One hundred and sixty-two cultures of Alcaligenes species (A. denitrificans, A. faecalis, and A. odorans) of clinical origin were characterized by routine diagnostic and carbon substrate utilization techniques. Colonial morphology was a valuable distinguishing char-acteristic between Alcaligenes reference strains and avian Alcaligenes-like isolates. Catalase- and oxidase-positive. Int J Syst Bacteriol 30: 225-420, 1980. Journal of Infectious Diseases, 1928, 43, 330-334. The field isolates and type strains Alcaligenes faecalis NCTC 415 and Bordetella bronchi-septica NCTC 452 were characterised by biochemical tests, but these did not include any electrophoresis or nucleic acid studies.
