Atkinson in Scott's ill-fated Terra Nova Expedition. He has written about the history of parasitology in Antarctic exploration, including the work of surgeon Edward L. įrom 1990 to 2010, when he retired, Campbell was a research fellow at Drew University in Madison, N.J., where he supervised undergraduate research and taught courses in parasitology. We have a moral obligation to look after each other, but we're also naturally obligated to look after our own needs. One part of the world affects another part. It would be disastrous to neglect the diseases of the developing world. The greatest challenge for science is to think globally, think simply and act accordingly. As of 2013, the Carter Center independently verified that the disease had been eradicated in Colombia, Ecuador, and Mexico. As of 2001 an estimated 25 million people were being treated each year, in a total of 33 countries in sub-Saharan Africa, Latin America, and the Middle East. With the World Health Organization they created an "unprecedented" drug donation program, with the intention of wiping out river blindness. Campbell was instrumental in that decision. In 1987, Merck decided to donate Mectizan to developing countries. The research of Satoshi Ōmura, William Campbell, and their co-workers created a new class of drugs for the treatment of parasites. Merck went on to study the treatment of elephantiasis. Taken orally, the drug paralyses and sterilises the parasitic worm that causes the illness.

In 1981, Merck carried out successful Phase 1 treatment trials in Senegal and France on river blindness. In 1978, having identified a successful treatment for a type of worms affecting horses, Campbell realised that similar treatments might be useful against related types of worms that affect humans. After further modification, it was named ivermectin (generic) or Mectizan. From the sample Streptomyces avermitilis, naturally produced in soil, he derived macrocyclic lactone. Campbell led a team at Merck in studying Ōmura's cultures and examining their effectiveness in treating parasites in domestic and farm animals. Japanese microbiologist Satoshi Ōmura isolated and cultured many varieties of natural soil-based bacteria from the group Streptomyces. Ĭampbell is best known for his work on parasitic diseases. Thiabendazole is also used to treat trichinosis in humans.

One of his discoveries while at Merck was the fungicide thiabendazole, used to treat potato blight, historically a scourge of Ireland. įrom 1957 to 1990 Campbell worked at Merck Institute for Therapeutic Research, and from 1984 to 1990 he was a Senior Scientist and Director with Assay Research and Development. He then attended the University of Wisconsin–Madison on a Fulbright Scholarship, earning his PhD degree in 1957 for work on the liver fluke, a parasite affecting sheep. He studied at Trinity College, Dublin with James Desmond Smyth, graduating in 1952 with first class honours in Zoology.
