Abstract

The invention discloses a sensitive cell line SLAM-MDCK of a canine distemper virus and a construction method and application of the sensitive cell line SLAM-MDCK. A canine signaling lymphocytic activation molecule (SLAM) is constructed into an MDCK cell through a retroviral vector, and as a result the cell line SLAM-MDCK capable of stably expressing a canine SLAM gene is constructed. After being infected by the canine distemper virus, the cell line SLAM-MDCK is quick in lesion and high in viral titer, thereby being suitable for separation and culture of the canine distemper virus. Thus, the cell line SLAM-MDCK is of important significance to separation of the canine distemper virus, definite diagnosis of canine distemper virus infection as well as research, development and production of vaccines for the canine distemper virus.

Description

technical field [0001] The present invention relates to the field of cell lines, in particular to a canine distemper virus-sensitive cell line SLAM-MDCK and its construction method and application. Background technique [0002] Canine distemper (CD) is an acute, febrile and highly contagious infectious disease caused by Canine distemper virus (CDV) of the genus Measles virus in the Paramyxoviridae family. The main clinical features are bipolar fever, mucosal inflammation in the eyes, nose, and digestive tract, as well as catarrhal pneumonia, dermatitis, and neurological symptoms. Since it was first reported in 1809, the disease has shown a worldwide epidemic, with severe effects on companion and wildlife. CDV is divided into six different types: Asia-I, Asia-II, Europe, America-II, Arctic and Vaccine. genotype, but only one serotype is recognized. [0003] The natural infection hosts of CDV are very extensive and show an ever-expanding trend. It has been expanded from th...
