Reduction effect of royal jelly and rape honey alone and in combination against methicillin-resistant Staphylococcus aureus (MRSA) strains

Abstract

Multidrug resistant and methicilin-resistant Staphylococcus aureus (MRSA) is involved in severe difficult to treat skin and soft tissue infections in humans. In the present study the antibacterial reduction effect of royal jelly (RJ), rape honey (RH), as well as in combination (RJ:RH, 1:100 w/w) against multidrug resistant MRSA strains was evaluated by means of a microbiological method "in vitro". Royal jelly and rape honey mixture possessed a higher antibacterial activity than rape honey. The concentrations of royal jelly (20 and 30% v/v) had a total inhibitory effect against tested MRSA strains. Royal jelly alone and in rape honey mix (RJ:RH, 1:100 w/w) have a potential as alternative therapeutics against MRSA strains, resistant for antibiotics.
