Several types of infections of the central nervous system by melanized fungi can be distinguished: (a) single-organ infection of the cerebrum, (b) extension into the cerebrum from adjacent cavities, (c) fungal presence in the cerebrospinal fluid, or (d) meningitis. The fungal order Chaetothyriales (containing Exophiala-like black yeasts and relatives) is particularly rich in fungi causing cerebral infections. Cases by the main agents, Cladophialophora bantiana, Exophiala dermatitidis, and Ramichloridium mackenziei, published during the last 5 years are reviewed. Most of these infections prove to be fatal. Resection of the lesions in combination with antimycotic therapy may reduce mortality.

Zoonotic infections (swine-human) caused by influenza A viruses (IAVs) have been reported and linked to close contact between these species. Here, we describe eight human IAV variant infections (6 mild and 2 severe cases, including 1 death) detected in Paraná, Brazil, during 2020-2023. Genomes recovered were closely related to Brazilian swIAVs of three major lineages (1 A.

This study investigates how microbiome colonization influences the development of intestinal type 3 immunity in neonates. The results showed that reduced oxygen levels in the small intestine of neonatal rats induced by Saccharomyces boulardii accelerated microbiome colonization and type 3 immunity development, which protected against Salmonella enterica serovar Typhimurium infection. Microbiome maturation increased the abundance of microbiome-encoded bile salt hydrolase (BSH) genes and hyocholic acid (HCA) levels.

Objectives: Periodontitis, the main cause of tooth loss in adults, is a widespread oral disease characterized by chronic inflammation primarily triggered by periodontopathic bacterial infection. Polyphenols are a class of compounds extracted from herbs and diets, characterized by the presence of more than one phenol unit per molecule. Emerging evidence has revealed that polyphenols show significant effectiveness in ameliorating tissue destruction in periodontitis.
