Prospecting Biomarkers for Diagnostic and Therapeutic Approaches in Pythiosis.

Pythiosis, whose etiological agent is the oomycete , is a life-threatening disease that occurs mainly in tropical and subtropical countries, affecting several animal species. It is frequently found in horses in Brazil and humans in Thailand. The disease is difficult to diagnose because the pathogen's hyphae are often misdiagnosed as mucoromycete fungi in histological sections.

Molecular detection of Histoplasma capsulatum in bats of the Amazon biome in Pará state, Brazil.

Histoplasma capsulatum, the fungus causing histoplasmosis, has a strong impact on public health. Histoplasmosis is one of the most prevalent systemic mycoses in the Americas and occurs in several mammalian species. Bats are important in the epidemiological cycle of histoplasmosis because they disseminate the fungus throughout the environment.

Rabies virus and Histoplasma suramericanum coinfection in a bat from southeastern Brazil.

Bats are essential to the global ecosystem, but their ability to harbour a range of pathogens has been widely discussed, as well as their role in the emergence and re-emergence of infectious diseases. This paper describes the first report of coinfection by two zoonotic agents, rabies virus (RABV) and the fungus Histoplasma suramericanum in a bat. The bat was from the Molossus molossus species, and it was found during the daytime in the hallway of a public psychiatric hospital in a municipality in São Paulo State, southeastern Brazil.

Infection by Histoplasma capsulatum, Cryptococcus spp. and Paracoccidioides brasiliensis in bats collected in urban areas.

Epidemiological studies on endemic mycosis can be improved using molecular biology techniques to elucidate the role of bats as reservoirs and vectors of pathogenic fungi for infection of other animals and humans. The objective of this study was to explore the presence of Histoplasma capsulatum, Cryptococcus spp. and Paracoccidioides brasiliensis in insectivorous, frugivorous and nectarivorous bats collected in urban areas.
