What bacteria are arranged in curved lines and can cause strep throat?

Streptococci are spherical bacteria that tend to form chains or curved lines when they divide. This arrangement is characteristic of their cellular structure. They are known to be responsible for a variety of infections, including strep throat, which is a common ailment caused by group A Streptococcus (Streptococcus pyogenes). In the context of strep throat, these bacteria invade the throat and can lead to inflammation and pain, manifesting the typical symptoms associated with the infection.

The other types of bacteria mentioned do not share this specific arrangement or association with strep throat. Bacilli are rod-shaped bacteria, spirilla are spiral-shaped, and staphylococci form clusters resembling grapes, none of which are responsible for strep throat. Understanding the arrangement and classification of bacteria is crucial in identifying and treating infections effectively.
