Acute Blastocystis-Associated Appendicular Peritonitis in a Child, Casablanca, Morocco
Blastocystis is a genus of anaerobic protozoan parasites that infect humans and a vast range of animal species. Prevalence in humans varies from 0.5%–24% in industrialized countries to 30%–76% in developing countries (1,2). Classic clinical features of infection include gastrointestinal symptoms such as nausea, anorexia, flatulence, and acute or chronic diarrhea. Fever is usually absent. An association with irritable bowel syndrome and extraintestinal manifestations such as urticaria has been suggested (2). Reports about invasive infection or disseminated diseases are rare (3). Here, we report the case of a pediatric patient infected with Blastocystis that was manifested by gastroenteritis associated with suppurative appendicitis and peritonitis.
