LTA and digestive system infectious disorder: Once again, this may reflect our relatively small cohort size when stratified by nutritional status; however, stunting in the children in this study may in part reflect the sequelae of environmental (tropical) enteropathy26,27 resulting from frequent and recurrent intestinal infections, including by CT-expressing V. cholerae and immunologically related heat labile toxin (LT)–expressing enterotoxigenic Escherichia coli (ETEC), and therefore possibly may reflect previous exposure and immunological priming to CT/LT in these children.
