Phylum Firmicutes, Class Bacilli, Order Bacillales, Family Paenibacillaceae, Genus paenibacillus, Paenibacillus timonensis Roux
and Raoult 2004.
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
The type strain was isolated from human blood culture sample.
Sensitive to amoxicillin, gentamicin, doxycycline, and vancomycin. Resistant to erythromycin and 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.
