| are the 2-isomers of the drug rimantadine active anti-influenza a agents? | there is a lack of information in the medical chemistry literature concerning the anti-influenza a activity of the drug rimantadine's 2-isomer (2-rimantadine). we now present results showing that, although 2-adamantanamine (2-amantadine) 3 is only moderately active, some 2-rimantadine analogues are effective anti-influenza a virus agents in vitro. the 2-rimantadine analogues and their spirocyclobutane and spirocyclopentane congeners were synthesized through interesting routes. the 2-rimantadine ... | 2003 | 14521332 |

| emergence of amantadine-resistant influenza a viruses: epidemiological study. | at present, three licensed antiviral influenza agents are available in japan: amantadine, zanamivir, and oseltamivir. these antiviral agents can be used for controlling and preventing influenza, but they are not a substitute for vaccination. amantadine is an antiviral drug with activity against influenza a viruses, but not influenza b viruses. persons who have influenza a infection and who are treated with amantadine can shed sensitive viruses early in the course of treatment and later shed drug ... | 2003 | 14513385 |
| update: influenza activity--united states and worldwide, may-september 2003. | during may-september 2003, influenza a(h3n2) viruses circulated worldwide and were associated with mild to moderate levels of disease activity. influenza a(h1) and b viruses were reported less frequently. in north america, isolates of influenza a(h3n2), a(h1), and b were identified sporadically. this report summarizes influenza activity in the united states and worldwide during may-september 2003. influenza activity in north america typically peaks during december-march, which underscores the ne ... | 2003 | 14508440 |
| comparison of conventional viral cultures with direct fluorescent antibody stains for diagnosis of community-acquired respiratory virus infections in hospitalized children. | because of the widespread availability of rapid viral antigen testing, many institutions never adopted a routine practice of ordering viral cultures to detect community-acquired respiratory viruses (crvs). the ease of performing complete viral studies in our on site laboratory allowed us to assess the clinical implications of the absence of conventional culture results in previously healthy hospitalized children with crv infections. | 2003 | 14506369 |
| evolution of surface and nonstructural-1 genes of influenza b viruses isolated in the province of québec, canada, during the 1998-2001 period. | after 2 minor winter seasons, influenza b viruses were predominantly isolated in the province of quebec, canada, during the 2000-2001 season representing 74% of laboratory-confirmed influenza viruses. we performed an antigenic study of the hemagglutinin (ha) protein and a molecular characterization of the ha1 region, nonstructural-1 (ns1) and neuraminidase (na)/nb genes of 20 influenza b strains isolated in the province of quebec during the 1998-2001 period. our isolates were compared to recent ... | 2003 | 14501190 |

| [the viruses of the 1952-3 influenza epidemic]. | the results of antigenic studies of the viruses received at the world influenza centre from the 1952-3 influenza epidemic are described. as in 1950-1, two main antigenic groups of influenza a viruses could be distinguished. one group, called liverpool, contained strains closely related to 1950-1 liverpool strains. the other, called scandinavian, contained strains related to but not identical with 1950-1 scandinavian viruses. altogether, 175 scandinavian, 33 liverpool, and 4 influenza b virus str ... | 1954 | 14364180 |
| reactivation of non-infective virus in a cortisone-injected host. | the administration of cortisone to chick embryos inoculated with large quantities of inactive influenza b virus results in a rate of viral increase greater than is concommittantly observed with inocula of comparable infectivity which are devoid of inactive particles. thus, more than a mere negation of autointerference is effected. it is concluded that in the presence of cortisone reactivation has occurred of non-infective virus to a state in which it can participate in viral synthesis. cortisone ... | 1955 | 14354111 |

| serial propagation of influenza b (lee) virus in a transmissible line of canine kidney cells. | the serial propagation of influenza b (lee) virus has been demonstrated in a transmissible line of canine kidney cells, as evidenced by the presence of cytopathic effects and hemagglutinins in each of six consecutive tissue-culture passages, and by egg infectivity titers of 10-4.3 and 10-4.1 per 0.1 ml in 3rd and 5th tissue culture fluids, respectively. | 1962 | 13901412 |

| relationship between structure of benzimidazole derivatives and selective virus inhibitory activity. inhibition of poliovirus multiplication and cytopathic effects by 2-(alpha-hydroxybenzyl)-benzimidazole, and its 5-chloroderivative. | the virus inhibitory activity and selectivity of certain benzimidazole, benzotriazole, and naphthimidazole derivatives were determined with influenza b and polio type 2 viruses. among the sixty-five compounds examined, several were highly active inhibitors of influenza b virus multiplication in the chorioallantoic membrane in vitro. the following compounds, listed in order of increasing inhibitory activity, were more than 100 times as active as benzimidazole: 5-(4'-toluenesulfonamido)-benzimidaz ... | 1961 | 13775109 |

| phylogenetic analysis reveals a low rate of homologous recombination in negative-sense rna viruses. | recombination is increasingly seen as an important means of shaping genetic diversity in rna viruses. however, observed recombination frequencies vary widely among those viruses studied to date, with only sporadic occurrences reported in rna viruses with negative-sense genomes. to determine the extent of homologous recombination in negative-sense rna viruses, phylogenetic analyses of 79 gene sequence alignments from 35 negative-sense rna viruses (a total of 2154 sequences) were carried out. powe ... | 2003 | 13679603 |

| enzymatic variants of influenza virus. ii. effect of environmental factors on enzymatic characteristics of a variant of influenza b virus. | the rate of elution of the variant virus from chicken rbc is progressively decreased as the temperature of incubation is increased above 25 degrees c. the activity of the parent virus, on the other hand, is increased as the temperature is increased up to 40 degrees c. the major cause of the decreased activity of the variant at temperatures above 2s degrees c. is an inhibition of the variant enzyme rather than its inactivation. the activity of the variant enzyme is stimulated in the presence of s ... | 1958 | 13587849 |

| the influence of cortisone on experimental viral infection. iv. negation of interference as the mechanism by which cortisone induces increased virus yields. | the interference with viral synthesis which is induced by large quantities of non-infective influenza b virus is inhibited or negated with small quantities of cortisone and other c-21 steroids. the specificity of this effect is attested by the inactivity of 11-alpha hydroxy epimers of highly active compounds. maximal activity in negation of interference is associated with the presence of oxygen at the c-11 position of the steroid molecule. in view of the demonstration that negation of interferen ... | 1957 | 13481249 |
| the influence of cortisone on experimental viral infection. iil effects on certain dynamics of influenza virus increase. | the administration of cortisone to chicken embryos infected with influenza b virus results in (a) an initial inhibition of viral synthesis and (b) an eventual increase in the final yield of virus attained. increased yields of virus are attained regardless of the number of viral particles in the infecting inoculum or the proportion of particles which are infective. changes in the distribution ratios of allantoic fluid and intramembrane virus are effected by cortisone only as the secondary result ... | 1957 | 13481248 |
