Fundamental niche prediction of Cryptococcus neoformans and Cryptococcus gattii in Europe is an important tool to understand where these pathogenic yeasts have a high probability to survive in the environment and therefore to identify the areas with high risk of infection. In this study, occurrence data for C. neoformans and C. gattii were compared by […]

In order to elucidate the distribution of Cryptococcus neoformans and C. gattii in the Mediterranean basin, an extensive environmental survey was carried out during 2012-2015. A total of 302 sites located in 12 countries were sampled, 6436 samples from 3765 trees were collected and 5% of trees were found to be colonized by cryptococcal yeasts. […]

Members of the Cryptococcus species complex (C. neoformans and C. gattii) are opportunistic pathogens responsible for frequently fatal cases of meningoencephalitis. These yeasts have been classified into five serotypes. Serotypes A and D are assigned to C. neoformans var. grubii and C. neoformans var. neoformans, respectively, Serotype AD strains are hybrids and serotype B and […]

Insights on the genotype distribution among Cryptococcus neoformans and C. gattii Portuguese clinical isolates

  • Authors: Inácio J, Maduro AP, Mansinho K, Martins ML, Meyer W, Silva I, Teles F
  • Publication Year: 2014
  • Journal: Current Microbiology
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/24077953

This study provides a comprehensive picture of the C. neoformans/C. gattii molecular types most often associated with human cryptococcosis in Portugal and assesses the impact of C. gattii in these infections. One hundred and twenty-two clinical isolates, from distinct patients, were identified as C. neoformans and genotyped by URA5-RFLP, with the molecular types VNI (45.5 %) and VNIII (30.9 %) being the most commonly found ones.
