Propolis is a substance produced by honeybees. It is inhibitory to some bacteria species, mainly Gram-positive bacteria, but less inhibitory to Listeria monocytogenes (L.m) than to the other Gram-positive bacteria tested. In order to obtain selective growth of L.m. from contaminated samples, the effect of propolis in plating media and broths on various strains of bacteria was examined. Table I shows the effect of increasing concentrations of propolis in tryptose-agar (TA). L.m. tolerated higher concentrations of propolis than Streptococcus viridans and Staphylococcus aureus. L.m. grew well in tryptosebroth (TB) that contained 0.15 mg propolis pr. ml medium, while Streptococcus viridans and Streptococcus agalactiae were completely inhibited as seen in Table II. Table III shows that when serum was added to the agar, the inhibitory effect was reduced. It can also be seen that Gram-negative bacteria grew quite well on media that contained 0.19 mg propolis pr. ml. To reduce the growth of Gram-negative bacteria, nalidixic acid was added to the medium. Table IV illustrates growth of various species of bacteria in tryptosephosphatebroth (TFB) with or without propolis and nalidixic acid. Most of the strains tested were inhibited, but Pseudomonas aeruginosa and to some extent faecal streptococci were able to grow in the medium that contained the selective substances. As a conclusion it seems that propolis may be a valuable additive to a medium for the selective isolation of L.m. 相似文献
