Pathogenic microorganism in gastrointestinal tract

Pathogenic microorganisms in the gastrointestinal tract collectively denote the diverse array of bacteria, viruses, fungi, archaea, and protozoa capable of causing disease in the digestive system. These agents can invade and colonize the gut, disrupt normal function, modulate the immune response, and produce toxins that contribute to varied GI symptoms and diseases, such as inflammation, infections, and sometimes cancer. Therapeutic approaches targeting these microbes focus on eliminating or reducing their populations (antibiotics, antifungals, antiparasitics, phage therapy), restoring microbial balance (probiotics, FMT), or selectively eradicating pathogenic strains while preserving beneficial ones. However, the term itself is not a specific molecular target but an umbrella category for a vast group of organisms and thus is not suitable as a canonical target for molecular drug development[1][2][5][6][7][8].
