IN VITRO ACTIVITY OF PROPOLIS AGAINST BACTERIAL AND YEAST PATHOGENS ISOLATED FROM HUMAN INFECTIONS J. Venom. Anim. Toxins
FERNANDES Jr.,A.; SUGIZAKI,M.F.; FOGO,M.L.; FUNARI,S.R.C.; LOPES,C.A.M..
The in vitro activity of propolis against 118 Staphylococcus aureus, 108 Escherichia coli, 60 Salmonella typhimurium, 50 Candida albicans, 23 Candida parapsilosis, 19 Candida tropicalis and 14 Candida guilliermondii isolated from human infections was studied by the agar dilution method. Among the bacteria, the Gram-negative were the least susceptible organisms showing minimal inhibitory concentration (MIC) for 90% of the strains tested ranging from 22.5 mg/ml - 10,2% V/V to 23.1 mg/ml - 10.5% V/V. The MIC's for Candida ranged from 0.80 mg/ml to > 11 mg/ml (0.40% V/V to > 5.0% V/V), the strains of C. parapsilosis being the least susceptible. The relative order of susceptibility among all isolates, was: S.aureus > C. tropicalis >...

POPULATION ANALYSIS OF SUSCEPTIBILITY TO PROPOLIS IN REFERENCE STRAINS OF Staphylococcus aureus AND Escherichia coli J. Venom. Anim. Toxins
FERNANDES Jr.,A.; LOPES,C. A. M.; SFORCIN,J. M.; FUNARI,S.R.C..
Susceptibility to several ethanolic extracts of propolis (EEP) concentrations was tested with the population analysis technique in reference strains of Staphylococcus aureus (ATCC 25923) and Escherichia coli (ATCC 35218). The results of these tests showed that all bacteria were killed by EEP concentrations approximately equal or higher (2.0% v/v- S. aureus; 10.0% v/v - E. coli) than the respective minimal inhibitory concentrations (MIC). Regarding the susceptibility to propolis, there was a homogeneity of data with the respective time kill curves showing a clear bactericidal effect during 6 to 9 h of exposition.
