Active Ingredients: Azithromycin
All three of these candidates have been evaluated in phase 1 studies and have demonstrated promising safety and immunogenicity profiles.
Although less advanced in clinical development, vaccines are also being developed against shigellosis, including Shigella sonnei strain WRSS 1, consisting of a live, oral candidate vaccine attenuated by a deletion in the virG plasmid virulence gene, which has shown good immunogenicity in phase 1 trials in both the United States and Israel 102, 125.
Parenteral conjugate vaccines of purified S.
Several new attenuated Salmonella enterica serovar Typhi strains are under development for use as live oral vaccines; three of these are currently at an advanced stage of clinical testing.
A third live, oral attenuated, single-dose typhoid vaccine consists of the M 01 ZH 09 strain, carrying the targeted mutation of a structural protein SsaV of Salmonella pathogenicity island-2, a virulence factor that allows Salmonella species to inject bacterial effector components into host cells, allowing them to escape being killed by oxidative burst.
M 01 ZH 09 has shown acceptable safety and excellent immunogenicity in preliminary human trials 99, although results from field trials are pending.
Finally, the currently licensed polysaccharide Vi vaccine has been conjugated to a nontoxic recombinant P.
A randomized, controlled trial of 2 doses of the conjugate vaccine given to 12,000 Vietnamese children of 2 to 5 years of age resulted in 91. A prototype oral whole-cell killed C.
In addition to vaccines, another area of research includes an effort to better assess the value of personal hygiene precautions in preventing traveler's diarrhea, in order to guide travelers in their choice of food and drink while abroad 144.
Besides further research, improvements in the public health infrastructure in tropical and developing countries will likely lead to benefits not only to local populations but also to visitors 14.
Hotels and restaurants can also play a role in reducing the risk of their guests' developing traveler's diarrhea by instituting educational programs that improve the culinary hygiene of their workers, which has been shown to reduce the incidence of traveler's diarrhea in Jamaica 6.
