Cryptosporidium was found on the conjunctiva of 6 SIV-infected immunod
eficient rhesus monkeys. Some affected membranes were inflamed. The co
njunctiva is a newly recognized site for disseminated Cryptosporidium
infection in spontaneously infected immunodeficient mammals, and clini
cians and investigators should be aware of its possible presence in im
munodeficient patients with disseminated cryptosporidiosis.
