Exactly 10 years ago,on 25 October 2012,a group of scientists,policy-makers,and practitioners undertook an ambitious project to launch a new open-access journal,named Infectious Diseases of Poverty[1].The idea had originated from a think-tank put forth by the Special Programme for Research and Training in Tropical Diseases(TDR),an organisation co-sponsored by the United Nations Children’s Fund(UNICEF),the United Nations Development Programme(UNDP),the World Bank,and the World Health Organization(WHO).Indeed,this think-tank published a comprehensive Global Report for Research on Infectious Diseases of Poverty[2]that guided the scope and remit of Infectious Diseases of Poverty.

This study investigated the use of a product based on yacon (PBY) in microbiological, physical-chemical and intestinal characteristics of Wistar rats artificially constipated with Loperamide®. Thirty-two rats were divided into four groups: Control (C), Constipated Control (CC), PBY (not constipated) and Constipated PBY (PBYC). The dosage of 0.14 g of FOS+ inulin/kg was tested. Microbiota, pH and faeces characteristics of faeces and caecal contents were evaluated. Caecal weight, morphometry of caecal villi and the concentration of short-chain fatty acids were determined. Higher caecal weight was identified in the PBYC animals as well as higher width, height and depth of cripts. The PBY group showed the highest (p < 0.05) concentration of butyrate (93.2 ± 65.5 mmol/L). The supplementation with PBY positively altered the intestine epithelial tissue in constipated animals, keeping the integrity of the caecum crypts.
