Carrión’s disease is an emerging but neglected 24 tropical illness endemic to Peru, Colombia, and Ecuador. B. bacilliformis is spread between 25 humans through the bite of female phlebotomine sand flies. -

Furthermore, I dedicate this thesis to my parents, for their unwavering confidence in me and their desire to help me do what I love. iii ABSTRACT The pathogenicity of Arcobacter butzleri remains enigmatic, in part due to a lack of genomic data and tools for comprehensive detection and genotyping of this bacterium. Comparative whole genome sequence analysis was employed to develop a high throughput and high resolution subtyping method representative of whole genome phylogeny. In addition, primers targeting a taxon-specific gene (quinohemoprotein amine dehydrogenase) were designed to detect and quantitate A. -

Drylands Soil Bacterial Community Is Affected by Land Use Change and Different Irrigation Practices in the Mezquital Valley
www.nature.com/scientificreports OPEN Drylands soil bacterial community is afected by land use change and diferent irrigation practices in the Received: 23 June 2017 Accepted: 3 January 2018 Mezquital Valley, Mexico Published: xx xx xxxx Kathia Lüneberg1, Dominik Schneider2, Christina Siebe1 & Rolf Daniel 2 Dryland agriculture nourishes one third of global population, although crop irrigation is often mandatory. As freshwater sources are scarce, treated and untreated wastewater is increasingly used for irrigation. Here, we investigated how the transformation of semiarid shrubland into rainfed farming or irrigated agriculture with freshwater, dam-stored or untreated wastewater afects the total (DNA-based) and active (RNA-based) soil bacterial community composition, diversity, and functionality. To do this we collected soil samples during the dry and rainy seasons and isolated DNA and RNA. Soil moisture, sodium content and pH were the strongest drivers of the bacterial community composition. We found lineage-specifc adaptations to drought and sodium content in specifc land use systems. Predicted functionality profles revealed gene abundances involved in nitrogen, carbon and phosphorous cycles difered among land use systems and season. Freshwater irrigated bacterial community is taxonomically and functionally susceptible to seasonal environmental changes, while wastewater irrigated ones are taxonomically susceptible but functionally resistant to them. Additionally, we identifed potentially harmful human and phytopathogens. The analyses of 16 S rRNA genes, its transcripts and deduced functional profles provided extensive understanding of the short- term and long-term responses of bacterial communities associated to land use, seasonality, and water quality used for irrigation in drylands. Drylands are defned as regions with arid, semi-arid, and dry sub humid climate with an annual precipitation/ evapotranspiration potential ratio (P/PET)1 ranging from 0.05 to 0.652. -

Aliarcobacter Butzleri from Water Poultry: Insights Into Antimicrobial Resistance, Virulence and Heavy Metal Resistance

This species is an emerging foodborne and zoonotic pathogen because the bacteria can be transmitted by contaminated food or water and can cause acute enteritis in humans. Currently, there is no database to identify antimicrobial/heavy metal resistance and virulence-associated genes specific for A. butzleri. The aim of this study was to investigate the antimicrobial susceptibility and resistance profile of two A. butzleri isolates from Muscovy ducks (Cairina moschata) reared on a water poultry farm in Thuringia, Germany, and to create a database to fill this capability gap. The taxonomic classification revealed that the isolates belong to the Aliarcobacter gen. nov. as A. butzleri comb. nov. The antibiotic susceptibility was determined using the gradient strip method. While one of the isolates was resistant to five antibiotics, the other isolate was resistant to only two antibiotics. The presence of antimicrobial/heavy metal resistance genes and virulence determinants was determined using two custom-made databases. -

It was found that these organisms constitute a distinct cluster within the genus Moraxelca. Since they differ genotypically as well as phenotypically from previously described Moraxeh species, a new species, Moruxella canis, is proposed to accommodate these isolates. The type strain is LMG 11194 (= N7 = CCUG 8415A). During the testing of the specificity and reliability of DNA selected on the basis of different criteria.
