Article Abstract
Probiotics and live bacterial therapeutics are garnering increased attention for use in human health and have the potential to revolutionise the treatment of gastrointestinal diseases. However, a pervasive feature of bacteria that must be considered in the design of safe and effective probiotics and live bacterial therapeutics is their capacity for rapid evolution, both at the individual (epi)genetic level and in terms of population dynamics. Here we summarise gastrointestinal-specific evolution of bacteria, focussing on genetic and population levels of adaptation to factors such as carbon source availability, environmental stressors, and interactions with the native microbiome. We also address regulatory and safety considerations for the development of probiotics and live biotherapeutics from an evolutionary perspective, with a discussion of methods that utilise evolution to improve probiotic safety and efficacy via directed evolution, in comparison to another popular approach, genetic engineering.

The symbiosis between intestinal bacteria and the human body's physiological processes can modulate health. The intestinal microbiota is linked to the development of neurotrophic factors; therefore, it is increasingly related to the modulation of nervous system pathologies. Moreover, microbiota can interfere with inflammation and oxidative stress, which are closely linked to cardiovascular risk factors and several other inflammatory conditions, such as kidney and neurodegenerative diseases.

While probiotics are widely recognized for their adjunctive benefits in ulcerative colitis treatment, the therapeutic potential of heat-killed cells remains underexplored. This study directly compared the efficacy of Bifidobacterium breve B2798 probiotics (LB group) and their heat-killed counterparts (DB group) in alleviating dextran sulfate sodium (DSS)-induced colitis in rats. Over a 21-day intervention, both treatments significantly mitigated colitis symptoms, including weight loss, colon damage, and splenomegaly, with heat-killed cells demonstrating superior histological improvement over live probiotics.

Inflammatory bowel disease (IBD) is a term that describes disorders involving long-standing inflammation of tissues in the digestive tract. The onset and exacerbation of IBD is linked to multiple factors, including genetic and immunological influences, diet, and gut bacteria. Additionally, it is associated with a high risk of cancer.

Microbial exopolysaccharides (EPS) are emerging as critical effector molecules orchestrating host immunity. Their remarkable structural diversity, driven by variations in monosaccharide composition, charge, and glycosidic linkages, dictates potent immunomodulatory functions through specific interactions with host pattern recognition receptors (CLRs, TLRs), triggering defined cellular responses and cytokine profiles, often with minimal toxicity. Beyond direct immune effects, EPS shape the gut environment by fortifying barrier integrity and acting as prebiotics.

(brine shrimp) is a vital live feed in aquaculture, providing essential nutrients during the early developmental stages of aquatic species. This study aimed to evaluate the efficacy of synbiotic-enriched as a live feed for hybrid catfish larvae ( × ), using locally isolated probiotics ( and ) and the commercial prebiotic inulin. The study was conducted in two phases.
