Mazzotti Test for Onchocerciasis
This topic explains the Mazzotti test, a provocative diagnostic test for onchocerciasis. Zambian medical students will learn how a small dose of diethylcarbamazine (DEC) causes an allergic reaction (pruritus, rash) in infected individuals due to rapid killing of microfilariae. Understanding this test is important for historical context and for appreciating the immune response to dying microfilariae. While largely replaced by safer methods, this knowledge demonstrates understanding of onchocerciasis pathophysiology and is included in comprehensive tropical medicine education.
