Comparatively high genetic connectivity of red deer management units in Saxony-Anhalt within a standardized supraregional framework

Julian Laumeier, Jette Diekmann, Hermann Willems, Natascha Schumann et autres

Abstract Maintaining genetic connectivity is a central requirement for the long-term persistence of wide-ranging wildlife populations in increasingly human-modified landscapes. Population genetic approaches provide valuable tools for evaluating connectivity patterns and identifying early signs of genetic isolation. However, robust supraregional comparisons are …

Occurrence of viral and bacterial pathogens in South American camelids in representative German flocks

Christian Menge, Stefanie Barth, Eva-Maria Bartl, Christian Berens et autres

Rapidly growing populations of South American camelids (SAC), introduced to Europe as non-indigenous species, have increased contacts at the livestock and human interfaces. This study assessed the occurrence of epizootic and zoonotic viral and bacterial pathogens of prime importance on 10 farms, …

High-resolution analysis of red deer (Cervus elaphus) management units in a Central European region of high human population density reveals severe effects on genetic diversity and differentiation

Julian Laumeier, Hermann Willems, Gerald Reiner

The threat of isolation to red deer (Cervus elaphus) has been described in numerous European studies. The consequences range from reduced genetic diversity and increased inbreeding to inbreeding depression. It has been shown that the underlying factors cannot be generalised, but vary …

Fine Mapping Identifies Candidate Genes Associated with Swine Inflammation and Necrosis Syndrome

Katharina Gerhards, Sabrina Becker, Josef Kühling, Joel Mickan et autres

Swine inflammation and necrosis syndrome (SINS) is a widespread disease in pigs, causing pain, suffering, and damage. Inflammation is documented at different levels based on clinical signs, histopathology, clinical chemistry, metabolomics and transcriptomics. The influence of sow and boar, as well as …

Genome-Wide Association Study Reveals Single Nucleotide Polymorphisms Associated with Tail Length and Tail Kinks in Piglets

Katharina Gerhards, Christiane Egerer, Sabrina Becker, Hermann Willems et autres

Tail docking is still used in pigs to reduce the prevalence of tail biting, although it is purely symptomatic and contrary to animal welfare. Genetic selection for shorter tails might, however, help to avoid tail docking and has therefore been proposed. A …

Screening for transcriptomic associations with Swine Inflammation and Necrosis Syndrome

Katharina Gerhards, Sabrina Becker, Josef Kuehling, Mirjam Lechner et autres

BACKGROUND: The recently identified swine inflammation and necrosis syndrome (SINS) affects tail, ears, teats, coronary bands, claws and heels of affected individuals. The primarily endogenous syndrome is based on vasculitis, thrombosis, and intimal proliferation, involving defence cells, interleukins, chemokines, and acute phase …

Field study on the suitability of oral fluid samples for monitoring of Lawsonia intracellularis and Brachyspira hyodysenteriae by multiplex qPCR under field conditions

Matthias Eddicks, Gerald Reiner, Sigena Junker, Hermann Willems et autres

BACKGROUND: Monitoring or surveillance of infectious diseases is crucial in terms of herd health management of livestock. Investigations of oral fluids have become an animal friendly routine strategy to monitor respiratory pathogens in pigs. Less is known about the suitability of oral …

Genetic differentiation of wild boar populations in a region affected by African swine fever

U. Simon, Katharina Gerhards, Senta Becker, Hermann Willems et autres

Abstract In the European Union, African swine fever (ASF) affects wild boar ( Sus scrofa ) populations in several Member States. Knowledge of population connectivity is important for the implementation of control measures, in particular the establishment of effective barriers. Population genetic …

GWAS reveals genomic associations with swine inflammation and necrosis syndrome

Katharina Gerhards, Sabrina Becker, Josef Kuehling, Mirjam Lechner et autres

The recently identified swine inflammation and necrosis syndrome (SINS) occurs in high prevalence from newborn piglets to fattening pigs and resembles an important concern for animal welfare. The primary endogenous syndrome affects the tail, ears, teats, coronary bands, claws and heels. The …
