Studies on atypical acid-fast mycobacteria isolated from patients

A study on characteristics of atypical mycobacteria isolated from sputum specimens in Korea.

Is serious pulmonary disease caused by nonphotochromogenic ("atypical'') acid-fast Mycobacteria communicable?

Multidrug-resistant nontuberculous mycobacteria isolated from cystic fibrosis patients.

Worldwide, nontuberculous mycobacteria (NTM) have become emergent pathogens of pulmonary infections in cystic fibrosis (CF) patients, with an estimated prevalence ranging from 5 to 20%. This work investigated the presence of NTM in sputum samples of 129 CF patients (2 to 18 years old) submitted to longitudinal clinical supervision at a regional reference center in Rio de Janeiro, Brazil. From J...

Spheroplastic phase of mycobacteria isolated from patients with Crohn's disease.

Two strains of an unclassified Mycobacterium species were isolated after 18 and 30 months of incubation of media inoculated with resected intestinal tissues from patients with Crohn's disease. These strains represented the third and fourth isolates of this organism from Crohn's disease patients. Ultrastructural examination of this strain and two previously isolated strains revealed the presence...

Atypical acid-alcohol-fast bacilli cultured from human urines.

During the past seven years at this hospital the urines of all patients with skeletal tuberculosis have been examined at regular intervals with a view to detecting early renal infection. Our practice is to collect the first specimens passed on three successive mornings in sterile jars. These specimens are centrifuged in sterile tubes and samples of the deposits examined for pus and red cells an...
