Question

Which of these are a cocci occurring in single or pairs?
A. Diplococci
B. Streptococci
C. Tetracocci
D. None of the above

Answer 1

Hint:
Before we proceed into the problem, it is important to know the definitions of cocci.
Cocci are a type of bacteria, and the three that you listed are part of this group. Coccidiosis is a serious infection caused by these types of bacteria, and it can be deadly if not treated quickly.

Complete answer:
Cocci are an acronym for the bacterium, and it refers to a single or pair of bacteria that can cause problems. Some of the most common causes of cocci include pneumonia, urinary tract infections (UTIs), intestinal infections, ear infections, sinusitis, and gum disease. Cocci easily spread through contact with respiratory secretions or saliva semen/vaginal fluid. They can also be passed from one person to another via contaminated surfaces such as countertops or doorknobs.
Whenever you have symptoms suggestive of coccidioidomycosis (such as fever, malaise, headache) – which may occur weeks or even months after the initial exposure – it is important to consult your doctor and undergo testing for this potentially deadly bacterial syndrome.
Therefore, cocci occurring in single or pairs are Diplococci.

Option ‘A’ is correct

Note:
Diplococci are a type of bacteria that can cause infections in the throat, nose, and lungs. These infections are often referred to as pneumonia, and they can be particularly dangerous if not treated promptly. Diplococci tend to spread through respiratory secretions (such as saliva or mucus), so it is important for people with these types of pneumonia to take antibiotics regularly unless their doctor advises otherwise. Additionally, those who are vulnerable to complications from pneumonia should avoid close contact with other people and keep their environment clean.
