To fend off sickness, plasma cells release proteins called antibodies. They find and kill viruses, bacteria, and other substances. But sometimes, plasma cells make abnormal proteins, which are the -Antibodies against M protein (only if it is the same strain) -There is many different strains, which is why a person can have strep throat more than once. A newborn baby patient comes in very fussy and having breathing problems.
