Bovine mastitis is the most serious dairy problem in terms of economic losses to the dairy industry. In Algeria, dominates as one of the most prevalent diseases in dairy cattle among the dairy farms. Mastitis treatment with antibiotics leads to the development of antibiotic resistant strains and consumer health problem. Multidrug-resistant bacteria have become a major health issue. With new generations of virulence and resistant bacteria, we need to improve our understanding and produce novel techniques to control these pathogenic strains. In our study, the activity of several extracts from seven medicinal plants, namely Mentha pulegium, Lavandula dentate, Origanium sp, Marrubium vulgare, Salvia bicolor, Blackstonia perfoliata, and Phlomis crinita, traditionally used in Algeria was investigated against 26 methicillin resistant staphylococci and multi-resistant Escherichia coli. (E.coli) isolated from animals with mastitis manifestation by the disc diffusion method.
Results revealed the potential of extracts of Salvia bicolor, Marrubium vulgare and Phlomis crinita as antibacterial agents against strains isolated from bovine mastitis and support the possible use of these phytotherapic agents in the clinical management of the disease. Further studies into their toxicity and phytochemistry are advocated.
