  "abstract": "In a recent paper, de Freitas et al. [Phys. Rev. E 61, 6330 (2000)] presented simulational results for the critical exponents of the two-species reaction-diffusion system A + B -> 2B and B -> A in dimension d = 1. In particular, the correlation length exponent was found as \\nu = 2.21(5) in contradiction to the exact relation \\nu = 2/d. In this Comment, the symmetry arguments leading to exact critical exponents for the universality class of this reaction-diffusion system are concisely reconsidered.",
