Methylobacterium mesophilicum

A slow-growing gram-negative bacterium found on soil, vegetation, and tap water in hospitals. It is not part of the normal human flora, but is pathogenetic in immunocompromised hosts; it may cause bacteraemia and peritonitis in patients on chronic ambulatory peritoneal dialysis.

Similarly, when comparing samples with similar initial loads ([n.sub.0]), microorganisms with a shorter doubling time ([t.sub.D]) such as Pseudomonas aeruginosa (for which [t.sub.D] = 1 hr 40) have a shorter TTD compared to microorganisms with a longer doubling time, such as Methylobacterium mesophilicum (for which [t.sub.D] = 8 hrs (41)).

There have been documented cases of respiratory infections caused by Mycobacterium chelonae and Methylobacterium mesophilicum (Kressel 2001) as well as a number of reported cases of antimicrobial-resistant Pseudomonas aeuroginosa (CDC 1991, Sorin et al 2001, Weber & Rutala 2001) and recorded transmissions of Mycobacterium tuberculosis (Weber & Rutala 2001) and Meticillin resistant Staphylococcus aureus (MRSA).
