Reactive arthritis due to zoophilic (canine) sexual intercourse.

Reactive arthritis (ReA) is defined as a joint inflammation triggered by a distant infection, with no cultivable microbes in the joints. Although efforts have been made to characterize the microorganism linked to ReA, no definite common feature has so far emerged. Here we present a case of ReA which occurred after a zoophilic (canine genus) sexual intercourse.
