Histologic Parameters Predictive of Mycobacterial Infection

Mycobacterial infection.

Tuberculosis and leprosy are two well known mankind diseases that are caused by members of the genus Mycobacterium. When originally named in 1896, this genus contained the leprosy bacillus (Mycobacterium leprae) observed by Armour Hansen in 1874 and the tubercle bacillus (Mycobacterium tuberculosis) observed and cultured by Robert Koch in 1882. As time went by, other bacilli similar to those of...

Clinical Analysis of Osteoarticular Nontuberculous Mycobacterial Infection.

OBJECTIVE The incidence rate of nontuberculous mycobacterial (NTM) infection has been increasing globally in recent years. However, reports of osteoarticular NTM infection are relatively rare. We report the characteristic clinical features of patients with osteoarticular NTM infection. PATIENTS AND METHODS We examined 14 patients with osteoarticular NTM infection (mean age, 68 years) were tre...

Mycobacterial infection of a congenital bronchogenic cyst.

Bronchogenic cysts result from an abnormal budding or branching of the tracheobronchial tree. Approximately 30% of the cysts are located in the mediastinum and the remaining 70% in the lung. The cyst may be joined to the tracheobronchial tree by a fistula or by a fibrous band. Pulmonary bronchogenic cysts occur most frequently in the lower lobes, primarily on the right side. They are thin-walle...

A Clear View of Mycobacterial Infection

Chemical reactions lie at the heart of many biological processes, from photosynthesis and respiration to cell signaling and drug metabolism. Thanks to an atmosphere rich in oxygen, many organisms use oxygen to carry out these life processes. But oxygen metabolism produces highly toxic by-products called reactive oxygen species. When oxidation outpaces detoxifying reactions, oxidative stress occ...
