The possible zoonotic spread of antimicrobial-resistant bacteria is controversial. This review discusses global molecular epidemiological data combining both analyses of the chromosomal background, using multilocus sequence typing (MLST), and analyses of plasmid (episomal) extended-spectrum β-lactamase (ESBL)/AmpC genes in Escherichia coli present in humans(More)
Wildlife is normally not exposed to clinically used antimicrobial agents but can acquire antimicrobial resistant bacteria through contact with humans, domesticated animals and the environment, where water polluted with feces seems to be the most important vector. Escherichia coli, an ubiquitous commensal bacterial species colonizing the intestinal tract of(More)
Following the Europe-wide ban of antimicrobial growth promoters, feed supplementation with zinc has increased in livestock breeding. In addition to possible beneficial effects on animal health, feed supplementation with heavy metals is known to influence the gut microbiota and might promote the spread of antimicrobial resistance via co-selection or other(More)
Zoonotic hepatitis E virus (HEV) infection in industrialised countries is thought to be caused by transmission from wild boar, domestic pig and deer as reservoir hosts. The detection of HEV-specific antibodies in rats and other rodents has suggested that these animals may represent an additional source for HEV transmission to human. Recently, a novel HEV(More)
OBJECTIVES To evaluate the possible occurrence of carbapenemase-producing Escherichia coli and Klebsiella spp. strains in domestic animals. METHODS Veterinary clinical E. coli (n = 1175) and Klebsiella spp. (n = 136) isolates consecutively collected from livestock and companion animals in Germany from June 2012 to October 2012 were screened for their(More)
Superantigens (SAGs) interact with host immune receptors to induce a massive release of inflammatory cytokines that can lead to toxic shock syndrome and death. Bacterial SAGs can be classified into five distinct evolutionary groups. Group V SAGs are characterized by the alpha3-beta8 loop, a unique approximately 15 amino acid residue extension that is(More)
The prognosis of cancer disease is worsened upon shedding of tumor cells from the primary tumor, which escape to the blood stream and form metastases at distant sites within the body. Inhibition of cell shedding from the primary tumor could therefore be exploited to avoid metastasis and delay the progression of the cancer disease. In the present study, we(More)
Software-as-a-Service (SaaS) applications are multi-tenant software applications that are delivered as highly configurable web services to individual customers, which are called tenants in this context. For reasons of complexity management and to lower maintenance cost, SaaS providers maintain and deploy a single version of the application code for all(More)
Some programming languages, especially dynamic programming languages, offer suitable mechanisms for the construction of internal domain-specific languages (DSL). Internal DSLs inherit the facilities of their host language such as the availability of libraries, frameworks, tool support, and other DSLs. When developing an internal DSL, there are two(More)
AIMS Lactobacilli strains with probiotic effects have been widely used in dairy products such as yoghurts as well as in food additives and pharmaceuticals. Despite their successful commercial application, the current species identification and quantification methods of the genus Lactobacillus are time-consuming and labour-intensive. METHODS AND RESULTS To(More)
