Considerable time and effort can be saved by simultaneously amplifying multiple sequences in a single reaction, a process referred to as multiplex polymerase chain reaction (PCR). Multiplex PCR requires that primers lead to amplification of unique regions of DNA, both in individual pairs and in combinations of many primers, under a single set of reaction(More)
A simple, rapid and specific diagnostic polymerase chain reaction (PCR) method was developed for sheep poxvirus identification. The primers used were from the sequenced genomes of the capripox viruses KS-1 and InS-1. Six different sheep pox isolates were tested against two orf (parapox) and three animal herpesviruses as controls. Material from uninfected(More)
A seasonal distribution of enteroviruses and adenoviruses in raw sewage effluents of Athens, Greece, was observed over a 15-month surveillance period. All 36 samples tested were positive for both virus groups. Adenovirus concentration levels ranged from 70 to 3200 cytopathic units per litre of sample, whereas the corresponding values for enteroviruses were(More)
Multiplex polymerase chain reaction (PCR) is a variant of PCR in which two or more target sequences are simultaneously amplified in the same reaction. In the present study we investigated the limits to which the duration of multiplex PCR steps can be shortened using the thermal cycler Gene Amp PCR system 9600 (Perkin Elmer, Oak Brook, IL). The present(More)
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, was evaluated for its sensitivity and specificity in order to be considered as a useful diagnostic tool. A comparative study with two(More)
Two enteroviruses from river water and four from sewage treatment plant were isolated in Larissa, Greece, that all shared the same sequence. A full genome analysis was conducted in an attempt to reveal the evolutionary pathways of one of the isolated strains (LR11F7). VP1 nucleotide and phylogenetic analysis revealed that the isolated strain had 78%(More)
In this study we compared the identification results of 41 echovirus clinical isolates using RIVM pools (National Institute for Public Health and the Environment RIVM, Bilthoven, The Netherlands) and reverse transcription-polymerase chain reaction (PCR) assays. Primer pair UG52-UC53 amplified a 433-bp segment in the 5' untranslated region. Restriction(More)
The E2 gene of human papilloma virus is expressed at the early stage of the viral life cycle, encoding the E2 transcription factor, and regulates the expression of E6 and E7 oncogenes. Disruption of E2 gene due to viral integration inhibits the transcriptional suppression of the HPV oncogenes, inducing cell proliferation. In the present study, a total of 22(More)
The 3D region of 46 clinical Coxsackievirus strains, primarily belonging to the human enterovirus B species (HEV-B), were analyzed using nucleotide distance matrices and phylogeny software. The conclusions from previously analyzed genomic regions (VP1-2A-2B-2C) of the aforementioned strains revealed that enteroviruses' inheritance is being guided by gene(More)
The HPV16 E1∧E4 protein is thought to contribute to the release of newly formed viral particles from infected epithelia. In order to investigate amino acid mutations in the HPV16 E1∧E4 protein, the complete E4 ORF was amplified by PCR in 27 HPV16-positive cervical samples, and the amplicons were cloned. Fifteen nucleic acid variations were identified in the(More)
