Brevundimonas diminuta Infection in a Congenital Atrial Septal Defect Patient: A Case Report

Abstract

Brevundimonas species are aerobic, non fermenting Gram negative bacilli. Brevundimonas diminuta (B. diminuta) is not believed to be a significant pathogen, and its virulence is generally low, being rarely isolated from clinical samples. Only a few clinical cases of serious opportunistic infections, particularly in patients with compromised immunity, have been reported for B. diminuta. All known species of Brevundimonas spp. show strong resistance to most antibiotics, according to the Centers for Disease Control and Prevention (CDC). Here, a case of B. diminuta infection in an eight-year-old female child is described. The patient also had a minor Patent Ductus Arteriosus (PDA) and a known congenital Atrial Septal Defect (ASD). Following isolation from the blood sample, the VITEK 2 compact system identified B. diminuta.
