Glycogen Branching Enzyme Deficiency (GBED), a fatal condition recently identified in fetuses and neonatal foals of the Quarter Horse and Paint Horse lineages, is caused by a nonsense mutation in codon 34 of the GBE1 gene, which prevents the synthesis of a functional GBE protein and severely disrupts glycogen metabolism. The aims of this project were to… (More)
A diagnosis of beta-mannosidosis, a lysosomal storage disease caused by a deficiency of beta-mannosidase, was made in 12 purebred Salers calves. Affected neonatal calves were unable to rise and had intention tremors, hidebound skin, slightly domed calvaria, slight prognathism, and narrow palpebral fissures. Postmortem findings included variable dilatation… (More)
Toxoplasma gondii infection was diagnosed in a full term stillborn reindeer (Rangifer tarandus) fetus. The fetus had encephalitis and placentitis associated with T. gondii. Tissue cysts were identified histologically in sections of brain and tachyzoites were present in placenta and the myocardium. Protozoa in the brain, heart, and placenta stained… (More)
In bovine beta-mannosidosis, the thyroid in the affected newborn shows marked cytoplasmic vacuolation. There is an associated reduction in the serum concentrations of thyroxine and tri-iodothyronine.
In bovine β-mannosidosis, the thyroid in the affected newborn shows marked cytoplasmic vacuolation. There is an associated reduction in the serum concentrations of thyroxine and tri-iodothyronine.
This paper describes Neospora caninum-associated hydrocephalus in an aborted Hereford bovine fetus of 7 months' gestational age. Numerous tachyzoites were observed in areas of the cerebrum with lesions of non-suppurative necrotizing encephalitis.
Plasma beta-mannosidase activities were determined for Salers cattle from 8 herds as an evaluation of this method for detection of beta-mannosidosis heterozygotes. Several biological factors, such as age, gender, herd, and risk of being a beta-mannosidosis carrier, were considered in this study. The mean enzyme activity for obligate heterozygotes (n = 8)… (More)
