Research Abstract

Ankle arthritis was induced by a single subcutaneous infection od the Streptococcus dysgalactiae subspecies equisimilis strain RE378, which was isolated from a patient suffering from multiple organ failure due to septicaemia, into both hind footpads of human CD46-expressing transgenic(Tg) mice. The histopathological findings in the hind ankle sections of CD46 Tg mice showed the stimulation of osteoclast formation associated with inflammation of the synovial membrane. The comparative genome sequence analysis revealed that the 43 predicted virulence-related factors including putative adhesion proteins and nucleases.
