Phylum Actinobacteria, Class Actinobacteria , Order Micrococcales, Family Micrococcaceae, Genus Arthrobacter, Arthrobacter
gandavensis Storms, Devriese, Coopman, Schumann, Vyncke and Gillis, 2003.
Gram-positive relatively small (0.5-1 µm) coccobacilli with one pointed end. Motile.
Spores are not produced.
Colonies are smooth, glistening, up to 1 mm in diameter. A bright yellow pigment is
produced on Columbia agar with 5% sheep blood at 37 ºC in air. Culture precipitate
(sediment) partially in BHI broth. Obligate aerobic. Grows at 25, 37 and 42 ºC. No
growth in NaCl 6.5%.
Habitat is unknown. Isolated from mammary and uterine infections from cattle.
Isolated from mammary and uterine infections from cattle but its pathogenic role in these processes is uncertain.
