What does streptococcal mean?
Streptococcal is an adjective meaning “relating to or caused by streptococci.” Streptococci are round bacteria, many of which live naturally in the human mouth, nose, and other parts of the body. The adjective is especially common in medical and biological contexts, as in “streptococcal infection,” “streptococcal pharyngitis” (strep throat), and “group A streptococcal disease.” Some species of Streptococcus can cause significant illnesses, including strep throat, scarlet fever, and certain rare forms of pneumonia or toxic shock. The term is technical rather than conversational, but it is widely understood in healthcare and scientific writing. It can also describe tests, antibodies, or treatment methods connected with these bacteria. Although the adjective has no direct antonym, it should not be confused with staphylococcal, which refers to a different genus of bacteria.

Where does streptococcal come from?
The word comes from New Latin, combining the Greek-derived prefix strepto- meaning “twisted” or “chain-like” with coccus, from Greek kokkos, “berry.” Streptococcus refers to the characteristic chain-like arrangement of these spherical bacteria. The adjective streptococcal was developed from this genus name and is now used widely in medicine and microbiology.
