| comparison of the effects of acid and base hydrolyses on hydroxy and cyclopropane fatty acids in bacteria. | the cellular fatty acid compositions of legionella oakridgensis, brucella suis, pseudomonas aeruginosa, and francisella tularensis were compared after base hydrolysis (saponification), acid hydrolysis, and acid methanolysis procedures were used to release the fatty acids. the branched-chain, unsaturated, saturated, and ester-linked hydroxy acids were released as effectively with saponification at 100 degrees c for 30 min as with acid hydrolysis or acid methanolysis at 85 degrees c for 16 h. alth ... | 1983 | 6418758 |
| [brucellosis in rabbits induced by an experimental infection with brucella suis germs]. | hares were experimentally infected with brucella suis germs, biotype 2, to study the development of morphological changes in the organs. it was demonstrated that conjunctival and intranasal infection caused morphological brucellosis changes in liver. after conjunctival infection affections were observed in 16 days, and in 27 days after intranasal infection. the morphology of changes did not differ from those occurring in spontaneous brucellosis. the results of morphological examination correspon ... | 1984 | 6426134 |
| [morphological changes in brucellosis in guinea pigs due to experimental infection with brucella suis]. | sixty-four guinea-pigs were infected with the germs of brucella suis. biotype 2 via the vaginal, peroral, intranasal, conjunctival and subcutaneous routes. in the subcutaneous infection the length of the trial was 151 days and in the other methods of infection 56 days. as found, guinea-pigs are highly sensitive and brucellosis lesions were detected in all cases. brucellosis was chronical and spread locally in the guinea-pigs. in the haematogenic spreading of the disease, lesions were constantly ... | 1984 | 6433534 |

| genetic factors involved in murine resistance to experimental brucellosis. | c57 b1/6 are more resistant than dba2 mice to iv inoculation of brucella suis 1330. this difference does not concern the blood clearance of the injected bacteria or the number of infective colonies in the spleen at very early (less than 24 h) or at late (greater than 2 months) stages but the splenic infection at intermediate stages with maximal differences between days 7 and 14. the "resistance" character is inherited by f1 and backcrosses as a partially dominant character with polygenic control ... | 1984 | 6593265 |
| induction of autoantibodies and circulating immune complexes in mice after injection of brucella fraction "pi" or inoculation with live brucella suis. | "pi", a vaccinating fraction with b mitogenic and polyclonal activator (pca) activity extracted from brucella melitensis, was i. p. injected into b6 and db mice. in b6 mice, this led to an important but transient increase in the level of anti-ssdna antibodies, the induction of rheumatoid factor (rf) and the appearance of circulating immune complexes (cic). in db mice, on the other hand, the only significant effect consisted of a slight and ephemeral peak of cic in sera from day 7. similarly, whi ... | 1983 | 6602586 |
| binding of bacteria from the genus brucella to human b lymphocytes. | in previous studies, we have shown that various lymphocyte subpopulations bind different strains of bacteria of different genera and species. among these bacteria was a strain of brucella melitensis which bound to all human b lymphocytes. to determine whether the binding of b. melitensis to human b lymphocytes was strain, species, or genus characteristic, we tested the binding of b. melitensis, brucella abortus, brucella ovis, brucella suis, brucella canis and brucella neotomae to human normal a ... | 1981 | 6783546 |
| effects of killed brucella abortus strain 45/20 vaccine on reindeer later challenge exposed with brucella suis type 4. | six seronegative pregnant reindeer (rangifer tarandus l) were vaccinated with killed brucella abortus strain 45/20 with added adjuvant. these were challenge exposed with b suis type 4 after 90 days; at the same time, 4 seronegative, nonvaccinated, pregnant reindeer (controls) were given the challenge inoculum. humoral antibodies were detected in the vaccinated reindeer by postvaccination day 14. a marked increase in antibody levels also occurred after they were challenge exposed, but did not rea ... | 1981 | 6784617 |
| [pathomorphological changes in brucellosis in hares]. | the morphology of 645 cases of brucellosis in hares evoked by the germs of brucella suis, biotype 2, is described. brucellosis had the character of chronic granulomatous process with prevailing changes in liver, spleen and in sex organs of hares of both sexes. in the sex organs of sexually immature hares the changes were detected in 2.26% of animals. the granuloma macroscopy was typical and was most discernible in liver. in the organs there prevailed solitary granulomas of the pea size. in teste ... | 1982 | 6812273 |

| development of an enzyme-linked immunosorbent assay for detecting antibodies in sera of brucella suis-infected swine. | an enzyme-linked immunosorbent assay was developed using a heat-killed brucella suis antigen for detecting antibodies in the sera of swine from which b. suis was isolated. optimal enzyme-linked immunosorbent assay reactions were obtained using heat-killed b. suis antigen at a concentration comparable to mcfarland standard no. 1. statistically significant differences were observed in the enzyme-linked immunosorbent assay results of 40 animals from which b. suis was isolated and the results for 48 ... | 1980 | 7000319 |
