Final answer:
The term "strept/o" in medical terminology refers to a clustered, chain-like arrangement of bacteria, particularly used in the context of the genus Streptococcus, which forms chains of cocci.
Step-by-step explanation:
The combining form "strept/o" in medical terminology, as found in the term streptococcus, typically refers to a clustered, chain-like arrangement of bacteria. More specifically, this term derives from the Greek word for twisted chain and denotes the characteristic appearance of these bacteria.
The genus Streptococcus comprises several species responsible for various infectious diseases in humans, and they are known for forming chains of cocci. It's also important to note that within the category of cocci bacteria, there are different types of arrangements apart from chains (streptococci), such as clusters (staphylococci).
