who collaborative studies on enterovirus reference antisera; fourth report. | this paper summarizes the results of the fourth part of a comprehensive programme undertaken by the who international reference centre for enteroviruses and other laboratories for the testing of enterovirus equine antisera prepared for long-term use as reference antisera. the studies were designed to appraise the specificity of the immune serum of horses inoculated with prototype enteroviruses (coxsackievirus types a2, 4, 8, 10, 11, 14-16, 18-21, and 24, and echoviruses e21, 27, 30, 31, and 33). ... | 1973 | 4357975 |
molecular comparison of coxsackie a virus serotypes. | genetic diversity of coxsackie a viruses (cavs) and enteroviruses 68, 69, and 71 was studied by comparing nucleotide and derived amino acid sequences from the 5' untranslated region (5'utr), vp4-vp2 capsid protein and polymerase 3d region, and 3'utr. the data were obtained by sequencing pcr amplicons. according to the molecular analysis of the coding region, cavs belong to three different genetic clusters. cav2, 3, 5, 7, 8, 10, 12, 14, and 16 form a coherent genetic group designated cluster a. n ... | 1995 | 7676647 |
variation in liposome binding among enteroviruses. | liposome-binding properties of native virions and in vitro generated 135s particles of eight enteroviruses were studied. the temperature required for the structural transition from the native 160s virion to a 135s particle was virus-specific, ranging from +38 degrees c to more than +50 degrees c. while the 135s particles of poliovirus 1/mahoney (pv1) and coxsackievirus a21 (cav21) were capable of binding to liposomes, the other viruses showed minimal binding. both of the viruses that bound to li ... | 2001 | 11162809 |
design, synthesis, and structure-activity relationship of pyridyl imidazolidinones: a novel class of potent and selective human enterovirus 71 inhibitors. | when skeletons of win compounds were used as templates, computer-assisted drug design led to the identification of a novel series of imidazolidinone derivatives with significant antiviral activity against enterovirus 71 (ev 71), the infection of which had resulted in about 80 fatalities during the 1998 epidemic outbreak in taiwan. in addition to inhibiting all the genotypes (a, b, and c) of ev 71 in the submicromolar to low micromolar range, compounds 1 and 8 were extensively evaluated against a ... | 2002 | 11931618 |
neutralizing antibodies to enterovirus 71 in belém, brazil. | non-polio enteroviruses (coxsackievirus a, coxsackievirus b, echovirus and ev 68-72) which belong to the enterovirus (ev) genus, picornaviridae family, may be responsible for acute flaccid paralysis, aseptic meningitis, myocarditis, hepatitis, pleurodinia, neonatal sepsis, hand, foot and mouth disease (hfmd) even though 50-80% of infections are asymptomatic. ev 71 has been responsible for outbreaks and epidemics of hfmd and acute neurologic disease justifying its study in our country. the aim of ... | 2002 | 11992146 |
human rhinovirus 87 identified as human enterovirus 68 by vp4-based molecular diagnosis. | human rhinoviruses (hrvs) are the major cause of respiratory infections. we developed a diagnostic method for hrvs based on the reverse-transcription polymerase chain reaction (rt-pcr) and vp4-based phylogenetic analysis. a set of primers used in the rt-pcr of human enteroviruses (evs) appeared to be capable of amplifying all prototype strains of hrvs, each of which generated a 530-bp fragment. the single exception was hrv-87, which generated a 650-bp fragment, as observed in human evs. the vp4 ... | 2002 | 12403917 |
human rhinovirus 87 and enterovirus 68 represent a unique serotype with rhinovirus and enterovirus features. | it has recently been reported that all but one of the 102 known serotypes of the genus rhinovirus segregate into two genetic clusters (c. savolainen, s. blomqvist, m. n. mulders, and t. hovi, j. gen. virol. 83:333-340, 2002). the only exception is human rhinovirus 87 (hrv87). here we demonstrate that hrv87 is genetically and antigenically highly similar to enterovirus 68 (ev68) and is related to ev70, the other member of human enterovirus group d. the partial nucleotide sequences of the 5' untra ... | 2002 | 12409401 |
enterovirus 68 is associated with respiratory illness and shares biological features with both the enteroviruses and the rhinoviruses. | enterovirus (ev) 68 was originally isolated in california in 1962 from four children with respiratory illness. since that time, reports of ev68 isolation have been very uncommon. between 1989 and 2003, 12 additional ev68 clinical isolates were identified and characterized, all of which were obtained from respiratory specimens of patients with respiratory tract illnesses. no ev68 isolates from enteric specimens have been identified from these same laboratories. these recent isolates, as well as t ... | 2004 | 15302951 |

performance of enterovirus genotyping targeting the vp1 and vp2 regions on non-typeable isolates and patient specimens. | culture and serotyping of human enteroviruses are time-consuming and labor-intensive. targeted nucleic acid sequencing has emerged as a powerful alternative to conventional methods. many published genotyping assays use two-step reverse transcription and polymerase chain reaction (rt-pcr), nested pcr protocols, and/or reflexive testing algorithms. the performance of a one-step rt-pcr protocol, a more clinically practical approach, was evaluated. the vp1 and/or vp2 region of archived enterovirus i ... | 2010 | 20043951 |
broad spectrum respiratory pathogen analysis of throat swabs from military recruits reveals interference between rhinoviruses and adenoviruses. | military recruits experience a high incidence of febrile respiratory illness (fri), leading to significant morbidity and lost training time. adenoviruses, group a streptococcus pyogenes, and influenza virus are implicated in over half of the fri cases reported at recruit training center clinics, while the etiology of the remaining cases is unclear. in this study, we explore the carriage rates and disease associations of adenovirus, enterovirus, rhinovirus, streptococcus pneumoniae, haemophilus i ... | 2010 | 20217405 |
