Abstract
The present study aimed to evaluate the efficacy of traditionally used antibacterial plants (Euphorbia prostrata, Schinus molle, Brickellia veronicaefolia and Lepidium virginicum) in Santa Rosa Range in Guanajuato against major mastitis-causing pathogens. The selected plants were phytochemically screened for alkaloids, flavonoids, polyphenols, saponins, anthraquinone, cardiac glycosides, steroids and terpenoids. Moreover, to achieve the main purpose of the present research, extracts of selected plants were tested for in vitro antibacterial activity against Staphylococcus aureus, Escherichia coli, Shigella spp., Bacillus subtilis, Clavibacter spp., Proteus vulgaris and Salmonella spp. All these bacterial were isolated from clinical mastitis in dairy cows. The results indicated that the ethanolic extract of the aerial part of L. virginicum exhibited the strongest antimicrobial activity, and it could be potential candidate specie for the development of novel veterinary drugs with low cost and fewer side effects.
Highlights
Bovine mastitis, an inflammation of the mammary gland caused by bacterial infection, is a highly prevalent disease in dairy cattle characterized by physical, chemical and usually bacteriological changes in milk and by pathological changes in the glandular tissues (LEBLANC et al, 2006)

The ethnobotanical survey results revealed that different medicinal plants were used for recipe formulation for treating various diseases, among them Ephorbia prostrata, Schinus molle, Brickellia veronicaefolia and Lepidium virginicum were most commonly used to treat bacterial infections
Summary
An inflammation of the mammary gland caused by bacterial infection, is a highly prevalent disease in dairy cattle characterized by physical, chemical and usually bacteriological changes in milk and by pathological changes in the glandular tissues (LEBLANC et al, 2006). Drug residues in milk have a potential health hazard effects for the consumer and may cause allergic reactions, interference in the intestinal flora and the rapid emergence of resistant bacteria (SAINI et al, 2012). For these reasons, this problem continues to deserve the attention of researchers and general population
