Polyclonal sera from typhoid patients and a monoclonal antibody, mAb ATVi, which recognizes the capsular polysaccharide Vi antigen (ViCPS), were used to select for peptides that mimic the ViCPS by using a phage-displayed random 12-mer peptide library. Two major common mimotopes selected from the
BACKGROUND
Typhoid fever remains an important cause of morbidity and mortality in the developing countries. Vi capsular polysaccharide conjugate vaccine demonstrated safety and efficacy in young children in high endemic regions. A novel typhoid conjugate vaccine based on plant polysaccharide pectin
It was shown that in continuous cultivation of typhoid bacilli, by changing the rate of dilution and the regimens of carbohydrate and oxygen supply it was possible to determine conditions under which the most highly immunogenic vaccines were obtained and the maximal synthesis of antigens was
1. In a patient with typhoid fever, who had taken, during eleven days, 132 grammes of lactate of calcium by the mouth, as well as 5 grammes of chloride of calcium subcutaneously, there developed, eleven days after the subcutaneous infusion, a large abscess of the breast from which Bacillus typhosus
Salmonella enterica serovar Typhi (S. Typhi) differs from most other salmonellae in that it causes a life-threatening systemic infection known as typhoid fever. The molecular bases for its unique clinical presentation are unknown. Here we find that the systemic administration of typhoid toxin, a
The detection of antigen in the urine is increasingly being used for diagnosis of parasitic infections. A urinary antigen has recently been demonstrated in visceral leishmaniasis (VL), using a latex agglutination test. The results of our study show that the detected antigen is: heat-stable,
BACKGROUND
Enterocutaneous fistula (ECF) in children poses a lot of management challenges due to sepsis, malnutrition, fluid and electrolyte deficits, which are frequent complications. Knowledge of prognostic factors of postoperative ECF is essential for therapeutic decision-making processes. This
In a stock culture of the hog-cholera bacillus, which was passed through a series of rabbits 14 years ago, an organism was found that differs from the original culture in that it fails to form gas from the carbohydrates that are usually attacked by this organism, while acid formation persists. This
Salmonella enterica serovar Gallinarum (Salmonella Gallinarum) is the causative agent of fowl typhoid (FT), a severe systemic disease of chickens that results in high mortality. Since 1992, FT has become one of the most serious bacterial diseases in poultry in Korea. The purpose of this study was to
