A study done by researchers at the New Your University Center for Genomics and Systems Biology, found that some money from Manhattan bank carried 3,000 types of bacteria. Some of the bacteria on the dollar bills were associated with acne however, there was bacteria that can be found in the mouth and vagina. ABC News reported that bills found in the winter were more likely than those tested in the summer to carry bacteria that can cause pneumonia. This suggested that money could be one way of spreading germs.
There were some antibiotic resistant types of bacteria found on the money including the “superbug” methicillin-resistant Staphylococcus aureus (MRSA). Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterium that causes infections in different parts of the body. It’s tougher to treat than most strains of staphylococcus aureus — or staph — because it’s resistant to some commonly used antibiotics.
