What does Streptococcus agalactiae cause in humans?

How do you get strep Agalactiae?
How do people get group B strep? In newborns, group B Streptococcus infection is acquired through direct contact with the bacteria while in the uterus or during birth; thus, the gestational bacterial infection is transmitted from the colonized mother to her newborn.
How did I get Streptococcus agalactiae?
Like many bacteria, GBS may be passed from one person to another through skin-to-skin contact, for example, hand contact, kissing, close physical contact, etc. As GBS is often found in the vagina and rectum of colonised women, it can be passed through sexual contact.
How do you test for Streptococcus agalactiae?
During a group B strep test, your health care provider will swab your vagina and rectum and send the samples to a lab for testing. In some cases, you might be given instructions on how to collect the samples yourself. You’ll need to repeat the group B strep test each time you’re pregnant.
Is Streptococcus agalactiae resistant to bacitracin?
It inhibits cell wall synthesis and disrupts the cell membrane. This test is commonly used to distinguish between the b-hemolytic streptococci: Streptococcus agalactiae (bacitracin resistant) and Streptococcus pyogenes (bacitracin sensitive).
Can Streptococcus agalactiae be cured?
Early recognition and treatment is important to cure GBS infection in adults. High doses of antibiotics such as penicillin should be administered and the full course taken. Most GBS infection can be treated successfully, although some people will require all the expertise of intensive care facilities.

Why does strep agalactiae make blood turn yellow?
That’s because Strep agalactiae makes a toxin called beta-hemolysin, that causes complete lysis of the hemoglobin in the red blood cells, making them blood agar change color from red to transparent yellow around the colonies. However, other Streptococcus species, like Strep pyogenes, are also beta hemolytic.
