What are the most common bacterial pathogens found in wastewater?
The most common bacterial pathogens found in untreated wastewater are Salmonella and Shigella. Other bacterial microorganisms include Vibrio, Clostridium, Yersinia, Campylobacter, and Leptospira. Escherichia coli (E.coli), which can cause gastroenteritis, is generally not considered a pathogen because it is a microorganism that naturally inhabits the gastrointestinal tract of man.
