Hyalomma marginatum - A silent stowaway after vacation at the Adriatic Sea.

Hyalomma marginatum is an invasive tick species capable of transmitting pathogens that cause severe diseases such as Crimean-Congo hemorrhagic fever. In Austria, H. marginatum occurs sporadically, and migratory birds are believed to bring H.

Who infects whom?-Reconstructing infection chains of Mycobacterium avium ssp. paratuberculosis in an endemically infected dairy herd by use of genomic data.

Recent evidence of circulation of multiple strains within herds and mixed infections of cows marks the beginning of a rethink of our knowledge on Mycobacterium avium ssp. paratuberculosis (MAP) epidemiology. Strain typing opens new ways to investigate MAP transmission.

Evolutionary genomic and bacteria GWAS analysis of subsp. and dairy cattle Johne's disease phenotypes.

subsp. (MAP) is the causative agent of Johne's disease in ruminants, which has important health consequences for dairy cattle. The Regional Dairy Quality Management Alliance (RDQMA) project is a multistate research program involving MAP isolates taken from three intensively studied commercial dairy farms in the northeastern United States, which emphasized longitudinal data collection of both MAP isolates and animal health in three regional dairy herds for a period of about 7 years.

Machine learning to further improve the decision which boar ejaculates to process into artificial insemination doses.

Current artificial insemination (AI) laboratory practices assess semen quality of each boar ejaculate to decide which ones to process into AI doses. This decision is aided with two, world-wide used, motility parameters that come available through computer assisted semen analysis (CASA). This decision process, however, still results in AI doses with variable and sometimes suboptimal fertility outcomes (e.

Infection of Red Deer in Western Austria-Optimized Use of Pathology Data to Infer Infection Dynamics.

Austria is officially bovine tuberculosis (TB) free, but during the last decade the west of the country experienced sporadic TB cases in cattle. Free-ranging red deer are known to be the maintenance host of (.) in certain areas in Austria, where cattle can become infected on alpine pastures shared with deer.

A data-driven individual-based model of infectious disease in livestock operation: A validation study for paratuberculosis.

Chronic livestock diseases cause large financial loss and affect animal health and welfare. Controlling these diseases mostly requires precise information on both individual animal and population dynamics to inform the farmer's decisions, but even successful control programmes do by no means assure elimination. Mathematical models provide opportunities to test different control and elimination options rather than implementing them in real herds, but these models require robust parameter estimation and validation.

Stochastic spatio-temporal modelling of African swine fever spread in the European Union during the high risk period.

African swine fever (ASF) is a notifiable viral pig disease with high mortality and serious socio-economic consequences. Since ASF emerged in Georgia in 2007 the disease has spread to several neighbouring countries and cases have been detected in areas bordering the European Union (EU). It is uncertain how fast the virus would be able to spread within the unrestricted European trading area if it were introduced into the EU.

[Acceptance of alternative disease control strategies in the European Union].

The European Commission intends to change its animal disease control strategy following the slogan "Prevention is better than cure". Vaccination and diagnostics should play a major role in emergency situations. A policy paper regarding the use of vaccines has been discussed with all Member States and the main aspects were evaluated in a questionnaire.
