Identification of "Haematobacter," a new genus of aerobic Gram-negative rods isolated from clinical specimens, and reclassification of Rhodobacter massiliensis as "Haematobacter massiliensis comb. nov.".

ABSTRACT: Twelve strains of gram-negative, nonfermenting rods recovered mainly from septicemic patients were studied using conventional and molecular methods. The phenotypic profiles of these strains most closely resembled Psychrobacter phenylpyruvicus. They produced catalase, oxidase, urease, and H(2)S (lead acetate paper) but did not produce indole, reduce nitrate or nitrite, or hydrolyze gelatin or esculin. No acid production was observed in a King's oxidation-fermentation base containing d-glucose, d-xylose, d-mannitol, sucrose, lactose, or maltose. All strains were nonmotile and nonpigmented. Most strains produced green discoloration on blood agar. All strains grew at 25 degrees C and 35 degrees C and most grew on MacConkey agar. They shared a common cellular fatty acid (CFA) profile characteri
