Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) in Portugal:

Methicillin-resistant Staphylococcus aureus (MRSA), a human pathogen confined to hospitals (HAMRSA) for over 30 years have been emerging worldwide in the last two decades as a leading cause of severe infections in healthy individuals in the community (CA-MRSA). Despite its clinical significance, in the beginning of our studies no information existed on the prevalence, and population structure of CA-MRSA in Portugal. Moreover, it remained to be clarified how CA-MRSA emerged in our country. In particular, it was not known if CA-MRSA emerged locally by acquisition of the staphylococcal cassette chromosome mec (SCCmec) by established methicillin-susceptible S. aureus (MSSA) in the community, if they were imported from abroad or have escaped from the hospital.(...)

Amidation of peptidoglycan in Staphylococcus aureus

Staphylococcus aureus is one of the most important contemporary human pathogens. The evolutionary “success” of this species is closely related to its remarkably capacity to acquire antibiotic resistance traits. In this perspective, it is important to extend our knowledge concerning the mechanisms of antibiotic resistance in S. aureus and to identify new antimicrobials targets.(...)
