Mycoplasma hyorhinis stimulates tumor metastasis in C57BL/6 mice. A. Verification of Mycoplasma hyorhinis infection in B16F10 cells by Western blot with PD4 antibody. B. Macroscopic documentation of lung metastasis lesions of mice injected with infected (+) or uninfected (-) B16F10 cells. C. The average numbers of metastatic lesions for each mouse. The infected group had more metastasis than the uninfected group (P < 0.05). D. The average weight of lungs of mice injected with B16F10 cells. No difference was observed (P > 0.05)
