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% CO
2 atmosphere. Optimum temperature is 37 ºC; variable growth at
42 ºC.

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.
