Abstract

Some plants have been reported to be of medicinal values and reserve some antimicrobial properties. One of such plants is Mitracarpus scaber and its effect on bacterial growth is evaluated. The study aimed at evaluating the phytochemical analyses and antimicrobial potentials of Mitracarpus scaber against aquatic bacteria. Leaves of Mitracarpus scaber and phytochemical analysis and antimicrobial investigation of ethanolic and aqueous extracts of the leaves were carried out against bacteria isolated from diseased Catfish from various farms. The phytoconstituents detected include saponins, tannins, flavonoids, tarpenoids, steroids, anthraquinones and alkaloids in both aqueous and ethanolic extracts. The ethanolic extract had zones of inhibition similar to that of standard antibiotics (enrofloxacin) across all tested microbes. The lowest minimum inhibitory concentration of ethanolic extract of M. scaber was against Bacillus sp with 10mg/ml while the highest was 85mg/ml against Staphylococcus species. The results of the assays showed promising evidences that M. scaber is a potential antibacterial agent against aquatic microbes. However, further studies are recommended to fractionate its constituents and determine the in vitro and in vivo anti-microbial activities and the exact mechanism of action of the constituents.
