Find common elements in a list of sublists

Suppose I have a list of sublists: d={{1, 19}, {1, 23}, {1, 5, 25}, {1, 17}, {1, 11}, {1, 5}} How do I find the elements common to all the sublists? I can do it using intersection: Intersection[dx[[1]], dx[[2]], dx[[3]], dx[[4]], dx[[5]], dx[[6]]] which yields, correctly, {1}, but what if the number of sublists in d is variable?
