| prevalence of mycobacterium avium complex in respiratory specimens from aids and non-aids patients in a san francisco hospital. | over the past several years there has been a large increase in the recovery of mycobacterium avium complex (mac) isolates from respiratory specimens submitted to the clinical laboratory at san francisco general hospital (sfgh). this increase in mac recovery correlates with an increase in the number of cases of acquired immunodeficiency syndrome (aids) in the community. although it is well known that mac is often isolated from patients with aids, the isolation of mac from respiratory specimens is ... | 1991 | 1986686 |
| mycobacterium avium complex in water, food, and soil samples collected from the environment of hiv-infected individuals. | as part of an epidemiologic study of mycobacterium avium complex (mac) infection in san francisco, water, food and soil samples were collected from the home environment of 290 persons with human immunodeficiency virus (hiv) infection and cultured for mycobacteria. isolates recovered from the environment were compared with isolates cultured from study patients. although mycobacteria were recovered from numerous environmental samples, isolates reactive with mac-specific dna probes were recovered f ... | 1995 | 7749796 |
| missed tb in aids unit leads to tighter isolation. | the san francisco general hospital recently tightened its tuberculosis (tb) policies for isolating hiv-positive patients after learning that active tb patients had been admitted without respiratory protection. the new policy resulted from what was initially believed to be a tb outbreak on the aids unit. however, an investigation concluded that the patients were infected outside the hospital. the hospital now automatically screens patients for tb when they are admitted to the aids ward. hiv-posit ... | 1996 | 11363656 |
| cmv. | cytomegalovirus (cmv) occurs 25 percent less often than it did before the advent of highly active antiretroviral therapy (haart), according to a recent study by the university of california at san francisco. cmv is the most common infection in hiv-positive persons with t-cell counts below 50, and it can cause blindness. researchers have also found that macrolide antibiotic treatment for mycobacterium avium complex (mac) may lead to resistance in people with aids who have been treated for mac in ... | 2000 | 11366342 |
| mycobacterium avium subspecies paratuberculosis and mycobacterium avium subsp. avium infections in a tule elk (cervus elaphus nannodes) herd. | between 2 august and 22 september 2000, 37 hunter-killed tule elk (cervus elaphus nannodes) were evaluated at the grizzly island wildlife area, california, usa, for evidence of paratuberculosis. elk were examined post-mortem, and tissue and fecal samples were submitted for radiometric mycobacterial culture. acid-fast isolates were identified by a multiplex polymerase chain reaction (pcr) that discriminates among members of the mycobacterium avium complex (mac). histopathologic evaluations were c ... | 2006 | 17255437 |
| amplified fragment length polymorphism analysis of mycobacterium avium complex isolates recovered from southern california. | fine-scale genotyping methods are necessary in order to identify possible sources of human exposure to opportunistic pathogens belonging to the mycobacterium avium complex (mac). in this study, amplified fragment length polymorphism (aflp) analysis was evaluated for fingerprinting 159 patient and environmental mac isolates from southern california. aflp analysis accurately identified strains belonging to m. avium and mycobacterium intracellulare and differentiated between strains within each spe ... | 2007 | 17761476 |
