Hi. The answer is yes.

You can refer to my review which is now published ahead of print in the "infectious diseases in clinical practice" journal. The available link is:

http://journals.lww.com/infectdis/Abstract/publishahead/VanA_Positive_Vancomycin_Resistant_Staphylococcus.99544.aspx

Some new reports of VRSA in the literature:

1st case in Europe, 1st case in Portugal:

http://download.thelancet.com/pdfs/journals/lancet/PIIS0140673613612192.pdf?id=aaasj9kHuRIIA41vvCJru

1st case in South America, 1st case in Brazil:

http://www.promedmail.org/direct.php?id=20130630.1800166

And we have also recently found a new VRSA from south of Iran, you can find the preliminary report of this unusual strain at: http://www.ncbi.nlm.nih.gov/pubmed/23880172.

Does anybody know any other report of VRSA apart from those that I have mentioned?

I would be very glad if other researchers help to find the other possible relevant articles.
