  The present investigation was designed to assess the role of temperature, an important environmental parameter on the chemotaxis Vibrio cholerae 0139 towards homogenates of Anabaena sp., amino acids (L-serine and L-alanine) and a carbohydrate (D-glucose). A series of temperature (4, 25, 37 and 44 ° C) was assessed in a capillary tube technique to observe its effect on the chemotaxis of V. cholerae 0139 at six different incubation periods of 15, 30, 45, 60, 75 and 90 min. The highest effect was observed at 25 ° C irrespective of the agents tested followed by 37 and 44 ° C. However, no significant chemotactic movement was recorded at 4 ° C. Among the various types of attractants used, maximum response was observed with L-serine as compared to L-alanine and D-glucose and Anabaena sp. homogenates.

  Bacterial chemotaxis is one of the important mechanisms of association of bacteria and other living biota. To investigate the role of chemotaxis that might function for association of Vibrio cholerae -0139 with different aquatic flora and fauna, the homogenates of four aquatic plants and animals namely water hyacinth (Eichhornia crassipes), water cress (Pistia stratiotes), oyster (Lamellidens marginalis) and snail (Pila globosa) were examined in chemotaxis capillary assay. Chemotaxis assay revealed that V. cholerae -0139 swims towards the homogenates of aquatic plants and animals with a higher chemotactic response being observed for 4% solution of P. globosa homogenate. The influence of temperature and salinity on the chemotaxis of V. cholerae -0139 revealed that at 250C and 1.7% salinity favoured the chemotactic motility towards the homogenates of aquatic flora and fauna. Vibrio cholerae -01 also showed the chemotactic response to the homogenates of snail muscles.
