A new study titled ‘Assessment of Water Quality
and Sediment to Understand Special Properties of River Ganga,’ has noted that Ganga
River water significantly higher proportion of organisms with antibacterial
properties. The study was commissioned by the Union Water Resources Ministry.
Under the study, five pathogenic species of bacteria
viz. Escherichia, Enterobacter, Salmonella, Shigella, Vibrio were selected and
isolated from the Ganga, Yamuna and the Narmada. Their numbers were then compared
with the bacteriophages present in the river water. bacteriophages are a kind of
virus that kill bacteria and are frequently found in proximity to bacteria.
The study has found that River Ganga particularly
in its upper Himalayan stretches has more bacteriophages than other rivers. Samples
drawn from the Ganga contained almost 1,100 kinds of bacteriophage.
