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
opportunistic disorders of the gastrointestinal tract in the age of highly active antiretroviral therapy.since the 1996 advent of highly active antiretroviral therapy (haart) for the treatment of hiv/aids, the incidence of most opportunistic disorders in the developed world has dramatically declined but definitely has not disappeared. the number of new yearly hiv infections (about 55,000) and the total number of us infections (more than 1.1 million) remain very significant. post-haart gastrointestinal (gi) symptoms and biopsy results are still common, especially in large inner-city hospitals. the s ...201021078437
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
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. 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
