Molekulare Analyse der Riboflavinsynthesegene von Bartonella henselae und Aufbau einer speziesspezifischen PCR unter Verwendung des ribC Gens
Die Familie der Bartonellaceae beinhaltet 18 Spezies, von denen bisher sieben im Zusammenhang mit Erkrankungen beim Menschen beschrieben wurden. Bartonellen gelten als Erreger der KKK, der BA und von Endokarditiden. Die Diagnostik stützt sich primär auf serologische Untersuchungen, welche im Falle …

Technical evaluation of a Real-time polymerase chain reaction (PCR) assay for the detection of Bartonella spp for diagnostic purposes
… but a recent report indicated that the bacterium Bartonella was the commonest cause of culture-negative endocarditis at a tertiary care facility in Cape Town, South Africa. This laboratory-based, non-clinical pilot study, evaluated the utility of a previously published real-time PCR assay for …

Bats as Bushmeat in Ghana
… presence of henipavirus antibodies and $\textit{Bartonella}$ bacteria in $\textit{Eidolon helvum}$ fruit bats in Ghana, as well as the potential for commercial hunting of fruit bats, led me to this project in Ghana, West Africa. I set out to: (1) delineate ways in which bats and their pathogens …

Characterization of the Diverse Substrate Specificities and Biological Roles of Polyamine Biosynthetic Enzymes in Microorganisms
… from species within Methanosarcina, Pseudomonas, Bartonella, Nitrosomonas, Thermotoga and Aquifex showed a strong preference for L-ornithine, while the enzyme from Vibrio vulnificus (VvL/ODC) had dual specificity functioning well on both L-ornithine and L-lysine. The X-ray structure of VvL/ODC was …
