Abstract
Subclinical mastitis is a form of mastitis that does not exhibit any obvious signs on the animal itself. However, it impacts greatly on the economical lost in the dairy industry. To make matters worse, antimicrobial resistance has become a serious threat and herbal alternatives are greatly sought after. In this project, the leaf extracts of Melastoma malabathricum (Senduduk), Ardisia crispa (Mata Ayam) and Tetracera indica (Mempelas) were tested against bacterial isolates Staphylococcus aureus, Staphylococcus hyicus and Staphylococcus intermediate obtained from milk samples from a total of 14 subclinical mastitis positive cows in Taman Pertanian Universiti, UPM. The Kirby-Bauer method or disc diffusion method shows that all plant extract possess antimicrobial activity with M. malabathricum (inihibtion zone= 22.045± 0.828mm) as the most potent extract against all three strains of Staphyloccocus spp. followed by A. crispa (inhibition zone= 13.303± 0.828mm) and T. inidica (inhibition zone= 9.727± 0.828mm). Minimum inhibitory concentration and minimum bactericidal concentration was also recorded in this study; however, the values were found to be not significant. In conclusion, all the extracts exhibit antimicrobial properties against the common bacterial isolates of subclinical mastitis.
