replication of porcine parvovirus in peripheral blood lymphocytes, monocytes, and peritoneal macrophages.	porcine peripheral blood lymphocytes (pbl), peripheral blood monocytes, and peritoneal macrophages were examined for their ability to support porcine parvovirus (ppv) replication. the cell cultures were infected with the nadl-2 strain of ppv at 0.1 multiplicity of infection. pbl cultures were stimulated with the following phytomitogens: phytohemagglutinin m, concanavalin a, and pokeweed mitogen. unstimulated pbl cultures infected with ppv and uninfected pbl stimulated with phytomitogens served a ...	1979	574124
[verification of the plum pox virus (ppv) using the tray test (author's transl)].	a comparison of 6 host plants reacting by local lesion if infected by the plum pox virus (ppv) demonstrated that beside chenopodium foetidum schrad. also nicandra physaloides (l). gärtner, nicardra physaloides violacea bitter and verbena officinalis l. are pretty well suitable to verify the ppv serving as locally reacting test plants. using the tray test, the ppv was verifiable by separated leaves of c. foetidum schrad., n. physaloides violacea bitter, n. physaloides (l.) gärtner and v. officina ...	1978	664936
serological responses in pigs vaccinated with inactivated porcine parvovirus.	the safety and immunogenicity of inactivated porcine parvovirus (ppv) vaccines were investigated. both beta-propiolactone and formalin successfully inactivated virus without destroying immunogenicity, which was considerably enhanced by incorporation of a gel adjuvant in the vaccine. using the formalised-gel vaccine, initial antibody responses were demonstrated in susceptible piglets and adult pigs at 7 days after vaccination. these antibody responses persist at significant levels for at least 6 ...	1977	565631
reproductive disease experimentally induced by exposing pregnant gilts to porcine parvovirus.	porcine parvovirus (ppv) was administered intravenously or intranasally and orally between the 22nd and the 81st days of gestation to 20 pregnant gilts that were free of hemagglutination-inhibiting (hi) antibody for ppv. gilts were exposed to 1 or both of 2 strains (nadl-7, nadl-2) of ppv and were killed 21 or more days later. fetal and maternal fluids and tissues collected at necropsy were tested for ppv, viral antigen, and hi antibody. transplacental infection occurred with 11 of 12 gilts give ...	1976	999067
pathogenesis of in utero infection: experimental infection of five-week-old porcine fetuses with porcine parvovirus.	injection of porcine parvovirus (ppv) into the allantoic fluid of 3 or 4 fetuses of each of 4 litters of ppv-immune gilts early in gestation (34 to 36 days) resulted in fetal maceration and mummification. a high concentration of virus demonstrated in many tissues of fetuses collected 1 week after initial intraallantoic exposure indicated extensive viral replication. progressively lesser amounts of virus were isolated from tissues of macerated and mummified fetuses collected after longer interval ...	1975	1098529

porcine parvovirus: frequency of naturally occurring transplacental infection and viral contamination of fetal porcine kidney cell cultures.	the frequency of naturally occurring transplacental infection of swine with porcine parvovirus (ppv) and one of the possible consequences of such infection--the presence of ppv in cell cultures prepared from fetal tissues--were investigated. transplacental infection was indicated by the presence of high titers of hemagglutination inhibiting (hi) antibody for ppv in serums of 0-day-old, hysterectomy-derived, colostrum-deprived pigs of 3 of 82 litters. all letters were farm-raised dams. moreover, ...	1975	163603
virus-like particles in buffy coat cells of normal goats and goats infected with progressive pneumonia virus.	by electron microscopy, virus-like particles (vlp) were seen in neutrophils and lymphocytes from buffy coats prepared from 5 goats inoculated with progressive pneumonia virus (ppv) and 3 noninoculated goats. the vlp were 80 to 120 nm in diameter, limited by a unit membrane, and resembled ppv, visna virus, and other members of the oncornavirus family. some vlp seemed to have electron-dense nucleoids and external spikes. in neutrophils, vlp were observed budding into vacuoles; rarely, intravacuola ...	1975	167620
transformation of murine cells by two "slow viruses," visna virus and progressive pneumonia virus.	visna and progressive pneumonia virus (ppv), two antigenically related, non-oncogenic "slow viruses" which have ribonucleic acid (rna)-dependent deoxyribonucleic acid (dna) polymerase activity, were examined for their ability to transform cells. murine cells which had been exposed to either visna or ppv developed foci of altered, spindle-shaped cells 3 to 4 weeks after infection. visna and ppv transformed lines were established from these cultures. there was no evidence that other oncogenic dna ...	1971	4998321

viral inactivation of human osteochondral grafts with methylene blue and light.	cartilage injury is one of the most common disorders of synovial joints. fresh osteochondral allografts are becoming a standard treatment; however, they are supply constrained with a potential risk of disease transmission. there are no known virucidal processes available for osteochondral allografts and most methods presently available are detrimental to cartilage. methylene blue light treatment has been shown to be successful in the literature for viral inactivation of fresh frozen plasma. the ...	0	26069682
