Abstract

Oligella otitidis MSHR-50489EDL strain (ATCC: TSD462; DSMZ: DSM118617) is a new species of the genus Oligella that was isolated from a middle ear discharge swab from a child with chronic suppurative otitis media (CSOM). This Gram-negative coccobacillus produces small, circular, smooth, whitish-opaque and occasionally mucoid colonies. It grows in aerobic conditions at a temperature range from 25-42oC. Phylogenetic analysis demonstrates a relationship to other species of the genera Oligella and average nucleotide identity and digital DNA/DNA hybridization values indicate a distinct species in comparison to other Oligella species. Thus far, the majority of isolates exhibit resistance to ciprofloxacin, the first line treatment for CSOM.
