What is the specific agent for Typhoid Fever?

The specific agent for Typhoid Fever is the Typhoid bacillus, known scientifically as Salmonella typhi. This bacterium is responsible for causing Typhoid Fever, a systemic infection that spreads through contaminated food and water. Understanding that Salmonella typhi is the causative agent is essential because it highlights the importance of sanitation and hygiene practices in preventing the spread of this illness.

The other bacteria listed do not cause Typhoid Fever. Campylobacter jejuni is typically associated with gastrointestinal infections, Listeria monocytogenes causes listeriosis, and Vibrio cholerae is the cause of cholera. Each of these pathogens has distinct transmission routes and disease mechanisms, further emphasizing the specificity of Salmonella typhi as the only agent responsible for Typhoid Fever.
