gross and microscopic lesions of naturally occurring tuberculosis in a captive herd of wapiti (cervus elaphus nelsoni) in colorado.a mycobacterium bovis-infected herd of captive wapiti (cervus elaphus nelsoni) in colorado was depopulated after lesions of bovine tuberculosis were confirmed in 8 of 10 tuberculin skin test reactors. of the 43 animals > 1 year of age, 26 had gross lesions suggestive of tuberculosis, 24 had microscopic lesions of tuberculosis, and 23 had acid-fast bacilli associated with the lesions. lungs and retropharyngeal lymph nodes were the most frequently affected sites. most lesions grossly and microscop ...19921457546
serum antigen 85 levels in adjunct testing for active mycobacterial infections in orangutans.diagnosis of active mycobacterial disease in orangutans (pongo pygmaeus) has been impeded by high levels of non-specific intradermal skin test reactivity to mycobacterial antigens. this may be due in part to cross reactivity between antigens, tuberculin concentrations used or other species-specific factors. antigen 85 (ag85) complex proteins are major secretory products of actively growing mycobacteria, and measurement of serum ag85 could provide a method for determining active mycobacterial inf ...200111272506
