Question: Who manufactured the combination of inactivated an infectious disease of the liver  and Vi polysaccharide of Salmonella typhi bacteria?

Context paragraphs:
Hepatitis A: Hepatitis A is an infectious disease of the liver caused by the hepatitis A virus (HAV).  Many cases have few or no symptoms, especially in the young.  The time between infection and symptoms, in those who develop them, is between two and six weeks.  When symptoms occur, they typically last eight weeks and may include nausea, vomiting, diarrhea, jaundice, fever, and abdominal pain.  Around 10–15% of people experience a recurrence of symptoms during the six months after the initial infection.  Acute liver failure may rarely occur, with this being more common in the elderly.

Germ theory denialism: Germ theory denialism is the belief that germs do not cause infectious disease, and that the germ theory of disease is wrong.  It usually involves arguing that Louis Pasteur's model of infectious disease was wrong, and that Antoine Béchamp's was right.  One of the first movements to deny the germ theory was the Sanitary Movement, which was nevertheless central in developing America's public health infrastructure.  One well-known advocate of this form of denialism is Bill Maher, who has claimed that Pasteur recanted germ theory on his deathbed.  Shikha Dalmia, writing in "The Washington Examiner", referred to Maher as a "germ theory denier" after he made these comments on "Real Time with Bill Maher" on March 4, 2007.  However, in response to criticism of his views, Maher said, on the October 16, 2009 episode of his show, that he accepted microorganisms as the cause of some disease, but expressed skepticism about other topics in medicine, such as vaccination.  Similarly, the following month, Maher wrote that he "understand[s] germ theory," but that he still thought that "Western medicine ignores too much [sic] the fact that the terrain in which bacteria can thrive is crucial and often controllable, which shouldn't even be controversial."  Harriet Hall published an article in "Skeptic" where she describes her experience arguing with germ theory denialists.

Rose spots: Rose spots are red macules 2-4 millimeters in diameter occurring in patients suffering from enteric fever (which includes typhoid and paratyphoid).  These fevers occur following infection by "Salmonella typhi" and "Salmonella paratyphi" respectively.  Rose spots may also occur following invasive non-typhoid salmonellosis.

Infectious disease (medical specialty): Infectious disease, also known as infectious diseases, infectious medicine, infectious disease medicine or infectiology, is a medical specialty dealing with the diagnosis, control and treatment of infections.  An infectious disease (ID) specialist's practice may consist largely of managing nosocomial (hospital-acquired) infections, or it may be out-patient based.

Hepatyrix: Hepatyrix is a combined Hepatitis A and Typhoid vaccination.  A combination of inactivated Hepatitis A virus and Vi polysaccharide of Salmonella typhi bacteria manufactured by GlaxoSmithKline

Kauffman–White classification: The Kauffmann–White classification or Kauffman and White classification scheme is a system that classifies the genus "Salmonella" into serotypes, based on surface antigens.  It is named after Philip Bruce White and Fritz Kauffmann.  First the "O" antigen type is determined based on oligosaccharides associated with lipopolysaccharide.  Then the "H" antigen is determined based on flagellar proteins (H is short for the German "Hauch" meaning "breath" or "mist"; O stands for German "ohne" meaning "without").  Since "Salmonella" typically exhibit phase variation between two motile phenotypes, different "H" antigens may be expressed.  Salmonella that can express only one "H" antigen phase consequently have motile and non-motile phenotypes and are termed monophasic, whilst isolates that lack any "H" antigen expression are termed non-motile.  Pathogenic strains of "Salmonella" Typhi, "Salmonella" Paratyphi C, and "Salmonella" Dublin carry the capsular "Vi" antigen (Vi for virulence), which is a special subtype of the capsule's K antigen (from the German word "Kapsel" meaning capsule).

Endo agar: Endo agar (also called Endo's medium) is a microbiological growth medium with a faint pink colour.  Originally developed for the isolation of "Salmonella typhi", it is now used mostly as a coliform medium.  Most gram-negative organisms grow well in this medium, while growth of gram-positive organisms is inhibited.  Coliform organisms ferment the lactose in this medium, producing a green metallic sheen (i.e. "Escherichia coli"), whereas non-lactose-fermenting organisms produce clear, colourless colonies, i.e. "Salmonella" sp. .

Center for Infectious Disease Research: Center for Infectious Disease Research, formerly known as Seattle BioMed, Seattle Biomedical Research Institute or SBRI, is the largest independent, non-profit organization in the United States focused solely on infectious disease discovery research.  The mission of Seattle BioMed's 250+ employees is to eliminate the world's most devastating infectious diseases through leadership in scientific discovery.  Seattle BioMed is headquartered and has research labs in the South Lake Union area of Seattle, WA.  Seattle BioMed's research focuses on four areas of infectious disease: HIV/AIDS, malaria, tuberculosis (TB), and Emerging & Neglected Diseases (END) like African sleeping sickness, leishmaniasis, Chagas disease, and toxoplasmosis.  Seattle BioMed is engaged in early stages of the scientific pipeline including bench science and malaria clinical trials and has expertise in immunology, vaccinology, and drug discovery.

Widal test: The Widal test, developed in 1896 and named after its inventor, Georges-Fernand Widal, is a presumptive serological test for enteric fever or undulant fever whereby bacteria causing typhoid and malaria fever are mixed with a serum containing specific antibodies obtained from an infected individual.  In cases of "Salmonella" infection, it is a demonstration of the presence of O-soma false-positive result.  Test results need to be interpreted carefully to account for any history of enteric fever, typhoid vaccination, and the general level of antibodies in the populations in endemic areas of the world.  Typhidot is the other test used to ascertain the diagnosis of typhoid fever.  As with all serological tests, the rise in antibody levels needed to perform the diagnosis takes 7–14 days, which limits its applicability in early diagnosis.  Other means of diagnosing "Salmonella typhi" (and "paratyphi") include cultures of blood, urine and faeces.  These organisms produce HS from thiosulfate and can be identified easily on differential media such as bismuth sulfite agar.

Hepatitis C: Hepatitis C is an infectious disease caused by the hepatitis C virus (HCV) that primarily affects the liver.  During the initial infection people often have mild or no symptoms.  Occasionally a fever, dark urine, abdominal pain, and yellow tinged skin occurs.  The virus persists in the liver in about 75% to 85% of those initially infected.  Early on chronic infection typically has no symptoms.  Over many years however, it often leads to liver disease and occasionally cirrhosis.  In some cases, those with cirrhosis will develop complications such as liver failure, liver cancer, or dilated blood vessels in the esophagus and stomach.
