Parechovirus A3 (Par-A3, formerly human parechovirus 3) is an emerging viral infection of the central nervous system in children. We used an automated, homogeneous, cell based assay to identify itraconazole and posaconazole as inhibitors of Par-A3, with antiviral activity below concentrations clinically attainable in pediatric patients. Currently, there is no approved antiviral treatment for Par-A3 infection, despite numerous reports of serious Par-A3 disease in neonates and infants.

Human parechovirus (HPeV) is increasingly being recognized as a potentially severe viral infection in neonates and young infants. HPeV belongs to the family Picornaviridae and is currently divided into 19 genotypes. HPeV-1 is the most prevalent genotype and most commonly causes gastrointestinal and respiratory disease. HPeV-3 is clinically the most important genotype due to its association with severe disease in younger infants, which may partly be explained by its distinct virological properties. In young infants, the typical clinical presentation includes fever, severe irritability, and rash, often leading to descriptions of "hot, red, angry babies...

BACKGROUND: The aim of this study was to investigate whether the syndrome New Neonatal Porcine Diarrhoea Syndrome (NNPDS) is associated with a viral aetiology. Four well-managed herds experiencing neonatal diarrhoea and suspected to be affected by NNPDS were included in a case-control set up. A total of 989 piglets were clinically examined on a daily basis. Samples from diarrhoeic and non-diarrhoeic piglets at the age of three to seven days were selected for extensive virological examination using specific real time polymerase chain reactions (qPCRs) and general virus detection methods...

Besides the influenza virus (IV), several other viruses are responsible for influenza-like illness (ILI). Although human parechoviruses (HPeVs) and enteroviruses (EVs) may impact on ILI, limited data on their epidemiological characteristics are available. During seven consecutive winter seasons (from 2010-2011 to 2016-2017), within the framework of an influenza surveillance system (InfluNet), 593 respiratory swabs were collected from children ≤5 years of age with ILIs. Molecular detection showed that 58...

Human parechovirus 3 (HPeV3), a member of the Picornavirus family, is frequently detected worldwide. However, the observed seropositivity rates for HPeV3 neutralizing antibodies (nAbs) vary from high in Japan to low in the Netherlands and Finland. To study if this can be explained by technical differences or antigenic diversity among HPeV3 strains included in the serological studies, we determined the neutralizing activity of Japanese and Dutch intravenous immunoglobulin batches (IVIG), a rabbit HPeV3 hyperimmune polyclonal serum, and a human HPeV3-specific monoclonal antibody (mAb) AT12-015, against the HPeV3 A308/99 prototype strain and clinical isolates from Japan, the Netherlands and Australia, collected between 1989 and 2015...

Hand, foot and mouth disease (HFMD) and herpangina (HA) are common childhood diseases mostly associated with human enteroviruses (EV). Although usually benign illnesses, neurological complications may be observed during large epidemics when enterovirus A71 (EV-A71) is involved, as observed in the Asia Pacific Region and in China since the late 1990s. The occurrence of these complications warrants reinforcing the surveillance of the emergence of EV-A71 infections in France and Europe. Monitoring EV infections associated with HFMD can be considered as an effective tool to detect an upsurge of EV-A71 infections in a timely manner...

Enterovirus (EV) and human parechovirus (HPeV) are major causes of sepsis-like illness in infants under 90 days of age and have been identified as neurotropic. Studies about acute and long-term neurodevelopment in infants with sepsis-like illness without the need for intensive care are few. This study investigates cerebral imaging and neurodevelopmental outcome following EV and HPeV infection in these infants. We studied infants under 90 days of age who were admitted to a medium care unit with proven EV- or HPeV-induced sepsis-like illness...

The first human parechovirus 3 (HPeV3 VGHKS-2007) in Taiwan was identified from a clinical specimen from a male infant. The entire genome of the HPeV3 isolate was sequenced and compared to known HPeV3 sequences. Genome alignment data showed that HPeV3 VGHKS-2007 shares the highest nucleotide identity, 99%, with the Japanese strain of HPeV3 1361K-162589-Yamagata-2008. All HPeV3 isolates possess at least 97% amino acid identity. The analysis of the genome sequence of HPeV3 VGHKS-2007 will facilitate future investigations of the epidemiology and pathogenicity of HPeV3 infection...

Ljungan and Sebokele viruses are thought to be rodent-borne (picorna)viruses in the genus Parechovirus. Using random amplification and next generation sequencing method a novel Ljungan/Sebokele-like picornavirus was identified in birds of prey. Viral RNA was detected in total of 1 (9%) of the 11 and 2 (28.6%) of the 7 faecal samples from common kestrels and red-footed falcons in Hungary, respectively. High faecal viral RNA load (4.77×10(6) genomic copies/ml) measured by qPCR. The complete genome of picornavirus strain falcon/HA18_080/2014/HUN (KY645497) is 7964-nucleotide (nt) long including a 867-nt 5'end and a 101-nt 3'end (excluding the poly(A)-tail)...

The infectious etiology of myocarditis often remains unidentified. We report a case of myocarditis associated with human parechovirus (HPeV) infection in an adult. HPeV is an emerging pathogen that can cause serious illness, including myocarditis, in adults. Testing for HPeV should be considered in differential diagnosis of myocarditis.

Viruses have long been considered potential triggers of autoimmune diseases. Here we defined the intestinal virome from birth to the development of autoimmunity in children at risk for type 1 diabetes (T1D). A total of 220 virus-enriched preparations from serially collected fecal samples from 11 children (cases) who developed serum autoantibodies associated with T1D (of whom five developed clinical T1D) were compared with samples from controls. Intestinal viromes of case subjects were less diverse than those of controls...
