Resistance of Mycobacterium tuberculosis to the first line anti tubercular drugs--a twenty year review.

Tuberculosis and more so the multi drug resistant variety has been thrust into the forefront as a serious and life threatening illness in recent years. The advent of AIDS contributes to this substantially, especially in the developed world where it had become practically non- existent. We reviewed our data over the past 20 years with a view to determine when drug resistance began to manifest in the strains.

Mycobacterium fortuitum: an iatrogenic cause of soft tissue infection in surgery.

Background: Mycobacterium fortuitum is an uncommon cause of soft tissue infections. Treatment is often inadequate with persistence of infection unless the aetiological agent and its antibiotic sensitivity are accurately established.

Methods: Medical records of 23 patients with chronic soft tissue infection caused by M.

Detecting mycobacteraemia for diagnosing tuberculosis.

Background & Objectives: In human immunodeficiency virus (HIV) infected persons with pulmonary tuberculosis (TB), sputum may not always show acid fast bacilli (AFB). Moreover, in most cases of suspected extrapulmonary TB (irrespective of HIV status) mycobacteria-containing material is not readily available for investigation. This study evaluated whether blood culture for Mycobacterium tuberculosis bacteraemia (mycobacteraemia) help in diagnosing TB in such cases.

Drug resistant tuberculosis in diabetes mellitus: a retrospective study from south India.

This study was conducted in a tertiary care teaching hospital in south India to evaluate the association of drug resistant tuberculosis (TB) in diabetic subjects. There were: 361 subjects with positive mycobacterial culture and susceptibility tests results over a 3-year period; 267 (74%) acid-fast bacillus smear positive; and 94 (26%) smear negative cases. One hundred and seventy-seven (49%) had resistant isolates to any one first line antiTB drugs (resistant group) and 184 (51%) had isolates sensitive to all drugs (non-resistant group).

Perianal fistulae caused by Mycobacterium fortuitum.

Mycobacterium fortuitum is a rapidly growing Mycobacterium , which usually colonizes the soil, dust and water. It commonly causes skin and soft tissue infections especially in patients who have preceding trauma. We report a case of perianal fistulae caused by M.
