Plant polyextracts against avibacterium paragallinarum and pasteurella multocida, causual agents of respiratory syndrome in chickens.

Abstract

The present investigation evaluates the capacity for in vitro growth inhibition of the casual agents of chronic respiratory syndrome among chickens, the bacteria Avibacterium paragallinarum and Pasteurella multocida, for the ethanolic plant extracts of the following plants: cinnamon (Cinnamomum verum), oregano (Origanum vulgare), redbird flower/ítamo/zapatilla del diablo (Euphorbia [Pedilanthus] tithymaloides), bougainville (Bougainvillea glabra Choisy), sierrecilla (Mimosa lacerata) and eucalyptus/Tasmanian bluegum (Eucalyptus globulus). From the ethanolic extracts, the phytochemical composition of the samples was determined, using chromogenic agents. Found were tannins, flavonoids, triterpenes, phenolic compounds and alkaloids.
