  • Consider also Dermabacter, Cellutomonas, Exlguobactertum, and Mkxobacterium from Table 19-4 If the Isolate Is pigmented, motile, or esculln- or gelatin-positive. The aerotolerant catalase-positive Propionibacterium spp. and Actinomyces spp. included In Table 20-4 should also be considered in the differential with the organisms in this table.
  • Separation of lipophilic and nonlipophilic species can be determined by comparing growth on sheep blood agar and sheep blood agar with 1 % Tween 80 or growth in brain-heart infusion broth with and without 1 drop of Tween 80 or rabbit serum.
  • Reactions from API Coryne.

Propionic acid as an end-product of glucose metabolism.

•CAMP data using a beta-lysin-producing strain of Staphylococcus aureus.

ND, No data; v, variable reactions; +, *90% of species or strains are positive, +", weakly positive; (+), delayed positive reaction; -, *90% of species or strains are negative. ' Most frequently encountered species in human clinical material; frequently mlsidentlfled as C. xerosis. " Sticky colonies.

c Yellow or black-plgmented; btack-plgmented strains have been previously listed as C. nigricans, may be pathogenic from female genital tract. "Yellow after 72 hours.
