Persistent cotton fever is often infective endocarditis. Antibiotic treatment lowers the risk of embolic complications in people with infective endocarditis. Infections occur via ingestion of infective larvae from contaminated vegetables or water. High-dose antibiotics are the cornerstone of treatment for infective endocarditis. Damaged valves and endocardium contribute to the development of infective endocarditis. Multiple case reports of infective endocarditis caused by unusual organisms have been published. Infection in mammals occurs upon ingestion of infective filariform (L3) larvae. Manson surmised that infected mosquitoes drowned and infective larvae were ingested in water. As many as 50% of people with infective endocarditis may experience embolic complications. The oocysts are mature and infective upon being excreted. It may be acute or chronic, infective or autoimmune. It can be a symptom of infective or neoplastic processes. Humans contract infective cysticerci by eating raw or undercooked meat. Other studies suggest hereditary, neurodegenerative, genetic and infective contributions. Their life cycle alternates between a swimming trophozoite and an infective, resistant cyst.
