| [experimental findings after application of kveim antigen. ii. sensibilization of mice and guinea pigs by mycobacterium avium (serotype i) (author's transl)]. | mice and guinea pigs were sensibilisized by intraperitoneal injection of mycobacterium avium (serotype i). three and five weeks later (guinea pigs) and four weeks later (mice) the animals received kveim antigen into the footpads (guinea pigs) and into the perianal fat tissue (mice). three and five weeks later (guinea pigs) and four weeks later (mice) the exstirpated material was investigated by light microscopy and enzyme histochemistry. guinea pigs showed three and five weeks after injection of ... | 1979 | 494694 |
| enzyme-linked immunosorbent assay for detecting antibodies in swine infected with mycobacterium avium. | enzyme-linked immunosorbent assay (elisa) was used for detecting the antibodies in sera from swine experimentally infected with mycobacterium avium. positive elisa reactions were observed in the sera of each of six swine at postinoculation weeks 2, 4, 6, 8, and 10; no reaction was observed in noninoculated controls. the elisa reactions were observed in each of two swine at 4, 6, 8, 10 weeks following exposure to m avium-infected swine. mycobacterium avium-purified protein derivative and killed c ... | 1979 | 525914 |

| [experimental findings after application of kveim antigen. iii. sensitization of mice with living and killed strains of mycobacterium avium (author's transl)]. | mice were infected with mycobacterium avium (serotype i and serotype ii). the application of kveim antigen or two kinds of lipid fractions of mycobacterium avium (serotype i or ii) is followed in all cases by typical tissue reactions resembling positive kveim tests. control animals which only received kveim antigen or lipid fractions of mycobacterium i showed in all cases negative kveim reactions. sensibilization of mice with killed kinds of mycobacterium avium i or ii leads after application of ... | 1979 | 552201 |
| [antigenic and allergenic properties of various atypical mycobacteria and mycobacterium avium. i. immunoelectrophoretic analysis of antigens in water extracts]. | 4 strains of acid-resistant bacilli were examined: m. kansasi, scotochromogenic bacilli of nicolas strain, m. fortuitum and m. avium d4. water extracts prepared from these strains according to whiteside and baker method were used as antigens in the immunoelectrophoresis reaction and were also used to obtain specific serums on rabbits which were hyperimmunized according to tuboly's method. in the immunoelectrophoresis reaction water extracts were examined against nonsaturated serums, as well as c ... | 1979 | 554988 |
| the specificity and sensitivity of the fluorescent antibody test in cattle experimentally infected with mycobacterium avium and mycobacterium johnei. | in five calves experimentally infected with mycobacterium avium and in 10 with m johnei it was shown that the serological response by the fluorescent antibody (fa) test was specific. the serological response in the m avium infected calves was transitory and lasted up to five months. the first evidence of a serological response with the fa test in the m johnei dosed calves occurred at four months, and all calves had reacted by nine months after dosing. at the 23 tests carried out between four and ... | 1976 | 769123 |

| enhancement of humoral immune responses. i. potentiating influence of purified protein derivative on the invitro immune response of spleen cells sensitized to mycobacterium bovis and mycobacterium avium. | addition of purified protein derivate (ppd) to suspension cultures of spleen cells from swine sensitized to mycobacterium bovis and mycobacterium avium resulted in marked enhancement of antisheep erythrocyte plaque-forming cells after stimulation with sheep erythrocytes. the enhancing effect appeared early in the response and was specific for the sensitizing antigen. the enhancing effect was dependent upon the presence of both sheep erythrocytes and ppd in the culture system. ppd had no effect i ... | 1976 | 797671 |
| lesions and tuberculin sensitivity in calves inoculated with group iii mycobacterial isolates from swine, pen soil, and cattle feed. | fifteen calves, 7 to 11 months of age, were inoculated intradermally with group iii mycobacteria ---6 isolates from swine, 1 isolate from cattle feed, and 2 isolates from soil of swine farrowing pens. calves were tuberculin tested at 50 days and killed approximately 60 days after inoculation. only 1 of the cultures, that of porcine origin (93c-0), produced any lesions. there were a caseo-calcareous granuloma 3mm in diameter in the regional lymph node (left prescapular) and a granuloma at the ski ... | 1975 | 806238 |
| comparison of lymphocyte stimulation and tuberculin skin reactivity in mycobacterium bovis-infected macaca mulatta. | lymphocyte immunostimulation tests were conducted on mycobacterium bovis-infected and tuberculin-negative rhesus macaques (macaca mulatta), using purified protein derivative (ppd) tuberculins prepared from strains of mycobacterium tuberculosis and mycobacterium avium. the stimulation of lymphocytes with m tuberculosis ppd was significantly greater for the m bovis-infected macaques than for the noninfected controls (p smaller than 0.05). the response of lymphocytes from m bovis-infected macaques ... | 1975 | 806239 |
| 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 ... | 1979 | 572193 |
