| in vitro susceptibility of mycobacterium fortuitum to n-formimidoyl thienamycin and several cephamycins. | the comparative in vitro activity of n-formimidoyl thienamycin, cefmetazole, cefoxitin, cefotetan (ym-09330), and moxalactam against 13 isolates of mycobacterium fortuitum was evaluated by agar dilution susceptibility testing. n-formimidoyl thienamycin inhibited 10 to 12 strains at 6.25 micrograms/ml, cefmetazole inhibited 12 of 13 strains at 12.5 micrograms/ml, cefoxitin inhibited 11 of 13 strains at 25 micrograms/ml, and cefotetan inhibited 11 of 13 strains at 50 micrograms/ml. moxalactam was ... | 1982 | 6961887 |
| comparative studies of antigen 21 in mycobacterium and nocardia species: possible taxonomic relationships with mycobacterium leprae. | studies of mycobacterium leprae, mycobacterium tuberculosis and nocardia caviae in comparison with each other and with other mycobacterium and nocardia species were performed on the basis of antigen 21 intramolecular heterogeneity. three different antisera were used: rabbit anti-mycobacterium smegmatis antiserum, rabbit anti-nocardia asteroides antiserum, and a lepromatous serum pool. with reference to each of the three antiserum sources used the strains were ranked in an order of relatedness or ... | 1980 | 7002798 |
| infection of bone by mycobacterium fortuitum masquerading as nocardia asteroides. | a case of traumatic osteomyelitis of the leg yielded on culture a branching partially acid-fast organism that failed to respond to therapy directed at nocardia asteroides. subsequent laboratory investigation revealed the organism to be mycobacterium fortuitum. n. asteroides and m. fortuitum can demonstrate similar staining and morphologic patterns microscopically, as well as common colonial and cultural characteristics. separation can be aided by careful examination of the branching pattern, and ... | 1981 | 7023228 |
| mycobacterium fortuitum pulmonary infection associated with an antigen-selective defect in cellular immunity. | in this study we describe the first example of a well documented case of pulmonary infection caused by mycobacterium fortuitum shown to be associated with an antigen-selective defect in cell-mediated immunity to this organism. immunologic parameters were evaluated before, during and after antibiotic treatment with amikacin. a defect in cellular immunity to purified protein derivative from myco. fortuitum, shown to be antigen-selective as indicated by normal responsiveness to purified protein der ... | 1981 | 7025623 |
| identification of clinically significant mycobacterium fortuitum complex isolates. | recent outbreaks of nosocomial infections caused by organisms identified as the mycobacterium fortuitum complex suggest that species and subspecies identification is epidemiologically important. in a study of 170 strains, m. fortuitum was differentiated from m. chelonei by nitrate reduction and iron uptake. m. fortuitum was further divided into biovariant fortuitum, biovar peregrinum, and an unnamed third biovar by inositol and mannitol utilization. m. chelonei was further divided into subsp. ch ... | 1981 | 7037841 |

| optimization and kinetics of in vitro stimulation of carp (cyprinus carpio l.) leukocytes. | the optimization of a leukocyte stimulation microassay with carp (cyprinus carpio l.) leukocytes is described. leukocytes were isolated from the thymus, anterior kidney, spleen, mid-kidney and peripheral blood. leukocyte cultures were stimulated with pha-p, lps (escherichia coli 055: b5) pwm, cona and ppd from mycobacterium fortuitum. the optimum incubation temperature for leukocyte cultures differed 3.5 days for leukocyte cultures derived from lymphoid organs and 4.5 days for peripheral blood l ... | 1982 | 7051523 |
| mycobacterium fortuitum as a cause of mastoiditis and wound infection. | mycobacterium fortuitum is uncommonly pathogenic for man. when implicated, this organism usually infects soft-tissue structures. therapy necessitates surgical excision and prolonged antimicrobial therapy. a patient had a mastoiditis and wound infection due to this organism. her successful treatment included radical debridement and prolonged therapy with several antimicrobials. the necessity for including mycobacteria in the differential diagnosis of ear, nose, and throat diseases is emphasized b ... | 1982 | 7053742 |

| microbial degradation of the phytosterol side-chain to 24-oxo products. | a mutant of the potent sterol degrader mycobacterium fortuitum (atcc 6842) has been isolated which is defective in its ability to degrade both the steroid nucleus and sterol side-chains that are branched at the 24-position. bioconversions of phytosterol mixtures by this mutant resulted in the accumulation of the novel 24-oxo intermediates 9-hydroxy-27-nor-4-cholestene-3,24-dione (ii) and 9-hydroxy-26,27-dinor-4-cholestene-3,24-dione (iii). under the same conditions, cholesterol is degraded mainl ... | 1980 | 7210061 |
| the embolization of bone wax from sternotomy incisions. | we discuss our study on the effects of discontinuation of the usage of bone wax as a hemostatic agent in sternotomy incisions. in 1976, we abandoned use of bone wax because it was suspected of causing several cases of mycobacterium fortuitum sternal osteomyelitis. in a retrospective study involving 400 patients, we found that this step did not increase postoperative bleeding as measured by drainage from the chest tube and by the need to return patients to the operating room because of bleeding. ... | 1981 | 7212838 |
