electrophoretic analysis of capsid and non-capsid polypeptides of echovirus 12, and selective inhibtion of the formation of virus particles by actinomycin d.electrophoretic analysis of purified echovirus virus particles yielded four polypeptides of mol. wt. 37000, 30000, 25000 and 7600. the 75s empty capsids of echovirus 12 lack the 25000 and 7600 mol. wt. polypeptides, and possess polypeptides of 41000 mol. wt. a total of 14 virus-induced polypeptide species was found in the cytoplasm of infected cells. actinomycin d reduced the synthesis of virus, virus rna, and virus polypeptides and also reduced the proportion of virus particles to empty capsid ...19751168242
sequelae of central-nervous-system enterovirus infections.the long-term effects of central-nervous-system enterovirus infections were examined in a controlled follow-up study of 19 children 2 1/2 to eight years of age who had been hospitalized with documented enterovirus infection 17 to 67 months before evaluation. assessment included medical history, physical and neurologic examination, psychologic testing, and speech and hearing evaluation. three children (16 per cent) had definite neurologic impairment, five (26 per cent) had possible impairment, an ...19751168853
[virologic and serologic findings in an epidemic of abacterial meningitis of unknown origin (author's transl)].in the summer of 1972 there occurred an epidemic of abacterial meningitis in bayreuth and its surroundings. we received material of 52 ill children, aged 2 months to 14 years. a virus could be isolated in 10 (5 coxsackie a4, 2 echo 6, 1 coxsackie b 5 and twice enterovirus which would not be typed). only in another 13 children could we make unequivocal diagnoses (7 coxsackie a4, 2 coxsackie b5, one each coxsackie a 2, echo 3, mumps, rrs-virus). with the other 29 patients a safe laboratory diagnos ...19751172156
prevalence of hepatitis b antibody in prostitutes.the possibility that hepatitis b is transmitted venereally was examined by determining the prevalence of hepatitis b antibody (anti-hb(s)) in populations with different levels of promiscuity. of 258 prostitutes, 31% were anti-hb(s) positive, compared to 10% of 258 female age-matched blood donors, 10% of 48 nuns living in a convent and 15% of 94 nuns working as teachers. prevalence of anti-hb(s) increased with increasing age. in the age group 40-49 years up to 72% of prostitutes were anti-hb(s) p ...19751174290
propagation and isolation of group a coxsackieviruses in rd cells.the rd cell line, derived from a human rhabdomyosarcoma, supported replication of a number of group a coxsackieviruses, including types a5 and a6 which heretofore have been propagable only in suckling mice. a number of the group a coxsackievirus types which replicated in rd cells had higher titers in this cell line than in other cell culture systems. in tests on a limited number of clinical specimens, rd cells were slightly less sensitive than suckling mice for isolation of group a coxsackieviru ...19751176625
hand, foot and mouth disease associated with coxsackievirus group b.this study from frankfurt, although similar to other reports with respect to clinical findings, presents further evidence of a varied etiology for hand, foot and mouth disease (hfmd). of the 6 patients with hfmd, 5 ahd virologic evidence of coxsackievirus b5 infection, and 1 had definite evidence of coxsackievirus b2 infection. our data suggest an etiologic association of coxsackievirus group b with hfmd.19751179172
a local outbreak of paralytic rabies in surinam children.a rapidly fatal encephalomyelitis, which was in most cases characterized by ascending paralysis, developed in seven children of the age of 3 to 10 years in a bushnegro village in the interior of surinam. rabies virus was recovered from the central nervous system of three autopsied children. although the source of infection has not been detected, there is an indication that, at least in some cases, the disease has been transmitted by rat-bite rather than by vampire bats. during the same period a ...19751179478
epidemic pleurodynia (bornholm disease) outbreak in singapore. a clinical and virological study.in 1974, an outbreak of bornholm disease occurred in singapore. the period 1st may to 31st july was delineated for study. from the clinical presentation 53 patients were placed into two categories "typical bornholm disease" and "atypical bornholm disease". the clinical features of only those in the "typical bornholm disease" group including those with positive coxsackie b3 virus isolation were described. the virological studies, both faecal isolation for virus and serology were correlated with c ...19751179480

familial hepatic venoocclusive disease with probable immune deficiency.five infants from three families died between the ages of 2 and 7 months with venocclusive disease of the liver. no dietary, toxic, or other extrinsic cause was uncovered. in one family the first infant was breast-fed; the second one received no breast milk. in two of the families the parents were cousins. all infants had some evidence of immune deficiency, including hypogammaglobulinemia in at least three, multiple infections especially pnumocystis carnii and enteroviruses, and lymphoid tissues ...19761249685
interferon and neutralizing antibody in sera of exercised mice with coxsackievirus b-3 myocarditis.weanling icr albino swiss mice were inoculated ip with 1.9 x 10(4) pfu of coxsackievirus b-3 (nancy) and subsequently forced to swim vigorously daily in a preheated pool (33 degrees). viremias and virus in hearts of exercised mice were respectively 75 x 1000 x greater than in infected, but not exercised mice. at 24 hr after inoculation, pooled serum from mice that had been swum had no circulating interferon, while infected but not swum mice had interferon activity at a dilution of 1:10. at 72 hr ...19761250870
oyster-associated hepatitis: lessons from the louisiana experience.an outbreak of oyster-associated hepatitis occurring in louisiana during the months of october and november 1973 has been shown to be related directly to two similar outbreaks occurring at the same time in houston, texas and calhoun, georgia. oysters incriminated in all three outbreaks were traced to approved oyster growing areas along the east louisiana coast. although no entirely satisfactory explanation could be found for the mode of contamination of these oysters, the epidemiologic and envio ...19761251833
autoimmunity and viral infection in diabetes mellitus.forty-three newly diagnosed insulin-dependent diabetics and thirty control subjects have been examined for cellular hypersensitivity to different pancreatic preparations, rat liver mitochondria and coxsackie b4 virus. evidence for cellular hypersensitivity to the pancreatic preparations was shown in the diabetic group, in whom the hypersensitivity to the pancreatic preparations was found to correlate with hypersensitivity to rat liver mitochondria. hypersensitivity to coxsackie b4 virus was not ...19761261089
application of systolic time intervals to acute cardiomyopathy with echovirous 2.the occurrence of echovirus type 2 myocarditis in an adult is reported. myocarditis was substantiated by abnormal electrocardiograms. more important, a prolonged course and severe functional impairment was quantitatively assessed by serial systolic time intervals, even after the ecgs became normal. the patient also had meningitis, hemiparesis, and convulsions. viral isolation was from the spinal fluid.19761261332
maturation of intestinal defenses against peroral infection with group b coxsackievirus in mice.the intestinal tract of adult mice provides effective protection against peroral infection with group b coxsackievirus. this protective function consists of at least two separate components. one is a barrier effect that prevents virus from passing through the mucosal side of the gut into the circulation. it becomes clearly evident at 18 days of life and is present thereafter. the other is a clearance mechanism that acts to eliminate virus from the enteric tract after infection has occurred. this ...19761270146
successful treatment of enterovirus-infected mice by 2-(alpha-hydroxybenzyl)-benzimidazole and guanidine.echo virus 9- or coxsackie a 9-infected newborn mice are protected from paralysis and death by combined treatment with nontoxic concentrations of hbb plus guanidine. hbb alone also protects coxsackie a 9, but not echo virus 9-infected animals, whereas guanidine alone is ineffective in either case. protection is due to inhibition of virus multiplication via the antiviral activity of these selective inhibitors. treatment must be begun at the latest 48 h after virus inoculation. 3 days of treatment ...19761271013

vacuolar neuronal degeneration in the ventral horns of scid mice in naturally occurring theiler's encephalomyelitis.during a spontaneous outbreak of theiler's encephalomyelitis severe combined immunodeficient mice developed high morbidity and high mortality. histological lesions were localized in the ventral horns of the spinal cord and brain stem. the salient features were the severe vacuolar degeneration of neurones and glial cells and the absence of inflammatory cellular infiltrates. the clinical and pathological features of this outbreak indicate that the scid mouse would be a much improved model for stud ...19921291587
protective effect of a monoclonal antibody specific for an echovirus cellular receptor in human fibroblast and simian kidney cell lines.we previously reported that infection of kb cells by echoviruses (ev) was inhibited by a kb-derived ev receptor murine monoclonal antibody (mab 143). this antibody enabled the identification of a cellular receptor common to all echoviruses (with the exception of ev-22 and -23) and coxsackievirus (cv) a9, but different from the receptor of other picornaviruses. we now present results of cell protection assays conducted with human and simian cell lines different from the kb cell line used for prod ...19921297174
[the humoral immunity indices of patients with malignant skin melanoma using the viral immunomodulator rigvir].the effect of a viral immunomodulator rigvir on humoral immunity was studied in patients with skin malignant melanoma. peripheral blood levels of b-lymphocytes, iga, g and m and circulating immune complexes were assayed and immunoglobulin/b-cell ratio (ig/b) calculated. preoperative treatment with rigvir brought the indexes of humoral immunity to normal. response of melanoma patients to rigvir treatment was different from that seen in healthy subjects and was determined by the course of disease.19921300751
[the cellular immunity indices of patients with malignant melanoma using the viral immunomodulator rigvir].the effect of rigvir, an immunomodulator of the viral origin, on cell-mediated immunity was studied in patients with skin malignant melanoma. rosette formation and monoclonal antibody techniques were used to measure blood immunocompetent cell levels in patients with the above pathology, cases of benign skin tumors and healthy subjects. rigvir was shown to influence natural resistance by raising blood monocyte and large granule-containing lymphocyte levels. it potentiated recruitment of pre-t-lym ...19921300752
[the reaction of the t-immunity system in patients with malignant skin melanoma and stomach cancer to active nonspecific immunotherapy].changes in e-receptor-bearing t-lymphocyte level (total and that of active t-lymphocytes) were studied in peripheral blood and resected material obtained from skin malignant melanoma and gastric cancer patients treated with rigvir, an original immunomodulator of the viral origin. injection of rigvir into peripheral blood was followed by an increase in active t-lymphocyte level and stimulated their migration into tumor. the latter was determined by stage and rate of tumor advancement.19921300766
acute hemorrhagic conjunctivitis.acute hemorrhagic conjunctivitis, an infection caused by enterovirus 70 and a variant of coxsackievirus a24, is characterized by the rapid onset of severely painful conjunctivitis and subconjunctival hemorrhage. the condition is usually benign and resolves in five to seven days; however, a polio-like paralysis (radiculomyelitis) develops in approximately one in 10,000 patients infected with enterovirus 70. no treatment is available. information about acute hemorrhagic conjunctivitis should be pr ...19921309404
ongoing enterovirus-induced myocarditis is associated with persistent heart muscle infection: quantitative analysis of virus replication, tissue damage, and inflammation.coxsackievirus b3-induced myocarditis in different immunocompetent mouse strains was used as a model to investigate interrelationships between virus replication and development of chronic enteroviral heart disease. using in situ hybridization to detect enteroviral rna, we show that heart muscle infection is not only detected in acute myocarditis but is also detected during the chronic phase of the disease. coxsackievirus b3 could evade immunological surveillance in a host-dependent fashion, thus ...19921309611
role of t cell receptor v beta genes in theiler's virus-induced demyelination of mice.intracerebral infection of certain strains of mice with theiler's virus results in chronic immune-mediated demyelination in spinal cord. we used mouse mutants with deletion of the v beta class of tcr genes to examine the role of tcr genes in this demyelinating disease which is similar to multiple sclerosis. quantitative analysis of spinal cord lesions demonstrated a markedly increased number and extent of demyelinated lesions in persistently infected riii s/j mice which have a massive deletion o ...19921309845

enteroviral infection of mice with severe combined immunodeficiency. evidence for direct viral pathogenesis of myocardial injury.inbred mice with genetically determined severe combined immunodeficiency (scid) lack mature t and b lymphocyte functions. to distinguish direct viral effects in the pathogenesis of myocarditis from those mediated by antigen-specific and histocompatibility-complex-restricted host immunity, we inoculated coxsackievirus b3 into homozygous young adult scid mice. we found that infected scid mice invariably developed extensive myocarditis between 7 and 14 days postinoculation with high subsequent mort ...19921309927
coxsackievirus b3 from an infectious cdna copy of the genome is cardiovirulent in mice.a coxsackievirus b3 (cvb3) cdna clone, upon transfection of hela cells, produces cvb3 capable of induction of cardiac inflammation in c3h/he mice by day 8 post inoculation (p.i.). liver and serum are cleared of cvb3 by day 8 p.i., but cvb3 persists in the heart through day 14. the nucleotide sequence and the predicted amino acid sequence of this clone have sites of divergence from 2 other completely sequenced cvb3 genomes although overall identity of the three cvb3 genomes is 99%.19921310000
characterization of the roles of conserved cysteine and histidine residues in poliovirus 2a protease.the primary processing of the poliovirus polyprotein is catalyzed by 2a protease (2apro) which cleaves at the 1d/2a junction in a very rapid cotranslational reaction. in addition, 2apro also indirectly induces cleavage of the p220 component of eif-4f, which results in selective inhibition of host protein synthesis. earlier studies have indicated that 2apro is related to 3c protease (3cpro) and is structurally similar to trypsin-like serine proteases with the substitution of cys109 as the nucleop ...19921310193
ultrastructural alterations of the conduction system in mice exhibiting sinus arrest or heart block during coxsackievirus b3 acute myocarditis.by light and electron microscopy we studied the sinus nodes and atrioventricular (av) conducting tissue of six c3h/he mice having coxsackievirus b3 acute myocarditis. sinus arrest was documented in all six mice, and second- or third-degree av block was documented in three of the six mice. although myocarditic changes in the conduction system, especially in the sinus node, were less than those in atrial and ventricular working myocardium, there were distinct abnormalities within both the sinus no ...19921310565
association of heat shock protein 70 with enterovirus capsid precursor p1 in infected human cells.members of the human heat shock (hsp) family of related proteins are involved in the intracellular folding, transport, and assembly of proteins and protein complexes. we have observed that human heat shock protein 70 (hsp70) is associated with the capsid precursor p1 of poliovirus and coxsackievirus b1 in infected hela cells. antiserum generated against hsp70 coimmunoprecipitated the poliovirus protein p1, an intermediate in capsid assembly. similarly, alpha-virion serum coimmunoprecipitated hsp ...19921310763
cytotoxic and viral neutralizing antibodies crossreact with streptococcal m protein, enteroviruses, and human cardiac myosin.the development of autoimmunity in certain instances is related to infectious agents. in this report, cytotoxic monoclonal antibodies (mabs) that recognize epitopes on both enteroviruses and the bacterium streptococcus pyogenes are described. murine anti-streptococcal mabs that were crossreactive with streptococcal m protein, human cardiac myosin, and other alpha-helical coiled-coil molecules were found to neutralize coxsackieviruses b3 and b4 or poliovirus type 1. the viral-neutralizing anti-st ...19921311095
search for coxsackievirus b3 rna in idiopathic dilated cardiomyopathy using gene amplification by polymerase chain reaction.a polymerase chain reaction (pcr) amplification assay was developed to detect coxsackievirus b3 ribonucleic acid (rna) in blood and myocardial tissue of explanted hearts from 40 patients who underwent cardiac transplantation and in 1 normal heart. twenty-one patients were affected by idiopathic dilated cardiomyopathy of different duration and 19 by coronary artery disease. coxsackievirus b3 in vitro infected vero cells and cells infected by related human enteroviruses (coxsackievirus b2, b4, and ...19921311139
crystallization and preliminary x-ray diffraction studies of coxsackievirus b1.preparations of coxsackievirus b1 (cvb1) derived from an infectious cdna clone have been crystallized in multiple crystal forms. using high intensity synchrotron radiation, an orthorhombic form of the crystals was shown to diffract x-rays to at least 2.9 a resolution. the unit cell has a primitive lattice with dimensions a = 323 a, b = 450 a, and c = 522 a. a crystallographic asymmetric unit of these cvb1 crystals probably contains an entire virus particle, implying the presence of 60-fold non-c ...19921311388
focal ventricular thinning caused by indomethacin in the late phase of coxsackievirus b4 murine myocarditis.indomethacin has been shown to increase virus titers and to worsen cardiac injury in the acute phase of coxsackievirus b4 murine myocarditis. the authors evaluated the effects of indomethacin on the histopathologic changes in a later phase of this disease after virus clearance. two-day old cd1 mice were infected with coxsackievirus b4. ten days later, surviving animals were randomized to receive indomethacin or saline intraperitoneally for 10 days. they were then euthanatized, and their hearts w ...19921311498
transplacental infection of porcine fetuses following experimental challenge inoculation with encephalomyocarditis virus.ten multiparous sows were inoculated between 46 and 50 days of gestation with a fetal swine isolate of encephalomyocarditis virus (emcv) to investigate the ability of the virus to cause transplacental infection and fetal death. four sows (group 1) were inoculated im with emcv mn-25 that had been passaged 4 times on baby hamster kidney-21 line cell monolayers. two sows were euthanatized at postinoculation (pi) day 23, and the other 2 sows at pi day 44. an additional 6 sows (group 2) were inoculat ...19921311538
mumps virus infects beta cells in human fetal islet cell cultures upregulating the expression of hla class i molecules.the ability of mumps virus to infect pancreatic beta cells and cause alterations in their hla expression was evaluated in cultured human fetal islet cell clusters. mumps virus could be isolated during the whole culture period (6-8 days) and 60% of cells, including beta cells, contained viral nucleocapsid protein at the end of the culturing. a minor decrease in insulin secretion was observed in some of the infected cultures. the infection was invariably associated with an increase in the expressi ...19921311693

an experimental model of acute and subacute viral myocarditis in the pig.twenty-six young pigs were infected with encephalomyocarditis virus, observed clinically, studied at intervals by noninvasive and invasive methods to assess cardiac function and eventually examined pathologically. all infected animals appeared ill, usually manifesting diminished appetite, lethargy and fever. spontaneous mortality occurred either 1 to 4 or 20 to 21 days after infection. electrocardiographic abnormalities, seen in the majority of animals, comprised st-t wave changes, conduction di ...19921312100
coxsackievirus b3-induced production of tumor necrosis factor-alpha, il-1 beta, and il-6 in human monocytes.infections by coxsackievirus b3 (cvb3) have previously been shown to cause acute and chronic myocarditis characterized by a heavy mononuclear leukocyte infiltration and myocyte necrosis. because clinical and experimental evidence suggested that cardiac damage may result from immunologic rather than viral mechanisms, we examined in this study the in vitro interaction of cvb3 with human monocytes. cvb3 was capable of infecting freshly harvested monocytes as revealed by immunofluorescence and relea ...19921312105
the nucleotide sequences of wild-type coxsackievirus a9 strains imply that an rgd motif in vp1 is functionally significant.we have shown previously that, compared to other enteroviruses, the coxsackievirus a9 (cav-9) prototype strain, griggs, contains a c-terminal extension to the capsid protein vp1 and that within this extension there is an rgd (arginine-glycine-aspartic acid) motif. to determine whether these features are found in other cav-9 strains and therefore analyse whether they are likely to be functionally important, we have determined the nucleotide sequence of the appropriate region from five strains, is ...19921312121
phylogenetic analysis of a coxsackievirus a24 variant: the most recent worldwide pandemic was caused by progenies of a virus prevalent around 1981.nucleotide substitutions in the viral-encoded proteinase 3c (3cpro) region (549 nucleotides) of the rna genome of a coxsackievirus a24 variant (ca24v), one of the agents causing acute hemorrhagic conjunctivitis (ahc), were studied using 32 isolates collected from the eastern hemisphere in 1970-1989. based on regression analysis of nucleotide differences among isolates, the nucleotide substitution rate of ca24v 3cpro was estimated to be 3.7 x 10(-3)/nucleotide/year. a phylogenetic tree constructe ...19921312276
a 2-year survey of the prevalence of enteric viral infections in children compared with contamination in locally-harvested oysters.we studied, for two years, the prevalence of indigenous human enteric viruses in wild oysters gathered each month from the bottom of mikawa bay, aichi prefecture, japan. viruses were detected periodically in 9 out of 54 oyster pools prepared by the acid or polyethylene glycol precipitation method although all these 9 pools met current national bacteriological safety standards. since most of the serotypes of the enteric viruses detected in the oysters were identical with those of viruses isolated ...19921312478
