|Title:||Influence of abiotic environmental factors on the abundance and distribution of <i style="">Vibrio</i> species in coastal waters of Kerala, India|
|Abstract:||Quantification of <i style="">Vibrio</i> spp. and abiotic environmental factors on the proliferation and longevity of <i style="">V.</i> <i style="">parahaemolyticus</i> and <i style="">V. cholerae </i>was studied. Water samples were collected onboard <i style="">CRV</i> Sagar Purvi from Veli, Neendakara, Kochi, Calicut and Kasaragod along the Kerala coast for hydrological and microbiological parameters. Pearson correlation and regression analysis were done for evaluating the relationship between abiotic environmental factors and abundance of <i style="">Vibrio</i> spp. Hydrological and microbiological variations are greatly observed at nearshore transect of all stations. Significant correlation was observed between <i style="">V. cholerae</i> and nutrients and negative correlation with pH, dissolved oxygen and salinity. The population of <i style="">V.</i> <i style="">parahaemolyticus</i> showed an inverse correlation with dissolved oxygen. pH, salinity and nutrients and these factors were responsible for the incidence and abundance of <i style="">Vibrio cholerae </i>and <i style="">Vibrio parahaemolyticus</i>. The proliferation and survivality of <i style="">V.parahaemolyticus</i> in marine waters is independent to hydrological variables while that<i style=""> </i>of <i style="">V.cholerae</i> is determined by certain abiotic factors.|
