What bacteria is hardest to kill?

While the Gram-positive bugs methicillin-resistant Staphylococcus aureus (MRSA) and Clostridium difficile are the most well-known drug-resistant bacteria, many Gram-negative species are particularly hard to treat because they have an extra outer membrane that shields them from drugs.
