The objective was to demonstrate the effect of the infusions of Cymbopogon citratus (DC.) Stapf., Plectra thus amboinicus (Lour.), Tilia cordata (Mill.), in the drinking water of broiler chickens Cobb 500, as well as pure leaf extract of Plectranthus amboinicus (Lour.), Lippia alba (Mill.) and Ocimun bacilicum (L.), for the control of E. coli. In base of the results it can be concluded there is an effect on the inoculated E. coli when the infusions were offered to broiler chickens, and that the extracts used in this research were efficient at laboratory level to inhibit bacterial growth in a selective growth medium.Reserva de todos los derechosInfusionPure extractColimetryMac Conkey AgarArtículoAbierto
