Explain what is meant by an enteric pathogen as opposed to enteric bacilli.

An enteric pathogen is any non-native organism that invades the gastrointestinal system and causes disease. This is very different from enteric bacilli, which normally reside in the human GI tract and do not cause disease under normal circumstance. Though enteric bacilli may causes disease outside of the GI tract (such as the urinary tract or blood stream), they are native to the human GI tract and often beneficial. Enteric pathogens are usually spread by contamination of food or by people who carry them on the skin or elsewhere. They are common nosocomial pathogens (spread in healthcare settings). Enteric pathogens are transmitted often by the "fecal-oral" route.

Explain why anaerobic organisms are generally not the enteric pathogens seen in a routine fecal specimen. Why are these anaerobic organisms not seen in a routine fecal culture?

A routine culture involves plating specimen on several different kinds of enriched media. Each is designed to allow a ...

Enterobacteriaceae

The family Enterobacteriaceae contains some organisms living in the intestines without harming the host and some organisms that are harmful to the host.

Based on your research, respond to the following:

What is meant by the term "enteric pathogen"?
Why are anaerobic organisms generally not seen in a routine fecal specimen or culture?
What are the indole test, methyl red test, voges-proskauer test and citrate test (IMViC) reactions? Describe in detail all four reactions (what media is used, important ingredients, what each reaction measures, and what positive and negative results mean).
Create a flowchart for the isolation and identification of specific enteric bacteria from fecal samples.
