Mycobacterium haemophilumin Immunocompromised Patients

Mycobacterium haemophilum in immunocompromised patients.

Mycobacterium haemophilum, a recently described pathogen, can cause an array of symptoms in immunocompromised patients. To date, 90 patients with this infection have been described worldwide. We report our institution's experience with 23 patients who were treated from 1990 through 2000. Fourteen patients had undergone bone marrow transplantation, 5 were infected with human immunodeficiency vir...

Niacin-positive Mycobacterium kansasii isolated from immunocompromised patients.

Niacin-positive Mycobacterium kansasii was isolated from three patients, two with respiratory infections and one with a perirectal abscess. The isolates were phenotypically similar to other strains of M. kansasii, differing only in their ability to produce niacin. This phenotype has been reported only twice in the literature, during the 1960s.

Etiologic Agents of Candidemia in Pediatric Immunocompromised Patients

Abstract Background: Candidemia is the main cause of fungal nosocomial bloodstream infections and is related to meaningful mortality specially, in pediatrics. Mortality rate range from 5% to 71%, and it can reach as high as 81%. Delays in beginning of treatment have also been linked to intensified mortality. The epidemiology of Candida infection is changing from region to region. Regiona...
