Age-Specific Prevalence of Serum Antibodies to the Invasion Plasmid and Lipopolysaccharide Antigens of Shigella Species in Chilean and North American Populations
1 Jul 1992
Abstract excerpt
Shigella species have virulence plasmids that encode outer membrane proteins (invasion plasmid antigens, Ipa) associated with pathogenicity. Western blots were used to detect antibodies to Ipa in sera from 390 Chilean children, and these responses were compared with those of a US population of infants and adults. Antibodies to lipopolysaccharide (LPS) of Plesiomonas shigelloides and Shigella flexneri 2a were...
