RESUMO
Hemolytic-uremic syndrome (HUS) is a serious disease in children, attributable in the majority of cases to infection with Shiga toxin (Stx)-producing Escherichia coli. Using gnotobiotic piglets orally infected with E. coli O157:H7, which develop Stx-related cerebellar lesions and fatal neurological symptoms, we show that administration of Stx2-specific antiserum well after challenge protected, in a dose-response fashion, against these symptoms for at least 24 h after bacterial challenge. Twenty-six of 30 piglets given Stx2 antiserum survived the challenge, compared to only 4 of 16 animals given control serum or saline. Given our observations in piglets, Stx antibody of human origin may likewise prevent HUS in children.
