Mycobacterium phlei Vertebral Osteomyelitis

Disseminated Mycobacterium chimaera Presenting as Vertebral Osteomyelitis

Mycobacterium chimaera, a member of the Mycobacterium avium complex, is a slow-growing, nontuberculous mycobacterium associated with outbreaks in cardiac-surgery patients supported on heart-lung machines. We report a case of an elderly woman on chronic prednisone who presented with a six-month history of worsening chronic back pain, recurrent low-grade fevers, and weight loss. Imaging identifie...

Genetic transfer in Mycobacterium phlei.

Isolation from Mycobacterium Phlei

Mycobactin is the name suggested for a growth factor, present in acid-fast bacteria, which is essential for the growth of Mycobacterium johnei. A preliminary account ofthe work reported here has already been published (Francis, Madinaveitia, Macturk & Snow, 1949). Myco. johnei is an organism first observed by Johne & Frothingham (1895) in cases of chronic enteritis of cattle. It could not be cu...

Mycobacterium flavescens vertebral osteomyelitis in an immunocompetent host.

The aim of this paper is to describe a rare case of vertebral osteomyelitis caused by Mycobacterium flavescens in an immunocompetent patient. Mycobacterium flavescens is a rapidly growing, pigmented, non-tuberculous mycobacterium, usually described as non-pathogenic for humans but occasionally reported as the cause of serious infectious complications recognized in clinical practice. This study ...

Citrate formation in Mycobacterium phlei.

Although it is well known that citrate stimulates the growth of acid fast bacteria, the metabolic role of citrate is still obscure in this bacterial group. Washed suspensions of mycobacteria either fail to oxidize citrate or oxidize this substance slowly (Edson, 1951). On the other hand, clarified extracts of mycobacteria oxidize citrate to a-ketoglutarate (Geronimus, Gray, and Birkeland, 1949;...
