DISEASE CAUSING MICROBES 

Water body contaminated with sewage or waste water is most likely to possess pathogenic microbes fatal to humans when consumed and these microbes may be bacteria, virus or protozoa. E. coli, Salmonella, Pseudomonas, Campylobacter and Shigella (are some of the bacterial pathogens in water), Enterovirus, Noravirus, rota virus (are some of the viral pathogens), Entamoeba, Giardia lamblia are examples of possible parasitic pathogens in the water.

There are many water borne pathogenic diseases identified like amoebiasis, giardiasis, cryptosporidiosis, SARS, hepatitis A, botulism, cholera, dysentery, E.coli infection, typhoid etc. posing potential health risk and many analytical methods has been derived to detect the presence of such pathogens in the drinking water.

Here are several ways to prevent water-borne diseases:

  • Drink only filtered/boiled water.
  • Store water in a clean container,
  • Water jars/containers should be washed daily.
  • Consume warm and home cooked foods while avoiding street foods.
