2008-05-28ZeitschriftenartikelInterspecies transmission of simian foamy virus in a natural predator-prey system Simian foamy viruses (SFV) are ancient retroviruses of primates and have coevolved with their host species for as many as 30 million years. Although humans are not naturally infected with foamy virus, infection is occasionally ...

2011-03-31ZeitschriftenartikelIS element IS16 as a molecular screening tool to identify hospital-associated strains of Enterococcus faecium Background: Hospital strains of Enterococcus faecium could be characterized and typed by various molecular methods (MLST, AFLP, MLVA) and allocated to a distinct clonal complex known as MLST CC17. However, these techniques ...

2009-10-16ZeitschriftenartikelLack of evidence for xenotropic murine leukemia virus-related virus(XMRV) in German prostate cancer patients Background: A novel gammaretrovirus named xenotropic murine leukemia virus-related virus (XMRV) has been recently identified and found to have a prevalence of 40% in prostate tumor samples from American patients carrying ...
-
2009-11-18ZeitschriftenartikelLymphocryptovirus phylogeny and the origins of Epstein-Barr virus. Specimens from wild and captive primates were collected, and searched for new members of the genus Lymphocryptovirus (subfamily Gammaherpesvirinae) utilising PCR for the DNA polymerase gene. Twenty-one new viruses were ...

2009-04-20ZeitschriftenartikelMalaria transmission in non-endemic areas: case report, review of the literature and implications for public health management In non-endemic areas, malaria is rare and locally acquired infections, particularly with Plasmodium falciparum, are exceptional events. The diagnosis is, therefore, likely to be delayed or missed in patients without a ...
