Three newborn, colostrum deprived calves were inoculated by the intranasal, intratracheal, conjunctival and oral routes with a subgroup II bovine adenovirus strain 7T. An initial viremia and febrile response occurred in all calves with widespread dissemination of the virus through the body. Clinical signs consisted of pyrexia, soft feces and...
Using the Matsubara Green's function technique we calculate the
infrared polariton dispersion relation from the lowest order terms of
a Hamiltonian which includes radiation fields and electron effects.
The formalism allows generation of higher order interaction terms,
one of which contains the Frohlich conduction electron optical phonon
interaction. By comparing...
The occurrence and distribution of fish viruses in Oregon were
determined by the examination of anadromous and fresh water salmonids.
Infectious pancreatic necrosis virus (IPNV) was isolated and
identified from asymptomatic adult coho (Oncorhynchus kisutch) and
chinook (0. tshawytscha) salmon returning to the Columbia River
system. Infectious pancreatic necrosis virus...
The research presented in this thesis is concerned
with the
characterization of two salmonid cell lines, CSE 119 derived
from
embryos of coho salmon (Oncorhynchus kisutch) and
STE 137 derived
from embryos of steelhead trout (Salmo gairdneri).
The rates of
glucose utilization and lactic acid production during the most
active...
The Oregon strain of the agent of infectious hematopoietic necrosis (IHN) was isolated from fingerling sockeye salmon (Oncorhynchus nerka) by J. L. Fryer in 1958. Before the study reported herein no other virus had been recovered from any fish population in Oregon. Therefore, in July, 1971 a survey was initiated...
