Potentiation of antibiotic bactericidal activity by normal human serum.
Combinations of certain antibiotics and normal human serum at concentrations at which there was no killing by the agents when used alone were found to be bactericidal for Escherichia coli K-12 cells. This effect was observed with tetracycline, streptomycin (SM), trimethoprim, and ampicillin, but not with chloramphenicol or nalidixic acid. Synergy between SM and human serum was also observed aga...
متن کاملThe Bactericidal Action of Human Serum on Hemolytic Streptococci
Aerobic Tests. Changes in pH Which Occurred during Incubation.-(a) The pH of sterile specimens of both normal and patients' sera increased, during 24 hours incubation, from 8.0-8.8 up to 9.2-9.6. (b) The pH of patients' sera, inoculated with hemolytic streptococci, progressed in the alkaline direction as did the sterile specimens. (c) The pH of normal sera, inoculated with hemolytic streptococc...
متن کاملResistance of Gardnerella vaginalis to bactericidal activity of human serum.
To assess the sensitivity of Gardnerella vaginalis to the complement mediated bactericidal activity of serum, six laboratory strains were incubated with normal human serum and two strains freshly isolated from women with non-specific vaginitis (NSV) were each incubated with homologous patient serum. There was no significant difference between the number of organisms recovered from unheated or h...
متن کاملSerum Bactericidal Resistance in Uropathogenic E.coli
Urinary tract infections(UTIs) are among the most common bacterial infections encountered in clinical practice (Ejrnaes, 2011)) E.coli causes about 80%of acute UTIs(Mitsumori,1998).E.coli is the most prevalent facultative gram negative bacilli in the human fecal flora, usually inhabits the colon as an innocuous commensal (Johnson, 1991). E.coli strains causing disease outside the gastrointestin...
متن کاملEffects of penicillinase on bactericidal and complement activities in normal human serum.
During routine addition of penicillinase (beta-lactamase) to patients sera, we found that the capacity of some of these sera to kill serum-sensitive gram-negative organisms was significantly decreased. Further controlled studies showed that penicillinase decreased both the bactericidal activity of normal human sera and the total hemolytic activity (CH50) of complement in these sera. The decreas...
