BACKGROUND OF THE INVENTION This invention relates broadly to a class of oral vaccines for the prevention of enteric disease. A living, non-pathogenic mutant, oral vaccine strain of Salmonella typhi has already been shown to be safe and effective in protecting against typhoid fever; it is a mutant,

BACKGROUND OF THE INVENTION TF (typhoid fever) in man is the clinical manifestation of a generalized or systemic infection by Salmonella typhi, a gram-negative bacterium which penetrates the organism through the gastrointestinal tract, usually by ingestion of water or food contaminated by human

The present invention relates in particular to a stabilized bivalent hepatitis A/typhoid fever (HA-Vi) immunization composition in which the Vi valence conserves its immunogenic power for at least 24 months approximately. Hepatitis A and typhoid fever are two diseases for which a vaccine already

BACKGROUND OF THE INVENTION Salmonella enterica serovar Typhi (S. typhi) and paratyphi (S. paratyphi), the causes of typhoid fever, results in more than 200,000 annual deaths (Parry et al., N. Engl. J. Med. 347:1770-1782; Crump et al., 2008, Antimicrob. Agents Chemother. 52:1278-1284; Raffatellu et

FIELD OF INVENTION This invention relates to obtaining a biochemical vaccine against Salmonella fevers, typhoid and paratyphoid fevers. BACKGROUND The threat of an epidemic of Salmonella fevers is constant in the world as shown by epidemiological reports and the seriousness of the spread of

FIELD OF THE INVENTION The present invention relates to attenuated Salmonella mutants which constitutively express the Vi antigen, as well as vaccines against typhoid fever containing the same, live vector vaccines containing the same, and DNA-mediated vaccines containing the same. BACKGROUND OF THE

INTRODUCTION This invention relates to a process for the production of a non-toxic B subunit of the heat-labile enterotoxin (LT-B) from a human isolate of an enterotoxigenic strain of Escherichia coli. This process utilizes recombinant DNA techniques, in which the requisite gene sequence is inserted

TECHNICAL FIELD The present invention relates to an oral vaccine useful for preventing and treating a bacterial infectious disease, and a method for producing the same. BACKGROUND ART Typhoid fever is one of the infectious diseases caused by Salmonella enterica var. Typhi, which is a type of
