b-lymphocyte activation with an extract of nocardia brasiliensis.an extract from the pathogenic actinomycete nocardia brasiliensis was mitogenic for murine lymphocytes. this deoxyribonucleic acid-synthetic response of whole spleen cells peaked after 48 h in culture at concentrations of nocardia extract ranging from 10 to 200 micrograms/ml. the extract appeared to be a mitogen for b lymphocytes since cultures of spleen cells from congenitally athymic nude (nu/nu) mice and of antithymocyte serum plus complement-treated spleen cells from conventional (+/+) mice ...1979314931
nocardia infections in congenitally athymic (nude) mice and in other inbred mouse strains.the mortality rate and histopathological features of nocardia asteroides and nocardia brasiliensis infections in congenitally athymic (nude) mice of icr and c3h/eb origins were quite different from what we found for swiss white mice and other inbred mouse strains (namely, c57/bl/6j, new zealand black, balb/c, cba/lac, and c3h/eb). the immunocompetent littermates of the congenitally athymic mice occupied an intermediate position between their athymic siblings and swiss white mice in terms of thei ...1977336547
preliminary investigation of the use of the enzyme linked immunosorbent assay (elisa) in the serodiagnosis of mycetoma.antibody levels in a small group of sudanese patients with clinically diagnosed mycetoma, and control groups were measured by countercurrent immunoelectrophoresis (cie) and enzyme linked immunosorbent assay (elisa). antigens were prepared from the following organisms: streptomyces somaliensis, actinomadura madurae, a. pelletieri, nocardia brasiliensis and madurella mycetomi. positive reactions were obtained in clinical cases against the homologous antigens in both cie and elisa; all heterologous ...1978360443
primary cutaneous nocardiosis.seven patients with primary cutaneous nocardiosis were seen during a 20-month period. six patients had a history of local trauma to an extremity or did frequent yard work. the spectrum of clinical disease included cellulitis, pustules,pyoderma, or lymphocutaneous syndrome mimicking sporotrichosis. evidence of nocardia infection elsewhere was absent, and no patient had a serious underlying disease. nocardia brasiliensis was isolated from four cases, and n asteroides was identified in the other th ...1979376887
changes in host resistance caused by nocardia brasiliensis in mice: cross-protection against listeria monocytogenes.listeria monocytogenes was used to study the rate of development, magnitude, and persistence of the antimicrobial resistance engendered by nocardia brasiliensis infection in mice. the growth of listeria in the liver and spleen was more effectively restricted in nocardia-infected mice than in noninfected animals. the development of delayed-type hypersensitivity to the nocardia antigen was closely correlated to the increased resistance to listeria, suggesting that both properties are the consequen ...1978640748
nocardia asteroides and nocardia brasiliensis infections in mice.a model for nocardia asteroides and nocardia brasiliensis infections in swiss white mice has been established without the addition to the inocula of any form of adjuvant. serial histopathological studies revealed that these two actinomycetes cause lesions that are quite different in their features. an acute suppurative abscess characterizes the lesions of n. asteroides. in the case of n. brasiliensis infections a granuloma is produced in which a striking feature is the presence of large numbers ...1976773837
different degrees of morbidity, in the white mouse, induced by nocardia brasiliensis, nocardia asteroides and nocardia caviae.the respective degrees of morbidity induced by 6 strains each of nocardia brasiliensis, n. asteroides and n. caviae were investigated by the method of inoculation in the plantar pad of the white mouse, using a suspension of these nocardiae at a concentration of 10 mg/0-1 ml., and inspecting the animals one month, two months and three months following inoculation. all of the strains of n. brasiliensis produced attack greater and more consistent than that of the other species, n. caviae and n. ast ...1976793053
lymphocutaneous nocardiosis due to nocardia brasiliensis.a farmer had chaining lymphocutaneous granuloma on the right hand and arm. clinically the syndrome seemed typical for sporotrichosis. bacteriological examination revealed nocardia brasiliensis as the only etiologic agent. since 1920, eight similar cases of sporotrichoid nocardiosis have been reported from various parts of the world. to our knowledge, isolation of n brasiliensis has not been reported previously in this geographical area.1977856052
amyloidosis developing in experimental nocardia infections.swiss white and c57/bl/6j mice inoculated repeatedly with either nocardia asteroides or nocardia brasiliensis organisms developed amyloidosis over a 7-month period. amyloidosis also developed in these mice within 6 weeks following a single large inoculum of either organism, but not in other in-bred mouse strains, suggesting a genetic influence in the pathogenesis of this form of secondary amyloidosis.1977861163

sensitivity to capreomycin and prothionamide in strains of mycobacterium, nocardia, rhodococcus, and related taxa for taxonomical purposes.sensitivity to capreomycin and to prothionamide was analysed for 150 strains belonging to the genera mycobacterium, nocardia, rhodococcus, and related taxa. the analyses showed, e.g., that strains of mycobacterium chelonei and nocardia brasiliensis were more resistant to capreomycin than the other strains tested and that m. farcinogenes differed from m. senegalense concerning sensitivity to this drug. the analysis showed, furthermore, that strains of mycobacterium differ from those of nocardia, ...19836196927
failure of sulfonamides and trimethoprim in the treatment of nocardiosis.an immunocompromised patient with nocardia brasiliensis pneumonia and empyema acquired disseminated disease due to nocardia asteroides and died. the treatment of choice for pulmonary or disseminated nocardiosis is 6 to 12 g/day of sulfisoxazole (or adjusted dosage to achieve a serum level of 100 to 150 mg/l) continued for six to 18 months. combination therapy may be beneficial in selected patients; if trimethoprim therapy is used with sulfonamides, higher than usual doses of trimethoprim may be ...19836337576
purification and partial characterization of a nocardia brasiliensis extracellular protease.nocardia brasiliensis possess proteolytic activities that can be readily detected in a variety of media. in a modified formulation of a growth medium originally used for streptomyces aureofaciens, n. brasiliensis was found to secrete proteolytic enzymes, one of which was capable of hydrolyzing casein. this enzyme was purified to homogeneity from cell-free culture filtrates of n. brasiliensis. the purification procedure included ion-exchange chromatography on carboxymethyl-sepharose, gel filtrati ...19846363390
[mycetoma in northern argentina].from 1972 to october 1982 we have observed 39 cases of mycetoma in the skin department of the hospital del milagro, salta (argentina). the diagnosis was based on the clinical aspect, mycological studies and in most cases histopathology was done as well. the mayoritary of the patients were farmers. from the clinical point of view there si a true prevalence of nocardia brasiliensis. most of the mycetomas can be found in the lower limbs. some of the patients presented quite severe lesions and eight ...19836366400

the clinical spectrum of nocardia brasiliensis infection in the united states.seven cases of infection due to nocardia brasiliensis were identified over a 13-year period at duke university medical center, durham, north carolina. these seven cases and a review of 55 cases in the literature reported from the united states show that n. brasiliensis can cause a wide spectrum of disease. forty-six of the 62 patients had disease of skin and soft tissues. cutaneous manifestations included cellulitis, pustules, ulcerations, pyoderma, subcutaneous abscesses, a lymphocutaneous synd ...19846374833
disseminated cutaneous nocardia brasiliensis infection.nocardia brasiliensis is an uncommon pathogen in the united states despite its presence in soil samples. it is most frequently seen in patients who are immunosuppressed, but can occur in the immunocompetent host also. usually in a healthy host the infection is localized to one area of the body. disseminated infection was diagnosed in a healthy child who recovered fully after initiation of oral sulfonamide therapy. we suspect that the source was soil to which the patient was exposed during a fami ...19846504778
