Colonies are non-hemolytic, smooth, white, round, approximately 1 mm in diameter
after two days incubation on Tryptic Soy Agar supplemented with 5% sheep blood.
Microaerophilic, no growth was observed in a normal atmosphere. Strains were
incubated in 5% CO2 atmosphere. Optimum temperature is 37 ºC; variable growth at
Phylum Proteobacteria, Class Betaproteobacteria, Order Neisseriales, Family Neisseriaceae, Genus Snodgrasella, Snodgrassella
alvi Kwong and Moran 2013, sp. nov. - type species of the genus.
Gram-negative short rods. Non-motile.
Isolated from the gut of the Western honey bee, Apis mellifera, and the bumble bees Bombus bimaculatus and Bombus vagans.
Susceptible to ampicillin (20 μg / paper disk), carbenicillin (50 μg), ceftazidime (30 μg), chloramphenicol (30 μg), gentamicin (25 μg),
kanamycin (30 μg), nalidixic acid (30 μg), rifampicin (30 μg), spectinomycin (50 μg), streptomycin (10 μg). Variable results for
oxytetracycline (30 μg) and tylosin (30 μg).
Undetermined. Gut-associated bacteria isolated in axenic culture from the honey bee and bumble bees.

Gammaproteobacteria. Int. J. Syst. Evol. Microbiol., 2013, 63, 2008-2018.
Positive results for catalase & nitrate reduction.
Negative results for gelatinase, beta-galactosidase, beta-glucosidase (aesculinase), H2S production, indole production, oxidase, acid
production from glucose. No growth in API AUX medium (bioMerieux) for the API 20NE carbon substrate assimilation tests, but did
use L-arabinose, citric acid, D-fructose, D-galactose, D-glucose, L-glutamine, glycerol, glycine, DL-malic acid, maltose, D-mannitol,
D-mannose or succinic acid in suplemented M9 agar (see the original paper by Kwong).
Variable results for arginine dihydrolase & urease.
