Word Origin and History for staphylococci

staphylococcus

n.

(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-). So called because the bacteria usually bunch together in irregular masses.
