[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
[experimental pathogenicity of isolates of nocardia asteroides, nocardia brasiliensis and nocardia caviae from different sources].the experimental pathogenicity of 14 isolates of nocardia brasiliensis, 15 of n. asteroides, and 5 of n. caviae was investigated for the white swiss mice inoculated intraperitoneally and in the foot pad, and for the guinea-pig and the hamster (mesocricetus auratus) both inoculated intratesticularly. the guinea-pig was remarkably sensitive to n. asteroides, with an apparent relationship between pathogenicity and thermotolerance, confirming previous observations. mice were in general less suscepti ...19826760417
[sporotrichoid infection caused by nocardia brasiliensis].a few days after a spine of one of his indoor cacti had pricked the fourth finger of his left hand, a 56-year-old man developed multiple inflammatory suppurating nodules and infiltrates and a cord-like lymphangitis on the left forearm and upper arm. nocardia brasiliensis was cultivated from aspirated pus. subsequently, both nocardia brasiliensis and nocardia asteroides were isolated from the cactus earth. this is the first report of an infection by nocardia brasiliensis acquired in germany.19827152897
enhanced resistance to nocardia brasiliensis infection in mice depleted of antigen-specific b cells.this study deals with the roles of t and b cells in nocardia brasiliensis infection in mice. nocardia injected into the animals' footpads caused inflammatory responses and mycetomas in situ, resulting in granulomatous lesions of subcutaneous tissues and eventual bone destruction. these clinical features resemble those of humans infected with nocardia. the effect, if any, of antibody was studied by passively transferring anti-nocardia serum into either immunologically normal or t-deficient infect ...19826980947

numerical and chemical classification of nocardia amarae.twenty-one strains of nocardia amarae and marker cultures of mycobacterium, nocardia, rhodococcus and the 'aurantiaca' taxon were subjected to numerical phenetic analyses using 92 unit characters. the data were examined using the simple matching (ssm), jaccard (sj) and pattern (dp) coefficients and clustering was achieved using the unweighted average linkage algorithm. neither cluster nor aggregate cluster composition was markedly affected by the coefficient used or by test error, estimated at 1 ...19827119738
nocardia brasiliensis: mycetoma induction and growth cycle.the capacity of nocardia brasiliensis to induce mycetoma in balb/c mice in the absence of adjuvants was studied. whether the virulence of n. brasiliensis varied in the different phases of its growth cycle was also determined. the results showed that n. brasiliensis suspended in 0.15 m nacl and injected into the footpads of mice were able to induce mycetoma after only 14 days of infection, as evidenced by histological studies. data are also presented indicating that the virulence of n. brasiliens ...19827152671
[fatty acid composition of the lipids of streptomycetes and their nocardia-like mutants].the models "population--nocardia-like spontaneous mutants" for 14 cultures of streptomycetes and streptoverticillium were used to assess the fatty acid composition of lipids as a criterion for generic differentiation of streptomyces and nocardia cultures. the composition of fatty acids in the nocardia-like mutant str. kanamyceticus ria-771 was found to be identical with that of nocardia asteroides ria-43 and nocardia brasiliensis ria-440, i. e. generic chemotaxonomic traits "overlapped" in the p ...19806777646
experimental production of actinomycetoma in balb/c mice.chronic actinomycetoma associated with grain production was induced in balb/c mice by subcutaneous inoculation of live nocardia brasiliensis in freund incomplete adjuvant into the hind footpads. similar inoculation of n. asteroides and n. caviae resulted in local tumor formation which healed spontaneously after 5 months, the disease disseminating into the peritoneum, where masses or organisms could be detected. grains were recovered from superficial skin lesions of n. caviae, but not from the n. ...19807429630
nocardia brasiliensis in a horse with pneumonia and pleuritis.a 15 month-old quarter horse colt developed severe bacterial pneumonia and effusive pleuritis. a beta-hemolytic streptococcus was isolated from a tracheal wash specimen but the colt died despite conventional therapy. the gross post mortem and histologic lesions were characteristic of pulmonary nocardiosis. nocardia brasiliensis was isolated from the lung and bronchial lymph node.19807460568
resistance to nocardia brasiliensis infection in mice immunized with either nocardia or bcg.different vaccination procedures to increase the mechanisms of host resistance to nocardia brasiliensis were studied in mice. when mice were challenged in the footpad, 2 x 10(8) n. brasiliensis 20 days after footpad inoculation with either viable or killed n. brasiliensis, the mice demonstrated significant resistance to infection when compared with noninfected and nonimmunized mice. the degree of resistance seems to be correlated with the delayed-type hypersensitivity response in the vaccinated ...19807393313
an ultrastructural comparison of the cell envelopes of selected strains of nocardia asteroides and nocardia brasiliensis.growth curves were determined for three strains each of nocardia asteroides and nocardia brasiliensis. two strains of n. brasiliensis and one strain of n. asteroides had longer lag periods of growth than the remaining three strains. all strains had generation times of approximately 5.5 hours. the ultrastructure of the cell envelope of each nocardia strain in early stationary phase growth was also examined. all the strains had typical trilaminar cell walls and cell membranes. the thickness of the ...19806990267
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
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
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
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

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
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
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
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
disseminated nocardia brasiliensis infection.we report a 40-year-old man with advanced hodgkin disease who received combination chemotherapy and developed disseminated nocardia brasiliensis infection. we discuss opportunistic infections in the compromised host, with particular reference to nocardial disease and certain biologic characteristics of that organism.19761259450
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

serological reactions to nocardia antigens.sera from 23 patients with nocardiosis were tested for the presence of precipitating antibodies against an extract of nocardia asteroides. sera from nine of 20 patients infected with nocardia asteroides and one of three sera from patients with nocardia brasiliensis produced one to three precipitin lines with the antigen. sera from eight of 55 patients with tuberculosis and 11 of 13 patients with leprosy also contained nocardia precipitins. none of 33 sera from patients with cryptococcosis, blast ...19751098461
fusion of normal rabbit alveolar macrophages induced by supernatant fluids from bcg-sensitized lymph node cells after elicitation by antigen.cell-free supernatant fluids obtained from bcg-sensitized lymph node cells (6 x 10(6) cell/ml) incubated in tissue culture flasks containing heat-killed bcg (5 mug/ml) induced extensive development of multinucleated giant cells when incubated with normal alveolar macrophages. in contrast, supernatant fluids obtained after incubation of similar samples of the same lymph node cell population in flasks with (i) no mycobacteria, (ii) heat-killed escherichia coli, or (iii) heat-killed bacillus subtil ...19744131544
