Diplococci are a type of bacteria that grow in pairs, and one of the most well-known diseases caused by this type of bacteria is pneumonia, specifically caused by Streptococcus pneumoniae. This bacterium can lead to pneumococcal pneumonia, which is a serious respiratory infection characterized by symptoms such as cough, fever, and difficulty breathing. The ability of diplococci to proliferate and form colonies can contribute to the severity of the infection.

In contrast, other options listed involve different pathogens. Strep throat is caused by Streptococcus pyogenes, which is a type of cocci but not diplococci. Tetanus is caused by Clostridium tetani, a rod-shaped bacterium, and typhoid fever is caused by Salmonella typhi, which is a bacillus. Understanding these distinctions helps clarify why pneumonia is the primary condition associated with diplococci.
