13. Comparative sensitivity of the echovirus type 25 JV-4 prototype strain and two recent isolates to glutaraldehyde at low concentrations.

The sensitivity of two recently isolated antigenic variants of echovirus type 25 (Montpellier 76-1262 and Thionville 86-222) to glutaraldehyde (GTA) at low concentrations was compared with that of the JV-4 prototype strain. The purified viruses were treated under the same conditions with GTA at concentrations ranging from 0.002 to 0.10%. The wild strains exh

14. Molecular Evidence of Persistent Echovirus 13 Meningoencephalitis in a Patient with Relapsed Lymphoma after an Outbreak of Meningitis in 2000

Enteroviral meningoencephalitis was diagnosed in a patient with an immunodeficiency syndrome acquired after treatment with rituximab for a relapsed primary B-cell lymphoma. A second meningoencephalitic episode was diagnosed 6 months later and was successfully treated with a combination of immunoglobulins and pleconaril. The infection was persistent since the

15. Human enteroviral infection in fibromyalgia: a case-control blinded study

SUMMARY OBJECTIVE: This study aimed to test the hypothesis that fibromyalgia is associated with a human enteroviral infection. METHODS: Venous peripheral blood samples from 27 patients fulfilling the American College of Rheumatology revised diagnostic criteria for fibromyalgia and from 26 age- and sex-matched controls, who underwent immunofluorescence assa

16. Type-Specific Detection of Echovirus 30 Isolates Using Degenerate Reverse Transcriptase PCR Primers

Following an approach used to specifically identify polioviruses and enterovirus 71, we have developed reverse transcriptase (RT) PCR primers containing mixed-base residues or deoxyinosine at positions of codon degeneracy. These primers permit specific RT-PCR amplification of echovirus 30 (E30) sequences by targeting sites that encode conserved amino acid mo

17. Evidence for secondary structure within the virion RNA of echovirus 22.

Phenol-extracted echovirus 22 virion RNA is infectious, but unlike poliovirus virion RNA, it resists digestion with pancreatic RNase and nuclease P-1, a 3' exonuclease selective for single-stranded RNA. These data indicate the presence of an enzyme-resistant portion somewhere in the RNA molecule and suggest that it is a double-stranded or base-paired region

18. A distinct picornavirus group identified by sequence analysis.

Although echovirus 22 is presently classified as a member of the enterovirus group in the family of picornaviruses, it has been reported to have exceptional biological properties when compared with other representatives of the group. We have determined the complete nucleotide sequence of the echovirus 22 (Harris strain) genome, which appears to be significan

19. Echovirus 6 associado a surto de meningite asséptica em São Joaquim da Barra, São Paulo, Brasil

Entre fevereiro e maio de 2004, em São Joaquim da Barra, Estado de São Paulo, foi notificado ao Centro de Vigilância Epidemiológica (CVE) um surto de meningite asséptica (MA) envolvendo 40 indivíduos. Foram enviadas ao Instituto Adolfo Lutz amostras de líquido cefalorraquidiano (LCR) de 23 pacientes com MA para tentativa de isolamento viral. Estas amo

Bacteriol. 88:1608–1611. 1964.—A variety of conditions for the growth of echovirus 28 were investigated. The virus grew more readily and to the highest titer when secondar

21. Impact on routine diagnosis of echovirus infections of intratypic differentiation and antigenic variation in echovirus type 25 studied by using monoclonal antibodies.

We studied the biological and antigenic properties of wild strains of echovirus type 25 isolated in France between 1982 and 1987 and compared them with the JV-4 prototype strains isolated in 1957. The wild strains differed from the prototype strain in their cellular tropism. The prototype strain grew readily in five cell lines (MRC5, MA 104, Vero, BGM, and H

22. Echovirus 1 interaction with the isolated VLA-2 I domain.

The isolated I domain of the integrin VLA-2, produced as a bacterial fusion protein, specifically bound echovirus 1 and prevented virus attachment to cells. These results demonstrate that the receptor structures critical for virus attachment are contained solely within the VLA-2 I domain and that soluble receptor fragments are capable of preventing infection

23. Fatty Acid-Depleted Albumin Induces the Formation of Echovirus A Particles

Picornavirus infection requires virus uncoating, associated with the production of 135S “A” particles and 80S empty particles from 160S mature virions, to release the RNA genome into the cell cytoplasm. Normal albumin inhibits this process. We now show that when depleted of fatty acids, albumin induces the formation of echovirus A particles.
