“Background Accurate identification of fastidious Gram-negative rods (GNR) Mocetinostat is a challenge for clinical microbiology laboratories. Fastidious GNR are slow-growing organisms, which generally require supplemented media or CO2 enriched atmosphere and fail to grow on enteric media such as MacConkey agar [1]. They are isolated infrequently and consist of different taxa including Actinobacillus, Capnocytophaga, Farnesyltransferase Cardiobacterium, Eikenella, Kingella, Moraxella, Neisseria, and Pasteurella. Most of them are colonizers of the human oral cavity but they have been demonstrated to cause severe systemic infections like endocarditis, septicemia and abscesses, particularly in immunocompromised patients [1, 2]. Accurate identification of fastidious GNR is of concern when isolated from normally sterile body sites regarding guidance of appropriate

antimicrobial therapy and patient management [1]. Identification of fastidious GNR by conventional methods is difficult and time-consuming because phenotypic characteristics such as growth factor requirements, fermentation and assimilation of carbohydrates, morphology, and staining behaviour are subject to variation and dependent on individual interpretation and expertise [1, 3]. Commercially available identification systems such as VITEK 2 NH (bioMérieux, Marcy L’Etoile, France) only partially allow for accurate identification of this group of microorganisms, e.g., Eikenella corrodens, Kingella kingae and Cardiobacterium hominis[4–6]. Most studies relied only on a subset of taxa of fastidious GNR or did not include clinical isolates under routine conditions [4–6].
