the extent and importance of sensitization by opportunist mycobacteria in lagos, nigeria.3505 school children aged 6 to 15 years were tested with ppds and at the same time one of the following tuberculins, namely, ppdg, ppdpl, ppda, ppdf and ppdy. the tuberculins were prepared from human tubercle bacillus, the gause organism, m. marinum, m. avium, m. fortuitum and m. kansasii respectively. ppdy, ppda and ppdg gave more reactions of greater than 2 mm induration than did ppds. furthermore, tests with ppdy, ppda, ppdg and ppdpl showed a significant proportion of children with reactions ...1977414397
culture and serologic survey for mycobacterium avium subsp. paratuberculosis infection among southeastern white-tailed deer (odocoileus virginianus).from july 1998 through october 2002, radiometric culture (ileocecal lymph node, mesenteric lymph node, and feces) and serologic testing by enzyme-linked immunosorbent assay (elisa) were used to survey white-tailed deer (odocoilens virgianus) from the soutlheastern united states for infection by mycobacterium avium subsp. paratuberculosis (mptb), the causative agent of paratuberculosis (johne's disease). mycobacterium avium subsp. paratuberculosis was isolated from the ileocecal lymph node of one ...200415362831
epidemiology of infection by nontuberculous mycobacteria. vi. identification and use of epidemiologic markers for studies of mycobacterium avium, m. intracellulare, and m. scrofulaceum.a comparison of clinical and environmental (e.g., soil, dust, water, and aerosol) isolates of the mycobacterium avium-intracellulare and m. scrofulaceum (mais) group has been made. the frequency of m. avium-intracellulare clinical isolates able to grow without oadc enrichment, able to grow at 43 degrees c, or express resistance to streptomycin or cadmium was significantly higher than those among environmental isolates. only the frequency of clinical m. scrofulaceum isolates able to grow at 43 de ...19863729160
epidemiology of infection by nontuberculous mycobacteria. mycobacterium avium, mycobacterium intracellulare, and mycobacterium scrofulaceum in acid, brown-water swamps of the southeastern united states and their association with environmental variables.mycobacterium avium, mycobacterium intracellulare, and mycobacterium scrofulaceum (mais) organisms were isolated and identified from waters, soils, aerosols, and droplets ejected from water collected from four geographically separate aquatic environments (okefenokee swamp, ga; dismal swamp, va; claytor lake, va; and cranberry glades, wv) during several seasons. recovery of mais was significantly higher from waters, soils, and aerosols collected from the two acid, brown-water swamps located in th ...19921736730
disseminated mycobacterium avium complex infection: clinical identification and epidemiologic evaluate the incidence of disseminated mycobacterium avium complex infection (dmac) and to define the association between signs and symptoms and development of dmac in patients with human immunodeficiency virus (hiv) infection, all cases of dmac at grady memorial hospital infectious disease clinic (atlanta) between 1985 and 1990 were reviewed, and a prospective study of the association of symptoms with dmac was done. between 1985 and 1990, dmac occurred in 16% of patients with aids. incidence ...19921347060
the seroprevalence of johne's disease in georgia beef and dairy cull cattle.beef and dairy cattle serum samples, collected during 2000 at sale barns throughout georgia, were obtained from the georgia state brucellosis laboratory and were used to conduct a retrospective epidemiological study. statistical samplings of 5,307 sera, from over 200,000 sera, were tested for antibodies to mycobacterium avium ssp. paratuberculosis, (johne's disease) using a commercial enzyme-linked immunosorbent assay test kit. an overall period seroprevalence in all classes of cattle tested was ...200314535551
epidemiology of infection by nontuberculous mycobacteria. vii. absence of mycobacteria in southeastern groundwaters.using the fluorochrome auramine-o, direct microscopic counts of log phase cells of mycobacterium avium, m. intracellulare, and m. scrofulaceum (mais) group showed excellent correlations with viable spread-plate counts. accordingly, an enumeration of total acid-fast and mais cells by stain and culture (respectively) in groundwaters from three united states regions that differ in their incidence of human infection by mais was undertaken. of 30 state-monitored, undisinfected wells, 11 were in georg ...19872441632
sensitivity to avian purified protein derivative in cattle from farms having a high prevalence of swine mycobacteriosis.on two farms in north georgia a large percentage of the swine was infected with organisms of the mycobacterium avium-intracellulare-scrofulaceum complex. the hypothesis that the cattle on these farms, which are maintained separately from the swine, would not be sensitive to avian purified protein derivative was rejected. it was concluded that the source of the m. avium-intracellulare-scrofulaceum complex of each animal population is environmental.19817235698
distribution of serotypes of the mycobacterium avium-intracellulare-scrofulaceum complex in georgia.cultures of the mycobacterium avium-intracellulare-scrofulaceum (mais) complex, isolated from patients who lived throughout the state of georgia, were studied using the serotyping scheme of schaefer. one hundred four (77 per cent) of the 135 isolates tested could be classified into 16 serotypes. the rest were not typable. fifty-eight per cent of all the typable strains were serotypes 1, 14, 16, and 42. results of the serotyping were recorded, mapped, and analyzed by county of residence. most fre ...1979572193
hospital water as a source of mycobacterium avium complex isolates in respiratory specimens.the clinical significance of recovery of mycobacterium avium complex (mac) organisms from respiratory specimens is poorly understood. one hundred sixty-one respiratory mac isolates from 131 patients at grady memorial hospital (atlanta) and 13 mac isolates from the hospital's hot water system were examined. of the 131 patients, 35 (27%) had mac disease, and 96 (73%) did not; 94 (72%) were human immunodeficiency virus infected. ten different clusters were identified by pulsed-field gel electrophor ...200414702159
recent experience in the epidemiology of disease caused by atypical obtain information on the epidemiology of mycobacteriosis, water and air samples collected along the east coast of the united states were examined for mycobacteria. mycobacterium avium-intracellulare-scrofulaceum (mais) were isolated from 25% of the water, samples, mostly those from south carolina, georgia, and the gulf states. mycobacterium kansasii and mycobacterium marinum were not found, probably because of the detrimental effects of the naoh used to decontaminate the samples. mais strain ...19817339831
