The Role of Probiotics, Beneficial Microorganisms, In the Treatment and Resistance Against Pathogenic Bacteria.

Abstract

The aim of this research paper is to identify the capability of microorganisms in eliminating antibiotic-resistant bacteria and to find a newer, safer, and more cost-effective technique for treating pathogenic and harmful bacteria to human and animal health. It also seeks to explore new, modern, and effective methods for treating chronic diseases that have harmful side effects on human health and are environmentally polluting, and which result from pathogenic organisms that have high resistance to conventional antibiotics. Furthermore, it aims to produce an effective and safe alternative from beneficial probiotics like Lactobacillus and lactic acid bacteria. To date, several studies have reported an alarming increase in pathogen resistance to current antibiotic therapies and treatments. Therefore, the search for effective alternatives to counter their spread and the onset of infections is becoming increasingly important. In this regard, microorganisms of the former Lactobacillus genus have demonstrated the ability to reduce the virulence of pathogens. lactobacilli have been used as an effective therapy for treatment of several pathological conditions displaying an overall positive safety profile. This review summarises the supporting therapeutic efficacy of lactobacilli. In addition to the production of bioactive substances, self- and coaggregation, and substrate competition, lactic acid bacteria is useful for human healthy such as Applications of lactobacilli include kidney support for renal insufficiency, pancreas health, management of metabolic imbalance, and cancer treatment and prevention. In vitro and in vivo investigations have shown that prolonged lactobacilli administration induces qualitative and quantitative modifications in the human gastrointestinal microbial ecosystem with encouraging perspectives in counteracting pathology-associated physiological and immunological changes. It also highlights the important and vital role in treating diarrhea and some digestive system disorders by using probiotic bacteria, such as lactic acid bacteria found in yogurt, kefir, and some dairy products, which play a significant role in treating and combating harmful and pathogenic bacteria present in the stomach. Thus, with the continuous use of beneficial bacteria, the number of beneficial probiotic bacteria increases, which attack pathogenic bacteria and causes gastrointestinal diseases.
