isolation and identification of mycobacteria from porcine tissues: a three-year summary.mycobacteria were isolated from 1,591 (78%) of 2,036 porcine tissues submitted to veterinary services laboratories over a 3-year period (july 1, 1971, to june 30, 1974). the isolates were identified by biochemical and serologic tests. of the 1,547 mycobacterium avium isolates, 452 were serotype 1, 728 were serotype 2, 60 were serotyped 4, 110 were serotype 8, and 51 were serotyped 10; 36 isolates represented 11 other serotypes; 65 isolates shared antigens with more than one serotype; and 45 isol ...19751099946
[ofloxacin in the treatment of pulmonary changes caused by mycobacterium avium and mycobacterium xenopii].two cases of atypical mycobacterial infections are reported. the first caused by mycobacterium avium in a patient with silicosis, the second by mycobacterium xenopii in a subject with evidence of extensive post-tuberculosis pulmonary lesions. both were treated with ofloxacin with good results.19921290992
[extracellular and intracellular activity of sparfloxacin against mycobacterium avium complex and mycobacterium xenopi].activity of the new fluoroquinolone sparfloxacin against 30 strains of m. avium complex and 25 strains of m. xenopi was tested in vitro. sparfloxacin was used alone (determination of mics and mbcs) and in combination with ethambutol and rifabutin. synergy studies with determination of the fic and fbc indices showed that the sparfloxacin-ethambutol combination was synergistic against 10 m. avium complex strains and 12 m. xenopi strains. with the three-drug combination (sparfloxacin-ethambutol-rif ...19921323093
identification of mycobacterium avium complex strains and some similar species by high-performance liquid chromatography.strains of mycobacterium avium, mycobacterium intracellulare, mycobacterium scrofulaceum, mycobacterium xenopi, and mycobacterium gordonae were identified by high-performance liquid chromatography (hplc) analysis of mycolic acids as bromophenacyl esters. hplc criteria were used to develop a flow chart identification scheme, which was evaluated in our laboratory with a set of 234 strains representing five species and a hitherto undescribed species. correct identifications of m. gordonae and m. xe ...19921400970
rapid differentiation of mycobacterium xenopi from mycobacteria of the mycobacterium avium-intracellulare complex by pyrolysis mass spectrometry.thirty four cultures of slow growing, tween-80 negative mycobacteria were analysed by pyrolysis mass spectrometry. the results showed that pyrolysis mass spectrometry could positively distinguish strains of mycobacterium xenopi from those of the mycobacterium avium-intracellulare (mai) complex. pyrolysis mass spectrometry may be a useful technique for the rapid characterisation of non-tuberculous mycobacteria in such clinical settings as their isolation from immunocompromised patients-for exampl ...19921577977

activities of pefloxacin and ofloxacin against mycobacteria: in vitro and mouse experiments.the minimal inhibitory concentrations for 90% of strains (mic90) of ofloxacin against mycobacterium tuberculosis and mycobacterium xenopi was 2 mg/l. this was three dilutions lower than that of pefloxacin and was well within the range of drug concentrations achievable in man. the antituberculosis activities of both quinolones were independent of resistance of the strains to other antimycobacterial agents. mycobacterium avium-intracellulare was resistant to both compounds with mic90s greater than ...19911909062
effect of anorexia nervosa on pulmonary immunocompetence.pulmonary infection due to opportunistic organisms and usually nonpathogenic mycobacteria may occur whenever immune defenses are weakened by external factors. these factors include neutropenia, treatment with corticosteroids or cytotoxic agents, previous antibiotic therapy, and nosocomial hazards (eg, catheters, ventilators). nutritional deprivation is also often implicated as an important coexistent variable. an infection due to mycobacterium xenopi (usually a nonpathogenic mycobacterium) in a ...19911925716

isolation of mycobacterium xenopei from water increase in the number of isolations of mycobacterium xenopei from sputum suggested environmental contamination. the organism was recovered from water taps in 61 of 111 pairs of hot and cold water taps in one hospital, 20 of the 74 pairs in another hospital, but from only 3 of 61 pairs of taps in a third hospital and two of 34 pairs in private houses. scotochromogens were recovered from taps in the first two hospitals only, and m. kansasii was isolated twice from the same tap in the first hos ...19705266590

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 ...19817339797

clinical and immunologic response to antigen-specific transfer factor in drug-resistant infection with mycobacterium xenopi.the administration of transfer factor obtained from three donors who had recovered from clinical infections with mycobacterium xenopi to a patient who had a destructive pulmonary infection with this organism, was associated with the reversal of an unfavorable clinical course. cavitary tuberculosis associated with resistance to all combinations of antituberculosis drugs was probably related to a concurrent depression of cell-mediated immunity of unknown origin. antigen specific but not nonspecifi ...19836184988
laboratory and clinical evaluation of mycobacterium xenopi isolates.mycobacterium xenopi and mycobacterium avium complex (mac) are biochemically similar. to define the laboratory characteristics of m. xenopi that distinguish it from mac, 53 m. xenopi isolates from different areas in the united states and 47 isolates recovered at one hospital were evaluated by 13 biochemical tests, accuprobe mac (gen-probe, inc., san diego, ca, usa), colony morphology, formation of x-colonies, pigmentation in response to light, growth on macconkey agar without crystal violet, and ...19957554801

water-borne mycobacterium xenopi--a possible cause of pulmonary mycobacteriosis in the years 1980-1983 m. xenopi was isolated from the sputum of 37 persons, 30 of them living in the agglomeration of the regional town in the region of northern bohemia with 1,175,000 inhabitants. only 7 of these 30 had manifestation of pulmonary disease. m. xenopi was found repeatedly in the sputum in 5 patients out of 7 affected and in 2 out of 23 persons who showed no signs of a disease. the prevalence was in males between the age of 52-67 years. all of them suffered from other diseases, as ...19863805713
structural elucidation of novel methylglucose-containing polysaccharides from mycobacterium xenopi.the structures of methylglucose-containing polysaccharides (meglc ps) from mycobacterium xenopi were investigated using high-ph anion-exchange chromatography and liquid secondary-ion mass spectrometry. we report the structure of two novel meglc ps, referred to as a and b. meglc ps a is composed of 16 d-glucopyranose residues, 11 of which are methylated, and meglc ps b contains 15 d-glucopyranose residues, 10 of which are methylated. the main structural feature of both meglc ps a and b, compared ...19957588770
comparative in-vitro activities of the new quinolone, bay y 3118, and ciprofloxacin, sparfloxacin, tosufloxacin, ci-960 and ci-990.the in-vitro activity of the new quinolone, bay y 3118, was compared with that of ciprofloxacin, tosufloxacin, sparfloxacin, ci-960 and ci-990 against 1640 isolates belonging to 117 bacterial species. against members of the enterobacteriaceae, bay y 3118 was as active as ci-960 and ci-990, up to four-fold more active than ciprofloxacin and tosufloxacin and up to 16-fold more active than sparfloxacin. the majority of enterobacteriaceae which were resistant to ciprofloxacin (mics > or = 2 mg/l) we ...19937605398
