What is a non hemolytic transfusion?
Febrile nonhemolytic transfusion reactions (FNHTRs) are common, occurring with 1–3% of transfusions. FNHTR manifests as fever and/or chills without hemolysis occurring in the patient during or within 4 hours of transfusion cessation. Diagnosis is made by excluding other causes of fever.

Is non Type A strep contagious?
The risk of spread is greatest when an individual is ill, such as when people have strep throat or an infected wound. Individuals who carry the bacteria but have no symptoms are much less contagious. Treatment of an infected person with an appropriate antibiotic for 24 hours or longer eliminates contagiousness.
What are the most important groupable streptococci?

What are Group C and group G Streptococci?
Group C streptococci includes: Streptococcus equi, which causes a disease in horses S. zooepidemicuswhich causes infections in cattle and horses among other animals S. dysgalactiae Group G streptococci includes
