Engineered living materials (ELMs) made of bacteria in hydrogels have shown considerable promise for therapeutic applications through controlled and sustained release of complex biopharmaceuticals at low costs and with reduced wastage. While most therapeutic ELMs use E. coli due to its large genetic toolbox, most live biotherapeutic bacteria in development are lactic acid bacteria due to native health benefits they offer.

Background: Numerous studies have confirmed a close relationship between the pathogenicity of influenza and respiratory microbiota, but the mechanistic basis for this is poorly defined. Also, the majority of these studies have been conducted on murine models, and it remains unclear how far these findings can be extrapolated from murine models to other animals. Considering that influenza A virus is increasingly recognized as an important canine respiratory pathogen, this study investigated the cross-talk between nasal and lung tissues mediated by microbes and its association with influenza susceptibility in a beagle dog model.

The aim of this study was to assess the gamma-aminobutyric acid (GABA) production in plant-based fermented beverages with kefir cultures (milk and water kefir). Water-soluble extracts of peanut and Brazil nut were evaluated as non-dairy substrates for the development of new bioactive beverages. A total of 12 formulations were developed and evaluated for their chemical composition, physical chemical characterization, and microbiological counts (aerobic mesophilic bacteria, lactobacilli, lactococci and yeasts).

Several studies have suggested that probiotics could play a role in the management of patients with chronic bacterial prostatitis (CBP). In this randomized, placebo-controlled clinical study, we evaluated the efficacy and safety of consumption of probiotics containing human DG as an add-on treatment in patients with clinical recurrences of CBP, through gut microbiota modification analysis. Enrolled patients with CBP were randomized to receive for 3 months probiotics containing human DG or placebo following 1 month treatment with ciprofloxacin.

It is known that probiotics have direct and indirect effects on many systems in the body, especially the gastrointestinal system. Interest in using probiotic strain-derived cell components and metabolites has also increased as a result of the significant benefits of probiotics. Although many terminologies and definitions are used for these components and metabolites, the International Scientific Association of Probiotics and Prebiotics (ISAPP) recommended the use of the term postbiotic in 2021, which is defined as "a preparation of inanimate microorganisms and/or their components that confers a health benefit on the host".
