Dermatophytosis caused by Nannizzia nana.

In this paper, we reported three distinct cases of tinea, including tenia ungulum, tenia pedis, and tenia cruris caused by the infection of Nannizzia nana in the immunocompetent patients who were also the residents of Guatemala. Dermatophytes were identified phenotypically and genotypically. Thereafter, DNA was extracted from the fungal isolates and a fragment of the ITS1-5.

Chromoblastomycosis caused by Rhinocladiella aquaspersa: first case report in Guatemala.

The authors report a case of 40-year-old male patient with a five-year history of chromoblastomycosis on his right leg. Diagnosis was performed by direct 40% KOH exam of skin scales, culture with micro- and macromorphologic analysis, and genotypic characterization (sequencing of a fragment of the ITS region and phylogenetic analysis) of the isolated fungus. Rhinocladiella aquaspersa was identified as the etiological agent.

Onychomycosis due to opportunistic molds.

Background: Onychomycosis are caused by dermatophytes and Candida, but rarely by non- dermatophyte molds. These opportunistic agents are filamentous fungi found as soil and plant pathogens.

Objectives: To determine the frequency of opportunistic molds in onychomycosis.
