Fauci’s February 2022 response to Mace noted that 500 monkeys from Morgan Island were shipped to the NIH’s Rocky Mountain Laboratories, according to the congresswoman.
In 1937, Eddy and her colleagues studied multiple aspects of Mycobacterium leprae, the bacteria that causes leprosy, to gain valuable information for future diagnostic purposes. One study conducted by Eddy included finding new mediums on which to culture Mycobacterium leprae in labs. [ 24 ]
