Intramedullary Intervertebral Disk Extrusion in a Cat     

J. Fraser McConnell BVM&S    Laurent S. Garosi DVM 《Veterinary radiology & ultrasound》2004,45(4):327-330

Intervertebral disk extrusion is rarely reported in the cat. In this case, the clinical, radiologic, and magnetic resonance imaging findings of an acute intramedullary intervertebral disk extrusion in a 5-year-old domestic shorthaired cat are described. Radiographically, there was mineralized disk material within the vertebral canal. On magnetic resonance images, the disk material was found to be within the spinal cord. A linear disk trail extending from the disk space into the spinal cord may be specific for intramedullary disk extrusion.  相似文献   

Molecular epidemiology of two fowl cholera outbreaks on a free-range chicken layer farm.

Two outbreaks of fowl cholera on a multiage free-range egg farm were investigated. The outbreaks occurred in 1994 and 2002. A total of 22 strains of Pasteurella multocida were available for study, 11 from the 1994 outbreak and 11 from the 2002 outbreak. Lesions typical of acute fowl cholera were seen in the 1994 outbreak, whereas both acute and chronic fowl cholera occurred in the 2002 outbreak. The isolates were examined in an extended phenotypic typing methodology, by a P. multocida-specific polymerase chain reaction (PCR), by the Heddleston somatic serotyping scheme, and by restriction endonuclease analysis (REA) typing using the enzyme HpaII. All 22 strains had the same phenotypic properties, all were confirmed as P. multocida by PCR, all were Heddleston serovar 4, and all had the same REA pattern. The results indicate that these 2 outbreaks were caused by the same clone of P. multocida--despite the 8-year time period between the outbreaks.  相似文献

Infection of human enterovirus 71 in immunosuppressed rhesus monkeys

AIM: To investigate the infection process of human enterovirus 71 (EV71) in a rhesus monkey model of immunosuppression.METHODS: The monkey immunosuppression model was established by oral administration of cyclosporin A at a daily dose of 15 mg/kg for 7 days. Fourteen days after inoculation of EV71 FY23 strain via respiratory and digestive tracts, the infectious monkeys were sacrificed, and then the pathological changes of systemic organs were observed and the viral analysis in different tissues was performed.RESULTS: Compared with the experimental group without cyclosporin A, more positive results were observed in the immunosuppressed monkeys, such as more severe clinical symptoms, higher viral load/antigen expression and more pathological changes in the organs.CONCLUSION: The findings of the viral multiplication in the host provide evidence for evaluation of EV71 vaccine, and also indicate the delimitation for the population using EV71 vaccine in future.  相似文献
