Acute disseminated encephalomyelitis due to a zoonotic co-infection.

ADEM is a serious neurological disease which occurs as an uncommon complication of certain infections that lead to formation of antibodies which attack the cells of the nervous system. It usually occurs after viral infections, but we came across a 12-year-old girl with ADEM who tested positive for simultaneous infection with two different micro-organisms, both not viruses. These microbes, called Leptospira and Brucella, are common in developing countries and usually lead to infection in individuals in close contact with animals, or with consumption of infected, unpasteurized animal products. Neurological symptoms are uncommon in both infections. However, our case highlights that both infections can occur together and lead to serious neurological illness which needs proper evaluation and a different kind of treatment so that patient has better recovery.
