Purpose: Gordonia species are known to be opportunistic human pathogens causing secondary infections. We present the second case in the world of endocarditis caused by Gordonia bronchialis and a review of all the cases of endocarditis caused by Gordonia spp.
Methods: The identification was performed by matrix-assisted desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) and 16S rRNA gene sequencing were performed to confirm the identification. Antimicrobial susceptibility was performed by MIC test Strip on Mueller-Hinton agar supplemented with 5% defibrinated sheep blood according to Clinical and Laboratory Standards Institute.
Results: Pacemaker-induced endocarditis due to Gordonia bronchialis infection was determined in an 88-year old woman. The patient was treated with ceftriaxone and ciprofloxacin until completing 6 weeks from the pacemaker explant with a good evolution.
Conclusion: The case presented supports the pathogenic role of Gordonia bronchialis as an opportunistic pathogen and highlights the high risk of suffering infections caused by environmental bacteria.

Background: Corynebacterium, Nocardia, Rhodococcus, Mycobacterium, as well as Gordonia genera belongs to the genus Gordonia, Actinomycetia class. is a nitrate-reducing, urease-producing, non-motile, force aerobe with a rod-like figure that is known to arrangement into sessile, cord-like groups. This systematic review aimed to establish whether and what invasive infections in humans were caused by , and to evaluate outcomes of administered antibiotic treatment.

Gordonia bronchialis is an aerobic gram-positive bacilli and also weakly acid fast. It requires a long incubation time and extensive biochemical reactions for identification. Therefore, use of broad-range polymerase chain reaction (PCR) for amplification of genes such as 16S rRNA or hsp65 followed by sequencing or advanced techniques like MALDI-TOF MS is needed for identification.

The immunosuppression conditions and the presence of medical devices in patients favor the infections. However, the features of this aerobic actinomycete have been little explored. Strains ( = 164) were characterized with 16S rDNA and A1 genes to define their phylogenetic relationships, and subjected to broth microdilution to profile the antimicrobial susceptibilities of species that caused infections in Spain during the 2005-2021 period.
