Probiotics are strains of selected microorganisms that provide a health benefit to the host. Probiotics must meet certain functional, technological, and safety requirements to be considered a probiotic. Through this study, we learned about the various probiotic microorganisms that are found in nature, as well as their traits, mode of action, and advantageous effects upon human health and the diseases as they are seen as major threats to food safety. The need for environmentally friendly agriculture and aquaculture is driving an increase in research on probiotics. Live microbial feed additives, or probiotics, have been shown to enhance the health of both people and other animals. This review's primary goals are to outline current developments in the field of gut microbiota research and demonstrate the crucial role those intestinal bacteria play in the emergence of many medical diseases. Lastly, probiotics hold enormous promise as a different and eco-friendly strategy and seem to be an effective way to manage microbial infections in various contexts. Studies on their actions and potential mechanisms of action against several pathogenic bacteria are highlighted in this review. As the probiotics industry develops further, this review study is a useful tool for scientists, medical professionals, and health enthusiasts looking for a more nuanced understanding of the potential and difficulties of using bacteria for human health and more.
