A non-haemagglutinating isolate of mink enteritis virus.

ABSTRACT

A virus was isolated from mink showing clinical and pathological signs of mink enteritis. This virus was identified as mink enteritis virus (MEV) from results of serological tests, determination of its density in CsCl (1.415 g cm-3), and morphology, including size (20 nm in diameter). The isolate was designated MEV-S. In contrast to other known MEV strains, the MEV-S isolate has no haemagglutinating (HA) activity with swine red blood cells (RBCs) at 4 degrees C and pH 6.8. Neither was there any HA at other pH values and temperatures, or when horse, bovine and rhesus monkey RBC's were used.
