(plural staphylococci), 1887, Modern Latin, the genus name, coined (on model of streptococcus) in 1882 by Scottish surgeon and bacteriologist Alexander Ogston (1844-1929), from Greek staphyle "bunch of grapes" (see staff (n.)) + Modern Latin coccus "spherical bacterium," from Greek kokkos "berry, grain" (see cocco-).
