  "abstract": "In Xu and Kuang (\\textit{J. Phys. A: Math. Gen.} 39 (2006) L191), the authors claim that, for single-mode excited entangled coherent states $| \\Psi_{\\pm}(\\alpha,m)>$, \\textquotedblleft the photon excitations lead to the decrease of the concurrence in the strong field regime of $| \\alpha | ^{2}$ and the concurrence tends to zero when $| \\alpha | ^{2}\\to \\infty$\". This is wrong.",
