Figure 1From: Heavy metal exposure reverses genetic resistance to Chlamydia-induced arthritisJoint swelling and histopathology scores demonstrating exacerbation of Chlamydia-induced arthritis following a prior systemic exposure to mercuric chloride (HgCl2) (n = 8 in each group). The differences after HgCl2 exposure are significant (P < 0.005) in both joint swelling (a) and histopathological severity scores (b). Hg, mercury. Ct, Chlamydia trachomatis.Back to article page
