Mycoplasma hyosynoviae in joints with arthritis in abattoir baconers

Acta Vet Scand. 1992;33(3):205-10. doi: 10.1186/BF03547310.

Abstract

The occurrence of Mycoplasma hyosynoviae in synovial fluid of baconers with chronic arthritis was studied at an abattoir. Cultural examination of synovial fluid samples from diseased tarsal joints of 50 animals from 42 herds yielded M. hyosynoviae in 10 cases from 8 herds. Streptococci were found in 6 cases from 6 other herds. M. hyosynoviae antigen was found in 1 of 47 of the samples, and antibody to the mycoplasma was found in 14 of 40 of the samples by ELISA test. The presence of M. hyosynoviae in a joint was usually accompanied by the corresponding antibody. In joints with streptococcal infection antibody to M. hyosynoviae could not be found.

Betydningen af M. hyosynoviae for udviklingen af de kroniske ledbetændelser, som optræder hos baconsvin på et slagteri er blevet undersøgt. Ved dyrkning fra 50 haseled af dyr fra 42 besætninger fandtes M. hyosynoviae i 10 tilfælde fra 8 besætninger, medens streptokokker fandtes i yderligere 6 tilfælde fra 6 andre besætninger. Med ELISA proceduren fandtes antigen af M. hyosynoviae i 1 af 47 af prøverne og korresponderende antistof i 14 af 40 af prøverne. Tilstedeværelse af M. hyosynoviae i led var sædvanligvis ledsaget af antistof mod mykoplasmen; dette var ikke tilfældet i prøver med fund af bakterier. Det må anses for sandsynligt, at M. hyosynoviae er årsag til mange af disse kroniske ledbetændelser, medens bakterier formodentlig er ansvarlige for de øvrige.
