The aquatic flora and fauna as reservoirs of Vibrio cholerae: a review.

reduce the particulate load, the viability of the organism Aquatic animals and plants may be reservoirs of may be related to the presence of particulates. They y cholerae in the environment. We first consider the suggested that V. cholerae prefer an epibiotic form of possibilities of aquatic fauna as possible reservoirs, habitat. As the organisms can be recovered from filtered Various kinds of aquatic fauna including oysters, estuarine and sea water as well as particulate-free water, zooplankton, crabs, etc. have been considered as potential they also suggested that V. cholerae can survive as a habitats of V. cholerae in the aquatic environment from planktonic form for a certain period of life. time to time. Dastidar and Narayanaswami (13) studied Lee et al. (10) in a 3-year survey from 1979 to 1981 the chitinase activity of 7 strains of V. cholerae classical of the incidence of V. cholerae in water, animals and biotype, 15 strains of El Tor biotype and 4 NAG (non birds in Kent, England, observed that about 6% of all the agglutinating) vibrios. Detectable amounts of chitinase gulls sampled contained V. cholerae non-01. They also activity were observed in most of the strains studied, collected the water samples from the same ditches where Nalin (14) suggested that V. cholerae can survive during y6 h / WCre CaU could not isolate any the interepidemic period attached to copepods in the
