Human norovirus and Clostridium difficile represent two leading causes of acute gastroenteritis worldwide with significant morbidity and mortality. Despite great efforts in the development of vaccines against both infections, to date there is still no vaccine available on the market. NIAID, NIH awarded a five year R01 to the collaborative team of Dr. Lijuan Yuan at Virginia Tech, Dr. Hangping Feng at University of Maryland at Baltimore, and Dr. Viviana Parreño at INTA, Argentina, to develop a novel prophylaxis using genetically engineered probiotic Saccharomyces boulardii to secrete “Sb-aNoVCd”, multi-specific single-domain VHH antibodies against both noroviruses and Clostridium difficile toxins. The encapsulated Sb-aNoVCd will be used orally for the prevention and treatment of human norovirus and Clostridium difficile gastroenteritis.
