Phenotypic switching in Cryptococcus neoformans [PDF]
Microbiology, 2006 Phenotypic switching has been described in serotype A and D strains ofCryptococcus neoformans. It occursin vivoduring chronic infection and is associated with differential gene expression and changes in virulence. The switch involves changes in the polysaccharide capsule and cell wall that affect the yeast's ability to resist phagocytosis. In addition,

Insights Into the Susceptibility of Fungal Infection and STAT3 Genetic Mutations
Mycoses, Volume 69, Issue 7, July 2026.ABSTRACT Signal transducer and activator of transcription 3 (STAT3) is a key transcription factor that regulates a spectrum of genes and signalling pathways critical for the antifungal immune response. Mutations in the STAT3 gene confer susceptibility to severe and recurrent fungal infections, predominantly via disruption of interleukin‐17 (IL‐17 ...

Journal of Clinical Laboratory Analysis, Volume 40, Issue 11, June 2026.Naganishia diffluens, a rare non‐neoformans cryptococcal species, was identified by PCR sequencing as the causative agent of oral cryptococcosis in a 31‐year‐old Iranian man with β‐thalassemia. This case represents the first documented instance of oral infection by N.

A Genomic Catalog of Migratory Microbiomes from Wild Birds across China's Habitats
Advanced Science, Volume 13, Issue 26, 8 May 2026.ABSTRACT Migratory birds play an important role in the spread of antimicrobial resistance (AMR); however, gaps in surveillance data from vital regions along migratory flyways across China limit the detection of emergent threats. Here, we assembled 340 metagenomes from 52 bird species covering 11 provincial administrative districts in China, presenting ...
