A parasite is an organism that lives on or in a host organism and gets its food from or at the expense of its host. Parasites of humans include protozoans, helminths, and ecto-parasites (organisms that live on the external surface of a host). They are responsible for many diseases and are transmitted to their hosts most often through the ingestion of contaminated food, water or through the bite of an arthropod (e.g., a fly or tick), which can act as an intermediate host and as a vector. Parasitic diseases of humans are a major global health problem causing significant morbidity and mortality, especially in developing countries. Each year there are hundreds of millions of people infected with disease-causing parasites, particularly in tropical and subtropical regions of the world, resulting in an estimated one million deaths. Therefore, there is a dire need of novel anti-parasitic drugs. MCE has a unique collection of 450 compounds with validated anti-parasitic activity which offer researchers an opportunity to screen novel anti-parasitic targets. 更多产品详情查看：www.medchemexpress.cn/screening/antiparasitic-compound-library.html
