Figure 1. Amplification of Chlamydophila psittaci (Cp) DNA using PCR in ocular adnexal extranodal marginal zone B-cell lymphoma (EMZL). Six cases of 12 ocular adnexal EMZL showed positive bands and defined as Cp-positive samples, and the others were grouped as Cp-negative group. P, positive control for C. psittaci; N, negative control; L, size marker 485 (100-bp DNA ladder).
