Cavitary pulmonary zygomycosis caused by Rhizopus homothallicus

Arunaloke Chakrabarti et al. J Clin Microbiol. 2010 May.

Abstract

We report the first two proven cases of cavitary pulmonary zygomycosis caused by Rhizopus homothallicus. The diagnosis in each case was based on histology, culture of the causal agent, and the nucleotide sequence of the D1/D2 region of the 28S ribosomal DNA.
