“…Bacteroidetes and Firmicutes were detected, which are the bacteria that make up the majority of human and animal gut microbiota. 30,31) Acidobacteria, Nitrospirae, and Verrucomicrobia were also detected in all the wells. After the sewerage works (see above), the pH became alkaline in well N1 (samples N1 0922, N1 1015, and N1 1221).…”

Private wells are used daily worldwide as convenient household water sources. In Japan, where water supply coverage is high, well water is occasionally used for non-potable purposes, such as irrigation and watering. Currently, the main microbiological test of well water is designed to detect Escherichia coli, which is an indicator of fecal contamination, using culture methods. Water use such as watering generates bioaerosols, which may cause airborne infection. However, many causative bacteria of aerosol-derived infections, such as Legionella spp., are difficult to detect using culture methods. Thus, more comprehensive modern assessment is desirable for securing the microbiological quality of well water. Here, the bacterial community structure of five private wells located in different environments was examined using the rapid and portable MinION sequencer, which enabled us to identify bacteria to the species level based on full-length 16S ribosomal RNA (rRNA) gene sequences. The results revealed the differences in the bacterial community structures of water samples from the five wells and detected Legionella pneumophila and Aeromonas hydrophila as new candidate microbial indicators. The comprehensive analysis method used in this study successfully detected bacteria causing opportunistic infections, which are difficult to detect by conventional methods. This approach is expected to be routinely applied in the future as a highly accurate method for assessing the microbiological quality of private well water.

“…The previous investigation by Evivie et al [ 40 ] confirmed the medicinal usage of L. delbrueckii isolates as a probiotic against foodborne pathogens. Moreover, recent studies have evidenced the role of E. faecium as a promising probiotic candidate for both human and animal use [ 41 , 42 , 43 , 44 ]. Despite 16S rRNA being a very conserved region, six of our isolates revealed huge divergence in that region and this could be explained by the effect of environmental, demographic, genetic factors, and the maternal lifestyle on modifying the microbial diversity of human milk and infants’ gut [ 45 ].…”

Human milk comprises a diverse array of microbial communities with health-promoting effects, including colonization and development of the infant’s gut. In this study, we characterized the bacterial communities in the Egyptian mother–infant pairs during the first year of life under normal breastfeeding conditions. Out of one hundred isolates, forty-one were chosen for their potential probiotic properties. The selected isolates were profiled in terms of morphological and biochemical properties. The taxonomic evidence of these isolates was investigated based on 16S rRNA gene sequence and phylogenetic trees between the isolates’ sequence and the nearest sequences in the database. The taxonomic and biochemical evidence displayed that the isolates were encompassed in three genera: Lactobacillus, Enterococcus, and Lactococcus. The Lactobacillus was the most common genus in human milk and feces samples with a high incidence of its different species (Lacticaseibacillus paracasei, Lactobacillus delbrueckii, Lactiplantibacillus plantarum, Lactobacillus gasseri, and Lacticaseibacillus casei). Interestingly, BlastN and Jalview alignment results evidenced a low identity ratio of six isolates (less than 95%) with database sequences. This divergence was supported by the unique physiological, biochemical, and probiotic features of these isolates. The isolate L. delbrueckii, ASO 100 exhibited the lowest identity ratio with brilliant probiotic and antibacterial features suggesting the high probability of being a new species. Nine isolates were chosen and subjected to probiotic tests and ultrastructural analysis; these isolates exhibited antibiotic resistance and antibacterial activity with high probiotic characteristics, and high potentiality to be used as prophylactic and therapeutic agents in controlling intestinal pathogens.

Natural herbs and functional foods contain bioactive molecules capable of augmenting the immune system and mediating anti-viral functions. Functional foods, such as prebiotics, probiotics, and dietary fibers, have been shown to have positive effects on gut microbiota diversity and immune function. The use of functional foods has been linked with en-hanced immunity, regeneration, improved cognitive function, maintenance of gut mi-crobiota, and significant improvement in overall health. The gut microbiota plays a critical role in maintaining overall health and immune function, and disruptions to its balance have been linked to various health problems. SARS-CoV-2 infection has been shown to affect gut microbiota diversity, and the emergence of variants poses new challenges to combat the virus. SARS-CoV-2 recognizes and infects human cells through ACE2 receptors prevalent in lung and gut epithelial cells. Humans are prone to SARS-CoV-2 infection because the respiratory and gastrointestinal tracts are rich in microbial diversity and contain high ACE2 and TMPRSS2. This review article explores the potential use of functional foods in mitigating the impact of SARS-CoV-2 variants on gut microbiota diversity and the potential use of functional foods as a strategy to combat these effects.
