Nontyphoidal salmonellae are phagocytosed along the distal ileum and colon The fact that there are no virulence genes shared by typhoidal Salmonella serovars that are absent from non-typhoidal Salmonella serovars, suggests that this innate immune evasion is mediated by different mechanisms in different typhoidal serovars. This review discusses what is known about the clinical pathogenesis of typhoid fever Typhoid fever - is a life-threatening illness caused by the bacterium Salmonella typhi. Acute Gastroenteritis (AGE)- Gastroenteritis (also known as gastro, gastric flu, tummy bug in some countries, and stomach flu, although unrelated to influenza) is inflammation of the gastrointestinal tract, involving both the stomach and the small intestine (see also gastritis and enteritis) and resulting in acute diarrhea
CLINICAL MANIFESTATION (Onset): * Headache * Chilly sensation * Aching all over the body * Nausea, vomiting & diarrhea * Fever is higher in the morning than it was in the afternoon * Breathing is accelerated * Furred tongue * Skin is dry & hot * Abdomen is distended & tender * Rose spots appear on the abdominal wall on 7th & 9th day * On the second week symptoms become more aggravate Pathophysiology of Typhoid Fever.

Typhoid fever is a systemic infection caused by the bacterium Salmonella enterica subspecies enterica serotype Typhi (S. Typhi). The disease causes much morbidity and mortality in developing counties and is characterized by prolonged fever, bacterial growth in cells of the reticuloendothelial system, and significant inflammation of the lymphoid organs of the small intestine The pathogenesis of enteric fever depends on a number of factors including the infecting species and infectious dose. Ingested organisms survive exposure to gastric acid before gaining access to the small bowel, where they penetrate the epithelium, enter the lymphoid tissue, and disseminate via the lymphatic or hematogenous route
