Human parechovirus type 1, 3, 4, 5, and 6 detection in picornavirus cultures.
نویسندگان
چکیده
Picornavirus cultures that could not be typed in neutralization assays were analyzed by VP1 reverse transcription-PCR (RT-PCR) and a virus discovery tool (VIDISCA). Human parechoviruses (HPeVs) were frequently identified, among which were the uncommon isolates HPeV-4, HPeV-5, and HPeV-6. The HPeV-5 isolate could be amplified only by VIDISCA and not by VP1 RT-PCR.

Interaction of V 3 and V 6 Integrins with Human Parechovirus 1
Human parechovirus (HPEV) infections are very common in early childhood and can be severe in neonates. It has been shown that integrins are important for cellular infectivity of HPEV1 through experiments using peptide blocking assays and function-blocking antibodies to V integrins. The interaction of HPEV1 with V integrins is presumably mediated by a C-terminal RGD motif in the capsid protein V...
متن کاملNosocomial Outbreak of Parechovirus 3 Infection among Newborns, Austria, 2014
In 2014, sepsis-like illness affected 9 full-term newborns in 1 hospital in Austria. Although results of initial microbiological testing were negative, electron microscopy identified picornavirus. Archived serum samples and feces obtained after discharge were positive by PCR for human parechovirus 3. This infection should be included in differential diagnoses of sepsis-like illness in newborns.
متن کاملInfant deaths associated with human parechovirus infection in Wisconsin.
BACKGROUND From December 1987 through August 2004, lung tissue, nasopharyngeal swabs, and colon swab specimens obtained during 1263 autopsies of infants and young children were examined to assess the role of viruses in deaths of children aged <2 years. METHODS Multiple cell cultures were used to isolate viruses. With 4 exceptions, virus isolates were identified by neutralization, immunofluore...
متن کاملGenome Sequence of Novel Human Parechovirus Type 17
Human parechoviruses (HPeV) circulate worldwide, causing a broad variety of symptoms, preferentially in early childhood. We report here the nearly complete genome sequence of a novel HPeV type, consisting of 7,062 nucleotides and encoding 2,179 amino acids. M36/CI/2014 was taxonomically classified as HPeV-17 by the picornavirus study group.
متن کاملMolecular detection of proteolytic activity of human parechovirus 2A protein by gene expression
Parechoviruses form one of the nine genera in the picornaviridae family, and include two human pathogens: Human parechovirus type1 and 2 (Hpev1 and Hpev2). The genome of picornaviruses encodes a single polyprotein, which undergoes a cleavage cascade performed by virus encoded proteases to give the final virus proteins. The primary cleavage occurs by 2A protein and this step is critical for vi...
