As well, humans can become ill by eating contaminated fish. There are many types of animals that graze on bacteria and fungi. The bacterium is present in the intestinal tract in huge numbers, and is more numerous than the disease-causing bacteria and viruses. Testing for microbes that cause disease (i.e., Salmonella typhymurium and Vibrio cholerae) can be expensive and, if the bacteria are present in low numbers, they may escape detection. However, the date of retrieval is often important. Algae, protozoa and other phytoplankton play key role in the food chain in water and certain or-ganisms perform photosynthesis. .
