Further biochemical
tests indicated that all isolated strains were Gram-negative,
catalase-positive, oxidase-negative, and showed no motility. A
total of twelve different colonies were analyzed, and the results
obtained are shown in Table 2. Identified colonies included
three Enterobacter agglomerans, two Enterobacter cloacae, three
Morganella morganii colonies, and four other unidentified
colonies.
