Altman, EleonoraGabastou, Jean-MarcFernández, HeribertoVérez, Vicente2007-11-132006-09-152007-11-132006http://hdl.handle.net/10625/25933Preliminary research suggests that H. pylon Lipopolysaccharide (LPS) phenotype falls within the previously reported Lewis xly classification with 3 % of strains being non-typeable. Interestingly, Lewis b occurs in over 20 % of strains tested. This is significant since North American H. pylon isolates lack Lewis a and Lewis b antigens and so far, these antigens were only reported in Asian isolates. The report describes a multidisciplinary research program aimed at identification of the optimal common LPS structure/s that can be utilized in the design of protective LPS-based conjugate vaccine in Latin America and Caribbean countries.Text21 p. : ill.enIMMUNIZATIONVACCINATIONDISEASE CONTROLSTRATEGIC PLANNINGCAPACITY BUILDINGLATIN AMERICAMETHODOLOGYSTATISTICAL ANALYSISPARTICIPATORY RESEARCHCHILESOUTH AMERICACUBACANADAGLOBAL HEALTHHELICOBACTER PYLORIIDRC Final Report
