2010-06-24ZeitschriftenartikelChronic norovirus infection after kidney transplantation: molecular evidence for immune-driven viral evolution. Background: Norovirus infection is the most common cause of acute self-limiting gastroenteritis. Only 3 cases of chronic norovirus infection in adult solid organ transplant recipients have been reported thus far. Methods: ...

2010-10-28ZeitschriftenartikelDifferentiation of Medically Important Euro-Asian Tick Species Ixodes ricinus, Ixodes persulcatus, Ixodes hexagonus, and Dermacentor reticulatus by Polymerase Chain Reaction Understanding epidemiology of the tick-borne pathogens requires the accurate identification of the vector ticks. Morphological analysis of ticks is difficult and often leads to misidentification. Molecular techniques offer ...

2012-05-01ZeitschriftenartikelDiversity of parvovirus 4-like viruses in humans, chimpanzees, and monkeys in hunter-prey relationships. During 2010–2011, we investigated interspecies transmission of partetraviruses between predators (humans and chimpanzees) and their prey (colobus monkeys) in Côte d’Ivoire. Despite widespread infection in all species ...

2011-09-15ZeitschriftenartikelEmergence of bla CTX-M-15, qnrB1 and aac(6′)-ib-cr resistance genes in Pantoea agglomerans and enterobacter cloacae from Nigeria (sub-Saharan Africa) Besides hyper-production of chromosomal AmpC β-lactamases, the expression of plasmid-encoded extended-spectrum β-lactamases (ESBL) in Enterobacter spp has increased in recent years. In this study, we characterized 10 ...

2009-04-22ZeitschriftenartikelGenetic variability of group A human respiratory syncytial virus strains circulating in Germany from 1998 to 2007. The variability between respiratory syncytial virus (RSV) strains is one of the features of RSV infections that might contribute to the ability of the virus to infect people repeatedly and cause yearly outbreaks. To study ...
