| osmotically sensitive brucella in infected normal and immune macrophages. | when brucella suis is grown in tissue cultures of normal guinea pig macrophages, the brucella multiplies significantly without the induction of osmotically sensitive forms. in immune macrophages in the presence of normal guinea pig serum, there is a reduction in the number of intracellular brucella and no multiplication is seen over a 72-hr period. after 6 hr of exposure to immune macrophages, however, approximately 50% of the surviving intracellular brucella are osmotically sensitive, i.e., the ... | 1970 | 16557705 |
| separation of soluble brucella antigens by gel-filtration chromatography. | soluble precipitating antigens of brucella suis have been, in various degrees, purified by filtration on sephadex gels. the most useful gels employed were sephadex g-150, sephadex g-200, and sepharose 4b. although not all fractions proved to be immunologically pure, some crude molecular-size estimates of most of the 13 soluble antigens of the brucella cell could be given. in addition, monospecific antisera to three purified brucella antigens have been prepared. by using purified preparations, ph ... | 1970 | 16557798 |
| fractionation of phenol extracts from brucella suis: separation of multiple biologically active components. | brucella suis endotoxin prepared by a modification of westphal's method was purified further by gel filtration and ion-exchange chromatography. the latter proved to be the most effective means of separating antigenic components associated with this fraction. all of the toxic activity was located in a single peak from carboxymethyl-sephadex. subsequent separation of this material on diethylaminoethyl (deae)-sephadex indicated the presence of two or more toxic components in phenol extracts of b. s ... | 1970 | 16557826 |

| brucella suis infection in philadelphia. a survey of hog fever and asymptomatic brucellosis. | examination of hospital and public health records revealed 19 cases of brucellosis diagnosed in philadelphia between 1968 and 1972. a serologic survey at philadelphia's largest hog-processing plant, however, indicated infection in 39% of workers. if extrapolated industry-wide, the total would be several hundred in philadelphia. the infection is usually unrecognized or asymptomatic, since men were active in physically demanding jobs with agglutinin titers in excess of 1:5000. overt illness, usual ... | 1976 | 1247015 |
| [brucellic mammitis in sows]. | in a herd of pigs, 31% presented serological reactions positive or doubtful to brucellic infection; in 15% of the sows the mammary glands were swollen and purulent; the retromammary ganglions were enlarged and hemorrhagic. bacteriological examination of the pus of mammary lesions showed the presence of brucella suis, which confirmed the diagnosis of brucellic mammitis in the sows. the purulent discharge of the mammary lesions, diluted with physiological serum, agglutinated with the antibrucellic ... | 1976 | 1261741 |
| evolution and taxonomy in the genus brucella: concepts on the origins of the contemporary species. | the flow of thought on evolution of the organisms in the genus brucella was traced through the literature. the finding of brucella suis type 2 in hares provided impetus for much speculation on the changeability of species characteristics. recent reports, largely by soviet investigators, focus on the subjects of the sweep of evolution in this genus through eons of the geologic time scale and also on the possible parentages of the recently discovered species. these papers were translated and perti ... | 1976 | 816230 |
| evolution and taxonomy in the genus brucella: steroid hormone induction of filterable forms with altered characteristics after reversion. | several strains of brucella abortus, brucella suis, and brucella melitensis were exposed to physiologic concentrations of testosterone, progesterone, and diethylstilbestrol by incorporating them into the growth medium. the hormones induced brucella to form cell wall-defective organisms, including filterable forms. the filterable forms from 1 strain of b melitensis had altered characteristics when it reverted to growth as an intact cell. this is the 1st reported instance of induction of filterabl ... | 1976 | 816232 |

| brucellosis in feral swine. | some 255 feral hogs were serologically tested for brucella titers at a location in the lower coastal plain of south carolina. eighteen percent were reactors. the organism was cultured from lymph node tissues in one 3+ years old boar and identified as brucella suis biotype 1. prevalence of sero-positive animals increased with age. there were no important differences between sexes. | 1976 | 16502703 |
| [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 ... | 1978 | 310656 |
| comparative studies on the ultrastructure of l forms obtained from s and r variants of brucella suis 1330. | electron-microscopic studies were carried out on s and r variants of brucella suis 1330 and the production of l forms induced with the use of penicillin. no variations were established in the ultrastructure of the initial forms. however, essential differences were observed in the ultrastructure between the latter and the l-transformed brucellae as well as changes that differentiated the ultrastructure of l forms obtained from s variants from that of l forms obtained from r variants. in both case ... | 1978 | 636707 |
| brucellosis in reindeer, rangifer tarandus l., inoculated experimentally with brucella suis, type 4. | an investigation of brucellosis caused by brucella suis, type 4, in reindeer, rangifer tarandus l., and other ungulates inoculated experimentally with virulent isolates was undertaken to observe the course of infection, follow titres of serum agglutins, and determine the extent to which intraspecific and interspecific transmission might occur among confined animals. titres rose to maximum levels within 1 to 2 months following inoculation, decreased during the next 4 months, and persisted at low ... | 1978 | 647470 |

| immunologic properties of soluble materials from brucella species. | the purpose in this study was to examine the immunogenic properties of various preparations of aqueous ether extracts of brucella suis and brucella canis. the b suis strain 3b and b canis strain rm-6-66 were grown on tryptose agar, and aqueous ether extracts were prepared from the cells. the ether was removed, and the extracts were clarified by centrifugation for 10 hours at 144,000 x g and fractionated by gel chromatography. the b suis endotoxin-containing precipitate, obtained from aqueous eth ... | 1979 | 464362 |
| 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 ... | 1979 | 543824 |
| 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 ... | 1980 | 6154449 |
| 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 |
| experimental infections by brucella suis type 4 in alaskan rodents. | the susceptibility of nine species of rodents and one species of lagomorph to brucella suis type 4 was studied experimentally. the rodent species included: guinea pig (cavia porcellus), scandinavian lemming (lemmus lemmus), brown lemming (l. sibiricus), northern red-backed vole (clethrionomys rutilis), varying lemmings (dicrostonyx stevensoni and d. rubricatus), yellow-cheeked vole (microtus xanthognathus), flying squirrel (glaucomys sabrinus) and ground squirrel (citellus parryii). the lagomorp ... | 1980 | 7463596 |
| effect of rifampicin and tetracycline alone and in combination against brucella suis. | in vivo and in vitro efficacy of rifampicin and tetracycline hydrochloride, used alone and in combination, was tested against one strain of brucella suis. the minimal inhibitory concentrations of rifampicin and tetracycline hydrochloride against this strain were 2 and 0.2 microgram/ml, respectively. in vitro efficacy was evaluated by inhibition of bacterial growth in liquid medium. rifampicin killed 99.9% of the brucella after 18 h of incubation of concentrations of 2 and 4 microgram/ml. tetracy ... | 1980 | 7469256 |
| dissociation of delayed-type hypersensitivity from acquired murine resistance to brucella suis. | mouse pretreatment with cyclophosphamide or acetoacetylation of the vaccinating fraction "pi" lead to a dissociation between enhanced anti-pi dth responses and normal or depressed acquired resistance to an infective challenge with brucella suis. | 1980 | 7469385 |
| experimental brucella suis type 4 infections in domestic and wild alaskan carnivores. | beagle dogs were readily infected by 1.3 x 10(8) colony forming units (cfu) of brucella suis type 4 administered either on canned dog food, or intraperitoneally. such infections were afebrile and otherwise asymptomatic and without any obvious gross lesions. inoculation of 10(8) cfu b. suis type 4 intraperitoneally into two gravid wolves (canis lupus) resulted in infections in both animals. about 24 days later they gave birth, apparently at full-term, to two (both alive) and six (two alive and fo ... | 1981 | 7241703 |
| cellular fatty acids of brucella canis and brucella suis. | the cellular fatty acid composition of brucella canis and brucella suis was determined by gas-liquid chromatography. the presence of relatively large amounts of a 19-carbon cyclopropane fatty acid in b. suis was a major distinguishing feature between these organisms. the gas-liquid chromatography test for cellular fatty acids provides an additional criterion for the distinction of antigenically rough strains of b. suis which cannot be differentiated from b. canis by conventional procedures. | 1981 | 7263850 |
| isolation of l-forms from the spleens of brucella suis-infected, penicillin-treated mice. | previous attempts to obtain in vitro wall-deficient stable l-forms of various strains of brucella have failed because the obtained spheroplasts revert quickly to bacterial form. here, we report the isolation of l-forms from mice infected with a b. suis strain type 1 and treated with penicillin. in defined experimental conditions, l-type microcolonies associated with tissue debris were observed in primary spleen cultures, even on antibiotic free media. after several transfers on penicillin-contai ... | 1981 | 7294609 |

| 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 ... | 1981 | 6957160 |
| 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 |
