Scientists reveal how bacteria develop antibiotic resistance

A team of researchers has recently revealed more information about how some bacteria manage to resist antibiotics: genetics. They found 76 new types of resistance genes that make bacteria invulnerable to last-resort antibiotics. The research suggested that increasing number of infections caused by antibiotic-resistant bacteria is a rapidly growing global problem. Disease-causing bacteria become resistant through mutations of their own DNA or by acquiring resistance genes from other, often harmless, bacteria.
