- Like other cocci, streptococci are round bacteria. The species name is derived from Greek words meaning 'a chain' ( streptos) of berries ( coccus [Latinized from kokkos ]) and pus ( pyo )-forming (genes), because streptococcal cells tend to link in chains of round cells (see image) and a number of infections caused by the bacterium produce pus.
