Vol. 52.Issue. 3. July - September 2020 | Revista Argentina de Microbiología

ISSN: 0325-7541

Revista Argentina de Microbiología is published by the Asociación Argentina de Microbiología (AAM) on a quarterly basis. The aim of this journal is to publish current scientific works in the different areas of Microbiology and Parasitology. Some of the topics considered of special interest are: infections caused by bacteria, fungi, parasites and viruses; mechanisms of pathogenicity, and virulence factors; resistance to antimicrobial agents; taxonomy; epidemiology and phenotypic, immunologic and molecular diagnostic methods. RAM also publishes articles on microbial ecology and diversity, zoo- and phytopathogens and microorganisms of value for food, agronomic, industrial and environmental applications. With the purpose of covering basic aspects of research in the area, the journal is also interested in the publication of manuscripts on microorganism genomics, proteomics and enzymology, as well as in those articles dealing with regional impact.

Macrolide-lincosamide-streptogramin B resistance phenotypes and their associated genotypes in Staphylococcus aureus isolates from a tertiary level public hospital of Uruguay

Lorena Pardo, Virginia Machado, Dianna Cuello, Paula Aguerrebere, Verónica Seija, Valeria Braga, Gustavo Varela

Rev Argent Microbiol. 2020;52:202-10

Highlights

•
The overall prevalence of MLSB resistance in this set of S. aureus was 38%.
•
The phenotype distribution was: cMLSB, 22%; iMLSB, 10%; MSB, 5% and L, 1%.
•
ermA gene was prevalent in HA-MRSA isolates, mainly in those with a cMLSB phenotype.
•
The combination ermA and ermC genes was prevalent in isolates with inducible resistance.
•
SmaI-PFGE results suggest a great genetic diversity in this MLSB resistant isolates.
