ABSTRACT
Globally, the gastroenteritis or diarrhoea has become a more significant problem today due to infection causedby water-or foodborne pathogen Vibrio cholera. In this concern, an investigation was carried out to evaluatethe vibriocidal potential of the different solvent extracts of leaf and rhizome of Maranta arundinacea under invitro condition. For this, aqueous, methanolic, ethanolic, and hexane extracts of both leaf and rhizome of M.arundinacea were tested against the pre-isolated strains of V. cholerae, such as SPAB1, SPAB4, and SPAB5by agar well diffusion and minimum inhibitory concentration (MIC) method. All the solvent extracts of bothleaf and rhizome were found to be active against the tried strains of V. cholera; however, ethanolic extractshowed maximum inhibitory effect against SPAB1 strain with an inhibition zone of 26.23 ± 0.53 mm (MIC of80.00 ± 10.06 µg/ml) and 24.27 ± 0.12 mm (MIC of 100.00 ± 12.82 µg/ ml) in rhizome and leaf samples, respectively.Then, the effectiveness was followed in SPAB4 and SPAB5; however, it was not much more significant to that ofSPAB1. Therefore, it was suggested that the rhizome and leaf extracts which proved to be potentially effective canbe used as the natural alternative for the treatment of diarrhoea caused by Vibrio infection
