| Abstract: | Quantification of Vibrio spp. and abiotic environmental factors on the proliferation
and longevity of V. parahaemolyticus and V. cholerae was studied. Water samples
were collected onboard CRV 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 Vibrio spp. Hydrological and microbiological variations are greatly
observed at nearshore transect of all stations. Significant correlation was
observed between V. cholerae and
nutrients and negative correlation with pH, dissolved oxygen and salinity. The
population of V. parahaemolyticus showed an inverse correlation with dissolved
oxygen. pH, salinity and nutrients
and these factors were responsible for the incidence and abundance of Vibrio cholerae and Vibrio parahaemolyticus.
The proliferation and survivality of V.parahaemolyticus
in marine waters is independent to hydrological variables while that of V.cholerae
is determined by certain abiotic factors. |
