Boston is the birthplace of Cryptosporidium. This troublesome intestinal protozoan was described in 1910 by Edward Tyzzer, a medical parasitologist at Harvard, and largely forgotten until it was recognised as a serious pathogen in the 1980s.
I recently visited a colleague at Tufts University in Boston, Saul Tzipori, who is a distinguished professor and world expert on animal models for cryptosporidiosis.
Having come across from Kenya with diarrhoea, Cryptosporidium and other diarrhoeal agents were on my mind — and arguably in my gut.
