Pacemaker-induced endocarditis by Gordonia bronchialis.

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.

ObjetivoLas especies de Gordonia son patógenos humanos oportunistas que causan infecciones secundarias. Presentamos el segundo caso en el mundo de endocarditis causada por Gordonia bronchialis, así como una revisión de todos los casos de endocarditis causados por Gordonia spp.MétodosLa identificación fue realizada mediante espectrometría de masas MALDI-TOF MS, y se confirmó mediante secuenciación del gen 16S rRNA. La susceptibilidad antimicrobiana se realizó mediante tiras reactivas MIC en agar Müller-Hinton suplementado con un 5% de sangre ovina desfibrinada, conforme al Clinical and Laboratory Standards Institute (CLSI).ResultadosLa endocarditis del marcapasos debido a infección por Gordonia bronchialis se encontró en una mujer de 88 años. La paciente fue tratada con ceftriaxona y ciprofloxacina hasta completar el periodo de 6 semanas desde el explante del marcapasos, con buena evolución.ConclusiónEste caso respalda el rol patogénico de Gordonia bronchialis como patógeno oportunista, subrayando el alto riesgo de padecer infecciones causadas por bacterias ambientales.
