Quizplus · Accepted Answer

The physiologic classification divides the species into four groups: pyogenic streptococci, lactococci, enterococci, and viridans streptococci.The pyogenic streptococci are those that produce pus; these organisms are mostly b-hemolytic and constitute the majority of the Lancefield groups.The lactococci, members of the genus Lactococcus, are nonhemolytic organisms with Lancefield group N antigens that often are found in dairy products.The enterococci comprise those species found as part of the normal flora of the human intestines; this group of organisms belongs to the genus Enterococcus.
