    Abstract Next-generation probiotics (NGPs) represent an innovative group of beneficial bacteria that are currently undergoing research and development. NGPs are designed not only for conventional use as foods or dietary supplements but are also tailored for pharmaceutical applications. Research indicates that NGPs show therapeutic promise in addressing various chronic ailments. Offering multiple advantages over conventional probiotics, NGPs present opportunities for personalized probiotic therapies, involvement in synthetic biology and gene editing, participation in combination therapies, targeted delivery methods, and application in therapeutic settings. Our review discusses the potential therapeutic effect of the NGPs, covering diverse research trajectories for NGPs, including their identification, characterization, and targeted delivery. Furthermore, this review elucidates the influence of NGPs on critical aspects of human health, specifically, gut health, immune function, and broader health outcomes. Mechanistic insights encompass the production of bioactive compounds, competitive interactions with pathogenic bacteria, the modulation of immune cell activity, and the reinforcement of the gut barrier. What is noteworthy is that the current review points out the prevalent NGP strains and their diverse sources, providing a highlight for the comprehensive framework for understanding their potential applications and their future benefits in the domain of advanced therapeutics.

    Abstract Objectives: Antimicrobial-resistant bacteria of the order Enterobacterales are emerging threats to global public and animal health, leading to morbidity and mortality. The emergence of antimicrobial-resistant, livestock-associated pathogens is a great public health concern. The genera Enterobacter and Lelliottia are ubiquitous, facultatively anaerobic, motile, non-spore-forming, rod-shaped Gram-negative bacteria belonging to the Enterobacteriaceae family and include pathogens of public health importance. Here, we report the first draft genome sequences of a rare Lelliottia nimipressuralis strain MEZLN61 and two Enterobacter kobei strains MEZEK193 and MEZEK194 in Africa.
    Methods: The bacteria were isolated from environmental wastewater samples. Bacteria were cultured on nutrient agar, and the pure cultures were subjected to whole-genome sequencing. Genomic DNA was sequenced using an Illumina MiSeq platform. Generated reads were trimmed and subjected to de novo assembly. The assembled contigs were analysed for virulence genes, antimicrobial resistance genes, and extra-chromosomal plasmids, and multilocus sequence typing was performed. To compare the sequenced strains with other, previously sequenced E. kobei and L. nimipressuralis strains, available raw read sequences were downloaded, and all sequence files were treated identically to generate core genome bootstrapped maximum likelihood phylogenetic trees.
    Results: Whole-genome sequencing analyses identified strain MEZLN61 as L. nimipressuralis and strains MEZEK193 and MEZEK194 as E. kobei. MEZEK193 and MEZEK194 carried genes encoding resistance to fosfomycin (fosA), beta-lactam antibiotics (bla
    Conclusion: The genome sequences of strains L. nimipressuralis MEZLN6, E. kobei MEZEK193, and E. kobei MEZEK194 will serve as a reference point for molecular epidemiological studies of L. nimipressuralis and E. kobei in Africa. In addition, this study provides an in-depth analysis of the genomic structure and offers important information that helps clarify the pathogenesis and antimicrobial resistance of L. nimipressuralis and E. kobei. The detection of mcr-9, which is associated with very low-level colistin resistance in Enterobacter species, is alarming and may indicate the undetected dissemination of mcr genes in bacteria of the order Enterobacterales. Continuous monitoring and surveillance of the prevalence of mcr genes and their associated phenotypic changes in clinically important pathogens and environmentally associated bacteria is necessary to control and prevent the spread of colistin resistance.
