s. mutans can almost always be found in everyone's mouth. It is considered a part of the 'normal' flora of the human mouth.
On the other hand, s. mutans is also associated with tooth decay. This results when large colonies of s.mutans are exposed to adequate amounts of simple sugars over extended periods of time. This results in the production of acids, which destroy tooth enamel.
The key is adequate oral hygiene. Proper and frequent brushing and flossing can usually significantly reduce the numbers of s.mutans and sugars in the mouth, thereby reducing the resulting acids and tooth decay.
The anti-DNase-B (ADB) test is performed to determine a previous infection of a specific type of Streptococcus, group A beta-hemolytic Streptococcus.
The gelatin hydrolysis test is used to test if a microbe produces gelitinase. If the gelatin turns liquid that means gelatinase is present. Streptococcus is one of many strains that can be tested this way.
all i know about alcaligenes faecalis is that it is: gram negative rod shaped motile prime growth-37°c and that is oxidase and catalase positive hope this helps :D
Streptococcus pyogenes is a gram-positive bacterium caused by infections. It is tested by a catalase test that will show either a positive or negative reaction to streptococci.
It is positive for the metabolizing of glucose.
This test is most useful in evaluating suspected poststreptococcal disease following Streptococcus pyogenes infection, such as rheumatic fever.
Optochin is a test used only for determining if an isolate of alpha-hemolytic streptococcus is Streptococcus pneumoniae. In the clinical laboratory, it is not used for testing of gram negative rods such as E. coli.
