Stained Salmonella O and H Suspensions are standardized, smooth suspensions of killed bacteria which have been stained to facilitate reading of agglutination tests. To carry out a successful infection process, this bacterium needs to survive alkaline and acid pH conditions presented in the mouth, stomach, small intestine, and gallbladder. Most people in the United States get typhoid as a result of visiting another country where the food or water supply has been contaminated. enterica serovar Typhi is a serovar of the O:9 (D1) serogroup. Multidrug-resistant strains of S. Typhi are rapidly spreading. Recently, Salmonella typhi strains have shown resistance against antibacterial drugs such as fluoroquinolones, chloramphenicol, ampicillin, azithromycin and co-trimoxazole, as declared in the Geneva convention 2017 (Summary of the October 2017), that are clinically used to treat Salmonella infections (Khan and Musharraf 2004). Abstract. Typhoid fever, also known as typhoid, is a disease caused by Salmonella serotype Typhi bacteria. Salmonella typhi is a pathogen that causes the human disease of typhoid fever. Salmonella typhimurium is a pathogenic Gram-negative bacteria predominately found in the intestinal lumen. Approximately 21 million cases are estimated, resulting in 216,519 deaths in the year 2000 ().The bacterium generally causes an acute febrile illness known as enteric fever, and a chronic carrier state may contribute to adenocarcinoma of the gallbladder ().
