2010-08-13ZeitschriftenartikelDeterminants of tick-borne encephalitis in counties of southern Germany, 2001-2008 Background: Tick-borne encephalitis (TBE) virus can cause severe symptoms in humans. The incidence of this vector-borne pathogen in humans is characterised by spatial and temporal heterogeneity. To explain the variation ...

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 ...

2010-10-31ZeitschriftenartikelDirect Visualization of Peptide/MHC Complexes at the Surface and in the Intracellular Compartments of Cells Infected In Vivo by Leishmania major Protozoa and bacteria infect various types of phagocytic cells including macrophages, monocytes, dendritic cells and eosinophils. However, it is not clear which of these cells process and present microbial antigens in vivo ...

2007-09-06ZeitschriftenartikelDiscovery of herpesviruses in multi-infected primates using locked nucleic acids (LNA) and a bigenic PCR approach Targeting the highly conserved herpes DNA polymerase (DPOL) gene with PCR using panherpes degenerate primers is a powerful tool to universally detect unknown herpesviruses. However, vertebrate hosts are often infected with ...
-
2014-12-19ZeitschriftenartikelDiscrete and overlapping functions of peptidoglycan synthases in growth, cell division and virulence of Listeria monocytogenes Upon ingestion of contaminated food, Listeria monocytogenes can cause serious infections in humans that are normally treated with β-lactam antibiotics. These target Listeria's five high molecular weight penicillin-binding ...

2011-12-28ZeitschriftenartikelDiseases and causes of death in European bats: dynamics in disease susceptibility and infection rates. Background: Bats receive increasing attention in infectious disease studies, because of their well recognized status as reservoir species for various infectious agents. This is even more important, as bats with their ...

2009-04-22ZeitschriftenartikelDistribution and expression of porcine endogenous retroviruses in multi-transgenic pigs generated for xenotransplantation Background: Multi-transgenic pigs produced for use in xenotransplantation have to be screened for the presence and expression of porcine endogenous retroviruses (PERV) to select animals with low PERV load. The production ...
-
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 ...
-
2013-07-12ZeitschriftenartikelDNA Uptake by the Nosocomial Pathogen Acinetobacter baumannii Occurs during Movement along Wet Surfaces The emergence of Acinetobacter baumannii as an increasingly multidrug-resistant nosocomial pathogen largely relies on acquisition of resistance genes via horizontal gene transfer. Here, we demonstrate that many clinical ...
-
2012-07-25ZeitschriftenartikelEastern Chimpanzees, but not Bonobos, Represent a Simian Immunodeficiency Virus Reservoir Chimpanzees in west central Africa (Pan troglodytes troglodytes) are endemically infected with simian immunodeficiency viruses (SIVcpzPtt) that have crossed the species barrier to humans and gorillas on at least five ...
-
2013-10-21ZeitschriftenartikelEvaluation of Non-Invasive Biological Samples to Monitor Staphylococcus aureus Colonization in Great Apes and Lemurs Introduction: Reintroduction of endangered animals as part of conservational programs bears the risk of importing human pathogens from the sanctuary to the natural habitat. One bacterial pathogen that serves as a model ...

2015-06-25ZeitschriftenartikelEvent-based surveillance of food- and waterborne diseases in Europe: ‘urgent inquiries’ (outbreak alerts) during 2008 to 2013 During 2008 to 2013, 215 outbreak alerts, also known as ‘urgent inquiries’ (UI), for food- and waterborne diseases were launched in Europe, the majority of them (135; 63%) being related to salmonellosis. For 110 (51%) UI, ...
-
2015-05-29ZeitschriftenartikelEvidence for a Novel Mechanism of Influenza Virus-Induced Type I Interferon Expression by a Defective RNA-Encoded Protein Influenza A virus (IAV) defective RNAs are generated as byproducts of error-prone viral RNA replication. They are commonly derived from the larger segments of the viral genome and harbor deletions of various sizes resulting ...
-
2013-11-14ZeitschriftenartikelEvidence for the transmission of Salmonella from reptiles to children in Germany, July 2010 to October 2011 This study examines the Salmonella status in reptiles kept in households with children suffering from gastroenteritis due to an exotic Salmonella serovar, to obtain information on possible transmission paths. A number of ...
-
2009-11-14ZeitschriftenartikelExamining Landscape Factors Influencing Relative Distribution of Mosquito Genera and Frequency of Virus Infection Mosquito-borne infections cause some of the most debilitating human diseases, including yellow fever and malaria, yet we lack an understanding of how disease risk scales with human-driven habitat changes. We present an ...
-
2003-01-01ZeitschriftenartikelExpression of ICOS In Vivo Defines CD4+ Effector T Cells with High Inflammatory Potential and a Strong Bias for Secretion of Interleukin 10 The studies performed to date analyzed the overall participation of the inducible costimulator (ICOS) in model diseases, but did not yield information on the nature and function of ICOS-expressing T cells in vivo. We ...
