Methicillin-resistant Staphylococcus aureus (MRSA) are bacteria that can cause infections on the skin (such as cellulitis), on burned areas of the body, and around wounds where invasive devices like feeding tubes and catheters enter the body. The most possible place you are infected by MRSA is in hospitals.
MRSA can also infect the eyes, bones, heart, or blood. Unlike regular staph infections, MRSA is resistant to many commonly used antibiotics. It means it is hard to treat and the process is painful and expensive.
NDM-1 represent New Delhi metallo-beta-lactamase . It likes a flu in bacteria. A bacterium can get NDM-1 by simply touch a bacterium which is with NDM-1. Once a bacterium got NDM-1, it will have the ability to resist most of antibiotics. Moreover DNM-1 will transmit to its “children” and even other bacterial. The infection by those bacterial is hard to cure.
The NDM-1 enzyme was named after New Delhi, the capital city of India, as it was first described by Yong et al. in December 2009 in a Swedish national who fell ill with an antibiotic-resistant bacterial infection that he acquired in India.
In May 2010, a case of infection with E. coli expressing NDM-1 was reported in Coventry in the United Kingdom.
As of June 2010, there were three reported cases of Enterobacteriaceae isolates bearing this newly described resistance mechanism in the US, the CDC stated that "All three U.S. isolates were from patients who received recent medical care in India."
