[Comparative evaluation of the antibacterial activity of aminoglycosides by means of microcalorimetry].
Possible use of microcalorimetry for comparative investigation of antibiotics is exemplified by estimation of the kinetics of the antibacterial effect of netilmicin, sisomycin and gentamycin sulfate on moderately sensitive strains of E. coli and P. aeruginosa. It is suggested that the area under the curve of the kinetics of the rate of heat release by the bacterial cultures in the presence of antibiotics be used as a parameter characterizing the integral antibacterial effect. The parameter was used for demonstrating the differences in the antibacterial action of netilmicin, sisomycin and gentamycin sulfate on the strains tested with application of various inoculum sizes and antibiotic concentrations.
