Coagulase-negative Staphylococcus (CoNS) species is a leading cause of nosocomial infection in patients with indwelling medical devices and immunocompromised patients. This study was conducted to determine the antibiotic resistance pattern CoNS isolated from major teaching hospital Malaysia. A total 43 isolates were collected August October 2018 at Hospital Canselor Tuanku Muhriz, Kuala Lumpur,...

Staphylococcus aureus staphylococcal cassette chromosome mec type IV (SSCmec IV) is associated with virulent community-acquired methicillin-resistant Staphylococcus aureus (MRSA) and frequent horizontal transfer among staphylococci. To gain insight into the mechanism of transfer, we studied the ccrA/B type 2 recombinase-mediated excision of SCCmec IV (n = 5 strains) and SCCmec II (n = 2). In SC...

Genetic characterization of methicillin-resistant Staphylococcus pseudintermedius (MRSP) from Thailand and Israel revealed the presence of a predominant atypical clonal lineage which was not typeable by SmaI-PFGE and SCCmec typing. All the atypical isolates (n = 34) belonged to CC45 (30 ST45 and 2 ST179 isolates, 1 ST57 isolate, and 1 ST85 isolate). The isolates originated from healthy and dise...

The aim of this study was to identify optimized sets of genotyping targets for the staphylococcal cassette chromosome mec (SCCmec). We analyzed the gene contents of 46 SCCmec variants in order to identify minimal subsets of targets that provide useful resolution. This was achieved by firstly identifying and characterizing each available SCCmec element based on the presence or absence of 34 bina...

Meticillin-resistant Staphylococcus aureus (MRSA) is one of the main causes of hospital-acquired infections, but since late 1990s also the community-acquired. For better understanding of the S.aureus epidemiology there is an urgent need for creation of new typing method for SCCmec element. The molecular typing of MRSA for epidemiological purposes is investigated by pulsed-field gel electrophore...

The cassette chromosome mec (SCCmec) present in methicillin-resistant Staphylococcus aureus (MRSA) has two essential components, the ccr gene complex and the mec gene complex. Additionally, SCCmec has non-essential components called J regions which are used for MRSA subtyping. This study was performed to determine subtypes MRSA strains carrying SCCmec type I based on polymorphism of regions loc...

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 ...

Methicillin-resistant Staphylococcus aureus (MRSA) is a major nosocomial pathogen. We sought to determine the frequency of the different types of SCCmec in MRSA isolates by performing a cross-sectional study. A total of 72 S. aureus isolates were collected from Imam Khomeini and Golestan hospitals and analysed for MRSA and SCCmec typing by multiplex PCR. The pattern of antibiotic resistance amo...

The study was carried out in Polish goat population to estimate the prevalence of nasal cavity infection with various staphylococcal species including methicillin-resistant Staphylococcus aureus(MRSA), investigate potential permissive role small ruminant lentivirus (SRLV) and determine level clonality S. aureus isolates. Nasal swabs blood samples were collec-ted from 1300 clinically healthy adu...

Abstract Staphylococcus aureus is a Gram-positive bacterium, which can cause serious bacterial infections in humans. It constitutes an important etiological factor of many diseases, for instance, soft tissue and skin (including boils abscesses), as well life-threatening necrotizing pneumonia or toxic shock syndrome. estimated that about 25–30% people are carriers S. mainly the anterior nostrils...
