Human parechovirus 3 and neonatal infections.

ABSTRACT: A third serotype of human parechovirus (HPeV) has been recently isolated from stool specimens of a young Japanese child with transient paralysis. We report 3 additional cases of neonatal sepsis caused by HPeV-3 in the fall of 2001 in Canadian infants 7-27 days old. All children were hospitalized with high fever, erythematous rash, and tachypnea for a median of 5 days. The viruses isolated from nasopharyngeal aspirates grew slowly on tertiary monkey kidney cells and were successfully passaged on Vero cells. The predicted amino acid identity of the VP0-VP3-VP1 region of the three viruses was 74.6%-74.8%, 73.4%-73.6%, and 97.0%-97.1% when compared to HPeV-1, -2, and -3 prototype strains, respectively. Although different, our isolates were closely related; amino acid identity was 99.6%-100% for the last 3 proteins.

Human parechovirus infections in monkeys with diarrhea, China.

Project description:Information about human parechovirus (HPeV) infection in animals is scant. Using 5' untranslated region reverse transcription-PCR, we detected HPeV in feces of monkeys with diarrhea and sequenced the complete genome of 1 isolate (SH6). Monkeys may serve as reservoirs for zoonotic HPeV transmissions and as models for studies of HPeV pathogenesis.

Epidemiology and clinical associations of human parechovirus respiratory infections.

Project description:Infections with human parechoviruses (HPeVs) are prevalent in young children and have been associated with mild gastroenteritis and, less frequently, with meningitis and neonatal sepsis. To investigate the involvement of these viruses in respiratory disease, a highly sensitive nested PCR was used to screen a large archive of respiratory specimens, collected between January and December 2007. Respiratory samples had previously been tested for eight respiratory viruses, including respiratory syncytial virus and adenovirus, by PCR. HPeV was detected in 34 of 3,844 specimens, representing 27 of 2,220 study subjects (1.2%). HPeV types were identified by sequencing the VP3/VP1 junction amplified by PCR directly from clinical specimens. The assay could amplify all HPeV types examined with high sensitivity (types 1 and 3 to 6) and also identified HPeV types in all but one of the screen-positive study specimens (25 HPeV1 and eight HPeV6 specimens). Infections with both HPeV1 and HPeV6 were seasonal, with highest frequencies in July and August, and restricted to children aged between 6 months and 5 years. Other respiratory viruses were frequently codetected in HPeV-positive specimens, with significant overrepresentation of adenovirus coinfections (37%). Most HPeV-positive specimens were referred from emergency departments, although no association with specific respiratory symptoms or disease was found. In summary, the low frequency of detection and lack of clear disease associations indicate that HPeV1 and -6 are not major pathogens in individuals presenting with respiratory disease. However, the screening and typing methods developed will be of value in further HPeV testing, including testing for meningitis cases and other suspected HPeV-associated disease presentations.

Human parechovirus types 1, 2 and 3 infections in Canada.

Project description:A new reverse transcription-polymerase chain reaction assay was developed for identification of 28 Canadian human parechovirus (HPeV) isolates, including 20 HPeV-1, 3 HPeV-2, and 5 HPeV-3, recovered from 1985 to 2004. All HPeV-1 isolates but 1 were genetically distinct from the Harris reference strain. One HPeV-2 isolate was related to the Williamson strain; the other 2 were related to the Connecticut strain. HPeV-3 isolates clustered together. Seventy-five percent of isolates were recovered during the typical enterovirus season. All patients but 1 were children with a mean age of 14.6 months, 6.3 months, and 0.7 months for HPeV-1, HPeV-2, and HPeV-3 patients, respectively. All HPeV-2- and HPeV-3-infected children were hospitalized with a diagnosis of viremia or sepsis. HPeV-1- infected children had bronchiolitis diagnosed in 50% of the cases, with few cases of pneumonia and enteritis. Two infected patients (1 child with leukemia and a 78-year-old woman) died of septic shock and severe pneumonia, respectively.

Human parechovirus infections in patients admitted to hospital in Northern Italy, 2008-2010.

Project description:Human parechoviruses (HPeVs) infection is associated with a wide range of clinical syndromes such as respiratory, gastrointestinal, neurologic diseases, and neonatal sepsis-like illness. The main objective of this study was to investigate the epidemiology of HPeVs infection in hospitalized patients in a period of 2 years. Respiratory samples from 3,525 patients with respiratory syndrome, cerebrospinal fluid (CSF) from 340 patients with neurologic syndrome as well as CSF and plasma samples from five neonatal patients with sepsis-like illness collected from October 2008 to 2010 were tested retrospectively using HPeV-specific real-time RT-PCR. Phylogenetic analysis of VP3/VP1 region was performed on the positive samples. Fourteen out of 3,525 (0.4%) patients with respiratory syndrome and five out of five patients with sepsis-like illness were positive for HPeV. In 3/5 patients with sepsis-like illness multiple samples (e.g., stool, plasma, CSF, or respiratory samples) were available, and HPeV was found in all specimens. In contrast, no positive CSF was detected among the 340 patients with neurologic syndromes. Eleven patients (57.9%) were infected with HPeV1 strain, 7 (36.8%) with HPeV3, and 1 (5.3%) with HPeV6 strains. Ten of the 14 HPeV patients with respiratory syndrome were co-infected with other respiratory viruses (eight with rhinovirus and two with coronavirus OC43). All five patients with sepsis-like illness were less than 1 month of age and were infected with HPeV3. Although not circulating at high frequency and unlikely to cause respiratory syndrome, HPeV was associated with severe clinical syndromes in a minority of newborns.

Human parechovirus infection, Denmark.

Project description:Human parechoviruses (HPeVs) often cause severe illness among young children. National surveillance with routine testing of all cerebrospinal fluid, fecal, and tissue samples was conducted during January 2009-December 2012 in all counties in Denmark (6,817 samples from 4,804 children were screened for HPeV). We detected HPeV RNA in 202 (3.0%) specimens from 149 persons. Young infants were at highest risk for HPeV, and 9 (6%) of the HPeV-infected children died, probably of their HPeV illness. HPeV3 was the most common genotype identified, and 5 closely related clades of HPeV3 circulated in Denmark throughout the study period. Our study adds perspective on the prevalence and clinical and molecular virologic characteristics of HPeV infection.

Fourth human parechovirus serotype.

Project description:We identified a novel human parechovirus (HPeV) type (K251176-02) from a neonate with fever. Analysis of the complete genome showed K251176-02 to be a new HPeV genotype. Since K251176-02 could not be neutralized with antibodies against known HPeV serotypes 1-3, it should be classified as a fourth HPeV serotype.

Rooting human parechovirus evolution in time.

Project description:BackgroundThe Picornaviridae family contains a number of important pathogenic viruses, among which the recently reclassified human parechoviruses (HPeVs). These viruses are widespread and can be grouped in several types. Understanding the evolutionary history of HPeV could answer questions such as how long the circulating lineages last shared a common ancestor and how the evolution of this viral species is shaped by its population dynamics. Using both strict and relaxed clock Bayesian phylogenetics we investigated 1) the substitutions rates of the structural P1 and capsid VP1 regions and 2) evolutionary timescale of currently circulating HPeV lineages.ResultsOur estimates reveal that human parechoviruses exhibit high substitution rates for both structural P1 and capsid VP1 regions, respectively 2.21 x 10(-3) (0.48 - 4.21 x 10(-3)) and 2.79 x 10(-3) (2.05 - 3.66 x 10(-3)) substitutions per site per year. These are within the range estimated for other picornaviruses. By employing a constant population size coalescent prior, the date of the most recent common ancestor was estimated to be at around 1600 (1427-1733). In addition, by looking at the frequency of synonymous and non-synonymous substitutions within the VP1 gene we show that purifying selection constitutes the dominating evolutionary force leading to strong amino acid conservation.ConclusionIn conclusion, our estimates provide a timescale for the evolution of HPeVs and suggest that genetic diversity of current circulating HPeV types has arisen about 400 years ago.
