Plaquing procedure for infectious hematopoietic necrosis virus.
A single overlay plaque assay was designed and evaluated for infectious hematopoietic necrosis virus. Epithelioma papillosum carpio cells were grown in normal atmosphere with tris(hydroxymethyl)aminomethane- or HEPES (N-2-hydroxyethylpiperazine-N'-2-ethanesulfonic acid)-buffered media. Plaques were larger and formed more quickly on 1- to 3-day-old cell monolayers than on older monolayers. Cell ...
متن کاملBiophysical studies of infectious pancreatic necrosis virus.
The molecular weight of infectious pancreatic necrosis virus (IPNV) has been determined by analytical ultracentrifugation and dynamic light scattering. The sedimentation coefficient of the virus was found to be 435S. The average value for molecular weight is (55 +/- 7) x 106. The virus genome consists of two segments of double-stranded RNA (molecular weights, 2.5 x 106 and 2.3 x 106), which rep...
متن کاملAquareovirus interference mediated resistance to infectious hematopoietic necrosis virus.
This study investigated the stimulation of specific host defenses to IHNV that are created by prior exposure to an avirulent reovirus (chum salmon reovirus; CSV). Preexposure of rainbow trout to CSV for 1 h resulted in a relative percent survival that ranged from 68 to 100% when fish were challenged with IHNV over an 8 week period. The levels of serum neutralizing antibodies detected 28 d after...
متن کاملThermal inactivation of infectious hematopoietic necrosis and infectious pancreatic necrosis viruses.
A plaque assay was used to follow the inactivation kinetics of infectious hematopoietic necrosis virus and infectious pancreatic necrosis virus in cell culture media at various temperatures. Inactivation of infectious hematopoietic necrosis virus in a visceral organ slurry was compared with that in culture media.
متن کاملPhysico-chemical and morphological features of infectious pancreatic necrosis virus.
Infectious pancreatic necrosis (IPN) virus has been purified and some physicochemical properties of its nucleic acid and protein moieties have been determined. The buoyant density of the virus particle in CsC1 is 1.35 g/ml; degraded particle banded at a density of 1.31 g/ml. The virus nucleic acid was found to be doublestranded, according to several different criteria, namely resistance to panc...
