A Bactéria "Vila Real de Santo António" (VRSA)

Sexta-feira, 18.04.14

Com origem no continente sul-americano onde habitam os nossos irmãos brasileiros, vem mais uma prova de que a utilização intensiva e indiscriminada de antibióticos, em vez de nos fazer ganhar a guerra como desejaria o nosso amigo e cientista Pasteur, apenas nos está a escancarar a porta para a nossa perdição – transformando um parceiro de estrada, numa besta infernal.


New MRSA Superbug Emerges in Brazilian Patient

A new, highly drug-resistant type of the superbug methicillin-resistant Staphylococcus aureus (MRSA) recently caused a fatal blood infection in a Brazilian patient, according to a new report.


The 35-year-old man, who was in poor health and had been in the hospital for a long time, was infected with a strain of MRSA that developed resistance — during his hospital stay — to the powerful antibiotic vancomycin, which is widely used to treat this infection.


Researchers found that unlike previous superbugs that were associated with hospitals, this vancomycin-resistant staph bacteria (VRSA) is genetically related to a MRSA strain that has been circulating in the United States and northern South America, according to the study, published today (April 17) in the New England Journal of Medicine. 


"This particular bug is genetically different from all the others that have been described before, and belongs to a clone that has been described before to cause infections in the community, and not in the hospital," said study researcher Dr. Cesar Arias, an infectious diseases scientist and an associate professor of medicine at the University of Texas.


These findings in the Brazilian patient's case "raise concerns that this particularly resistant contaminant can actually disseminate now much more easily than previously thought," Arias told Live Science.
