What characteristic is associated with Streptococci?

  1. Pus forming and grows in chains

  2. Non-pus forming and exists as single cells

  3. Only found in anaerobic conditions

  4. Form chains but do not cause infections

The correct answer is: Pus forming and grows in chains

Streptococci are primarily known for their characteristic growth pattern, which involves forming chains or pairs. This arrangement is a result of their reproduction method, where they divide along one plane and remain attached to one another. Additionally, many types of streptococci can indeed be pus-forming; for instance, Streptococcus pyogenes is known to cause infections that often lead to pus formation, such as in cases of strep throat or skin infections. This dual nature of growth in chains and potential to cause pus-forming infections is crucial in understanding their medical significance, particularly in identifying and treating streptococcal infections.
