Unlike other Salmonella bacteria, S. Typhi is not found in animals. Typhoid fever is extremely rare in the United States and is almost always related to travel to an area of the world where typhoid fever is common, such as Asia, Africa, and Latin America.Application of Salmonella typhi s outer membrane (OMP)in diagnosis of Typhoid Article (PDF Available) in International Journal of Current Research · August 2013 with 447 Reads Cite this publication.

Background/Aims—The serodiagnosis of infection with Salmonella typhi,using the Widal agglutination assay, relies on patients antibodies to the O=9,12 lipopolysaccharide (LPS) antigens, H=d flagellar antigens, and the Vi capsular antigens. A Vi agglutination titre of 1/40 has traditionally.Salmonella typhi is the human pathogen that causes thyphoid fever. O an H are the types of antigen of those bacteria. This has flagellar antigen H antigen and Lipopolysaccharides antigen is somatic or O antigen.

It is a Gram - and very mobile. Measuring 2-3 microns in length. In addition to possessing somatic antigens (Ag O) and flagellar (H Ag), used for serological identification, Salmonella typhi was also a capsular antigen (Ag V). By typing with bacteriophages, Salmonella typhi can be divided into more than 80 varieties stable and well defined.Determination of baseline antibody titre to S. typhi/paratyphi in Ile-Ife, Nigeria. study is to determine the baseline antibody titres to Salmonella typhi/paratyphi in 265 (95.0%) had reciprocal antibody titre of < or = 80 to H. antigen of S. typhi.

Detection of antibodies to Salmonella "O" antigens in typhoid fever by Muñóz O, Hernández-Velarde R, Garduño-Rodríguez G, González-Arroyo S, Gutiérrez .Non-typhoidal Salmonella serovars (NTS) cause a very different disease compared to typhoidal Salmonella serovars such as S. typhi and S. paratyphi. In humans, where NTS cause local gastroenteritis and diarrhea, these bacteria do not breach the epithelial barriers and are cleared by the mucosal immune system.

Jan 9, 2013 S. Paratyphi A is less common than S. Typhi, responsible for approximately agglutinating antibodies against the O and H antigens of S. Typhi.Salmonella typhi Ty2 has one large chromosome that is 4.7 Mb and unlike CT18, it does not have plasmids and can be affected by antibiotics. In fact, the current vaccine was developed using S. typhi Ty2. Out of the 204 pseudogenes in Salmonella, 195 genes are the same in both strains CT18 and Ty2, making them 98% identical (1,5).
