Gram-stain morphologic features, motility, and flagellar placement are important identifying characteristics of:
a. Chryseobacterium.
b. Flavobacterium.
c. Pseudomonas.
d. Bordetella.
D
The ability of most commercial identification systems to identify accurately the organisms dis-cussed in this chapter is limited or uncertain. Therefore the strategies for identifying these genera are based on the use of conventional biochemical tests and special staining for flagella. Organ-isms are first divided on the basis of Gram-stain morphologic features, that is, their coccoid or rod shape. They are then further divided on the basis of whether the organisms are nonmotile, peritrichously flagellated, or flagellated by polar tufts.
