BACKGROUND: Non-invasive evaluation of muscle perfusion using near infrared spectroscopy (NIRS) coupled with a vascular occlusion test (VOT) may provide an early and simple marker of altered perfusion and microcirculatory function in sepsis. OBJECTIVE: To compare the time-course of NIRS-derived variables with systemic measures of perfusion in an experimental model of peritonitis. METHODS: Peritonitis was induced in eight anesthetized, mechanically ventilated, adult sheep (24-34 Kg), by injecting autologous feces into the peritoneal cavity...

Although a significant decrease has been reported in the incidence of diphteria in many regions of the world following the routine diphtheria immunization programs, the emergence of new cases indicated that toxigenic strains are still circulating in the community. Diphtheria vaccine does not provide protection against asymptomatic carriage and colonization of non-toxigenic Corynebacterium diphtheriae. It is a known fact that invasive infections may arise from non-toxigenic C.diphtheriae strains that the non-toxigenic strains can become toxigenic strains leading to diphteria...

REVIEW
Peng Li, Guoyao Wu
Glycine, proline, and hydroxyproline (Hyp) contribute to 57% of total amino acids (AAs) in collagen, which accounts for one-third of proteins in animals. As the most abundant protein in the body, collagen is essential to maintain the normal structure and strength of connective tissue, such as bones, skin, cartilage, and blood vessels. Mammals, birds, and fish can synthesize: (1) glycine from threonine, serine, choline, and Hyp; (2) proline from arginine; and (3) Hyp from proline residues in collagen, in a cell- and tissue-specific manner...

BACKGROUND: Chlamydia psittaci and Chlamydia pecorum are important veterinary pathogens, with the former also being responsible for zoonoses, and the latter adversely affecting koala populations in Australia and livestock globally. The rapid detection of these organisms is still challenging, particularly at the point-of-care (POC). In the present study, we developed and evaluated rapid, sensitive and robust C. psittaci-specific and C. pecorum-specific Loop Mediated Isothermal Amplification (LAMP) assays for detection of these pathogens...

DNA methylation of regulatory and growth-related genes contributes to fetal programming which is important for maintaining the correct development of three germ layers of the embryo that develope into different tissues and organs, and which persists into adult life. In this study, a preliminary epigenetic screen was performed to define genomic regions that are involved in fetal epigenome remodeling. Embryonic ectodermic tissues (origin of nervous tissue), mesenchymal tissues (origin of connective and muscular tissues), and foregut endoderm tissues (origin of epithelial tissue), from day 28 sheep fetuses were collected and the distribution of methylated CpGs was analyzed using whole-genome bisulfite sequencing...

We explored the strength of implicit social inferences in adolescents with and without Autism Spectrum Disorder (ASD) using a chasing paradigm in which participants judged the absence/presence of a chase within a display of four seemingly randomly moving dots. While two of these dots always moved randomly, the two others could fulfill the role of being either the chasing (wolf) or chased (sheep) dot. In the chase-present (but not the chase-absent) trials the wolf displayed chasing behavior defined by the degree to which the dot reliably moved towards the sheep (chasing subtlety)...

The tick-borne bacterium Anaplasma ovis is a widely distributed pathogen affecting sheep, goats and wild ruminants. Here, the HL-60 human promyelocytic leukemia cell line was used to isolate A. ovis from PCR-positive sheep and goats in Heilongjiang Province, China. Two weeks after inoculation, morulae were observed in cytoplasmic vacuoles in four different HL-60 cultures. Confocal microscopy using a Cy3-labeled A. ovis-specific probe confirmed that the HL-60 cells were infected with A. ovis. Cells from the 6th HL-60 subculture displayed positive fluorescence when incubated with A...

BACKGROUND: Haemonchus contortus is known among parasitic nematodes as one of the major veterinary pathogens of small ruminants and results in great economic losses worldwide. Human activities, such as the sympatric grazing of wild with domestic animals, may place susceptible wildlife hosts at risk of increased prevalence and infection intensity with this common small ruminant parasite. Studies on phylogenetic factors of H. contortus should assist in defining the amount of the impact of anthropogenic factors on the extent of sharing of agents such as this nematode between domestic animals and wildlife...

Breeding towards genetic resistance to prion disease is effective in eliminating scrapie. In sheep, classical forms of scrapie have been eradicated almost completely in several countries by breeding programs using a prion protein (PrP) gene (PRNP) amino acid polymorphism. For goats, field and experimental studies have provided evidence for several amino acid polymorphisms that are associated with resistance to scrapie, but only limited data are available concerning the susceptibility of caprine PRNP genotypes to BSE...

BACKGROUND: Understanding which factors drive population densities of disease vectors is an important step in assessing disease risk. We tested the hypothesis that the density of ticks from the Ixodes ricinus complex, which are important vectors for tick-borne diseases, is determined by the density of deer, as adults of these ticks mainly feed on deer. METHODS: We performed a cross-sectional study to investigate I. ricinus density across 20 forest plots in the Netherlands that ranged widely in deer availability to ticks, and performed a deer-exclosure experiment in four pairs of 1 ha forest plots in a separate site...

BACKGROUND: Bartonellosis is an emerging vector-borne disease caused by different intracellular bacteria of the genus Bartonella (Rhizobiales: Bartonellaceae) that is transmitted primarily by blood-sucking arthropods such as sandflies, ticks and fleas. In Tunisia, there are no data available identifying the vectors of Bartonella spp. In our research, we used molecular methods to detect and characterize Bartonella species circulating in fleas collected from domestic animals in several of the country's bioclimatic areas...

Schmallenberg virus (SBV) was first detected in 2011 in Germany and then in France in 2012. This study simulates the production of different ruminant systems in France and estimates, through partial budget analyses, the economic cost of SBV at the farm level, under two disease scenarios (a high-impact and low-impact scenario). A partial budget is used to evaluate the financial effect of incremental changes, and includes only resources or production that will be changed. In the high-impact scenario, the estimated impact of SBV ranged from €23 to €43 per cow per year and €19 to €37 per ewe per year...

BACKGROUND: Hypoxic-ischemic encephalopathy (HIE) is an important cause of neonatal mortality and neurological morbidity, even despite hypothermia treatment. Neuronal damage in these infants is partly caused by the production of superoxides via the xanthine-oxidase pathway and concomitant free radical formation. Allopurinol is a xanthine-oxidase inhibitor and can potentially reduce the formation of these superoxides that lead to brain damage in HIE. METHODS: The aim of this review is to provide an overview of the animal and clinical data about the neuroprotective effect of allopurinol in HIE and the relevant mechanisms leading to brain injury in HIE...

Tissue-engineered (TE) grafts based on decellularized grafts have shown very promising results in preclinical and clinical studies. However, in animal models valves have either been tested in juvenile models or in the clinically less relevant pulmonary valve position. In this study, we tested the grafts in the aortic valve (AV) position of 6-year old sheep, as geriatric patients in need of an aortic valve substitute due to calcification are the largest patient group benefiting from TE grafts. Decellularized AV (n=4) and decellularized AV additionally re-endothelialized with autologous cells (n=3) were implanted in the aortic valve position of 6-year-old female sheep...

Tay-Sachs disease (TSD) is a fatal neurodegenerative disorder caused by a deficiency of the enzyme hexosaminidase A (HexA). Tay-Sachs disease also occurs in sheep, the only experimental model of TSD that has clinical signs of disease. The natural history of sheep TSD was characterized using serial neurological evaluations, 7 tesla MRI, echocardiograms, electrodiagnostics and cerebrospinal fluid (CSF) biomarkers. Intracranial gene therapy was also tested using AAVrh8 monocistronic vectors encoding the α subunit of Hex (TSD α) or a mixture of two vectors encoding both the α and β subunits separately (TSD α+β) injected at high (1...
