Tabish QidwaiChapter 3 provides an extensive and up-to-date summary of the methods used to diagnose and treat protozoan infections. Millions of people are affected every year by these parasitic illnesses, which are caused by single-celled eukaryotic organisms known as protozoans. Several protozoan disorders, such as amoebic infections, trypanosomiasis, leishmaniasis, and malaria, are discussed in detail. The concept of drug repurposing, which offers several advantages, including shorter development timelines and reduced costs, is considered an alternative for several current antiparasitic drugs. Healthcare professionals, researchers, and students who want to learn more about the most recent developments in this area will find this chapter a useful resource. This chapter also highlights the principles and applications of modern diagnostic techniques, therapeutic philosophies, components, and upcoming therapeutic choices, along with highlighting the merits and demerits of former methods employed for the diagnosis of these protozoan diseases. This chapter equips the reader with a vital tool for combating protozoan diseases and enhancing patient care through the integration of scientific insights with practical guidance.en-USBioscienceEnvironment & AgricultureHealth and Social CareMedicineDentistryNursing & Allied HealthBook chapter
