[demonstration of brucella antigens in situ in mouse cells and spleen by electron microscopy].the immunoglobulins of rabbit anti-brucella immunsera were conjugated to horse radish peroxydase and used to revell the bacterial antigens during the experimental infection of mice with brucella suis. the technique seems to make possible the identification of bacteria that have undergone morphological modifications after phagocytosis.1975806390
brucella suis infection in pregnant cattle.six pregnant, bos taurus cows with stages of gestation ranging from 11 to 33 weeks were each inoculated into the right conjunctival sac with 0.2 ml of a smooth culture of brucella suis type i containing 27 x 10(6) viable organisms. the 6 cows produced 7 calves of which one single calf and one twin calf were stillborn, the cause of which was not determined. br. suis was not isolated from any of the cows or calves using either special media or guinea pig inoculation. no abnormality was found in an ...1979543824

[adherent cell and t lymphocyte cooperation for the "in vitro" production of brucella-induced interferon by murine spleen cells (author's transl)].although brucella is a good in vivo inducer of interferon, in vitro infection of murine spleen cells by brucella suis has not, to the present time, led to in vitro synthesis. in the present work we show that normal spleen cells can however synthetize interferon in vitro when cultured together with adherent cells obtained from the spleens of syngeneic mice 45 min after in vivo inoculation. induction and synthesis are thus shown to be distinct phenomena. moreover soluble factors are shown to be in ...1978310656

studies on brucella interferon: chromatographic behaviour and purification.interferon was induced by infecting mice with brucella suis. serum containing interferon activity was analyzed by chromatography on concanavalian a-sepharose and phenyl-sepharose cl-4b columns. antiviral activity was completely retained by the lectin column indicating that all the interferon molecules are glycosylated. the chromatographic behaviour of brucella interferon on phenyl-sepharose cl-4b shows that, like other interferons, brucella displays hydrophobic properties. however, the hydrophob ...19806154449
[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 ...19826812273
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 ...19836418758

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 ...19816784617
acute and chronic hepatic involvement of brucellosis.two patients with brucellosis are presented; one with acute hepatitis and the other with a chronic draining sinus at the right costal margin which originated from an abscess of the liver. brucella abortus infection may be manifest by nonspecific hepatic inflammation or, occasionally, by granulomatous hepatitis. rarely, cirrhosis may result if untreated. chronic hepatic and splenic involvement, which is characterized by tissue calcification, can be seen in brucella suis infection. suppurative com ...19827084621
[enteral yersiniosis--a serious disease? current knowledge of clinical aspects, diagnosis and therapy].enteral yersiniosis is caused either by y. enterocolitica 0-group i (syn. serotype 0:3) and 0-group v (syn. serotype 0:9) or y. pseudotuberculosis type i-vi. the clinical symptoms are mostly like enteritis, enterocolitis, acute abdomen, mesenteric lymphadenitis, or ileitis terminalis. post-infection reactions are possible like septicemia, arthritis and erythema nodosum. only cultural and serological examinations confirm the diagnosis of enteral yersiniosis. in the judgement of serological result ...19827095694

brucellosis in wild swine: a serologic and bacteriologic survey in the southeastern united states and hawaii.sera from wild swine from 20 populations in 11 southeastern states and hawaii were tested for brucellosis by the card, tube, plate, buffered plate antigen, complement-fixation, and rivanol tests. twenty-one of 352 (6.0%) swine were considered seropositive, and these animals originated from 7 populations in 5 states: arkansas, florida, georgia, louisiana, and south carolina. cultural examinations for brucella suis also were made from subsamples of the swine tested serologically. brucella suis bio ...19827174444
genetic factors involved in murine susceptibility to experimental brucellosis.c57bl/6 are more resistant than dba2 mice to brucella suis 1330. this difference does not concern the blood clearance of the i.v. inoculated bacteria or the number of infective colonies in the spleen at very early stages but the splenic infection at later stages with maximal differences on day +7. the "resistance" character is inherited by f1 and back-crosses as a partially dominant character with polygenic control and a better expression of resistant factor(s) in females. this phenomenon of sex ...19816957160
[attempts of ultrastructural and biochemical characterisation of cell wall deficient "brucella" (l forms) (author's transl)].in previous studies the in vivo conversion of brucella suis to l-form state was put in evidence. the l forms isolated from mouse spleen had original structural aspects in common: the absence of the cell wall layer and the extracellular multilayer "membranous" structures. the biological characterization of these l forms and the preliminary identification of specific chemical markers of the bacterial envelope is reported in the present study, performed with the stable l forms well-growing in the l ...19827103308
