| [pulmonary infection with mycobacterium szulgai]. | mycobacterium szulgai is a newly recognised species of mycobacteria whose pathogenicity in man can only be confirmed following certain criteria. we report a new observation comprising three points of interest. m. szulgai appears to be directly responsible for pulmonary infection and the clinical and radiological progress is very rapid. the human disease probably comes from infected water in aquaria. we have reviewed other cases of m. szulgai in the literature and for two out of three amongst the ... | 1991 | 1857828 |
| structure of mycobacteria: recent developments in defining cell wall carbohydrates and proteins. | work from this laboratory on the immunogens of mycobacterium species has focused on those based on carbohydrates (with a view to the development of specific tools for the serodiagnosis of mycobacterioses) and on the cell-wall proteins, as a source of protective immunity and as a means of observing specific delayed-type hypersensitivity. most mycobacteria are endowed with specific, highly antigenic glycolipids that are powerful for the serodiagnosis of individual mycobacterial infections: e.g., t ... | 1989 | 2469120 |
| infections caused by mycobacterium szulgai in humans. | mycobacterium szulgai is a scotochromogenic species that has recently been recognized as a human pathogen. twenty-four cases of disease caused by m. szulgai in humans have been reported in the english-language literature. the clinical features of these cases were reviewed, and three additional cases (two pulmonary, one extrapulmonary) were studied. pulmonary disease indistinguishable from that caused by mycobacterium tuberculosis was the commonest type of infection caused by m. szulgai (18 of 27 ... | 1987 | 3321362 |
| trehalose-containing lipooligosaccharide antigens of mycobacterium sp.: presence of a mono-o-methyltri-o-acyltrehalose "core". | we have described the surface antigens of mycobacterium kansasii as trehalose-containing lipooligosaccharides (los) which at the nonreducing "epitope" end bear a unique amino sugar containing diglycosyl unit, whereas the putative reducing end consists of an acylated alpha, alpha-trehalose-containing tetraglucosyl "core" [hunter, s. w., jardine, i., yanagihara, d. l., & brennan, p. j. (1985) biochemistry 24, 2798-2805]. the presence of a new variation on this core, in mycobacterium szulgai, is no ... | 1988 | 3365409 |

| trehalose-containing lipooligosaccharides. a new class of species-specific antigens from mycobacterium. | mycobacterium kansasii is characterized by the presence of seven species-specific neutral lipooligosaccharide antigens. all react with hyperimmune anti-m. kansasii serum in enzyme-linked immunosorbent assays, and the more glycosylated members also react by gel diffusion. both the native glycolipids and their inherent oligosaccharides were purified and the major features of their unique structures determined by acetolysis, partial acid cleavage, 1h-nmr and 13c-nmr, and chemical ionization and ele ... | 1983 | 6411715 |
| disseminated mycobacterial disease caused by mycobacterium szulgai. | disseminated mycobacterial disease due to mycobacterium szulgai occurred in a previously healthy young man. the clinical picture included fever, mediastinal and generalized lymphadenopathy, hemoptysis, and skin lesions but was dominated by progressive multifocal osteomyelitis. immunological studies revealed a decrease in t-lymphocyte reaction to mitogens, but this was tested late in the course of the disease and may have been secondary. in spite of repeated surgical drainage and treatment with m ... | 1984 | 6477009 |
| pulmonary infection caused by mycobacterium szulgai. | the first reported case of pulmonary infection in australia caused by mycobacterium szulgai is presented. only 15 other cases are known to have been reported in the literature. all isolates reported so far have been associated with human disease. | 1981 | 7254091 |
| relationship between photochromogenicity and test temperature in mycobacteria. | although it has been recommended that photochromogenicity of mycobacteria should be tested after incubation at 25 to 30 degrees c for 2 weeks (wayne et al., int. j. syst. bacteriol. 24:412-419, 1974), our results indicate that photochromogenicity should be determined at 37 degrees c in the dark and under continuous exposure to light for 2 weeks. the test at 37 degrees c gives more stable results for mycobacterium kansasii, mycobacterium marinum and mycobacterium szulgai. | 1981 | 7276150 |
| the epidemiology of opportunist mycobacterial infections in wales, 1952--1978. | the incidence of infections caused by opportunist mycobacteria in wales during the years 1952--1978 was derived from the records of the mycobacterium reference unit in cardiff. mycobacterium kansasil gave rise to 154 pulmonary and two nonpulmonary infections. most of these patients were middle-aged men, approximately half of whom had pneumoconiosis or occupational exposure to dust. organisms of the mycobacterium avium-intracellulare-scrofulaceum complex caused pulmonary disease in 44 subjects an ... | 1981 | 7339797 |
