Conclusions: We present the most detailed genomic analysis of MRSA isolated in Sri Lanka to date. The analysis identified a PVL-positive ST5-MRSA-IVc that is prevalent among MRSA causing clinical infections in Sri Lanka. Furthermore, this clone was also found among isolates from the United Kingdom and Australia. Introduction Worldwide, Staphylococcus aureus is the primary causative agent of community-acquired skin and soft tissue infections (SSTI) and is an important cause of hospital-associated invasive infections including bacteremia, pneumonia and endocarditis (Bell et al., 2002; David and Daum, 2010). Panton-Va...

This study identified prophages as mediators of bacterial virulence in a model of infectious endocarditis, probably through promotion of interaction with extracellular matrix components. Further studies are needed to identify mechanisms leading to promotion of intrinsic virulence. Introduction Challenges related to Staphylococcus aureus infections in the human and veterinary clinics mobilized important human and technical resources. S. aureus can colonize 20–30% of the general population asymptomatically but is also capable of causing a wide spectrum of diseases ranging from benign infections, to particularly...

ConclusionThe decline in MRSA BSI rates observed in our institution was associated with changes in population structure of the organism. This decline may be related to biological properties of the prevailing MRSA clones.

indrachuk Influenza viruses are a threat to global public health resulting in ~500,000 deaths each year. Despite an intensive vaccination program, influenza infections remain a recurrent, yet unsolved public health problem. Secondary bacterial infections frequently complicate influenza infections during seasonal outbreaks and pandemics, resulting in increased morbidity and mortality. Staphylococcus aureus, including methicillin-resistant S. aureus (MRSA), is frequently associated with these co-infections, including the 2009 influenza pandemic. Damage to alveolar epithelium is a major contributor to severe influenza-bac...

Over the past 20 years there have been two dominant pandemic healthcare-associated methicillin-resistant Staphylococcus aureus (HA-MRSA) clones in the UK, EMRSA –15 (ST22) and EMRSA-16 (ST36), with lower prevalence of other clones (ST8, ST239, ST5 and ST247). HA-MRSA rates have decreased significantly since the mid-2000s1–4 following the introduction of a comprehensive UK-wide infection control program comprising re-enforcement of basic infection contro l practices and targeted measures of screening, contact precautions, patient isolation and decolonization.

Discussion: The genomic diversity of Gaza ST22 isolates is not consistent with recent emergence in the region. The results indicate that two divergent Gaza clones evolved separately from susceptible isolates. Researchers should not assume that isolates identified as ST22 in the community are examples of EMRSA-15 that have escaped their healthcare roots. Future surveillance of MRSA is essential to the understanding of ST22 evolutionary dynamics and to aid efforts to slow the further spread of this lineage. PMID: 30153881 [PubMed - in process]

Authors: Tfifha M, Ferjani A, Mallouli M, Mlika N, Abroug S, Boukadida J Abstract The pandemic spread of multidrug-resistant (MDR) bacteria (i.e., methicillin-resistant Staphylococcus aureus (MRSA), extended-spectrum b-lactamase-producing Enterobacteriaceae (ESBLPE), vancomycin-resistant enterococci, carbapenemase-producing Enterobacteriaceae (CPE), multiresistant Pseudomonas aeruginosa and multiresistant Acinetobacter baumannii) pose a threat to healthcare Worldwide. We found limited data of MDR bacteria in pediatric patients hospitalized in Tunisian tertiary healthcare.The aim of the study is to evaluate the acqu...

USA300 is a pandemic clonal lineage of hypervirulent, community-acquired, methicillin-resistant Staphylococcus aureus (CA-MRSA) with specific molecular characteristics. Despite its high clinical relevance, the evolutionary origin of USA300 remained unclear. We used comparative genomics of 224 temporal and spatial diverse S. aureus isolates of multilocus sequence type (ST) 8 to reconstruct...
