Barrier-bred cats were inoculated intracerebrally with either the rabbit-adapted Borna disease virus (BDV) strain V or a newly isolated feline BDV, obtained from a cat with natural staggering disease (SD). Three out of eight inoculated cats developed neurological signs and non-suppurative encephalitis; all three recovered from the acute stage of disease.(More)
The uptake and distribution of zinc in tissues and the effects of 2500 ppm dietary zinc oxide on health, faecal microflora, and the functions of circulating neutrophils were evaluated in weaned pigs. One group was fed a zinc supplement diet and another group was used as a control. All pigs remained healthy throughout the study, but the supplemented animals(More)
This field study explored the cytokine expression in intestinal tissue and serum from 19 diarrhoeic and 9 healthy pigs in herds with a long-time history of Lawsonia intracellularis-infection. The disease, proliferative enteropathy (PE), is associated with diarrhoea and poor performance in growers and haemorrhagic diarrhoea and sudden death in finisher pigs,(More)
Mast cells of a number of different animal species have been reported to contain serotonin (5-hydroxytryptamine; 5-HT), a monoamine capable of numerous and complex actions, which may include an impact on tumour growth. Limited previous studies have suggested that normal or neoplastic canine mast cells do not express 5-HT. In the present study, canine(More)
The quantitative swab culture is a reliable method for quantifying the number of viable bacteria colonizing open wounds. For open wounds in burn patients, the swab bacterial count is linearly related to biopsy quantification of viable bacteria in the underlying tissue. This technique is simple and requires no surgical manipulation of the wound. For a wound(More)
Eight horses (mean weight 438 kg) with chronic obstructive pulmonary disease (COPD) were studied for clinical signs, ventilation/perfusion relationships (VA/Q) and lung morphology. Four horses were killed and necropsied after the study. In horses with COPD, minute ventilation was almost twice as high as normal, whereas PaO2 was significantly decreased.(More)
