Cytopathic and noncytopathic
WebBiotypes (cytopathic vs. noncytopathic) are defined on the basis of cytopathic effects in cultured epithelial cells. However, virulence phenotype in vivo correlates with the noncytopathic rather than the cytopathic biotype. The authentic form of BDV is predominantly an ovine pathogen, although pigs are also affected. WebAbstract A panel of monoclonal antibodies that recognize the two major glycoproteins of bovine viral diarrhea virus (BDV) was used to evaluate the antigenic relationship between cytopathic (CP) and noncytopathic (NCP) viruses isolated from cattle dead or dying from fatal BDV infections.

WebThe two biotypes of BVDV, cytopathic and noncytopathic, have separate biologic roles2; biotype differences are important in disease pathogenesis. Both biotypes of BVDV infect cattle and cause disease, but only the noncytopathic isolates cause persistent infections.
Webcytopathic effects in cultured cells and noncytopathic viruses (ncpBVDV) that do not cause cytopathic effects in cultured cells (7–10). It was previously reported that a number of cell lines (e.g., cattle, sheep, goat, deer, bison, rabbit, and domestic cat origins), including the RK-13 cell line (CCL-37; American Type Culture WebTwo biotypes of BVDV, cytopathic and noncytopathic, occur in nature. The viral biotypes are identified by cytopathic effect in susceptible cell cultures. Cytopathic BVDV induces cytoplasmic vacuolation, cell …

WebJun 25, 2016 · The biotype, cytopathic (CP) or noncytopathic (NCP), was determined by cell culture virus isolation. Twenty-eight of 103 samples were submitted for herd screening for BVDV, 32 from OADDL necropsy cases, and 43 from live cattle with varied clinical conditions. Two samples contained 2 bands indicating presence of both BVDV types 1 …
