identification of multiple equine infectious anemia antigens by immunodiffusion reactions.equine infectious anemia (eia) cell antigens prepared from infected equine spleen, equine leukocyte cultures or a persistently infected equine dermis cell line contained at least two serologically reacting components. for convenience one component was designated as soluble antigen (sa) and the other as cell-associated antigen (caa). the sa appeared as a single component when it was prepared from eia virus precipitated from infectious tissue culture fluid with polyethylene glycol and ether treate ...1975169969
monocyte activation in horses persistently infected with equine infectious anemia virus.the monocytes of horses infected with equine infectious anemia virus were shown by their failure to migrate from capillary tubes and their increased adherence to erythrocytes to be activated.1975172455
investigation of equine infectious anaemia in queensland using gel diffusion.an antigen for the gel diffusion test for equine infectious anaemia (eia) was prepared from the spleen of a horse experimentally infected with the cq strain of the virus. the antigen produced a single, distinct line of precipitation when tested against a range of known positive serums, and did not react with pre-inoculation and known negative serums. extracts prepared from uninfected spleens displayed no reaction when similarly tested. serum from 34 of 451 queensland horses contained detectable ...1975173275

[purification and study of equine infectious anemia virus antigens, produced in vivo or in cultured cells].the g and c antigens of equine infectious anemia virus have been produced in vivo and in infected cell culture, then they have been purified. their physico-chemical properties have been determined, particularly their molecular weight, their sedimentation coefficient, their density and the iso electric point.1975174831

equine infectious anemia virus from infected horse serum.equine infectious anemia virus was purified from infected horse serum samples. electron microscope observation on negatively stained preparations of purified virus showed roughly spherical particles sized between 100 and 200 nm in diameter. in disrupted particles, an envelope was visible but no internal structure could be resolved. since the purified virus fraction had a strong antigenic activity to antiserum in immunodiffusion reaction, these particles are thought to be the causative virus of e ...19744372175

quantitation of immunoglobulin-bearing lymphocytes and lymphocyte response to mitogens in horses persistently infected by equine infectious anemia virus.a defect in lymphocyte function could be responsible for persistent infection by the equine infectious anemia virus. the number of lymphocytes bearing surface immunoglobulin, as detected by immunofluorescence, and lymphocyte response to mitogens were the same in uninfected and equine infectious anemia-infected animals. a defect in t or b lymphocyte numbers or ability to respond to stimuli was not detected in this chronic virus disease.19734582640
extraction of equine infectious anemia immunodiffusion antigen with the aid of the chaotropic agent, thiocyanate.immunodiffusion antigen from spleens of horses infected with equine infectious anemia virus was prepared by methods employing freeze-thaw cycles and thiocyanate treatment. thiocyanate (0.5 m) permitted the recovery of the greatest amount of antigen. furthermore, it was most effective for recovery of immunodiffusion antigen from spleens which yielded unsatisfactory concentrations of antigen by the conventional freeze-thaw or water-extraction methods. the reactivity of the antigen did not appear t ...19734348466

study of the one-step growth curve of equine infectious anemia virus by immunofluorescence.primary horse leukocyte cultures were inoculated with 2 or 10 50% tissue culture infective doses (tcid(50)) of equine infectious anemia (eia) virus per cell, and the titer of cell-associated and fluid-phase virus was determined from 1 to 72 hr postinoculation (pi). cover slips were collected from 4 to 72 hr pi and stained for eia viral antigen by the indirect immunofluorescent (fa) technique. viral replication was detected after a latent period of approximately 18 to 24 hr and reached peak titer ...19724344094
demonstration of antigenic identity between purified equine infectious anemia virus and an antigen extracted from infected horse spleen.antigenic relationship between purified equine infectious anemia (eia) virus and spleen-derived antigen from eia-infected horses was examined by immunodiffusion. identical antigenicity of these two antigens has been proven because precipitation lines formed between the two antigens and eia antiserum connected with each other. the results indicate that the antigenic substance derived from infected spleen is a component of eia virus.19724629262

electron microscopy of equine infectious anemia virus.equine infectious anemia (eia) virus was observed in thin sections of infected cultured horse leukocytes by electron microscopy. the virus particles had a spherical shape and were between 80 and 120 nm in diameter. most of them contained an electron-dense nucleoid 40 to 60 nm in diameter. they were observed to form by a process of budding from the plasma membrane and appeared to have thin surface projections. the particles described were not detected in uninfected cultured cells, and their appea ...19694311413
