Sternal osteomyelitis by Gordonia Bronchialis in an immunocompetent patient after open heart surgery

Gordonia is a catalase-positive, aerobic, nocardioform, Gram-positive staining actinomycete that also shows weak acid-fast staining. Several Gordonia species are commonly found in the soil. The bacterium has been isolated from the saliva of domesticated/wild dogs as well. In hospitalized patients, most commonly it is found in the setting of intravascular catheter-related infections. However, recent reports show that it is being increasingly isolated from sternal wounds, skin/neoplastic specimens and from pleural effusions. Gordonia shares many common characteristics with Rhodococcus and Nocardia. Ergo, it is commonly misrecognized as Nocardia or Rhodococcus. Since this pathogen requires comprehensive morphological and biochemical testing, it is often difficult and cumbersome to isolate the species. Broad-range Polymerase Chain Reaction (PCR) and sequencing with genes like 16S rRNA or hsp65 are used to correctly identify the species. Identification is essential for choosing and narrowing the right antimicrobial agent. Herein, we report our experience with a patient who presented with sternal osteomyelitis after infection with this elusive bug.
