Salmonella typhi and Typhoid Fever — NEET Biology
✅ Asked in NEET 2024Salmonella typhi is a pathogenic bacterium which causes typhoid fever in human beings. These pathogens generally enter the small intestine through food and water contaminated with them and migrate to other organs through blood. Sustained high fever (39° to 40°C), weakness, stomach pain, constipation, headache and loss of appetite are some of the common symptoms of this disease. Intestinal perforation and death may occur in severe cases. Typhoid fever could be confirmed by
NTA tests students on identifying Salmonella typhi as the causative agent of typhoid fever and understanding its transmission route through contaminated food and water. Students often confuse typhoid with other bacterial infections or forget that confirmation requires blood culture/Widal test, not just clinical symptoms. Remember: Salmonella typhi enters via the small intestine, causes sustained high fever (39-40°C), and spreads hematogenously to other organs. The key trap is that students may know the symptoms but forget the bacterium's identity or the diagnostic method—NEET repeatedly tests this combination across multiple years.
