We present a 44-year-old man from a rural community in northern Ecuador who 
worked on a cattle farm where he was involved with primary veterinary care, 
including assistance during births (or calving) and placenta retention and 
artificial insemination, with minimal precautions. In September of 2009, quite 
abruptly, he developed asthenia and hypersomnia without any apparent cause or 
symptoms like fever, chills, or night sweats. On November 14, 2009, he suffered 
from pain and edema in the right testicle that coincided with pain in the 
abdomen. Clinical, serological, and bacteriological investigations confirmed the 
first case of unilateral orchitis in man in Ecuador caused by Brucella abortus 
biovar 1. Because brucellosis is a neglected disease, special attention should 
be given to it in the training of medical and veterinary students.
