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
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
an estimated prevalence of johne's disease in a subpopulation of alabama beef cattle.the objective of this study was to estimate the overall prevalence of animals that were infected with mycobacterium avium ssp. paratuberculosis in a subpopulation of alabama beef cattle. this was determined using a commercial enzyme-linked immunosorbent assay (elisa) for the detection of m. avium ssp. paratuberculosis-specific antibodies in serum. serum was collected from 79 herds that were participating in the alabama brucellosis certification program. a total of 2,073 beef cattle were randomly ...200312580290
epidemiology of infection by nontuberculous mycobacteria. v. numbers in eastern united states soils and correlation with soil characteristics.organisms of the mycobacterium avium, m. intracellulare, and m. scrofulaceum (mais) group were recovered in significant numbers from 63 soil samples collected from the floodplains of 4 major rivers in the eastern united states: hudson (ny), james (va), savannah (ga, sc), and tombigbee (al, ms). the mean numbers of m. avium-intracellulare, m. scrofulaceum, and mais-intermediate biovars recovered increased significantly from the hudson to the james to the tombigbee and savannah soil samples, agree ...19846486562
mycobacterium avium-intracellulare from a vietnamese refugee.mycobacterium avium-intracellulare grew from the sputum of a vietnamese woman, a recent immigrant, seen at a tuberculosis clinic in birmingham, alabama. the possibility that she had acquired this mycobacterium in her native vietname was considered, since current literature, indicates these agents have no predictable geographic patterns of distribution. data indicate that outside the united states group iii mycobacterial isolates are most common in japan, western australia, and parts of canada. ...1978663707
