Antibiotic exposure can 'prime' single-resistant bacteria to become multidrug-resistant. Researchers report that, for a bacterial pathogen already resistant to an antibiotic, prolonged exposure to that antibiotic not only boosted its ability to retain its resistance gene, but also made the pathogen more readily pick up and maintain resistance to a second antibiotic and become a dangerous, multidrug-resistant strain.

This is all about evolution and changing to survive. Everything that is 'alive' does it. Very interesting, but can be frightening, especially with viruses and such.
By changing their shape, some bacteria can grow more resilient to antibiotics. New research demonstrates how certain types of bacteria can adapt to long-term exposure to antibiotics by changing their shape. Source 4s.
Mouse study shows bacteriophage therapy could fight drug-resistant Klebsiella pneumoniae. Using viruses instead of antibiotics to tame troublesome drug-resistant bacteria is a promising strategy, known as bacteriophage or 'phage therapy.' Scientists have used two different bacteriophage viruses individually and then together to successfully treat research mice infected with multidrug-resistant Klebsiella pneumoniae sequence type 258 (ST258).
