Pathogenic bacterial species in the gut

Pathogenic bacterial species in the gut refer to bacteria capable of causing disease within the gastrointestinal tract. Unlike beneficial or commensal microbes, these pathogens may produce toxins, promote inflammation, disrupt normal gut function, and interact adversely with the host immune system. Common examples include toxin-producing strains of Clostridioides difficile, Salmonella enterica, pathogenic Escherichia coli, Staphylococcus aureus, and certain Fusobacterium species. Their presence and overgrowth are linked to infections, inflammatory bowel disease, colorectal cancer, and systemic illnesses. Treatment strategies target these organisms using antibiotics, bacteriophage therapy, probiotics, and restoration of normal microbiota composition. Due to the broad and diverse nature of this group, "Pathogenic bacterial species in the gut" does not represent a discrete drug target but is an umbrella term for multiple disease-associated bacterial populations[1][3][5][6][7].
