| [a rare cause of infection in chronic dialysis patients: malta fever (febris undulans melitensis)]. | a 45-years-old greek patient developed septicaemia in his 10th year of hemodialysis treatment. clinical investigation was directed first on bacterial infection of the arteriovenous shunt, on urosepsis or bronchopulmonary infection. then, serologically (widal's reaction and elisa-test) and in different blood-cultures brucella melitensis was detected as causative agent for malta fever (febris undulans). the focus of infection is suspected in unpasteurized sheep-milk cheese of mediterranean origine ... | 1988 | 3172682 |
| enzyme-linked immunosorbent assay for brucella melitensis-associated antigens. | an elisa assay was performed to detect antigens of brucella melitensis directly in the blood of patients affected by brucellosis. disposable polystyrene microtiter plates were coated with rabbit immunoglobulins anti-brucella melitensis antigens and then incubated with sera of brucellosis patients and sera of not infected normal subjects as a control, to standardize the conditions of the different steps of the assay. the level of the blood-containing brucella antigen bound to the plate was measur ... | 1988 | 3173124 |
| anti-chlamydial immunity in ewes conferred by vaccination with a combination of three live chlamydia, brucella and salmonella vaccines. | live attenuated vaccines against chlamydia psittaci var ovis, brucella melitensis and salmonella abortus ovis have previously been shown to be compatible in mice by subcutaneous administration. immunity against challenge with virulent chlamydia was, however, slightly decreased in associations including the b melitensis rev 1 vaccine. the chlamydia strain 1b vaccine was administered to four- to five-month-old female lambs, either alone or in combination with the b melitensis rev1 and the s abortu ... | 1988 | 3176252 |
| the isolation and serology of the "fsa" brucella melitensis rev. 1 mutant in a flock of sheep. | a flock of sheep, known to be infected with the "fsa" mutant of brucella melitensis rev. 1, was examined serologically and bacteriologically to determine whether any relationship existed which would help in the control of this infection in the field. an attempt was also made to determine whether vertical transmission occurred. twenty-one out of 62 sheep were bacteriologically positive. the best organs for isolation were the udder, supramammary lymphnodes and uterus. no significant relationship c ... | 1988 | 3194120 |
| brucellar sternoclavicular arthritis, the forgotten complication. | of 511 cases of brucellosis studied between december 1983 and february 1986, four (0.8%) had sternoclavicular (stcl) arthritis. two were male and two female, and only one was younger than 50 years old. all four cases had significantly high specific igg antibody titres (1 of 1280), measured by the indirect immunofluorescent (iif) test, and two had brucella melitensis isolated from their blood. in two cases, stcl arthritis was the presenting problem, and it was associated in one with ankle arthrit ... | 1988 | 3250341 |
| acute hepatitis and brucella melitensis infection: clinicopathological findings. | the clinical and pathological findings in a patient who had acute hepatitis caused by brucella melitensis are described. antibiotic therapy induced a good clinical and biochemical response, although a relapse occurred. brucellosis must be considered in the differential diagnosis of pyrexia of unknown origin, particularly if associated hepatic involvement is present. a careful occupational and travel history is essential. | 1988 | 3259669 |
| polyclonal igg synthesis of mononuclear cells induced by the homopolymer of 4,6-dideoxy-4-formamido-alpha-d-mannopyranosyl units isolated from brucella melitensis. | brucella melitensis attaches selectively to b lymphocytes. the bacterium induces in vitro only a slight proliferation of mononuclear cells and inhibits the spontaneous igg synthesis. in order to characterize these effects, the o-chain of the lipopolysaccharide of brucella melitensis (a polysaccharide consisting of poly-4,6-dideoxy-4-formamido-alpha-d-mannoside) was prepared and its influence on lymphocyte functions tested. this compound had no effect on blast transformation whereas igg synthesis ... | 1988 | 3266469 |
| brucellosis in the upper nile region--melut district, sudan (report). | in the melut district, south sudan human and animal blood samples were investigated for brucella abortus and brucella melitensis. 9.2% of the investigated cattle and 16.2% of the green long-tailed monkies were brucella abortus-positive. school children revealed a 3.7% positivity rate, melut's hospital patients 5.2% and village children and adults 2.2%. however, only a small number of hospital patients was investigated. a small percentage of sheep and goats was investigated for brucella melitensi ... | 1988 | 3275090 |

| risk of infection by brucella melitensis for people living near infected goats. | taking advantage of a local outbreak of brucellosis in a herd of goats, we have assessed the risk of infection for people living nearby. by means of serological tests we have shown that such a risk is small provided that direct contact with contaminated tissues or secretions of goats is avoided. | 1987 | 3312421 |
| [endocarditis with unusual causative agents]. | in the period 1947-1985, 601 patients with infective endocarditis were seen at the university hospital zurich and the kantonsspital lucerne. streptococci, enterococci and staphylococci were the predominant causative organisms in two-thirds of all cases. in more than 25% of the patients blood cultures remained negative. in 6 patients endocarditis was caused by very rare organisms, viz. coxiella burnetii (2 cases), hemophilus parainfluenzae, corynebacterium bovis (diphtheroids), brucella melitensi ... | 1987 | 3324331 |
| acute brucella ileitis. | human brucellosis is an enteric fever in which systemic symptoms are generally more prominent than gastrointestinal complaints. during an outbreak of infection caused by brucella melitensis, linked to ingestion of unpasteurized goat milk cheese, we treated a child with radiographic evidence of acute ileitis. alimentary tract involvement in brucellosis is reviewed. | 1988 | 3337066 |
| elisa versus routine tests in the diagnosis of patients with systemic and neurobrucellosis. | sera from patients in different stages of brucellosis as well as sera and cerebrospinal fluid (csf) from patients with central nervous system (cns) brucellosis and controls, were tested by elisa for brucella-specific igg, igm and iga. the results were compared with culture findings, micro-agglutination (ma), slide agglutination with rose bengal (rb), and brucella melitensis stained antigens (sa). in sera of patients with acute brucellosis (296), elisa was positive for igm (100%), igg (97%) and i ... | 1988 | 3345262 |
| the characteristics of a variant strain of brucella melitensis rev 1. | circumstantial evidence is presented for the occurrence of a variant of a vaccine strain of b. melitensis rev 1, designated "fsa" (foreign south african). fsa resembles rev 1 in its reactions to penicillin and streptomycin but reacts closer to a field strain of b. melitensis as regards dye (thionine and basic fuchsin) sensitivity and colony size. although colonies of rev 1 were consistently smaller than other b. melitensis strains, their size was 0,75 mm as opposed to the 1-2 mm reported in the ... | 1988 | 3353094 |
| characterization of brucella polysaccharide b. | polysaccharide b was extracted from brucella melitensis 16m and from a rough strain of brucella abortus 45/20 by autoclaving or trichloroacetic acid extraction of whole cells and by a new method involving mild leaching of cells. the material obtained by either of the established procedures was contaminated by o polysaccharide. the new leaching protocol eliminated this impurity and provided a pure glucan, which was regarded as polysaccharide b. this polysaccharide was found by high-performance li ... | 1988 | 3356461 |
| recurrent epidermal cyst infection caused by brucella melitensis in a diabetic patient. | a presternal swelling diagnosed clinically as a sebaceous cyst in a 60-year-old diabetic patient was surgically drained, and the aspirated purulant material yielded growth of brucella melitensis. the swelling recurred four times and was drained on every occasion. the patient responded to surgical excision and antibrucella treatment. the histologic diagnosis was an epidermal cyst. | 1988 | 3384896 |
| probable transmission of brucellosis from breast milk to a newborn. | the first case of neonatal brucellosis is described. the baby was fed breast milk only when the mother became acutely ill with fever, arthralgia and malaise. at the same time the baby was febrile. blood cultures grew brucella melitensis in both mother and child. the brucella agglutination titre in the breast milk was 1:2560. both mother and child recovered during treatment with streptomycin. | 1988 | 3407006 |
| structural elucidation of the brucella melitensis m antigen by high-resolution nmr at 500 mhz. | the brucella m antigen from the species type strain brucella melitensis 16m has been identified as a component of the cell wall lipopolysaccharide (lps). o polysaccharide liberated from this lps by mild acid hydrolysis exhibited m activity in serological tests and was shown to be a homopolymer of 4-formamido-4,6-dideoxy-alpha-d-mannopyranosyl residues arranged in an oligosaccharide repeating unit as judged by sodium dodecyl sulfate-polyacrylamide gel electrophoresis of the native lipopolysacchar ... | 1987 | 3442684 |
