Title of Collaborative Activity:

Probiotic and Prebiotic Working Group [PPWG]

Description of Collaborative Activity:

The Probiotic and Prebiotic Working Group (PPWG) is a trans-National Institutes of Health (NIH) effort formed in 2006 to identify gaps and challenges in prebiotic and probiotic research. Their goals include (1) facilitating interactions and collaborations among research scientists in the field of probiotics and prebiotics, (2) advancing prebiotic and probiotic research, and (3) understanding the role of gut microbiota and use of prebiotics and probiotics in health and disease. The working group strives to promote constructive interactions across NIH Institutes, Centers, and Offices, by disseminating real-time information and keeping PPWG members abreast of current and future activities occurring in the fields of probiotics and prebiotics. The group meets quarterly to form allied partnerships and collaborate on various pre- and probiotic activities.Two trans-NIH Program Announcements were released in 2015 and were renewed in 2018 (PA-18-902; PA-18-876 ).
