Staphylococcus saprophyticus is a uropathogenic bacterium that causes acute uncomplicated urinary tract infections, particularly in female outpatients. We investigated the dissemination and antimicrobial susceptibilities of 101 S. saprophyticus isolates from the genitourinary tracts of patients in Japan. Eight of these isolates were mecA positive and showed beta-lactam resistance. Pulsed-field ...
SCCmec is a mobile genetic element that carries the gene (mecA) mediating methicillin resistance in staphylococci. For Staphylococcus aureus, four SCCmec types have been described, one (type IV) of which has been associated with newly identified community-acquired methicillin-resistant S. aureus. However, the distribution of SCCmec types among S. epidermidis is not known. SCCmec typing of a col...
استافیلوکوکوس اورئوس یکـی از مهمتـرین عوامـل عفونـت هـای بیمارستانی و عفونت های کسب شده از اجتماع است و سویه استافیلوکوک اورئوس مقاوم به متی سیلین mrsa)) مهمترین عامل ایجاد عفونت بیمارستانی است. مقاومت به متی سیلین توسط ژن meca که پروتینی به نام (pbp2a) را کد می کند ایجاد می شود، این ژن در ناحیه ژنومی متحرکی به نام کاست کروموزوم استافیلوکوکی (sccmec) قرار گرفته است. تیپ بندی این منطقه برای درک ...
BACKGROUND Many SCCmec elements of coagulase-negative staphylococci (CoNS) could not be typed using multiplex PCR. Such a 'non-typable' SCCmec was encountered in a Staphylococcus cohnii isolate. METHODOLOGY/PRINCIPAL FINDINGS The SCCmec type of methicillin-resistant S. cohnii clinical isolate WC28 could not be assigned using multiplex PCR. Newly-designed primers were used to amplify ccrA and ...
سابقه و هدف: استافیلوکوکوس اورئوس مقاوم به متی سیلین (methicillin-resistant staphylococcus aureus mrsa) مهمترین عامل ایجاد عفونت بیمارستانی است. هدف از این مطالعه تعیین خصوصیات مولکولی ایزوله های استافیلوکوکوس اورئوس جدا شده از نمونه های بالینی و شناسایی ژن mec و هم چنین تیپ بندی sccmec در بیماران بیمارستان شهید بهشتی کاشان می باشد.مواد و روش ها: این مطالعه توصیفی روی 150 نمونه استافیلوکوکوس او...
Typing of methicillin-resistant Staphylococcus aureus (MRSA) is important in infection control and surveillance. The current nomenclature of MRSA includes the genetic background of the S. aureus strain determined by multilocus sequence typing (MLST) or equivalent methods like spa typing and typing of the mobile genetic element staphylococcal cassette chromosome mec (SCCmec), which carries the m...
BACKGROUND The mecA gene, encoding methicillin resistance in staphylococci, is located on a mobile genetic element called Staphylococcal Cassette Chromosome mec (SCCmec). Horizontal, interspecies transfer of this element could be an important factor in the dissemination of methicillin-resistant S. aureus (MRSA). Previously, we reported the isolation of a closely related methicillin-susceptible ...
Staphylococcal cassette chromosome mec (SCCmec) typing, in combination with genotyping of the Staphylococcus aureus chromosome, has become essential for defining methicillin-resistant S. aureus (MRSA) clones in epidemiological studies. We have developed a convenient system for SCCmec type assignment. The system consists of six multiplex PCRs (M-PCRs) for identifying the ccr gene complex (ccr), ...
BACKGROUND/PURPOSE Methicillin-resistant Staphylococcus aureus (MRSA) typing is an important epidemiologic tool for monitoring trends and preventing outbreaks. However, the efficiency of various MRSA typing methods for each SCCmec MRSA isolate is rarely evaluated. MATERIALS AND METHODS A total of 157 MRSA isolates from four different regions in Taiwan were typed with five different molecular ...
Staphylococcal cassette chromosome mec element (SCCmec) type-dependent clinical outcomes may vary due to geographical variation in the presence of virulence determinants. We compared the microbiological factors and mortality attributed to methicillin-resistant Staphylococcus aureus (MRSA) bacteremia between SCCmec types II/III and type IV. All episodes of MRSA bacteremia in a tertiary-care hosp...
