Which type of bacteria can appear in curved lines resembling a string of beads?

The type of bacteria that appears in curved lines resembling a string of beads is known as streptococci. This specific arrangement occurs due to the way streptococci divide; they do so in a manner that causes them to form chains or strings as they replicate and the daughter cells remain attached. This characteristic is a key distinguishing feature of streptococci, which can be further divided into various groups based on their hemolytic properties and other characteristics.

In contrast, diplococci are typically found in pairs, staphylococci cluster in grape-like formations, and bacilli are rod-shaped bacteria. Each type has distinct morphologies and growth patterns, which helps in their identification in microbiology. Understanding these differences is crucial for effective diagnostic and treatment approaches in various contexts, including nail and skin care practices where bacterial infections may be a concern.
