Aspergillus hubkae, a Novel Species Isolated from a Patient with Probable Invasive Pulmonary Aspergillosis.

A 50-year-old man, previously diagnosed with pulmonary tuberculosis and lung cavities, presented with symptoms including fever, shortness of breath, and cough. A pulmonary CT scan revealed multiple cavities, consolidation and tree-in-bud in the upper lungs. Further investigation through direct examination of bronchoalveolar lavage fluid showed septate hyphae with dichotomous acute branching.

Prevalence of asymptomatic strongyloidiasis co-infection in COVID-19 patients residing in endemic areas.

Background: Fatal forms of strongyloidiasis, hyperinfection syndrome (HS) and disseminated strongyloidiasis (DS), are caused by exaggerated autoinfection of the intestinal nematode, Strongyloides stercoralis (S. stercoralis). Corticosteroids, frequently administered to patients with severe COVID-19, can transform chronic asymptomatic strongyloidiasis into the above-mentioned fatal diseases.

Identification and genetic diversity of species recovered from the air of Ahvaz city, the Southwestern part of Iran.

The genus has pathogenic, endophytic, and saprobic characteristics. Alternaria genus causes respiratory diseases, fungal allergenicity and the production of mycotoxin in food. Ahvaz city is one of the areas where the presence of dust and high humidity cause the growth and spread of fungal species in the air.
