RESUMO

Seventeen strains of fastidious, nonoxidative, gram-negative rods, isolated from human wounds resulting primarily from dog or cat bites, formed a distinct group, which was designated Centers for Disease Control (CDC) group nonoxidizer 1 (NO-1). The phenotypic characteristics of CDC group NO-1 were most similar to non-acid-producing Acinetobacter species, with the major difference being a negative reaction in the transformation assay test for Acinetobacter spp. The cellular fatty acid composition of CDC group NO-1 was different from those of Acinetobacter species and all other bacteria tested to date. The isolates were susceptible to a variety of antimicrobial agents including the aminoglycosides, beta-lactam antibiotics, tetracyclines, quinolones, and sulfonamides. Fifty percent of the isolates were resistant to trimethoprim. Ubiquinone-8 was present as the major isoprenoid quinone in CDC group NO-1.
