Bacterial profile of the gut of Puntius parrah exposed to sodium dodecyl sulphate


Author(s): S.Umamaheswari, Rini Raphael, M.Murali

Abstract: The influx of synthetic chemicals into the waterways by anthropogenic activity could modulate the gut bacterial flora of fishes. The present study was conceived with an aim to analyse the changes that could occur in the intestinal bacteria of Puntius parrah on exposure to SDS. It was observed that SDS at 3 mg/L significantly elevated the THB population in the fore gut and hindgut of Puntius parrah. Proteus sp. was predominant in the fore gut and hind gut of Puntius parrah exposed to low concentrations of SDS (1 mg/L and 3 mg/L). Pseudomonas sp. was detected in the gut of Puntius parrah exposed to low concentrations of SDS (1 mg/ L) and SDS unexposed ones. Providencia sp., and Paenibacillus sp.,were present in the foregut and hind gut, respectively in the SDS exposed (5 mg/L) Puntius parrah when compared to the control. These observation indicate that SDS could have   altered the gut bacterial population in Puntius parrah.
