Probiotics have been widely used in gastroenteritis due to acute and chronic illnesses. However, evidence supporting the effectiveness of probiotics in different health conditions is inconclusive and conflicting. The aim of this study was to review the existing literature on the effects of probiotics on gastroenteritis among adults. Only original articles on clinical trials that demonstrated the effects of probiotics in adults with gastroenteritis were used for this analysis. Multiple databases, such as PubMed, Google Scholar, MEDLINE and Scopus databases, were searched for the data. The study followed standard procedures for data extraction using a PRISMA flow chart. A quality appraisal of the selected studies was conducted using CADIMA. Finally, a meta-analysis was performed. Thirty-five articles met the selection criteria; of them, probiotics were found effective in the treatment and/or prevention of chronic inflammatory bowel disease (IBD), including ulcerative colitis and Crohn's disease in 17 (49%), and the treatment of in 4 (11.4%), antibiotic-induced diarrhea in 3 (8.6%), infection in 2 (5.7%) and diverticulitis in 1 (2.9%), while the remaining 7 (20%) were ineffective, and 1 study's results were inconclusive. The meta-analysis did not demonstrate any significant protective effects of probiotics. Having a τ value of zero and I of 6%, the studies were homogeneous and had minimum variances. Further studies are suggested to evaluate the beneficial effects of probiotics in IBDs and other chronic bowel diseases.

Swine influenza virus invades the host through the respiratory mucosa, which severely restricts the development of the pig breeding industry. To construct monomeric and trimeric vaccines, we developed recombinant Escherichia coli Nissle 1917 (EcN) strains that express the receptor binding site (RBS) of the hemagglutinin (HA) antigen from H1N1 swine influenza virus. After the mucosal immunization of mice, we found that probiotics activated CD40 and CD86 in DCs and increased the levels of IL-4 and IFN-γ secretion by T cells.

As the number of infections and deaths attributable to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection continues to rise, it is now becoming apparent that the health impacts of the Coronavirus disease (COVID-19) may not be limited to infection and the subsequent resolution of symptoms. Reports have shown that patients with SARS-CoV-2 infection may experience multiple symptoms across different organ systems that are associated with adverse health outcomes and develop new cardiac, renal, respiratory, musculoskeletal, and nervous conditions, a condition known as Long COVID or the post-acute sequelae of COVID-19 (PASC). This review provides insights into distinct subphenotypes of Long COVID and identifies microbiota dysbiosis as a common theme and crucial target for future therapies.
