Rabies was diagnosed in a 40 kg pig from a closed feeder barn in which recently unexplained deaths of eight to ten pigs had occurred. A stray cat, probably crawling through a ventilation duct into the barn, was the suspected vector. Over a four and one-quarter year period a disproportionate 53 cases of animal rabies had been diagnosed within a 5 km radius of the farm (13% of the cases in the county in 3% of the county area). Histological lesions, mostly lymphocytic cuffing of blood vessels in the brain with lymphocytic meningitis, patchy to focal gliosis and satellitosis with neuronal necrosis were nonspecific and Negri bodies were rare. Fluorescent antibody technique examination of the brain for rabies virus antigen was positive.  相似文献

The purpose of this paper is to emphasize the importance of pulmonary auscultation for the clinician. It suggests a clarification and simplification of the terminology to be used which would be helpful to veterinary students and allow better communications between veterinarians. The interpretation of these sounds and the relationships to conditions and diseases of the lungs in cattle, horses, sheep and goats are discussed.  相似文献

The tunneling microscope: a new look at the atomic world     

Golovchenko JA 《Science (New York, N.Y.)》1986,232(4746):48-53

A new instrument called the tunneling microscope has recently been developed that is capable of generating real-space images of surfaces showing atomic structure. These images offer a new view of matter on an atomic scale. The current capabilities and limitations and the physics involved in the technique are discussed along with specific results from a study of silicon crystal surfaces.  相似文献
