William Campbell

William Campbell was a renowned American microbiologist and parasitologist who, along with Satoshi Ōmura, discovered a key compound derived from soil bacteria called avermectin. This discovery led to the development of ivermectin, a medication that effectively treats numerous parasitic infections such as river blindness and lymphatic filariasis. His work has had a profound impact on global health by helping to control and eliminate debilitating parasitic diseases, especially in developing countries. Campbell was awarded the Nobel Prize in Physiology or Medicine in 2015 for his significant contributions to medicine and disease control.
