Interspecies virus transmission

摘要

Interspecies virus transmission between dogs and cats has been known to occur with certain viruses (e.g., canine parvovirus) and suspected to occur with others (e.g., feline calicivirus) for several years. The mechanisms whereby viruses cross over into a secondary viruses acquire multiple-host ranges, their ability to sustain infection in the animal population increases. Increased recognition of unusual clinical signs and enhanced sensitivity of laboratory detection assays have refined the ability to detect emerging infections.
