Epidemiology, Clinical Presentation, Laboratory Diagnosis.
Salmonella Typhimurium is an intracellular bacterium that replicates with macrophages, specialised cells designed to 'clean' the blood of pathogenic organisms. The intracellular location means that many antibiotics are ineffective, and vaccines dependent on T lymphocytes, which are important to host immunity to reinfection. We are currently examining how the bacterium can persist inside cells.
Shin-Ichi Aizawa, in The Flagellar World, 2014. Salmonella enterica serovar Typhimurium (S. Typhimurium) is a Gram-negative rod-shaped bacterium.S. enterica serovar Typhi is the most frequent foodborne pathogen, while serovar Typhimurium is not harmful to humans but is to the mouse, as the name indicates, and thus is widely used as a lab strain. The flagellum of S. typhimurium is the best.
Typhoid fever vaccines Introduction. Typhoid fever is caused by a Gram-negative bacterium, Salmonella typhi. A similar but often less severe disease is caused by Salmonella serotype paratyphi A. The clinical spectrum of typhoid fever can vary from mild illness with low-grade fever, malaise and dry cough to severe abdominal discomfort with multiple complications that can become fatal. Two.

Typhoid fever, also known simply as typhoid, is a bacterial infection due to a specific type of Salmonella that causes symptoms. Symptoms may vary from mild to severe, and usually begin 6 to 30 days after exposure. Often there is a gradual onset of a high fever over several days. This is commonly accompanied by weakness, abdominal pain, constipation, headaches, and mild vomiting.
Introduction. The gram-negative bacterial genus Salmonella is divided in two species, Salmonella enterica and Salmonella bongori.Only the Salmonella enterica subspecies enterica is of clinical relevance for humans and is further classified into more than 2,600 serovars. The human restricted serovar Typhi (STY) and the closely related serovar Paratyphi A (SPTA) cause enteric fever (), while the.
Salmonella Typhi (S. Typhi) are bacteria that infect the intestinal tract and the blood. The disease is referred to as typhoid fever. S. Paratyphi bacteria cause a similar, but milder illness, which comes under the same title. Paratyphoid has a shorter duration, generally, than typhoid. S. Typhi and S. Paratyphi are common in many developing.
