| Abstract: | A retrospective study was done to correlate serum calcium concentrations and parathyroid gland ultrastructure to clinical, immunologic, and pathologic changes experimentally induced in gnotobiotic dogs by canine distemper virus (CDV). Dogs infected with CDV had significantly reduced serum calcium concentrations associated with ultrastructural evidence of parathyroid gland inactivity, degeneration, and viral inclusions. Although CDV-infected dogs exhibited neurologic signs, minimal lesions were present in the central nervous system. It is suggested that viral-induced parathyroid dysfunction may contribute to neutrologic disturbance of CDV infection. |
