Various enteric microorganisms

“Various enteric microorganisms” represents the complex ecosystem of microorganisms inhabiting the gastrointestinal tract. The four dominant bacterial phyla are Firmicutes (Bacillota), Bacteroidetes (Bacteroidota), Actinobacteria (Actinomycetota), and Proteobacteria (Pseudomonadota)[1][4]. Major genera include Bacteroides (constituting about 30% of gut bacteria[4]), Clostridium, Faecalibacterium, Eubacterium, Ruminococcus, Bifidobacterium, Escherichia, and Lactobacillus[1][4]. The family Enterobacteriaceae specifically includes over 30 genera and more than 100 species of Gram-negative bacteria[2], containing both harmless symbionts and pathogens like Salmonella, E. coli, Klebsiella, and Shigella[2]. The microbiota composition varies across different regions of the digestive tract and between individuals, remaining relatively stable within an individual over time but influenced by age, diet, lifestyle, and medication use[1][4].
