the effect of parainfluenza 3 infection on guinea pig basophil and lung mast cell histamine release.the guinea pig infected with parainfluenza 3 (p-3) has provided an animal model to study mechanisms of virus-induced asthma and airway hyperreactivity. evidence to identify the mechanisms by which p-3 infection enhances airway hyperreactivity, however, has not been established. the present study evaluated the effect of p-3 infection on histamine release (hr) from isolated peripheral blood guinea pig basophils and lung mast cells. basophil hr was determined in animals made basophilic with 13 dail ...19892466427
identification of amino acids recognized by syncytium-inhibiting and neutralizing monoclonal antibodies to the human parainfluenza type 3 virus fusion protein.neutralizing monoclonal antibodies specific for the fusion (f) glycoprotein of human parainfluenza type 3 virus (piv3) were used to select neutralization-resistant antigenic variants. sequence analysis of the f genes of the variants indicated that their resistance to antibody binding, antibody-mediated neutralization or to both was a result of specific amino acid substitutions within the neutralization epitopes of the f1 and f2 subunits. comparison of the locations of piv3 neutralization epitope ...19892474672
presence of an anti-viral factor in peritoneal dialysis effluent.viral peritonitis is an exceptionally rare occurrence in peritoneal dialysis. in fact, up to now, only one case report has been documented in the literature. in a prospective study, peritoneal dialysis effluent (pde) was specifically cultured for the following viruses: the herpes group of viruses, including herpes simplex types i (hsv) and ii, cytomegalovirus (cmv) and varicella-zoster (v-z), and the enteroviruses group including coxsackie b-5 (cox b), echo, enterovirus and polio. cultures were ...19892476580
effects of bovine respiratory disease viruses and isoprinosine on bovine leukocyte function in vitro.peripheral blood mononuclear cells obtained from 4- to 6-month-old-calves were inoculated in vitro with bovine herpesvirus-1, parainfluenza-3, or bovine virus diarrhea viruses. no increase in infectious virus progeny was observed; however, the viruses were detected in the cells for at least 96 h post-infection without any significant reduction in cell viability. the three viruses, either alone or in combination, suppressed phytohemagglutinin-induced proliferation of the mononuclear cells. the gr ...19892477940
identification and partial purification of the fusion protein of avian paramyxovirus type 3.the fusion protein of an avian paramyxovirus-3 from turkeys was detected as a poorly-labelled 56k 3h-glucosamine band. after immunopurification by a monoclonal antibody it elicited antisera which inhibited haemolysis but not haemagglutination.19892481433
defective transport of hemagglutinin-neuraminidase glycoprotein of bovine parainfluenza-3 virus in interferon treated cell.a defective transport of bovine parainfluenza-3 virus (pi-3v) hemagglutinin-neuraminidase (hn) glycoprotein was evidenced in interferon (ifn)-treated bovine turbinate (btu) cells. indirect immunofluorescence performed with monoclonal antibody to pi-3 hn glycoprotein demonstrated accumulation of this protein in the perinuclear cytoplasm of ifn-treated cells. untreated, infected control cells had a generalized widespread fluorescence. unfixed control cells showed a uniform surface fluorescence in ...19892482015
protection of lambs against experimental pneumonic pasteurellosis by transfer of immune serum.passive protection of specific pathogen-free lambs against experimental pasteurellosis was achieved using antisera from conventionally reared sheep which were either convalescent from experimental pneumonia or inoculated with pasteurella haemolytica a2 vaccines. the complete immune sera, or immunoglobulin-rich fractions prepared from them, when administered separately or together provided 94-100% protection of recipients compared to control lambs. antibodies to p. haemolytica in donor sera were ...19892527437
enzyme immunoassays for detection of igg and igm antibodies to parainfluenza types 1, 2 and 3.quantitative enzyme immunoassays for parainfluenza type 1, 2 and 3 igg antibodies were developed. serum specimens were tested at a single dilution of 1:1000 and results expressed in units by the use of a standard curve. the unit values correlated well with titres obtained by testing the same specimens in serial dilutions. all serum pairs with significant titre rises also showed significant rises in unit values. parainfluenza igg and igm serology was evaluated in 66 patients with a proven parainf ...19892536382
bovine herpesvirus-1 and parainfluenza-3 virus interactions: clinical and immunological response in calves.calves infected with bovine herpesvirus-1 (bhv-1) or both bhv-1 and parainfluenza-3 virus (piv-3) developed clinical signs including fever, cough, and nasal and ocular discharges. animals infected with both viruses appeared more depressed and showed higher rectal temperature, while calves inoculated with piv-3 alone had a very mild clinical disease. both bhv-1 and piv-3 were recovered from nasal secretions up to six to eight days postinoculation. however, the virus titers were lower in calves wi ...19892536581
virus-induced enhancement of arachidonate metabolism by bovine alveolar macrophages in vitro.virus infection of alveolar macrophages both in vivo and in vitro has been associated with a variety of changes in cellular function. some of these changes are identical to the effects that arachidonate-derived mediators, prostaglandins, leukotrienes, and hydroxyeicosatetraenoic acids, have on macrophage function. virus infection of macrophages has been previously shown to increase the output of some arachidonate metabolites, most notably pge2. however, the effect of virus infection on arachidon ...19892539424
reversal of virus-induced alveolar macrophage bactericidal dysfunction by cyclooxygenase inhibition in vitro.virus infection of alveolar macrophages (am) both in vivo and in vitro has been associated with a decreased ability of these cells to kill bacteria, together with enhanced production of metabolites of arachidonic acid. these metabolites, especially pge2, may be inhibitory to some phagocyte functions. primary cultures of bovine am obtained by bronchoalveolar lavage of normal cattle were infected in vitro with parainfluenza-3 (pi3 virus) virus. killing of staphylococcus epidermidis by am was deter ...19892539425
analysis of the in vitro antiviral activity of certain ribonucleosides against parainfluenza virus using a novel computer aided receptor modeling procedure.the in vitro antiviral activity of 28 nucleosides against the parainfluenza virus type 3 has been analyzed by using a novel computer aided receptor modeling procedure. the method involves an extensive modification of our earlier work (ghose, a. k.; crippen, g. m. j. med. chem. 1985, 28, 333). it presents a more straightforward algorithm for the steps that suffered from subjectivity in the earlier method. the method first determines the possible low-energy conformations of the nucleosides, and as ...19892539476
a neutrophil-derived antiviral protein: induction requirements and biological properties.polymorphonuclear neutrophilic granulocytes (pmn) have been implicated as playing a role in antiviral defense. in addition to having phagocytic and cytotoxic activities, pmn may produce an antiviral substance with interferon (ifn)-like activity. the product, for which the name polyferon (pf) has been coined, is produced upon direct encounter of pmn with bovine herpesvirus 1 (bhv-1)-infected bovine cells or membranes thereof. exposure to purified virus only does not induce pf. the intimate intera ...19892539494
expression of the fusion glycoprotein of human parainfluenza type 3 virus in insect cells by a recombinant baculovirus and analysis of its immunogenic property.the fusion (f) glycoprotein of human parainfluenza type 3 (pi3) virus was produced in insect cells using a baculovirus expression vector (pacym1). the recombinant glycoprotein was identified by its reactivity with specific monoclonal and polyclonal antibodies and showed an apparent molecular mass of 70 kda. although the fusion protein was found on the infected cell surface, it did not appear to be proteolytically cleaved to f1 and f2 subunits. immunization of hamsters with the recombinant protei ...19892539707

[mechanism of penetration of human type 3 parainfluenza virus into monkey kidney cells].the mechanism of human parainfluenza type 3 virus penetration into monkey kidney cells was studied by morphological and biochemical methods. the results of electron microscopic studies permit a conclusion that the virus penetrates into the cells by the mechanism of receptor endocytosis. analysis of subvirus structures in cytosole revealed two types of particles: nucleocapsids and structures of a larger size and lower buoyant density containing, in addition to np protein, matrix (m) protein. it i ...19892543139
epidemiology of parainfluenza virus type 3 in england and wales over a ten-year period.we have analysed data on respiratory syncytial (rs) and parainfluenza type 3 (pf3) viruses reported to the communicable disease surveillance centre, london, over the period 1978-87. these confirm the annual winter epidemic of rs virus and show that, in england and wales, pf3 is a summer infection with regular yearly epidemics.19892544442
synthesis of 3-deazaneplanocin a, a powerful inhibitor of s-adenosylhomocysteine hydrolase with potent and selective in vitro and in vivo antiviral activities.the neplanocin a analogue 3-deazaneplanocin a (2b) has been synthesized. a direct sn2 displacement on the cyclopentenyl mesylate 3 by the sodium salt of 6-chloro-3-deazapurine afforded the desired regioisomer 4 as the major product. after deprotection, this material was converted to 3-deazaneplanocin a in two steps. x-ray crystallographic analysis confirmed the assigned structure. consistent with its potent inhibition of s-adenosylhomocysteine hydrolase, 3-deazaneplanocin a displayed excellent a ...19892544721
acute inflammatory lung injury retards pulmonary particle clearance.the deposition, retention, and clearance of inhaled cobalt oxide particles from the lungs of calves with acute inflammatory lung injury induced by parainfluenza-3 virus (pi-3) were examined. acute pulmonary inflammation was induced by nebulization with 10(9) tcid50 of pi-3 virus on two successive days, and animals were subsequently exposed to an aerosol of particulate cobalt oxide (geometric mean diameter 0.54-0.65 microns) seven days post-virus infection (dpi). pulmonary lesions at 7 dpi were t ...19892547712
syncytium formation by recombinant vaccinia viruses carrying bovine parainfluenza 3 virus envelope protein genes.the highly syncytium-inducing m strain and the weakly syncytium-inducing sc strain of bovine parainfluenza 3 virus differ by a single amino acid substitution in each of the hemagglutinin-neuraminidase (hn) and membrane (m) proteins, while their fusion (f) proteins are identical (t. shioda, s. wakao, s. suzu, and h. shibuta, virology 162:388-396, 1988). we constructed recombinant vaccinia viruses which express separately the m virus hn (vac-mhn), sc virus hn (vac-schn), m virus m (vac-mm), sc vir ...19892547990
[comparative study of the hemolytic activity of ortho- and paramyxoviruses].a comparative study of hemolytic activity of influenza type a, b, and c viruses, human parainfluenza type 3, and sendai virus showed the pattern of ph-dependence and the nature of the curve to differ not only for different viruses under study but also for different erythrocyte species. studies of virus-induced hemolysis of influenza c virus demonstrated that, depending on the erythrocyte species used, it had common properties both with influenza types a and b viruses and with paramyxoviruses.19892548343

parainfluenza 3 vaccination of sheep.outbreaks of pneumonia associated with pasteurella haemolytica have occurred in sheep in the area of perthshire served by this practice, and on some farms the disease has been an important annual cause of loss. serological evidence was obtained that parainfluenza 3 (pi3) virus might be implicated as a predisposing factor to pasteurellosis. a live attenuated pi3 virus vaccine licensed for use in cattle was given intranasally to ewes on one farm. many sheep seroconverted and outbreaks of pneumonia ...19892556831
epidemiologic survey of bovine diseases in suriname.a seroepidemiologic survey of cattle diseases was undertaken in suriname in 1985 to help assess the livestock disease situation in that country. the six diseases covered by the survey were bovine coronavirus infection, bovine rhinotracheitis, bovine virus diarrhea, brucellosis, parainfluenza-3 infection, and respiratory syncytial virus infection. the results indicated relatively low prevalences of these diseases compared to the prevalences found in most developed countries. the reasons for this ...19892558753
[serum antibody titers against various viruses in idiopathic interstitial pneumonia].as the first step to investigate a possibility that viral infection is involved in the pathogenesis of idiopathic interstitial pneumonia (iip), serum antibody titers against various viruses were studied in 98 iip patients. the patients were positive for herpes simplex virus, cytomegalovirus, rubella virus, parainfluenza virus 3, ebv-vca igg and adeno virus 1, which were also assessed in 45 normal subjects. as results, iip patients showed higher titers of ebv-vca igg (p less than 0.01). when the ...19892559226
studies of the effect of recombinant human-alpha 1 interferon on experimental parainfluenza type 3 virus infections of the respiratory tract of calves.the effect of the administration of recombinant human interferon on the severity of clinical disease and the extent of pneumonic lesions in calves infected experimentally with bovine parainfluenza 3 (pi3) virus was studied in two experiments. in the first, three pairs of calves aged seven to 10 days were used; one of each pair was injected intramuscularly with 10(6) units of interferon/kg bodyweight for three consecutive days, and the other was left untreated. on the day after the first injectio ...19892559530
an evaluation of four serological tests for the detection of antibodies to bovine parainfluenza virus type 3.haemagglutination-inhibition (hi), virus neutralization (vn), haemolysis-inhibition (hli-1, hli-2) tests, and two new haemofusion-inhibition (hfi-1, hfi-2) tests, developed by us, were tested for the detection of antibodies to bovine parainfluenza virus type 3 (bpiv-3) in sera of 45 steers randomly selected from a herd naturally infected by bpiv-3. twelve seronegative animals were then vaccinated with formalin-inactivated vaccine and 15 days later tested by the above-mentioned assays. linear reg ...19892561663
quantitative method of measuring anti-viral activity of peritoneal dialysis effluent.we have previously documented the presence of anti-viral activity in the peritoneal effluent of uremic patients treated by peritoneal dialysis. anti-viral activity was determined by recording the inhibition of the cytopathic effect (cpe) of various viruses on vero cells in a semi-quantitative manner based on observer's subjective judgment of the degree of inhibition of cpe. this degree of inhibition is a measure of the anti-viral activity. although peritoneal dialysis effluent (pde) was consiste ...19892577401
rapid detection of influenza virus infections in human fetal lung diploid cell cultures.haemadsorbing foci were found in human fetal lung (hfl) diploid cell cultures 12 h after inoculation with influenza viruses a and b. the size and number of the foci were maximal after 48 h of incubation, being limited by production of an unidentified inhibitor. by contrast, inoculation with parainfluenza virus type 3 led to haemadsorption which increased during 10 days of incubation. for the detection of influenza viruses a and b maximum sensitivity was achieved by changing the medium, the day b ...19892663998
the mumps virus nucleocapsid mrna sequence and homology among the paramyxoviridae proteins.the nucleotide sequence of mumps virus nucleocapsid protein (np) mrna has been determined from two overlapping cdna clones and confirmed by partial sequencing of the mrna and the genome. the mrna contains 1844 nucleotides excluding poly(a) and encodes a protein of 553 amino acids with a calculated molecular weight of 61,792. a comparison of the mumps virus nucleocapsid protein sequence with that of other paramyxoviruses revealed a moderate degree of homology (33.1%) with the newcastle disease vi ...19892718626
