The strept is the abbreviation of Streptococcus, gram positive bacteria responsible for causing systemic infection in human especially in throat. It is not present directly in blood but our body produce a specific antibody against him which is detected in blood and said positive Streptococcus. These bacteria can be killed by penicillin antibiotics.
I have the strep virus in my bloodstream that has caused many problems with my health includes some heart problems. Please be aware that according to what type of the bacteria he has in his bloodstream he may be able to spread the disease to others without having any symptoms of the disease. No normal antibiotics will treat this.
