Here, we investigated the molecular types of 57 cryptococcal isolates from patients in a tertiary care hospital in the state of Amazonas, Brazil, between 2006 and 2010. The isolates were characterised by PCR fingerprinting using the M13 minisatellite and confirmed by <jats:italic>URA5<\/jats:italic>\u2010RFLP analysis, and the presence of specific genes from the mating type locus (MAT\u03b1 and MATa) of these species was analysed by PCR. Most of the patients were male (66.7%), between 16 and 30\u2003years of age (51.7%), and HIV\u2010positive (75.0%). Most isolates were collected from cerebrospinal fluid samples (71.7%). Most of the <jats:italic>C. neoformans<\/jats:italic> isolates (<jats:italic>n\u2003<\/jats:italic>=\u200340) were characterised as members of the VNI molecular group (<jats:italic>n\u2003<\/jats:italic>=\u200339), a unique isolate was characterised as VNII whereas all isolates of <jats:italic>C. gattii<\/jats:italic> (<jats:italic>n\u2003<\/jats:italic>=\u200317) were members of the VGII molecular group. With regard to mating types, 55 isolates were type \u2018\u03b1\u2019, and only two were type \u2018a\u2019. This study revealed the prevalence of the VNI molecular group and provides the first reported observation of the VNII molecular group in the northern region of Brazil.<\/jats:p>","DOI":"10.1111\/j.1439-0507.2012.02173.x","type":"journal-article","created":{"date-parts":[[2012,2,24]],"date-time":"2012-02-24T11:18:54Z","timestamp":1330082334000},"source":"Crossref","is-referenced-by-count":31,"title":["Molecular
