a. Actually the statement given by the friend is absolutely correct. The person has developed a resistance against the antibiotic he had taken to treat the strep throat. The infection has redeveloped and when he had the same antibiotic for strep throat it will become ineffective.
b. This happens because he had stopped taken the complete course of the antibiotic as prescribed by the doctor. If the bacteria changes its shape or removes the effectiveness of the particular antibiotic, resistance develops. The infection has redeveloped may be due to any change in the bacteria or ineffectiveness of the particular drug.
