What is antibiotic resistance in the human body?
Antibiotic resistance occurs when an antibiotic has ceased effectively control or kill bacterial growth in an organism; in other words, the bacteria have become "resistant" and continue to multiply in the presence of therapeutic levels of an antibiotic. When antibiotic resistance develops within the human body, often times another class of antibiotics is needed to control the bacterial infection from progressing.
