Susceptibility responses of cat fish – Clarias gariepinus to infection with Pseudomonas aeruginosa visà-vis treatment with chloramphenicol were investigated in the present study. Thirty healthy and physically active fishes weighing between 200-350g sourced from Challawa Gorge Dam, Karaye, Kano State were used for the study. These were divided into three aquarium tanks A, B, C (ten in each case). Fishes in A were infected with 1.0ml (about 1.2 x 106 cfu/ml) of Pseudomonas aeruginosa pyrenterally through linea alba by ventral medial furrow.

Drinking water sources are epidemiologically suspected as one of the major transmission agents for pathogenic and perhaps drug resistant Enterobacteria. Accordingly, in the period October, 1995 – September, 1996, water samples as were available from tap, borehole, well, dams and rivers in randomly selected 19 Local Government areas of Kano State were screened for these bacteria. 1201 isolates comprising Citrobacter sp. (16.91%); Enterobacter aerogenes (14.99%); Klebsiella sp. (10.24%); Proteus sp. (9.58%); Shigella sp. (9.49%); Escherichia coli (8.24%); Salmonellae (7.99%) and Vibrio sp.
