PEREYRA, N. B. et al. Detection of Mycoplasma suis in clinical cases with postweaning multisystemic wasting syndrome in swine. Rev. argent. microbiol. [online]. 2006, vol.38, n.3, pp.130-133. ISSN 0325-7541.

Mycoplasma suis is a swine erythrocyte obligatory parasite. Its presence may result in chronic or acute anaemia in different pig categories. It is considered that the postweaning multisystemic wasting syndrome (PMWS) is caused by porcine circovirus type 2, but some aspects of the pathogenesis remain unknown. PMWS signs are impaired weight gain, anaemia and jaundice in 5 to 12 week-old pigs that suffer from immunosuppression and bacterial co-infections. The pigs with signs of these diseases on three porcine farms were studied. Compatible M. suis forms in blood smears and typical PMWS lesions in tissue cuts were seen. This is the first communication of the clinical association between these two entities.

Keywords : Mycoplasma suis; PMWS; PCV-2; Eperythrozoon suis; co-infection.
