Chapter 32.10, Problem 1CR
Summary Introduction
Salmonellosis is a type of gastrointestinal disease which is caused by pathogenic bacterium Salmonella. Species of Salmonella usually inhabit intestine of warm-blooded animals and are commonly found in sewage waste. Salmonella enterica is the most pathogenic species which is responsible for causing salmonellosis.
