| a hypothesis accounting for the effect of the host cell on neutralization-resistant virus. | evidence is presented showing that a monkey anti-enterovirus 71 immune serum contains several antibody populations which differ in their mode of function. one population reduces infectivity, although inefficiently, by interactions at exposed antigenic sites and can be detected by measuring residual virus infectivity after mixtures of virus and antibody have been allowed to interact. another antibody population, which is unaffected by the immunosorbent staphylococcus aureus (cowan i strain), appe ... | 1985 | 2995563 |
| protective effect of interferon on infections with hand, foot, and mouth disease virus in newborn mice. | the protective effect of interferon on infection with coxsackievirus type a 16 (ca-16) or enterovirus type 71 (ev-71) in newborn mice was examined. subcutaneous administration of murine interferon (muifn-alpha/beta) into the infected mice produced a protective effect against infection with ca-16 or ev-71. it was found that the time of administration of muifn was important in relation to the cycle of infection. protection was observed when muifn was given once daily for several days, from one day ... | 1986 | 3005425 |

| [serotype determination of enteroviruses that cause hand-foot-mouth disease; identification of enterovirus 71 and coxsackievirus a16 from clinical specimens by using specific probe]. | coxsackievirus a16 (ca16) and enterovirus 71 (ev71) are known to be major causative agents of hand-foot-and-mouth disease prevalent in summer in japan. discrimination and identification of these viruses were often hampered by a nonneutralizable or nontypable virus. therefore, a southern blot hybridization that utilizes mixed probes specific to serotype was developed. firstly, an approximately 650 bases spanning 5'-noncoding region to one third of vp2 including entire vp4 was amplified with a set ... | 1997 | 9311187 |
| complete nucleotide sequence of enterovirus 71 is distinct from poliovirus. | enterovirus 71 (ev71) is capable of causing paralytic disease indistinguishable from poliomyelitis due to poliovirus. to determine the relationship of ev71 to poliovirus and other enteroviruses, two strains of ev71 have been cloned and sequenced. the ev71 strains had only 46% amino acid identity with the polioviral p1 capsid region and 55% with the entire polyprotein. there were no regions of high similarity that might account for their respective ability to cause paralytic disease. the two stra ... | 1995 | 8837884 |
| enterovirus 71 isolated from china is serologically similar to the prototype e71 brcr strain but differs in the 5'-noncoding region. | enterovirus 71 h (e71 h), an isolate from an adult patient with hand-food-mouth disease (hfmd) in china, was serologically similar to the prototype strain e71 brcr, which was isolated from a patient with aseptic meningitis. the study further analyzed the similarity of e71 h to e71 brcr at the 5'-noncoding region (ncr), a location in genomic rna that recently was found to be related to neurovirulence in poliovirus and venezuelan equine encephalitis virus. using a reverse transcription-polymerase ... | 1995 | 8830120 |

| serotype-specific identification of enterovirus 71 by pcr. | enterovirus 71 and coxsackievirus a16 are closely related genetically and are causative agents of hand foot and mouth disease. because enterovirus 71 is more often associated with severe neurological disease, there is a need to rapidly discriminate between enterovirus 71 and coxsackievirus a16 during hand, foot, and mouth disease outbreaks. | 2000 | 10720814 |
| chiral discrimination and antipicornavirus activity of 6-oxazolinylisoflavan. | racemic 6-oxazolinylisoflavan, a highly effective inhibitor of rhinovirus serotype 1b in vitro, was resolved by high-performance liquid chromatography on a chiral stationary phase in order to study the activity of the enantiomers against picornaviruses. the absolute configuration of the two isomers was determined by circular dichroism curves. the antipicornavirus activity of each isomer, separately collected, was evaluated in vitro against human rhinovirus serotype 1b, enterovirus 71, echovirus ... | 1993 | 8398593 |
| enterovirus infections with special reference to enterovirus 71. | the enteroviruses comprise a large group of immunologically distinct serotypes of viruses belonging to the family of picornaviridae. many enteroviruses cause diseases in human, but the infections are generally mild as asymptomatic, therefore, enteroviruses are considered to be unimportant as human pathogens. however, enteroviruses may also result in serious or even fatal disease (as shown in the enterovirus 71 (ev71) epidemic in taiwan in 1998). there are three types of polioviruses, coxsackievi ... | 2000 | 10806956 |
| enterovirus 71 from fatal and nonfatal cases of hand, foot and mouth disease epidemics in malaysia, japan and taiwan in 1997-1998. | enterovirus 71 (ev71), one of the major causative agents for hand, foot and mouth disease (hfmd), is sometimes associated with severe central nervous system diseases. in 1997, in malaysia and japan, and in 1998 in taiwan, there were hfmd epidemics involving sudden deaths among young children, and ev71 was isolated from the hfmd patients, including the fatal cases. the nucleotide sequences of each ev71 isolate were determined and compared by phylogenetical analysis. ev71 strains from previously r ... | 1999 | 10808253 |
