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.
