Abstract

We report 2 cases of pulmonary Bordetella hinzii infection in immunodeficient patients. One of these rare cases demonstrated the potential transmission of the bacteria from an avian reservoir through occupational exposure and its persistence in humans. We establish bacteriologic management of these infections and suggest therapeutic options if needed.

Highlights

  • We report 2 cases of pulmonary Bordetella hinzii infection in immunodeficient patients

  • B. hinzii is found in the respiratory tract of poultry

  • It was initially described as a commensal bacterium in birds, some veterinary isolates appear to have pathogenic properties: Register et al reported that it is associated with tracheal lesions in turkeys [1,6]

Summary

Opportunistic Pulmonary Bordetella hinzii Infection after Avian Exposure

We report 2 cases of pulmonary Bordetella hinzii infection in immunodeficient patients. One of these rare cases demonstrated the potential transmission of the bacteria from an avian reservoir through occupational exposure and its persistence in humans. We establish bacteriologic management of these infections and suggest therapeutic options if needed. Bordetella hinzii bacteria cause respiratory infections in birds and have been isolated from rodents on rare occasions [1,2]. B. hinzii can persist for >1 years in the respiratory tract of humans [5], but its transmission from birds has not been proven. We suggest how to manage these infections in humans, pathogenicity of this bacterium remains unclear
