RESUMO

Seven cultures referred to in our laboratories as unidentified gram-negative bacilli or Haemophilus species were identified as atypical strains of Francisella tularensis lacking a requirement for cysteine or enriched medium for growth. The use of cellular fatty acid composition analysis facilitated early recognition of this pathogen and prompt implementation of appropriate biosafety measures.
