Global Spread of Healthcare Associated Multi-Drug Resistant Bacteria

In the era of modern travel, it should be of little surprise that the global spread of drug resistant, hospital acquired bacteria is a reality.

Here is an article on the global spread of drug resistant healthcare associated bacteria published in Clinical Infectious Diseases. 

The article highlights various trends in the travel of drug resistant pathogens. MRSA spread from the UK and North America across Europe and then Asia over more than a decade. VRE and KPC-producing Klebsiella pneumoniae followed a similar path some 20 years later. Recently, metallo-beta-lactamases originated in Asia.  Within a year,  almost every continent witnessed the appearance of metallo-beta-lactamase producing bacteria.  

Per the authors, global air travel likely facilitated rapid dissemination of the more recent drug resistant organisms. 

Microbial globalization.
