Anti-HDV immunoglobulin M testing in hepatitis delta revisited: correlations with disease activity and response to pegylated interferon-alpha 2a treatment
(2012)Background: The role of anti-HDV immunoglobulin M (IgM) testing in patients receiving pegylated interferon-alpha therapy for hepatitis delta is unknown. We performed anti-HDV IgM testing in a well defined cohort of HDVinfected ... -
Applicability of self-obtained urine and vaginal samples for HPV-16,-18,-31 and-45 cervical cancer screening in pregnancy: a pilot cross-sectional study
(2014)Aim:To conduct a pilot cross-sectional study to evaluate the rates of detection of four common high-risk HPV (hr-HPV) types using first-void urine paired with vaginal self-obtained samples in a nonvaccinated population of ... -
Circulation of intergenotype recombinant noroviruses GII.9/GII.6 from 2006 to 2011 in central Greece
(2014)Noroviruses (NoVs) are members of the Caliciviridae family and are recognized as a worldwide cause of acute nonbacterial gastroenteritis. Based on the genetic analysis of the RdRp and capsid regions, human NoVs are divided ... -
Classification and structure of echovirus 5 '-UTR sequences
(2005)Enteroviruses are classified into two genetic clusters on the basis of 5'-UTR and all echoviruses (ECV) are classified together with coxsackie B viruses (CBV), coxsackie A viruses (CAV) types 2-10, 12, 14 and 16, and ... -
Combined 5 ' UTR RFLP analysis and VP1 sequencing for epidemic investigation of enteroviruses
(2013)Enteroviruses, the main cause of aseptic meningitis, consist of 100 serotypes, and many of them have been associated with large outbreaks. In the present study, a comparison of RFLP analysis of the 5' untranslated region ... -
Correlation between recombination junctions and RNA secondary structure elements in poliovirus Sabin strains
(2010)In order to test the hypothesis that RNA structural elements promote the distribution of certain types of recombination junctions in each one of the 2C and 3D poliovirus genomic regions (Sabin 3/Sabin 2 or Sabin 1 in 2C ... -
Diagnostic performance of a rapid in-clinic test for the detection of Canine Parvovirus under different storage conditions and vaccination status
(2015)Canine parvovirus (CPV) is one of the most common causes of acute haemorrhagic enteritis in young dogs, while clinical diagnosis is often indecisive. The aim of our study was to evaluate the diagnostic accuracy of an ... -
Effect of hepatitis C virus on immunological and virological responses in HIV-infected patients initiating highly active antiretroviral therapy: a meta-analysis
(2013)Co-infection of human immunodeficiency virus (HIV) with hepatitis C virus (HCV) is rather common. In the era of highly active antiretroviral therapy (HAART), viral hepatitis could result in adverse outcomes in HIV+ patients. ... -
Evolution of a rare vaccine-derived multirecombinant poliovirus
(2005)Recombination is one of the mechanisms by which viral genomes evolve. A vaccine-derived multirecombinant poliovirus strain was isolated from a 5-month-old child with vaccine-associated paralytic poliomyelitis after oral ... -
Genome analysis of two type 6 echovirus (E6) strains recovered from sewage specimens in Greece in 2006
(2012)Echovirus 6 (E6) is one of the main enteroviral serotypes that was isolated from cases of aseptic meningitis and encephalitis during the last years in Greece. Two E6 (LR51A5 and LR61G3) were isolated from the sewage treatment ... -
Genomic analysis of recombinant Sabin clinical isolates
(2006)Recombination in Poliovirus vaccine strains is a very frequent phenomenon. In this report 23 polio/Sabin strains isolated from healthy vaccinees or from VAPP patients after OPV administration, were investigated in order ... -
Growth kinetic analysis of bi-recombinant poliovirus vaccine strains
(2010)Attenuated strains of Sabin poliovirus vaccine replicate in the human gut and in rare cases may cause vaccine-associated paralytic poliomyelitis (VAPP). Mutations at specific sites of the genome and recombination between ... -
HCV-RNA qualitative assay based on transcription mediated amplification improves the detection of hepatitis C virus infection in patients on hemodialysis: Results from five hemodialysis units in central Greece
(2005)Background: End-stage renal disease patients (ESRD) on maintenance hemodialysis (HD) are at increased risk of acquiring hepatitis C virus (HCV) infection. An early and accurate diagnosis of HCV infection is important for ... -
Identification of novel E6-E7 sequence variants of human papillomavirus 16
(2013)The rate of evolution of the human papillomavirus 16 (HPV16) genome is low. However, the ability of the E6 oncoprotein to interact with distinct p53 variants causes selective pressure on the E6 gene. In addition, intratypic ... -
Impact of HIV Type 1 DNA Levels on Spontaneous Disease Progression: A Meta-Analysis
(2012)Several studies have reported the prognostic strength of HIV-1 DNA with variable results however. The aims of the current study were to estimate more accurately the ability of HIV-1 DNA to predict progression of HIV-1 ... -
Internal translation initiation stimulates expression of the ARF/core+1 open reading frame of HCV genotype 1b
(2011)The hepatitis C virus possesses an alternative open reading frame overlapping the Core gene, whose products are referred to as Core+1 or alternative reading frame (ARF) or F protein(s). Extensive studies on genotype HCV-1 ... -
Laboratory diagnosis of contagious ecthyma: Comparison of different PCR protocols with virus isolation in cell culture
(2006)A new polymerase chain reaction (PCR) assay for rapid diagnosis of contagious ecthyma was designed and applied to 21 clinical samples from Greece. This assay, which detects a highly conserved gene from the parapox genome, ... -
Long-term respiratory follow-up of H1N1 infection
