Species description is based on a single isolate.
Gram-positive typically club-shaped rods that occur as single cells, in pairs or in
small clusters. Non-spore-forming. Mycolic acids are present. Tuberculostearic acid
is not present.
Colonies are greenish beige, with irregular edges, up to 2 mm in diameter after 48
hours aerobically incubation on Columbia sheep blood agar at  35 ºC, and express
a characteristic ‘humid cellar’-like odour. Colonies adhere to agar. CAMP test is
negative. Facultatively anaerobic.
Isolated from of a ferret with lethal sepsis. Susceptible to cefotaxime, ciprofloxacin, doxycycline, erythromycin, gentamicin, linezolid,
meropenem, penicillin and vancomycin.
Isolated from various tissues (lung, liver and kidneys) of a ferret with lethal sepsis. It is not known whether transmission of these
corynebacteria to humans occurs.
