Metagenomic approaches to detect viral genomes and variants in clinical samples have various challenges, including low viral titers and bacterial and human genome contamination. To address these limitations, we examined a next-generation sequencing (NGS) and iterative mapping approach for virus detection in clinical samples. We analyzed 40 clinical specimens from hospitalized children diagnosed with acute bronchiolitis, croup, or respiratory tract infections in which virus identification by viral culture or polymerase chain reaction (PCR) was unsuccessful...

Infections of the central nervous system (CNS) are often acute with significant morbidity and mortality. Routine diagnosis of such infections is limited in developing countries and requires modern equipment in advanced laboratories that may be unavailable to a number of patients in sub-Saharan Africa. We developed a TaqMan Array Card (TAC) that detects multiple pathogens simultaneously from cerebrospinal fluid (CSF). The 21-pathogen TAC assays include two parasites (Balamuthia mandrillaris and Acanthamoeba), six bacterial pathogens (Streptococcus pneumoniae, Haemophilus influenzae, Neisseria meningitidis, Mycoplasma pneumoniae, Mycobacterium tuberculosis, and Bartonella) and 13 viruses (parechovirus, dengue, nipah, varicella zoster, mumps, measles, lyssa, herpes simplex virus 1 and 2, Epstein Barr virus, enterovirus, cytomegalovirus and chikungunya)...

BACKGROUND: Central nervous system (CNS) infections require prompt diagnosis, as the clinical condition progresses rapidly and may lead to severe permanent sequelae or death. The causative agents include viruses, bacteria, fungi, and parasites. In this study, samples with the diagnosis of CNS infection based on cerebrospinal fluid (CSF) sent to us from other hospitals/labs, were studied by multiplex real-time Polymerase Chain Reaction (PCR) method. The purpose of this study is to demonstrate, retrospectively, the most common bacteria and viruses causing meningitis and seasonal distribution of these agents using the multiplex real-time PCR method in CSF samples...

Human parechovirus type 3 (HPeV3) can cause serious conditions in neonates, such as sepsis and encephalitis, but data for adults are lacking. The case of a pregnant woman with HPeV3 infection is reported herein. A 28-year-old woman at 36 weeks of pregnancy was admitted because of myalgia and muscle weakness. Her grip strength was 6.0kg for her right hand and 2.5kg for her left hand. The patient's symptoms, probably due to fasciitis and not myositis, improved gradually with conservative treatment, however labor pains with genital bleeding developed unexpectedly 3 days after admission...

Human parechovirus types 1-16 (HPeV1-16) are positive strand RNA viruses in the family Picornaviridae. We investigated a 2015 outbreak of HPeV3 causing illness in infants in Victoria, Australia. Virus genome was extracted from clinical material and isolates and sequenced using a combination of next generation and Sanger sequencing. The HPeV3 outbreak genome was 98.7% similar to the HPeV3 Yamagata 2011 lineage for the region encoding the structural proteins up to nucleotide position 3115, but downstream of that the genome varied from known HPeV sequences with a similarity of 85% or less...

BACKGROUND: Acute encephalitis is a serious neurological condition having a high mortality rate and affecting both children and adults. This study aimed to develop a multiplex PCR method for the simultaneous screening of clinical samples for the presence of the 10 viruses presently considered as the major viral causes of acute encephalitis/ encephalopathy in Asia. METHODS: Using previously published primers that have been widely used to screen for herpes virus-6, influenza A virus, human parechovirus, herpes simplex viruses 1 and 2, Japanese encephalitis virus, group A rotavirus, enterovirus, adenovirus, and dengue virus in clinical samples, a single-tube multiplex PCR assay was developed and was tested for its sensitivity and specificity...

Enteroviruses and human parechoviruses usually cause mild, self-limiting illnesses in children but can occasionally cause severe disease. During 2010-2014, 104 children in the United Kingdom and the Republic of Ireland were admitted to a pediatric intensive care unit with severe enterovirus and human parechovirus infection; 40% had neurologic symptoms, 20% respiratory failure, 16% cardiac complications and 11% septic shock. Annual number of cases and incidence increased in the 5-year period, from 0.6/1000 pediatric intensive care unit admissions (12 cases) in 2010 to 1...

Among infants, almost half of acute liver failure cases are classified as indeterminate, whereas only a small number of cases show a documented viral infection. We present the first reported case of isolated acute hepatic failure in an infant in the setting of a human parechovirus (HPeV) infection. HPeV also may have been contributory to the posttransplant complication of 2 intussusceptions. This is a 10-month-old girl who presented with only symptoms of fussiness and was noted to have progressive decline in synthetic liver function as well as worsening coagulopathy requiring a liver transplant...

To clarify the seroepidemiology of human parechovirus type 1 (HPeV1), 3 and 6, neutralizing antibodies (NT Abs) were measured in 214 serum specimens collected in 2014 in Yamagata, Japan. The seroprevalence against HPeV1 was 100% in all age groups, while that against HPeV3 and HPeV6 was 79.4% and 66.8%, respectively, overall. The geometric mean titers of NT Abs against HPeV1, 3 and 6 were 755.2, 255.0 and 55.9, respectively, overall. Our findings indicate that HPeV1 is the most prevalent HPeV circulating in Yamagata, followed by HPeV3 and HPeV6...

BACKGROUND: Human parechovirus (HPeV) is a genus of virus in the family Picornaviridae, having two species A and B. HPeVs are common infectious agents, usually causing mild diarrhea and respiratory disease in young children. RESULTS: Here, we collected and sequenced the near complete genome sequences of 17 novel HPeVs from children with diarrhea in eastern China, which showed significant nucleotide sequence divergence. Phylogenetic analysis based on the complete genomes of these HPeV strains revealed that they belonged to seven different genotypes (including three putative novel genotypes), suggesting that HPeVs showed genotype diversity in this area...
