| 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. | 1973 | 4582640 |
| 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. | 1972 | 4629262 |

| genomic alterations associated with persistent infections by equine infectious anaemia virus, a retrovirus. | the unique periodic nature of equine infectious anaemia (eia) is believed to result from the ability of the infecting virus. eiav, to undergo relatively rapid antigenic variations which circumvent host immune responses resulting in distinct virus populations in sequential clinical episodes in the persistently infected horse. this model was examined by oligonucleotide mapping comparisons of the rna genomes of selected isolates of eiav. variations in oligonucleotide maps could be reproducibly demo ... | 1984 | 6086822 |
| enzyme-linked immunosorbent assay for detection of equine infectious anemia antibody to purified p26 viral protein. | an indirect enzyme-linked immunosorbent assay (elisa) was developed for the detection of equine infectious anemia (eia) antibody in horse sera. purified p26 viral protein was the antigen; alkaline phosphatase linked to rabbit anti-horse immunoglobulin g was the conjugate. the elisa detected eia antibodies in horse sera as early as 11 to 14 days after experimental inoculations. there was full agreement between the results of elisa and the agar-gel immunodiffusion tests on eia proficiency test ser ... | 1984 | 6089620 |

| hemagglutination-inhibition tests with different strains of equine infectious anemia virus. | the serologic relationships between 6 strains of equine infectious anemia (eia) viruses were investigated by hemagglutination-inhibition (hi) tests. cross hi tests, using sera from horses in the early stage of infection, revealed that all strains were inhibited only by homologous strain antisera and that hi antibody was always detectable before virus-neutralizing antibody. in the later stages of infection, both homologous and heterologous hi antibodies were detected in a sera of most of the hors ... | 1981 | 6175255 |
| in vitro host range of equine infectious anemia virus. | equine infectious anemia virus (eiav) was successfully inoculated onto cell cultures of canine and feline origin, resulting in chronic infections in these cultures. infection of equine cell cultures, which were the previous sole in vitro source demonstrated for virus production, was also performed for comparative purposes. determination of the nature of the virus produced in the heterologous as well as the equine cells was accomplished in several ways. sds-page of purified virus from the differe ... | 1981 | 6177659 |
| isolation and comparative biochemical properties of the major internal polypeptides of equine infectious anemia virus. | we describe procedures for the large-scale production of equine infectious anemia virus (eiav) and for the isolation of the four major non-glycosylated virion proteins, designated p26, p15, p11, and p9. comparisons of the purified proteins by peptide mapping procedures and by enzyme-linked immunosorbent assays demonstrated the unrelatedness of the four proteins. the characteristic properties of each purified protein were examined by determining isoelectric points and amino acid compositions. we ... | 1982 | 6178843 |
| antigenic reactivity of the major glycoprotein of equine infectious anemia virus, a retrovirus. | the immunogenic contributions of the carbohydrate and peptide portions of the major envelope glycoprotein of equine infections anemia virus, eiav gp90, were analyzed by measuring the effects of specific glycosidase and protease digestions on the reactivity of the glycoprotein with immune sera from infected horses. the results of both direct and competitive radioimmunoassay demonstrated that immune sera contained antibodies reactive with both the carbohydrate and protein moieties of eiav gp90, wi ... | 1984 | 6205503 |
| antigenic variation during persistent infection by equine infectious anemia virus, a retrovirus. | the recurrent nature of equine infectious anemia has been attributed to relatively rapid antigenic variations in equine infectious anemia virus (eiav) during persistent infection under selective immune pressures. this model was tested by serological and biochemical analysis of virus isolates recovered from separate febrile episodes in two experimentally infected ponies. neutralization assays employing immune sera from the experimentally infected ponies demonstrated that distinct antigenic strain ... | 1984 | 6206055 |

| transmission of equine infectious anemia virus from horses without clinical signs of disease. | twenty seven adult horses positive to the agar gel immunodiffusion (agid) test for equine infectious anemia (eia), but with no history of clinical eia, were used in transfusion studies to determine whether infectious eia virus was present in 1 to 5 ml of their blood. of 27 recipients, 21 (78%) became agid test-positive at an average of 24 days after inoculation. two horses that were initially negative when screened were retested and found to carry infectious virus in 5-300 ml of whole blood; the ... | 1982 | 6276353 |
| detection of equine infectious anemia virus in a horse with an equivocal agar gel immunodiffusion test reaction. | a horse whose serum reacted equivocally in the agar gel immunodiffusion (agid) test for equine infectious anemia was studied over a 3-year period. the horse remained afebrile and virus was detected in only 1 of 6 horse inoculation tests. the intensity of agid test reactions increased temporarily following this evidence for virus. although the agid test reaction was equivocal and 5 of the 6 transmission attempts failed, the 1 successful transmission proved the horse was infected. | 1982 | 6276354 |
| indirect hemagglutination test in equine infectious anemia. | an indirect hemagglutination was developed for the diagnosis of equine infectious anemia using sheep red blood cells coated with group specific virus antigen which had been highly purified by affinity chromatography. the presence of indirect hemagglutination antibodies was demonstrated in horses with equine infectious anemia since the cells were specifically agglutinated by all the serum samples obtained from experimentally infected horses. antibodies appeared within 35 days after inoculation, a ... | 1982 | 6280821 |
| antigenic stimulation of t lymphocytes in chronic nononcogenic retrovirus infection: equine infectious anemia. | equine infectious anemia is a chronic disease of horses caused by a nononcogenic retrovirus. studies were undertaken to determine the types of cells involved in the in vitro lymphoproliferative response to viral antigens and the dynamics of this reaction. it was observed that reactive lymphocytes were present at unpredictable times in the peripheral blood of infected horses. this reaction was shown to be specific for the interaction of equine infectious anemia virus and t lymphocytes. enriched b ... | 1982 | 6281191 |

| dna sequence relationship of the baboon endogenous virus genome to the genomes of other type c and type d retroviruses. | baboon endogenous virus (baev) is a type c retrovirus present in multiple proviral copies in the dna of baboons. although interspecies antigenic determinants present on reverse transcriptase and gag proteins are shared among all mammalian type c viruses, no nucleic acid homology between baev and other type c viruses (except rd-114) has been found in conventional liquid hybridization experiments. in this study, we used restriction fragments of cloned baev dna immobilized on nitrocellulose to test ... | 1982 | 6284972 |
| virulence and in vitro growth of a cell-adapted strain of equine infectious anemia virus after serial passage in ponies. | five serial passages of a cell-adapted strain of equine infectious anemia (eia) virus were conducted in shetland ponies. the 13 recipient ponies became agar-gel immunodiffusion test-positive by 25 days after they were inoculated. the virulence of the cell-adapted strain of eia virus markedly increased through 3 serial passages, although individual variation within passages was high. the 1st serial-passage recipient remained afebrile through 200 days, whereas a febrile episode occurred about ever ... | 1982 | 6293349 |
| equine infectious anaemia: detection of antibodies using an immunofluorescence test. | an indirect immunofluorescence test for detecting antibodies to equine infectious anaemia virus is presented. using monolayers of equine dermal cells within a defined period after infection, discrete fluorescent spots were observed in the cytoplasm of as many as 95 per cent of the cells. these inclusions appeared as ring-like structures when high titred sera were employed but became spots when the sera were diluted. cells showing optimal antigen fluorescence were used immediately or after storag ... | 1982 | 6296954 |

| studies on equine infectious anemia virus transmission by insects. | there are several factors involved in the mechanical transmission of equine infectious anemia (eia) virus by insects. large hematophagous insects, especially tabanids, which feed from extravascular sites (ie, pool feeding) appear to be the most efficient vectors. the biology of the host-seeking and blood-feeding behavior of the vectors are important variables that have been overlooked in the mechanical transmission of pathogens like eia virus. the biology, population levels, and diversity of the ... | 1984 | 6321420 |
| detection of equine infectious anemia virus in horse leukocyte cultures derived from horses in various stages of equine infectious anemia viral infection. | the enzyme-linked immunosorbent assay (elisa) antigen-positive and agar-gel immunodiffusion test (agid)-negative horses do not have infective equine infectious anemia (eia) virus. the elisa testing of horse leukocyte culture (hlc) supernatants did detect eia virus in a hlc that was infected with the wyoming strain of eia virus and in hlc derived from horses in febrile, acute, or subacute stages of eia infection. in supernatants of hlc derived from chronic and inapparent carrier horses, eia virus ... | 1984 | 6322623 |
| structural proteins of equine infectious anemia virus and their antigenic activity. | using purified equine infectious anemia (eia) virus labeled with 3h-glucosamine or 14c-protein hydrolysate, structural proteins were analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. as a result, 2 glycoproteins and 10 proteins with molecular weights (mol wt) ranging from 12,000 to 115,000 daltons were demonstrated. of 12 structural proteins, 3 proteins, namely a glycoprotein with mol wt of 76,000 (gp76) and 2 proteins with mol wt of 25,000 (p25) and 12,000 (p12), respective ... | 1984 | 6322625 |
| cytoplasmic inclusions in cells infected with the virus of equine infectious anemia (eiav). | after infection with equine infectious anemia virus (eiav) equine dermal (ed) cells revealed fluorescent spots in their cytoplasm which were detected with an indirect immunofluorescence technique. to characterize the nature of these cytoplasmic inclusions, comparative light and electron microscopic studies were performed. the cytoplasmic location of the spots observed in the indirect immunofluorescence assay coincided with the location of structures detected with the electron microscope. in ultr ... | 1984 | 6325195 |
| enzyme-linked immunosorbent assay for detection of equine infectious anemia virus p26 antigen and antibody. | a sensitive specific enzyme-linked immunosorbent assay utilizing purified p26 antigen was developed for the detection of antibodies to equine infectious anemia virus in naturally and experimentally infected horses. generally, antibodies to the virus could be detected by the enzyme-linked immunosorbent assay 3 to 4 days earlier than by the standard agar gel immunodiffusion test, and they could be detected more reliably in horses with weak or equivocal agar gel immunodiffusion test reactions. the ... | 1984 | 6325488 |
| characterization of monoclonal antibodies directed against the envelope proteins of feline leukemia virus. | monoclonal antibodies directed against the feline leukemia virus (felv) envelope proteins, gp70 and p15e, were identified by radioimmunoprecipitation and sodium dodecyl sulfate-polyacrylamide gel electrophoresis. six of these monoclonal antibodies were specific for the gp70; two for the p15e. enzyme-linked immunosorbent assay binding assays against felv subtypes a, b, and c showed that most of the monoclonal antibodies bound to more than one subtype but have a greater affinity for subtype b. one ... | 1984 | 6331649 |
| carriers of equine infectious anemia virus. | presently available data continue to support the idea that once a horse is infected with equine infectious anemia virus it remains infected indefinitely. infection may not always be demonstrated by inoculation of plasma, serum, or whole blood transfusions into susceptible recipients, but transfusions of fresh whole blood will be infective in at least 95% of the horses testing positive in the agar gel immunodiffusion test. for detection of infectivity in a small percentage of inapparent carriers, ... | 1984 | 6421787 |
| effects of common radioiodination procedures on the binding of glycoproteins to immobilized lectins. | representative glycoproteins including fetuin, protein a, ovalbumin, alpha 1 acid glycoprotein, and the major glycoprotein of equine infectious anemia virus were labelled with 125i by the chloramine-t or bolton-hunter procedure and their binding to immobilized con a or lentil lectin compared to untreated samples of each glycoprotein. glycoprotein modification was no greater than one substituted residue per protein molecule. yet the radioiodinated glycoproteins typically displayed only 0-50% of t ... | 1983 | 6838504 |
| nmr analysis of the trans-activation response (tar) rna element of equine infectious anemia virus. | transcription of lentiviral dna in the host cell is regulated by an interaction between the viral tar rna stem-loop and the viral tat protein. here we present a model of the three-dimensional structure of the tar rna stem-loop of the equine infectious anemia virus (eiav), derived from two- and three-dimensional nmr data. this 25 nucleotide rna consists of an a-form helical stem capped by two u-g base pairs and a four-nucleotide loop. two loop cytidines are stacked into the loop interior and like ... | 1995 | 7479065 |
| equine infectious anemia virus tat is a predominantly helical protein. | nuclear magnetic resonance (nmr) spectroscopy revealed features of the secondary structure of the equine infectious anemia virus (eiav) tat protein in solution. we could show that this protein, which is required in the replication cycle of lentiviruses, forms a predominantly helical structure in trifluoroethanol/water (40% by vol.) solution. in particular, the basic rna-binding region and the adjacent core domain, which are highly conserved among lentiviral tat proteins, show helix-type secondar ... | 1993 | 7506657 |
| the catalytic properties of the reverse transcriptase of the lentivirus equine infectious anemia virus. | the reverse transcriptase (rt) of equine infectious anemia virus (eiav) shares sequence similarity with the rts of other lentiviruses, particularly with the rts of human immunodeficiency viruses types 1 and 2 (hiv-1 and hiv-2, respectively), the causative agents of acquired immunodeficiency syndrome (aids). there is a 41-42% sequence identity between eiav rt and both hiv rts (which have 61% sequence identity to each other). we have compared the enzymic properties of eiav rt with those of hiv-1 r ... | 1994 | 7509281 |
