a patient with streptococcal sore throat takes penicillin for 2days a prescribed 10days regimen.because he feels better he then saves the remaining penicillin for some other time.after 3more days,he suffers a relapse of the sore throat. discuss the probable cause of the relapse?
it relapsed since he failed to complete the course of antibiotics, and some bacteria causing the infection may not have been killed thus making the remaining bacteria stronger and resistant to the antibiotic.
