Reactive arthritis (ReA) has been defined as a sterile synovitis developing 1-3 weeks after an infection in the genitourinary or gastrointestinal tract. The classical microbes in the gastrointestinal tract include Yersinia, Salmonella and Shigella. At the time of arthritis, stool cultures are negative and the background of ReA is usually confirmed by serological methods. However, there are no international standards for the tests, and techniques vary greatly. In a case of child ReA, we identified the potential bacterial trigger by studying the antibody response to different components of three candidate bacteria.
