The Action of Propolis on Certain Microorganisms Isolated from Avarious Mediums

The biological and pharmacological characteristics of propolis, a substance elaborated by Apis mellifera L. from resins of a vegetable origin, have been the object of numerous research studies up to the present. The antimicrobial activity of this beehive product was tested, especially on the bacteria and the fungi which are pathogenous for man and for animals, and rarely, on microorganisms coming from other mediums (PEPELJNJAK et al., 1982; MILENA et al., 1989; BRUMFITT et al., 1990; BRUNELLI et al., 1990; LA TORRE et al., 1990; LORI, 1990; DETOMA and OZINO, 1991; ABD-AL-FATTAH et al., 1993; FERNANDES Jr. et al., 1994). However, the results of these studies bring contradictory information on the sensitive species, as well as on the doses of propolis which are necessary to inhibit the microbial development. Considering all these, researches were effected in order to obtain better knowledge on the action of this natural product on microorganisms of various origins. At the same time, a preliminary study was effected on the possible variability of the propolis action depending on its geographical origin.
