This paper deals with the global existence and boundedness of the solutions for the quasilinear chemotaxis system $$\left\{\begin{array}{ll}u_t=\nabla \cdot (D(u) \nabla u)- \nabla \cdot (u \chi(v) \nabla v), \quad \quad x \in \Omega, \quad t > 0,\\v_t = \Delta v-u f(v), \quad \quad \quad \quad \quad \quad \quad \quad \quad x \in \Omega, \quad t > 0,\end{array}\right.$$under homogeneous Neumann boundary conditions in a convex smooth bounded domain, with nonnegative initial data(for some θ >n) and. The given functionsandf(s) are supposed to be sufficiently smooth for alls≥ 0 and such thatf(0) = 0. This model describes the motion of the cells (e.g., bacteria) under the effect of gradients of the concentration of the oxygen that is consumed by the cells. It is proved that the corresponding initial boundary value problem possesses a unique global classical solution that is uniformly bounded inprovided that some technical conditions are fulfilled.
