Description is based on a single isolate.
Gram-positive, motile (peritrichous flagella) rods, 0.5 x 2.0 μm. Produce ellipsoidal
spore in swollen sporangium.
Grows on routine media. Colonies are greysh, shiny, translucent and 1 mm in
diameter after 24 hours at 30 ºC. Nonhemolytic. Aerobic and anaerobic growth.
Optimum growth temperature 30-37 ºC. Can grow at 50 ºC. Grow in 2%, but not in 5 or
7% NaCl.
The type strain was isolated from human blood culture sample.
Sensitive to amoxicillin, gentamicin, doxycycline,  vancomycin. Resistant to erythromycin, trimethoprim sulfamethoxazole.
The type strain was isolated from blood culture samples of a apyretic 75-year-old woman suffering from chronic interstitial
nephropathy with loose cough and sputum.
