We have already found some Metarhizium isolates produce euvesperins A and B, which were circumventors of arbekacin resistance in MRSA. These isolates were obtained from soil samples collected from the Izu islands and Kannami town, Sizuoka, Japan. Using a combination of micro-morphological characteristics and multigene (SSU, LSU, TEF) phylogenics, the isolates were identified as a previously underscribed species of Metarhizium. Phylogenetically, the species is close to M. carneum but it is distinguished morphologically from M. carneum by size and the surface structure of conidia.
