[Drug-resistant Mycobacterium tuberculosis in children under 15 years].

Introduction: Tuberculosis is a widespread and increasingly important infectious disease. A third of the world-wide population is infected. Every year nine million cases occur in the world, one million of them appearing in children under 15 years old.

Disseminated mycobacteriosis affecting a prosthetic aortic valve: first case of Mycobacterium peregrinum type III reported in Colombia.

Rapidly growing mycobacteria are non-tuberculous mycobacteria amply present in the environment. Although they are not usually pathogenic for humans, they are opportunistic in that they can cause disease in people with disadvantageous conditions or who are immunocompromised. Mycobacterium peregrinum, an opportunistic, rapidly growing mycobacteria, belongs to the M.

Cutaneous tuberculosis after mesotherapy: report of six cases.

Introduction: Cutaneous tuberculosis as a result of a needle injection is a rare event; it generally occurs among medical and laboratory personnel and among patients receiving percutaneous treatment.

Objective: Six patients are presented who developed cutaneous tuberculosis after mesotherapy cosmetic treatment.

Material And Methods: One to four months after injection of an unknown product as treatment for obesity and cellulites, five women and a man developed papules, nodules and drainage of wax like material at the inoculated sites; this was interpreted clinically as a non tuberculous mycobacterium infection.

[Molecular identification of non-tuberculous mycobacteria].

Introduction: Nontuberculous mycobacteria can be saprophytic, pathogenic or opportunistic. The most common diseases produced by these microorganisms are the post-surgical infections due to anesthetic procedures, infections associated with catheters, disseminated cutaneous diseases and pulmonary and central nervous system diseases that especially affect HIV patients. Identification of the nontuberculous mycobacteria can take several weeks and even then, differentiation of complex members is not possible.
