DNA barcoding as a tool to monitor the diversity of endangered spring snails in an Austrian National Park.

The Kalkalpen National Park is situated in Upper Austria and contains more than 800 springs. The international importance of this Park is, from the perspective of nature conservation directives, highly significant (European Nature Reserve Natura 2000, recognised wetland of the Ramsar convention). In the current study, the hydrobioid fauna ('spring snails') of the Kalkalpen National Park was evaluated.

Factors influencing the detection of antibacterial-resistant Escherichia coli in faecal samples from individual cattle.

Aims: To investigate whether on-farm antibacterial usage (ABU), environmental antibacterial-resistant (ABR) Escherichia coli prevalence, sampling and sample handling methodologies are associated with ABR E. coli positivity in individual faecal samples from dairy heifers.

Methods And Results: Three hundred and sixty-four heifers from 37 farms were sampled via rectal or faecal pat sampling.

Limited phylogenetic overlap between fluoroquinolone-resistant Escherichia coli isolated on dairy farms and those causing bacteriuria in humans living in the same geographical region.

Background: Our primary aim was to test whether cattle-associated fluoroquinolone-resistant (FQ-R) Escherichia coli found on dairy farms are closely phylogenetically related to those causing bacteriuria in humans living in the same 50 × 50 km geographical region suggestive of farm-human sharing. Another aim was to identify risk factors for the presence of FQ-R E. coli on dairy farms.

Molecular Epidemiology of Escherichia coli Producing CTX-M and pAmpC β-Lactamases from Dairy Farms Identifies a Dominant Plasmid Encoding CTX-M-32 but No Evidence for Transmission to Humans in the Same Geographical Region.

Third-generation cephalosporin resistance (3GC-R) in is a rising problem in human and farmed-animal populations. We conducted whole-genome sequencing analysis of 138 representative 3GC-R isolates previously collected from dairy farms in southwest England and confirmed by PCR to carry acquired 3GC-R genes. This analysis identified (131 isolates encoding CTX-M-1, -14, -15, -and 32 and the novel variant CTX-M-214), (6 isolates), and (1 isolate).

Characterization of AmpC-hyperproducing Escherichia coli from humans and dairy farms collected in parallel in the same geographical region.

Objectives: To characterize putative AmpC-hyperproducing third-generation cephalosporin-resistant E. coli from dairy farms and their phylogenetic relationships; to identify risk factors for their presence; and to assess evidence for their zoonotic transmission into the local human population.

Methods: Proteomics was used to explain differences in antimicrobial susceptibility.

Posttraumatic stress disorder after minor trauma - A prospective cohort study.

Background: Posttraumatic stress disorder (PTSD) can arise as a reaction to a traumatic experience. While many data concerning PTSD in severely injured patients are available, little is known about this disease in slightly injured patients after road traffic accidents. It is rather assumed that PTSD does not exist after objectively slight injuries.

Data-driven approach to using individual cattle weights to estimate mean adult dairy cattle weight.

Background: Knowledge of accurate weights of cattle is crucial for effective dosing of individual animals and for reporting antimicrobial usage. For the first time, we provide an evidence-based estimate of the average weight of UK dairy cattle to better inform farmers, veterinarians and the scientific community.

Methods: Data were collected for 2747 lactating dairy cattle from 20 farms in the UK.

Evaluation of metrics for benchmarking antimicrobial use in the UK dairy industry.

The issue of antimicrobial resistance is of global concern across human and animal health. In 2016, the UK government committed to new targets for reducing antimicrobial use (AMU) in livestock. Although a number of metrics for quantifying AMU are defined in the literature, all give slightly different interpretations.

Emergence of distinct genetic variants in the population of primary Bartonella henselae isolates.

Bartonella henselae isolates from different hosts display a marked genetic heterogeneity, as determined by pulsed-field gel electrophoresis (PFGE). The aim of the present study was to determine whether different genetic variants may coexist within the population of distinct B. henselae isolates and could be detected by PFGE.
