title: [Clinical and histopathological findings in mycoplasmal polyarthritis of rats. III. Course of infection during the weeks 7-30 and 54-61 (author's transl)].
abstract: Clinical, microbiological and histological findings of the late phase of experimentally induced Mycoplasma-polyarthritis in rats are described. Investigations were carried out between the 7.-30. week and between the 54-61. week p.i. M. arthritidis could be reisolated from affected joints regularly up to the 7th week p.i. Thereafter until 12th week only occasional recovery was possible. The healing process of affected joints dominated signs of arthritis which could be confirmed histologically as a purulent process.  The alterations of carpal and tarsal joints were divided into purulent, chronic deforming and chronic minor lesions. The findings derived from investigation of joints and parenchymatous organs during the course of the disease are discussed.
