Gastrointestinal Infections and Immunity

Gastrointestinal infections, caused by viruses, bacteria, and parasites, are leading causes of global morbidity and mortality, particularly in children and immunocompromised individuals. Common pathogens include norovirus, rotavirus, Helicobacter pylori, Salmonella, and Giardia. These infections can lead to acute gastroenteritis, chronic inflammation, ulcers, and even cancer.

The body’s immune system plays a vital role in fighting gastrointestinal pathogens, and understanding host-pathogen interactions is essential for developing vaccines and treatments. Moreover, the gut-associated lymphoid tissue (GALT) is a critical component of immune defense.

This session discusses mechanisms of infection, immune response, emerging antibiotic resistance, and advances in diagnostic and therapeutic strategies, including vaccines, probiotics, and antimicrobial stewardship.

Key Topics:

• Viral, bacterial, and parasitic infections

• Helicobacter pylori and gastric diseases

• Gut-associated immune responses

• Diarrheal diseases and dehydration

• Diagnostic tools: PCR, stool cultures

• Antibiotic resistance and treatment protocols

• Preventive measures and vaccination
