Bacilli that remain attached in chains after cell division.
The killing of streptococci, a type of bacteria.
A genus of spherical Gram-positive bacteria that usually occur in pairs or chains; most strains are nonmotile.
Most species are parasites or pathogens of animals, often occurring in the respiratory or alimentary tracts.
Some species are hemolytic; that is, they destroy red blood cells, and cause such diseases as scarlet fever and rheumatic fever.
Streptococci are killed by pasteurization and common disinfectants; penicillin, tetracycline, and other antibiotics are effective against hemolytic strains.
