Antibiotic resistance is when pathogens such as bacteria or fungi develop a resistance to antibiotics. This happens when some pathogens die, and others survive. The small number of pathogens that had a resistance to the antibiotic will reproduce more offspring that are also resistant to, and those offspring will reproduce even more offspring and so on. Eventually most pathogens will be resistant to the antibiotic, so antibiotics won't work.
