Methylobacterium species

An aerobic, gram-negative bacillus producing small, pink to red pigmented colonies that grow poorly on most media. It can be isolated from air, soil, water, sewage, rumen of cows, plants (especially perennial ryegrass, tobacco, soybean) and from the hospital environment. It is capable of causing infections in immunologically compromised patients (bone marrow transplant patients, patients on dialysis, patients with catheters, and patients with cancer).
