocus sequence typing (MLST) of Staphylococcus aureus strains was analyzed with two strain collections in a two-center study. MLST allele identification for the first strain collection fully agreed with conventional strain typing. Analysis of strains from the second collection revealed that chip-defined MLST was concordant with conventiona...
