Specialised neural systems for encoding faces and face emotion cues have been found in sheep which are very similar to those described in human and non-human primates. Sheep exhibit highly sophisticated face identity and face emotion discrimination skills, use configural cues and also have a right hemisphere dominance in face processing. Various neuroanatomical approaches have identified the di...
In the past, architectures of Augmented Reality systems have been widely different and taylored to specific tasks. In this paper, we use the example of the SHEEP game to show how the structural flexibility of DWARF, our componentbased Distributed Wearable Augmented Reality Framework, facilitates a rapid prototyping and online development process for building, debugging and altering a complex, d...
Despite much attention, history of sheep (Ovis aries) evolution, including its dating, demographic trajectory and geographic spread, remains controversial. To address these questions, we generated 45 complete and 875 partial mitogenomic sequences, and performed a meta-analysis of these and published ovine mitochondrial DNA sequences (n = 3,229) across Eurasia. We inferred that O. orientalis and...
Two new large animal models of Huntington's disease (HD) have been developed recently, an old world monkey (macaque) and a sheep. Macaques, with their large brains and complex repertoire of behaviors are the 'gold-standard' laboratory animals for testing cognitive function, but there are many practical and ethical issues that must be resolved before HD macaques can be used for pre-clinical rese...
We report for the first time mecC-positive methicillin-resistant Staphylococcus aureus (mecC-MRSA) in livestock in Spain. One isolate (sequence type 130) was found in milk samples among 601 S. aureus isolates obtained from 229 dairy sheep farms. This finding highlights the potential for zoonotic transmission of mecC-positive MRSA and the need for surveillance programs to monitor its presence an...
Wild and domestic animal populations are known to be sources and reservoirs of emerging diseases. There is also a growing recognition that horizontal genetic transfer (HGT) plays an important role in bacterial pathogenesis. We used molecular phylogenetic methods to assess diversity and cross-transmission rates of Pasteurellaceae bacteria in populations of bighorn sheep, Dall's sheep, domestic s...
Abstract Bluetongue (BT) is an economically important arboviral disease of sheep, cattle, goats, and wild ruminants, particularly in America Europe. However, it has remained uncontrolled due to the evolution >32 serologically distinct BT virus (BTV) serotypes lack broad-spectrum vaccines. While outer VP2 VP5 proteins, involved cell penetration, are less conserved, certain core BTV protei...
Footrot causes 70-90% of lameness in sheep in Great Britain. With approximately 5% of 18 million adult sheep lame at any one time, it costs the UK sheep industry £24-84 million per year. The Gram-negative anaerobe Dichelobacter nodosus is the causative agent, with disease severity influenced by bacterial load, virulence, and climate. The aim of the current study was to characterize strains of D...
