The susceptibilities of C3H/HeN, BALB/c, and C57BL/6N mouse strains to grou
p B streptococci (GBS) infection were evaluated. C3H/HeN mice developed sev
ere polyarthitis; mild lesions and no lesions were observed in BALB/c and C
57BL/6N mice, respectively, a correlation between the severity of arthritis
, the number of GBS in the joints, and local interleukin-6 and interleukin-
1 beta production was evident.
