Rev Argent Microbiol. 2020;52:183-8

  • This is the first multicentre study of cryptococcosis around the country.

  • The study shows the geographical distribution of genotypes and mating types.

  • The study reveals the presence of uncommon hybrids.

  • The study reveals regions with high frequencies of some genotypes.

  • The study highlights the necessity of more regional studies.

  • 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.

  • Lag phases prior to growth were higher in media with GP than in media without it.

  • The growth rate of most of the isolates was greater in media supplied with GP.

  • The highest EC50 (>100mM) was found for Trichoderma spp.

  • Sterilia spp. had EC50 values of 100mM.

  • Aspergillus spp. and Mucor spp. had EC50 values between 50 and 100mM.
