Characterization of Humicola pulvericola First Isolated from a Patient with Keratitis Clinical Case

Figures & data

Figure 1 (A) Obvious conjunctival congestion, with white opacity on the temporal side of the cornea and visible brown foreign body in his right eye; (B) Confocal microscopy revealed abundant hyphae structure at the lesion of the right cornea; (C) Calcofluor white staining of corneal scrapings showed abundant septate hyphae.

Figure 2 (A) The colonies on PDA and SDA after 7 days incubated at 25°C and 35°C; (B and C) Micromorphology examination showed hyphae hyaline and chlamydospores. Chlamydospores produced laterally or intercalary on hyphae, chlamydospores produced laterally or intercalary on hyphae, single-cell, thick-walled, brown, globose to subglobose.

Figure 3 (A) The colonies on PDA and SDA after 14 days incubated at 25°C and 35°C. (B) Micromorphology examination showed two types of conidia: chlamydospores and acremonium-like conidiophores; (C) Acremonium-like conidiophores, which were small (2.5–3 µm × 1.2–1.8 µm), hyaline, aseptate, smooth, obovoid, with slightly truncate ends, arranged in long divergent chains on the apex of the flask shaped conidiogenous cells (phialides).
