Streptococci may be sexually transmitted, but do not usually cause genital disease.
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.

No, Streptococci are bacteria that form chains.
Pathogenic streptococci will be beta-hemolytic, while others will not.
Catalase. Staphylococci are catalase positive. Streptococci are catalase negative.
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.
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.
