Zygomycosis is an important granulomatous disease that affects humans and animals, particularly sheep in tropical regions. Rhinofacial and nasopharyngeal zygomycosis were described in sheep in association with Conidiobolus spp. The present study characterized 5 samples of Conidiobolus isolated from 3 herds with clinical disease in Mato Grosso State, Brazil. The clinical and pathological findings were similar to nasopharyngeal zygomycosis. Based on morphological features, isolates were classified as Conidiobolus spp., and molecular phylogenetic analyses based on 18S ribosomal DNA grouped all isolates in a Conidiobolus lamprauges cluster. The current report describes the molecular characterization of ovine nasopharyngeal zygomycosis associated with C. lamprauges.

Coronavirus disease 2019 (COVID-19) associated mucormycosis (CAM) was reported predominantly from India during the second wave of COVID-19 and has a high mortality rate. The present study aims to understand the fungal community composition of the nasopharyngeal region of CAM-infected individuals and compare it with severe COVID-19 patients and healthy controls. The fungal community composition was decoded by analyzing the sequence homology of the internal transcribed spacer-2-(ITS-2) region of metagenomic DNA extracted from the upper respiratory samples.

Methods: The nucleic acid amplification test (NAAT) from a nasopharyngeal sample for SARS-CoV-2 was done.
