Bacteremia caused by Comamonas testosteroni an unusual pathogen

Abstract

Comamonas species are rare isolates in microbiology laboratories and have been infrequently reported as an infectious agent in routine clinical practice. They have a wide range of natural habitats including water, soil, and plants as well as from some hospital devices, such as intravenous lines and the reservoir water in the humidifiers of respiratory therapy equipment. Comamonas testosteroni is rarely recognized as a human pathogen. In spite of its uncommon human pathogenesis, there are few reports where it was reported as an aggressive opportunistic pathogen, and that was mostly related to Testosterone species. Herewith, we are reporting this pathogen from the blood of an immunocompetent female. The aim of this case report is to alert clinicians and laboratory physicians for the potential diagnosis and clinical approach of bloodstream infections caused by such unusual pathogens. This is the first documented case of bacteremia caused by C. testosteroni from India.
