The fungus from 1 specimen (ie, patient 4) that failed to grow in culture was identified by broad-range fungal PCR and DNA sequencing as Rhizopus oryzae. Although this application was arguably the most appropriate use of molecular diagnostics in this study, both the histopathologic evaluation and the direct examination demonstrated mucoraceous hyphae (ie, broad, pauciseptate hyphae), and these results were present long before the results from the molecular studies (ie, 1-2 days after surgery versus approximately 1 week).

[8] The most common infections caused by Zygomycetes include those caused by members of the four genera Rhizopus, Rhizomucor, Absidia, and Mucor, with Rhizopus oryzae being the species most frequently isolated from patients, [9] whereas Rhizopus stolonifer has never been implicated in a human infection.
