Query: Stochastic reaction-diffusion systems with H\"older continuous
  multiplicative noise   We prove pathwise uniqueness and strong existence of solutions for stochastic
reaction-diffusion systems with locally Lipschitz continuous reaction term of
polynomial growth and H\"older continuous multiplicative noise. Under
additional assumptions on the coefficients, we also prove positivity of the
solutions.
