  1. Transcutaneous immunization with Clostridium difficile toxoid A induces systemic and mucosal immune responses and toxin A-neutralizing antibodies in mice.
  2. Enterotoxigenic Escherichia coli secretes a highly conserved mucin-degrading metalloprotease to effectively engage intestinal epithelial cells.
  3. Comparative proteomic analysis of the PhoP regulon in Salmonella enterica serovar Typhi versus Typhimurium.
  4. EatA, an immunogenic protective antigen of enterotoxigenic Escherichia coli, degrades intestinal mucin.
  5. Zinc influences innate immune responses in children with enterotoxigenic Escherichia coli-induced diarrhea.
  6. Natural selection in a bangladeshi population from the cholera-endemic ganges river delta.
  7. In vivo expression of Salmonella enterica serotype Typhi genes in the blood of patients with typhoid fever in Bangladesh.
