Antibacterial Activity of Tanacetum vulgare L. Extracts against Clinical Isolates of Bovine Mastitis

A bovine mastitis is an infectious disease, which usually treated with antibiotics. Alternatively, herbal medicine has been proposed due to bacterial resistance. The aim of this study was determine the antibacterial activity acetonic and ethanolic extracts dried flowers leaves Tanacetum vulgare L. against mastitis-inducing clinical isolates such as Escherichia coli, Streptococcus agalactiae, uberis, Serratia liquefaciens, Staphylococcus aureus, reference cultures S. aureus E. coli. T. showed partial tested strains aureus. MIC MBC values a 70% ethanol extract (MIC = 3.4 mg/mL, 3.4–6.8 mg/mL) were lower than for 15.7–31.4 62.9–125.9 mg/mL). flower low coli 53.9 53.9–107.8 agalactiae (MIC, leaf had minimal effects 31.4–62.9 53.9–125.9 liquefaciens 125.9 However, higher phenolic content that did not correlate effects. could be combined obtain broader
