Use of a patch containing heat-labile toxin from Escherichia coli against travellers' diarrhoea: a phase II, randomised, double-blind, placebo-controlled field trialSarah A Frech
IOMAI Corporation, Gaithersburg, MD, USA
Lancet 371:2019-25. 2008..We investigated the rate of diarrhoea attacks, safety, and feasibility of a vaccine containing heat-labile enterotoxin (LT) from ETEC delivered to the skin by patch in travellers to Mexico and Guatemala...
Safety and immunogenicity of an oral, inactivated, whole-cell vaccine for Shigella sonnei: preclinical studies and a Phase I trialR McKenzie

Vaccine 24:3735-45. 2006..We conclude that SsWC was immunogenic and protective in animal studies and well tolerated and immunogenic in a Phase I trial...
A double-blind, placebo-controlled trial to evaluate the efficacy of PTL-003, an attenuated enterotoxigenic E. coli (ETEC) vaccine strain, in protecting against challenge with virulent ETECRobin McKenzie
Division of Infectious Diseases, Johns Hopkins University, Johns Hopkins Bayview Medical Center, 4940 Eastern Avenue, Baltimore, MD 21224, United States
Vaccine 26:4731-9. 2008..Higher serum anti-CS3 IgA titers at the time of challenge correlated with less severe diarrheal illness...
Safety and immunogenicity of WRSd1, a live attenuated Shigella dysenteriae type 1 vaccine candidateRobin McKenzie
Center for Immunization Research, Johns Hopkins Bloomberg School of Public Health, Baltimore, MD 21205, USA
Vaccine 26:3291-6. 2008..Days of fecal shedding of the vaccine strain, but not dose ingested, correlated with stronger immune responses. These results suggest that to be effective an attenuated Shigella vaccine must colonize well...
Transcutaneous immunization with the heat-labile toxin (LT) of enterotoxigenic Escherichia coli (ETEC): protective efficacy in a double-blind, placebo-controlled challenge studyRobin McKenzie
Division of Infectious Diseases, Johns Hopkins University, Johns Hopkins Bayview Medical Center, 4940 Eastern Ave, Baltimore, MD 21224, United States
Vaccine 25:3684-91. 2007..An enterotoxigenic Escherichia coli (ETEC) vaccine could reduce diarrhea among children in developing countries and travelers to these countries. The heat-labile toxin (LT) of ETEC is immunogenic but too toxic for oral or nasal vaccines...
Comparative safety and immunogenicity of two attenuated enterotoxigenic Escherichia coli vaccine strains in healthy adultsRobin McKenzie
Center for Immunization Research, Department of International Health, Johns Hopkins University, Bloomberg School of Public Health, 624 N Broadway, HH, Rm 203, Baltimore, MD 21205, USA
Infect Immun 74:994-1000. 2006..Based on its superior immunogenicity, which was comparable to that of a virulent ETEC strain and other ETEC vaccine candidates, PTL-003 will be developed further as a component of a live, oral attenuated ETEC vaccine...
Comparative evaluation of the antibody in lymphocyte supernatant (ALS) and enzyme-linked immunospot (ELISPOT) assays for measuring mucosal immune responses to Shigella antigensAndrea J Feller
Department of International Health, Johns Hopkins Bloomberg School of Public Health, Baltimore, MD, USA
Vaccine 29:8487-9. 2011..Based on these observations, the ALS assay is a practical and flexible alternative to ELISPOT for measuring mucosal IgA responses to Shigella LPS antigen...
Systemic pharmacokinetics of rifaximin in volunteers with shigellosisDavid N Taylor
Center for Immunization Research, Department of International Health, The Johns Hopkins Bloomberg School of Public Health, Baltimore, Maryland, USA
Antimicrob Agents Chemother 52:1179-81. 2008..Peak plasma rifaximin concentrations were low after nine consecutive doses, and no accumulation was observed. Rifaximin serum levels were minimal and similar to those previously reported in studies of healthy volunteers...
Rifaximin, a nonabsorbed oral antibiotic, prevents shigellosis after experimental challengeDavid N Taylor
Center for Immunization Research, Department of International Health, Johns Hopkins Bloomberg School of Public Health, Baltimore, MD, USA
Clin Infect Dis 42:1283-8. 2006..This double-blind, placebo-controlled study was conducted to assess the efficacy of the nonabsorbed oral antibiotic rifaximin to prevent shigellosis in volunteers challenged with Shigella flexneri...
Volunteer challenge with enterotoxigenic Escherichia coli that express intestinal colonization factor fimbriae CS17 and CS19Robin McKenzie
Department of Medicine, Johns Hopkins University, Johns Hopkins Bayview Medical Center, MD, USA
J Infect Dis 204:60-4. 2011..These studies establish the relative pathogenicity of ETEC expressing newer class 5 fimbriae and suggest suitability of the LT|CS17-ETEC challenge model for interventional trials...

Lactoferrin for the prevention of post-antibiotic diarrhoeaAlison M Laffan
Department of Epidemiology, Johns Hopkins University, Baltimore, MD 21224, USA
J Health Popul Nutr 29:547-51. 2011..Fewer patients in the lactoferrin group experienced diarrhoea compared to controls (p = 0.023). Based on the findings, it is concluded that human lactoferrin may reduce post-antibiotic diarrhoea...
Evaluation of Salmonella enterica serovar Typhi (Ty2 aroC-ssaV-) M01ZH09, with a defined mutation in the Salmonella pathogenicity island 2, as a live, oral typhoid vaccine in human volunteersB D Kirkpatrick
