According to Kampfer and Glaeser 2015 Serratia glossinae Geiger et al. 2010 is a later synonym of Serratia fonticola.
Gram-negative, straight rods, 0.5-0.8 x 0.9-2.0 μm, non-sporulated. Some strains are
capsulated. Motile by peritrichous flagella.
Colonies are 1 to 3 mm in diameter, circular, shiny, opaque, cream-white and smooth
with an entire margin. Prodigiosin is not produced. Facultatively anaerobic, growth
temperature 20-35 ºC (range may vary from 10 to 40 ºC). Doesn't require growth
factors.
Isolated from water.
S. glossinae was isolated from the midgut of the tsetse fly Glossina palpalis gambiensis.
Undetermined.

S. glossinae DSM 22080T strain produce urease and very weakly acetoin.

Positive results for catalase (S. fonticola strain DSM 4576T is negative), ONPG, esculin hydrolysis, citrate utilization, acid production
from fructose, glucose, mannitol, glycerol, maltose, D-mannose, ribose, salicin and trehalose.

Negative results for oxidase, indole production, H2S production, phenylalanine deaminase and acid production from mucate.
