Control of parasitic bronchitis and gastroenteritis in grazing cattle by strategic prophylaxis with ivermectin     

J Armour  K Bairden  H M Pirie  W G Ryan 《The Veterinary record》1987,121(1):5-8

In May 1985 four groups of 10 calves, aged between four and five months, were turned out on to separate, permanent pastures of equal area which had been seeded during the previous few days with larvae of Dictyocaulus viviparus. One group acted as a control, the second was vaccinated with lungworm vaccine before turnout and treated with thiabendazole three, eight and 13 weeks after turnout, while the third and fourth groups were given ivermectin three times (three, eight and 13 weeks after turnout) and twice (three and eight weeks after turnout), respectively. A severe outbreak of parasitic bronchitis resulted in the death of three control calves within five weeks of turnout and parasitic bronchitis and gastroenteritis affected the second group of calves after approximately four months at pasture. The calves given ivermectin excreted no lungworm larvae and remained free of clinical parasitism throughout the trial.  相似文献

Melanotic neuro-ectodermal tumour of infancy (melanotic progonoma) in two calves.     

A Wiseman  R G Breeze  H M Pirie 《The Veterinary record》1977,101(13):264-266

Large unilateral tumours involving the mandible in two calves were composed of melanin-containing cells and small lymphocyte-like cells in a cellular fibrous stroma. These neoplasms resembled the melanotic neuro-ectodermal tumour of infancy.  相似文献   

Morphological, Histochemical and Ultrastructural Features of the Globule Leukocyte of the Bovine Respiratory Tract     

S. O. Akpavie  H. M. Pirie 《Anatomia, histologia, embryologia》1990,19(2):164-180

The histochemical and ultrastructural features of the globular leukocyte of the bovine respiratory tract is described and found to be similar to those localized in the abomasum and bile ducts of cattle. Histochemical analysis of these cells demonstrated low amounts of carboxylated mucin mixed with neutral mucin and large amounts of basic protein. Two types of globules were seen in the leucocytes; one with a homegeneous electron dense material and another with vesiculated, crastalloid containing bodies.  相似文献   

Utilizing a combination of molecular and spatial tools to assess the effect of a public health intervention

Until recently New Zealand had one of the highest rates of human campylobacteriosis reported by industrialized countries. Since the introduction of a range of control measures in the poultry production chain a reduction in human cases of around 50% has been observed nationwide. To inform risk managers a combination of spatial, temporal and molecular tools - including minimum spanning trees, risk surfaces, rarefaction analysis and dynamic source attribution modelling - was used in this study to formally evaluate the reduction in disease risk that occurred after the implementation of control measures in the poultry industry. Utilizing data from a sentinel surveillance site in the Manawatu region of New Zealand, our analyses demonstrated a reduction in disease risk attributable to a reduction in the number of poultry-associated campylobacteriosis cases. Before the implementation of interventions poultry-associated cases were more prevalent in urban than rural areas, whereas for ruminant-associated cases the reverse was evident. In addition to the overall reduction in prevalence, this study also showed a stronger intervention effect in urban areas where poultry sources were more dominant. Overall a combination of molecular and spatial tools has provided evidence that the interventions aimed at reducing Campylobacter contamination of poultry were successful in reducing poultry-associated disease and this will inform the development of future control strategies.  相似文献   

Scleral and suprachoroidal foreign body in a dog--a case report     

Welihozkiy A  Pirie CG  Pizzirani S 《Veterinary ophthalmology》2011,14(5):345-351

A 2-year-old male castrated Springer Spaniel with a 3-week history of waxing and waning right sided exophthalmos, periorbital swelling, chemosis, and fundic changes was examined. Ophthalmic examination of the right eye revealed slight chemosis and nictitating membrane protrusion. Indirect ophthalmoscopy showed an approximately 8 mm peripapillary hyporeflective tapetal lesion with subretinal edema consistent with a bulbar/retrobulbar disease process. Inflammatory or neoplastic diseases were the main differential diagnoses. Ancillary diagnostics (ocular ultrasound and computed tomography) showed a focal, poorly defined dense tissue involving the caudomedial aspect of the right globe, adjacent to the optic nerve head without apparent orbital involvement. Considering the duration, location, and severity of the clinical findings, enucleation of the right globe was performed. Histopathology revealed focal thickening of the posterior wall with severe pyogranulomatous inflammation, surrounding a foreign body most consistent with plant material embedded between the sclera and the choroid (suprachoroidal). This report describes a rare case of a scleral/suprachoroidal foreign body (plant material), and outlines the difficulty of establishing an etiological diagnosis using standard ocular imaging.  相似文献   

360-degree conjunctival grafting for management of diffuse keratomalacia in a dog     

Pumphrey SA  Pizzirani S  Pirie CG 《Veterinary ophthalmology》2011,14(3):209-213

We present a report describing use of a 360-degree conjunctival graft for management of progressive keratomalacia refractory to medical treatment in a 5-month-old American Cocker Spaniel. In the dog of this report, the extension of melting to nearly the entire corneal surface limited surgical options. Following surgery and later resection of the graft, the patient is visual with minimal corneal opacity. Numerous corneal grafting techniques have been described in companion animals, but require special materials and may not be possible when melting is extensive. Although older animals or animals with additional corneal pathology may have less ideal outcomes in terms of corneal clarity than the patient of this report, we believe that 360-degree conjunctival grafting offers a viable and cost-effective option for management of cases with extensive keratomalacia that may otherwise have resulted in enucleation.  相似文献
