bacteriology of the human biliary tract and the duodenum.using the modern anaerobic transport media and meticulous culture techniques, 74 patients undergoing biliary tract surgery were studied. the biliary system was found to be sterile in 58 patients (78%). fifteen patients had 35 isolates of aerobic and facultative bacteria. the most common ones were klebsiella, enterococcus, and escherichia coli. the only anaerobe isolated was clostridium perfringens. eight of 17 patients (47%) with acute cholecystitis and five of 49 patients (10%) with chronic cho ...1977195558
cutaneous abscesses. anaerobic and aerobic bacteriology and outpatient management.specimens from 135 cutaneous abscesses in outpatients were cultured anaerobically and aerobically. of these, 4% were sterile and 29% yielded pure cultures, predominantly of staphylococcus aureus. aerobic species were isolated from all anatomic areas. anaerobes were found with a frequency comparable to aerobes in all nonperineal areas except the hand. in contrast, abscesses in the perineal region contained a greater variety and frequency of anaerobes. only two patients were febrile. all abscesses ...1977196534
polymorphonuclear leukocyte bactericidal activity and oxidative metabolism during glutathione peroxidase deficiency.glutathione peroxidase (gpx) deficiency has been proposed as a cause of some instances of chronic granulomatous disease (cgd). gpx activity varies greatly among species, and specific deficiency of this selenium-dependent enzyme can be produced by dietary selenium deficiency in rats. bactericidal activity of polymorphonuclear (pmn) leukocytes from normal rats, humans, and guinea pigs (gpx high, intermediate, and nearly absent, respectively), selenium-deficient rats (gpx absent), and a patient wit ...1977198376
[adjuvant activity of gram-negative bacteria and their structural components (author's transl)].regarding the adjuvant activity of gram-negative bacteria we have to distinguish at least 4 different potencies, i.e., 1) increase in the production of circulating antibodies during the primary and secondary immune responses; 2) induction of susceptibility to systemic anaphylaxis; 3) prompt production of experimental "allergic" diseases, and 4) increase in resistance to infections. although all gram-negative bacteria contain several structural components with adjuvant potencies, the immunopotent ...1977199540
[fluorescent fab-fragments of antibodies. comparative assessment and utilization in immunofluorescent analysis].the authors present the results of a comparative study of the immunofluorescent activity and the specificity of fluorescent fab-fragments of antibodies to r. prowazeki, d. sibericus, and b. pertussis obtained by the enzymatic hydrolysis of specific immunoglobulins with papain. fluorescent fab-fragments of antibodies possessed the same sensitivity and specificity as the homologous fluorescent antibodies, but had an advantage of a much weaker capacity to nonspecific fluorescence and a relatively h ...1977203147
thermal regulation of the fatty acid composition of lipopolysaccharides and phospholipids of proteus mirabilis.the fatty acid composition of the lipid a moiety of the lipopolysaccharide and phospholipid fractions of proteus mirabilis changed significantly on varying the growth temperature. a decrease in the growth temperature from 43 degrees c to 15 degrees c resulted in a decrease in the palmitic acid content of the lipopolysaccharide from 19.4% of total fatty acids at 43 degrees c to 1.4% at 15 degrees c, and by the appearance of an unsaturated fatty acid residue, hexadecenoic acid. changes in the 3-hy ...1978206438
