RESUMO
SETTING: Local public health department. DESIGN: Retrospective review of a cluster of three pulmonary Mycobacterium bovis cases occurring in a family, with genotyping of M. bovis strains isolated from the family members. RESULTS: The genotypes of the M. bovis isolates were identical, as determined by three different methods: IS6110 restriction fragment length polymorphism, spoligoytping and mycobacterial interspersed repetitive units-variable number tandem repeat analyses. CONCLUSION: The identification of three acid-fast bacilli (AFB) smear-positive pulmonary M. bovis cases, presenting in a single family and caused by an identical strain, suggests that person-to-person transmission of this organism may have occurred, although infection of one or more family members through ingestion of a contaminated dairy product could not be excluded.

Two unusual cases of Aeromonas infection are described, one associated with bacteremia (Aeromonas schubertii) and another in which the organism was recovered from an infected gall bladder (Aeromonas veronii biotype veronii). These strains were initially identified as Vibrio damsela and Vibrio cholerae by the Vitek and API 20E systems, respectively. Use of appropriate screening tests and familiarity with the newer Aeromonas species could prevent initial misidentifications and potential public health consequences.
