Pseudonocardia carboxydivorans in human cerebrospinal fluid: a case report in a patient with traumatic brain injury
BMC Infect Dis. 2017 Jul;17(1):472
BACKGROUND: Members of the genus Pseudonocardia have been widely reported and recovered from several ecosystems, such as soil samples and plant samples. Pseudonocardia bacteria colonize the microbial communities on the integument of fungus gardening ant species. We present the first documented case of Pseudonocardia carboxydivorans isolated in human cerebrospinal fluid (CSF). To the best of our knowledge, this is the first report of an human infection by P. carboxydivorans. CASE PRESENTATION: A patient, who suffered a traumatic brain injury a month before, was admitted to this hospital due to gait alteration and cognitive disturbances. Culture of cerebrospinal fluid showed ramified, not acid-fast, Gram positive bacilli. The bacterium was identified by molecular methods as P. carboxydivorans. CONCLUSION: This is the first documented case of isolating P. carboxydivorans in human CSF in a case of probable meningitis. Further research is needed in order to determine its pathogenic role in human infections.
