Aflatoxins: Occurrence, exposure, and binding to lactobacillus species from the gut microbiota of rural ugandan children

Probiotic Enrichment and Reduction of Aflatoxins in a Traditional African Maize-Based Fermented Food

Fermentation of food products can be used for the delivery of probiotic bacteria and means of food detoxification, provided that probiotics are able to grow, and toxins are reduced in raw materials with minimal effects on consumer acceptability. This study evaluated probiotic enrichment and detoxification of kwete, a commonly consumed...

Feasibility of a novel on-site detection method for aflatoxin in maize flour from markets and selected households in Kampala, Uganda

In sub-Saharan Africa, there is a high demand for affordable and accessible methods for on-site detection of aflatoxins for appropriate food safety management. In this study, we validated an electrochemical immunosensor device by the on-site detection of 60 maize flour samples from six markets and 72 samples from households in Kampala. The...

The probiotic Lactobacillus rhamnosus for alleviation of helicobacter pylori-associated gastric pathology in East Africa

The probiotic Lactobacillus rhamnosus GG (LGG) can play a role in establishing a harmless relationship with Helicobacter pylori and reduce gastric pathology in East African populations. H. pylori has the ability to inhabit the surface of the mucous layer of the human stomach and duodenum. In the developing world, an estimated 51% of the...

Lactobacillus rhamnosus probiotic food as a tool for empowerment across the value chain in Africa

Perhaps by serendipity, but Lactobacillus rhamnosus has emerged from the 1980s as the most researched probiotic species. The many attributes of the two main probiotic strains of the species, L. rhamnosus GG and GR-1, have made them suitable for applications to developing countries in Africa and beyond. Their use with a Streptococcus thermophilus...

Naturally fermented milk from northern Senegal: Bacterial community composition and probiotic enrichment with lactobacillus rhamnosus

A variety of foods fermented with lactic acid bacteria serve as dietary staples in many African communities; yet, their bacterial profiles are poorly characterized. The integration of health-promoting probiotics into naturally fermented milk products could make a profound impact on human health. Here, we characterize the bacterial community...

Locally sourced probiotics, the next opportunity for developing countries?

We describe factors promoting the exploration of locally sourced probiotics, targeting local populations to balance human needs and market opportunities. This would be particularly beneficial for people in developing countries, who generally lack access to affordable probiotics and are often exposed to poor hygiene conditions, toxic compounds,...

A novel consortium of Lactobacillus rhamnosus and Streptococcus thermophilus for increased access to functional fermented foods

Background: The lactic acid bacterium Lactobacillus rhamnosus GG is the most studied probiotic bacterium with proven health benefits upon oral intake, including the alleviation of diarrhea. The mission of the Yoba for Life foundation is to provide impoverished communities in Africa increased access to Lactobacillus rhamnosus GG under the name...

Development of a locally sustainable functional food based on mutandabota, a traditional food in southern Africa

A probiotic dairy product was developed on the basis of a traditional dish called mutandabota to enable resource-poor populations in southern Africa to benefit from a functional food. Mutandabota is widely consumed in rural southern Africa, making it an ideal food matrix to carry probiotics. First, a process to produce probiotic mutandabota was...

Harnessing microbiome and probiotic research in sub-Saharan Africa: recommendations from an African workshop

To augment capacity-building for microbiome and probiotic research in Africa, a workshop was held in Nairobi, Kenya, at which researchers discussed human, animal, insect, and agricultural microbiome and probiotics/prebiotics topics. Five recommendations were made to promote future basic and translational research that benefits Africans.

Genome instability in Lactobacillus rhamnosus GG

We describe here a comparative genome analysis of three dairy product isolates of Lactobacillus rhamnosus GG (LGG) and the ATCC 53103 reference strain to the published genome sequence of L. rhamnosus GG. The analysis showed that in two of three isolates, major DNA segments were missing from the genomic islands LGGISL1,2. The deleted DNA segments...
