Strep throat is caused by which bacterium?

Explanation:
Strep throat is caused by Group A Streptococcus, the bacterium Streptococcus pyogenes. This specific group is identified by a surface carbohydrate and is the classic organism associated with the throat infection called strep throat. The rapid strep test and most strep throat treatments target this Group A organism. Escherichia coli is primarily a gut bacterium and isn’t typically implicated in throat infections. Staphylococcus aureus tends to cause skin and wound infections more than throat infections. Streptococcus pneumoniae is a different species that commonly causes pneumonia, ear infections, and meningitis, not the classic strep throat presentation.
