Abstract

The bacterial load, Pseudomonas aeruginosa and their artificial infection to Oreochromis niloticus were studied in water of four swamps in the Rajshahi University campus during November, 2001 to October, 2002. The load of P. aeruginosa was found to vary from 6.80×105 to 5.08×106 ml-1. In artificial infection to Oreochromis niloticus, the mortality rates was recorded at 90, 50, 30, 20 and 0% at 1.92 × 108, 1.92×107, 1.92×106 1.92×105 and 1.92×104 CFU fish ml-1, respectively. The average bacterial load in the swamps (1.92×106CFU ml-1) was slightly higher than that prevailed in the control pond (1.90×106CFU ml-1). Swamps can be utilized at the present bacterial load for the fish culture. Key words: Swamp, pathogenicity, Pseudomonas, Oreochromis niloticus. J. bio-sci. 14: 77-81, 2006
