Identification of Anaerobiospirillum succiniciproducens by MALDI-TOF mass spectrometer. A bacteremia in an immunocompetent patient.

Rev Esp Quimioter 2023;36(3): 319-321 319 tions, growth was observed only on Brucella agar as flat translucent colonies with negative catalase and oxidase reactions, confirming the identification of A. succiniproducens by MALDI-TOF MS with a value of 2,10. Identification was confirmed by 16S rRNA sequencing with A. succiniproducens as result with an homology percentage of 88,3%. Antibiotic susceptibility was performed by E-test on Brucella agar in anaerobiosis at 37oC during 48h of incubation. Following the EUCAST (version 8.1, 2018) anaerobic Gram-negative rods and PK-PD cut-off points, the strain was susceptible to amoxicillin/clavulanate, cefuroxime, cefotaxime, imipenem, ertapenem, moxifloxacin and levofloxacin but resistant to penicillin, amoxicillin, clindamycin and metronidazole (Table 1).

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
