Bovine mastitis continues to be the most costly disease to the dairy farmers. In Tamil Nadu 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. The present study is an in vitro antibacterial activity of two medicinal plants against bovine udder isolated bacterial pathogens. Aqueous and methanol extracts of two plants were investigated by agar disc and well-diffusion method. Methanol extracts of Tridax procumbens and Spathodea campanulata showed significant activity against coagulase positive Staphylococcus aureus (8.0 ± 0.70) and Streptococcus agalactiae (7.6 ± 0.54) respectively. Phytochemical screening of the plants revealed the presence of alkaloids, tannin, saponin, steroids, terpenoids and falvonoids.
