DOI: 10.1016/j.mimet.2020.105981
Abstract: The diagnosis of histoplasmosis depends on various approaches: direct clinical examination, fungus isolation from cultures of clinical samples, histopathological evaluation, and serological testing. In serodiagnostic assays, the Histoplasma capsulatum H and M antigenic glycoproteins have… read more here.

DOI: 10.1080/21505594.2022.2137987
Abstract: ABSTRACT Histoplasmosis is a systemic mycosis caused by the thermally dimorphic fungus Histoplasma capsulatum. Although healthy individuals can develop histoplasmosis, the disease is particularly life-threatening in immunocompromised patients, with a wide range of clinical manifestations… read more here.

DOI: 10.1093/femsec/fiae152
Abstract: Abstract Microbial soil habitats are characterized by rapid shifts in substrate and nutrient availabilities, as well as chemical and physical parameters. One such parameter that can vary in soil is oxygen; thus, microbial survival is… read more here.

DOI: 10.1093/mmy/myae126
Abstract: Abstract Cryptococcus neoformans/gattii and Histoplasma capsulatum var. capsulatum may present atypical histopathological features inducing diagnostic errors. We aimed to estimate the frequency of these atypical features in formalin-fixed tissue (FT) samples and to assess the… read more here.
