Metarhizium anisopliae : verticillate and branching conidiophores with cylindrical conidia [lactophenol blue x40]

Metarhizium anisopliae is an entomopathogenic fungus frequently used as a natural pesticide in agriculture. Until now, only a few cases in humans have been reported including a majority of superficial infections (keratitis, sinusitis, cutaneous infections). Keratoplasty was required in almost half of keratitis cases suggesting a particular virulence of this rare fungal pathogen.
