Comparison of three serological tests and an interferon-gamma assay for the diagnosis of paratuberculosis in experimentally infected sheep.
TLDR
The superior performance of the IFN-gamma assay in detecting infected sheep in this small experimental population warrants its further evaluation in a larger population of sheep naturally exposed to M a paratuberculosis. Expand
Vaccination against paratuberculosis of lambs already infected experimentally with Mycobacterium avium subspecies paratuberculosis.
TLDR
The diminished IFN-gamma responses in experimentally infected sheep with acid-fast organisms suggest a positive relationship between the magnitude of the systemic cell-mediated immune response and an animal's ability to control infection. Expand
The potential role of the ovine pharyngeal tonsil in respiratory tract immunity: a scanning and transmission electron microscopy study of its epithelium.
TLDR
Evidence which confirms that the ovine pharyngeal tonsil is part of the respiratory tract-associated lymphoid tissue is provided, by scanning and transmission electron microscopy. Expand
Respiratory tract-associated lymphoid tissue in conventionally raised sheep.
TLDR
The distribution and morphological features of respiratory tract-associated lymphoid tissue was investigated in 20 clinically healthy sheep aged from 6 months to 9 years, and scattered lymphoid cells were the most predominant form. Expand
Mast cells in the bovine lower respiratory tract: morphology, density and distribution.
TLDR
There were significantly more mast cells detected in calf airways fixed with isotonic formal-acetic-acid compared with those seen in the same tissues fixed with neutral buffered formalin. Expand
Dietary antioxidants do not reduce fatty streak formation in the C57BL/6 mouse atherosclerosis model.
TLDR
The results of this study cannot be used to support the hypothesis that antioxidants confer protection against atherosclerosis, but they do raise the possibility that other studies demonstrating an antiatherogenic action of vitamin E and BHT may have been influenced by their effects on lipid metabolism.

Fifty years of leptospirosis research in New Zealand: a perspective
TLDR
It is more likely that most, if not all pathogenic leptospires arrived with intentional and unintentional mammalian imports in the late 18th and 19th centuries. Expand
Use of the polymerase chain reaction assay for the detection of Mycobacterium avium subspecies paratuberculosis in blood and liver biopsies from experimentally infected sheep.
TLDR
The PCR assay on blood and liver biopsies does not provide a useful method for the diagnosis of M a paratuberculosis infection in subclinically infected sheep. Expand
The Pathology of Spontaneously Occurring Malignant Lymphoma in Sheep
TLDR
The most common locations of tumours in 22 sheep with malignant lymphoma were the lymph nodes, spleen, liver, kidneys, kidney, small intestine, heart and heart. Expand
Chondrodystrophy in calves associated with manganese deficiency.
TLDR
A severe congenital chondrodystrophy in Charolais calves is described, with shortened limbs and enlarged joints and a severe reduction in the mucopolysaccharide content of all body hyaline cartilage. Expand
