erysipelas arthritis in swine: concentrations of complement and third component of complement in synovia.concentrations of hemolytic complement and of 3rd component of complement were determined in serums and in synovia of normal and arthritic joints in swine affected with arthritis experimentally produced by the inoculation of erysipelothrix rhusiopathiae. mean concentrations of complement in arthritic joints were increased from 24.7 to 37.5 50% hemolytic units of complement per milliliter. third component of complement, expressed as a percentage of the serum concentration, was increased from a me ...19761247196
specific detection and semiquantitation of microorganisms in tissue by nucleic acid hybridization. ii. investigation of synovia from pigs with chronic erysipelothrix arthritis.synovial tissues from animals with chronic erysipelothrix arthritis were examined by a technique based on rna-dna hybridization in an attempt to detect the inducing organism, erysipelothrix insidiosa (ei). twelve synovial specimens from 5 animals whose joints lacked culturable ei also lacked ei detectable by this technique. because the technique is capable of detecting approximately one organism per 50 mammalian cells, it is concluded that no more than this number were present in the involved ti ...19761252268
