Phylum Actinobacteria, Class Actinobacteria, Subclass Actibacteridae, Order Actynomycetales, Suborder Corynebacterinae, Family
Corynebacteriaceae, Genus Corynebacterium, Corynebacterium hansenii Renaud, Le Coustumier, Wilhem, Aubel, Riegel, Bollet and
Description is based on a single isolate.
Gram-positive typical club-shaped rods. Non-spore-forming. Non-motile.
After 48 hours incubation, colonies were yellow-pigmented, very small (0.5-1.0 mm),
dry and rough. Grows at 20 & 37 ºC.
Isolated from a severe human thigh liposarcoma infection.
Susceptible amoxicillin, penicillin, imipenem, gentamicin, kanamycin, erythromycin, pristinamycin, rifampicin, vancomycin and
teicoplanin. Resistant to fosfomycin, pefloxacin and tetracycline.
As the strain was isolated together with C. pseudodiphtheriticum and S. aureus, no conclusions can be drawn about its pathogenicity.

nov., an alpha-glucosidase-negative bacterium related to Corynebacterium xerosis. IJSEM 57, 1113-1116.
Most biochemical reactions were determined by API Coryne and API 50CH.
Positive results for catalase, pyrazinamidase, acid production from glucose (at 37ºC; negative at 42 ºC), maltose, ribose & sucrose.
Negative results for alkaline phosphatase, esculin hydrolysis, gelatinase, lipophilism, nitrate reduction, urease, alpha-glucosidase,
beta-glucuronidase, beta-galactosidase & N-acetyl-beta-glucosaminidase, acid production from glycogen, lactose, mannitol & xylose.
Assimilation tests were positive for D-ribose, D-galactose, D-glucose, D-fructose and D-mannose and negative for all other
substrates (D-maltose, D-turanose etc).
