Introduction
Mycoplasma hyorhinis is a member of the Mycoplasmatales family. This bacterium is often found as a commensal in the respiratory tract of pigs. It is thought to facilitate and exacerbate the development of diseases such as porcine enzootic pneumonia and porcine reproductive and respiratory syndrome (PRRS). Rarely, it may cause mycoplasma arthritis, mycoplasmal polyserositis or mycoplasma septicaemia in piglets without the involvement of other bacteria. This presents as polyarthritis or polyserositis.
Clinical Signs & Diagnosis
A variety of clinical signs are seen in piglets less than 10 weeks old.
Lameness, polyserositis and joint swelling are the most common symptoms. A foul smelling aural discharge can occur secondary to otitis. Less specific signs include poor coat quality, pyrexia, cardiovascular, gastrointestinal, neurological and respiratory signs.
Bacterial culture, immunofluorescent antibody testing (IFAT), complement fixation test and haemagglutination can all be used to confirm diagnosis.
Treatment
Antibiotics are the treatment of choice.
