Abstract:
Many recent studies were focusing on heavy metal pollution but a little attention on
bacteria contamination. Since the freshwater fishes were taken in human diet, it is very
important to know the diversity of the bacteria associated with the fishes either it is
pathogenic or not. This study was conducted to investigate the microbial diversity from
freshwater fishes from polluted environment. In this study, seven species of freshwater
fishes were examined included Ompok siluroides, Clarias meladerma, Labiobarbus
leptocheilus, Osteocheilus hesselti, Oxygaster anomalura, Rasbora natura and Rasbora
bankanensis. The fishes were collected in August 2007 from Paya Sungai Udang, a
swamp that believed polluted with leachate from groundwater since it is situated next to a
landfill. The identification of the bacteria was done by using macro, micromorphology
and biochemical tests.
