What characteristics does a normal nasopharyngeal culture have?
Bacteria that normally grow in the nose cavity will be identified by a nasopharyngeal culture. These include nonhemolytic streptococci, alpha-hemolytic streptococci, some Neisseria species, and some types of staphylococci.
What is the plural of streptococcus?
The plural of streptococcus is streptococci.
Which streptococci are implicated in the development of dental caries?
The viridans streptococci
Are staphylococci bacteria that form a chain?
No, staphylococci bacteria are typically arranged in clusters resembling grapes, not in chains. Streptococci are examples of bacteria that form chains.
What is the scientific name for streptococci?
Streptococci are bacteria that belong to the genus Streptococcus. There are 27 species of Streptococcus bacteria. The most well known bacteria in the group is Streptococcus pyogenes which is the bacteria that causes Strep throat.
What is the plural form of the word streptococcus?
The plural form of the word "streptococcus" is "streptococci."
Why do alpha streptococci produce green color on blood agar?
All of the different streptococci are organized into three groups based on how they break down red blood cells, a process called hemolysis. The group of streptococci that perform alpha hemolysis are called alpha streptococci. In alpha hemolysis, the hydrogen peroxide produced by the streptococci oxidizes the blood's hemoglobin, turning it into methemoglobin, which is green in color.

What causes Sydenhams's?
Sydenham's is caused by certain types of streptococci called Group A beta-hemolytic streptococci or GAS bacteria.
What is the plural form of streptococcus?
streptococci
What enzyme distinguishes staphylococci from streptococci?
The enzyme catalase distinguishes staphylococci from streptococci. Staphylococci produce catalase, which breaks down hydrogen peroxide into water and oxygen, while streptococci do not produce catalase. This difference in catalase production allows for a simple biochemical test to differentiate between these two bacteria.
