Pathogens or germs are microorganisms that produce diseases. Common pathogens regulated in drinking water include bacteria (such as Salmonella) and protozoan parasites (such as Giardia and Cryptosporidium). Other pathogens (such as enteric [intestinal] viruses) are controlled in drinking water and associated with turbidity. Note that water sources are commonly tested for the possible presence of pathogens by measuring total coliform bacteria.
Any microorganism that can cause disease. Salmonella is always considered a pathogenic microorganism. E. coli is considered an opportunistic pathogen. It is not always pathogenic, but given the opportunity, it can cause food-borne illness.
Any organism that can cause disease. Many bacteria are pathogens but some are not e.g. Staphylococcus aureus is a pathogen and causes wound infections;Lactobacillus acidophilus is not a pathogen, indeed it is of benefit in maintaining the health acidity of the vagina.
