Morphology | Tatumella plyseos |
CELLULAR |
Staining | Gram negative |
Morphology | Small rod-shaped cells 0.6-0.8 x 0.9-3 um |
Motility | Nonmotile at 36`C; over half the strains are motile by means of polar, subpolar or lateral flagella when grown at 25`C |

Growth Parameters | Tatumella plyseos |
PHYSIOLOGICAL |
Tropism | |
Oxygen | Facultatively anaerobic |
pH | |
Temperature | Biochemically more active at 25`C than at 36`C. |
Requirements | |
Products | D- Glucose is fermented with the production of acid but no gas. Few other sugars are fermented at 36`C. |
Enzymes | |
Unique features | . Stock cultures often die within a few weeks on laboratory media. Large zones of inhibition are formed around disks containing penicillin (10 U), in contrast to most other Enterobacteriaceae. |
ENVIRONMENTAL |
Habitat | Isolated from human clinical specimens, mainly from the respiratory tract. |
Lifestyle | |
Pathogenicity | Probably an infrequent opportunistic pathogen (three isolates were from blood) or colonizer. |
