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)
Thirteen orf virus isolates obtained during the time period between 1995 and 2004 from crusted scab lesions of nine sheep and four goats from different geographical areas of Greece and Italy with suspected contagious ecthyma infection were analyzed. DNA of all isolates was successfully amplified by PCR with the primers 045F-045R and identified them as(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)
The combination of preventive vaccination and diagnostic typing of viral isolates from patients with clinical poliomyelitis constitutes our main protective shield against polioviruses. The restriction fragment length polymorphism (RFLP) adaptation of the reverse transcriptase (RT)-PCR methodology has advanced diagnostic genotyping of polioviruses, although(More)
An outbreak of aseptic meningitis was recorded in Greece during the year 2001. Detection of the clinical strains was achieved by performing reverse transcription-polymerase chain reaction (RT-PCR) on RNA isolated from cell cultures inoculated with treated faecal material from the patients. Serotypic identification of the isolates with mixed equine antisera(More)
The genetic properties of strain K/2002, isolated from fecal samples of a 7-month-old child who had received his first oral poliovirus vaccine (OPV) dose at the age of 3 months, are described. Preliminary sequencing characterization of isolate K/2002 revealed an S3/S2 recombination event at the 3' end of the VP1 coding region. A recombination event resulted(More)
Echovirus 3 (E3) serotype has been related with several neurologic diseases, although it constitutes one of the rarely isolated serotypes, with no report of epidemics in Europe. The aim of the present study was to provide insights into the molecular epidemiology and evolution of this enterovirus serotype, while an E3 strain was isolated from sewage in(More)
The sequences from a large part of the 5'-UTR of 21 coxsackie A virus (CAV) reference strains for which such data did not exist in the past were obtained. Those sequences, along with the respective available sequences from the rest of the CAV reference strains and many other enteroviruses, were compared. According to the results of this comparison,(More)
An immunocapture (IC) ELISA and reverse transcriptase (RT)-PCR assays were evaluated as screening methods for the detection of influenza virus types A and B in clinical samples collected from individuals presenting with influenza-like symptoms in Southern Greece. Standard virus isolation in embryonated hens' eggs was taken as the reference method. According(More)
