Three human protoparvoviruses, bufavirus (BuV), tusavirus (TuV) and cutavirus (CuV), have recently been discovered in diarrheal stool. BuV has associated with diarrhea CuV cutaneous T-cell lymphoma, but there are hardly any data for TuV or stool respiratory samples. Hence, using qPCR IgG enzyme immunoassays, we analyzed 1072 stool, 316 445 serum plasma samples from 1098 patients without gastroenteritis (GE) respiratory-tract infections (RTI) Finland, Latvia Malawi. The overall CuV-DNA...
Human bocaviruses (HBoVs) 1–4 belong to the Parvoviridae family, and they infect respiratory or gastrointestinal tracts in children. We investigated prevalence of HBoV1–4 DNAs blood stool samples, IgG IgM plasma children presenting with acute gastroenteritis (AGE). In addition, we identified HBoV co-infections five most frequent pathogens. A total 83 paired samples were collected from aged years less. Infection markers HBoV1, 2, 3 (viral DNA and/or antibodies) detected 61 out (73.5%)...
: Microvascular flap surgery has become a routine option for defect correction. The role of von Willebrand factor antigen (VWF:Ag) in the pathophysiology complications is not fully understood. We aim to investigate predictive value VWF:Ag microvascular and explore relationship between chronic inflammation VWF:Ag.
Abstract Background Human bocavirus 1 is a commonly detected human parvovirus. Many studies have shown as pathogen in association with acute respiratory tract infections children. However, because persists the upper airways for extensive time periods after infection, definition and diagnostics of infection challenging. Until now, detection exclusively, high viral load samples, viremia been associated clinical picture illness. There are no showing messenger ribonucleic acid peripheral blood...
Human bocavirus (HBoV) is a causative agent of respiratory and gastrointestinal diseases worldwide. Four HBoV species (HBoV1-4) have been identified so far. Although previous report has documented the association with acute gastroenteritis (AGE) in Taiwan, their epidemiology, genetic diversity, phylogenetic relationships remain unclear. In this study, we focused on an investigation these unsolved issues, which will help to reveal molecular epidemiology phylogeny circulating HBoV2 Taiwan. A...
Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a complex multifactorial disease that causes increasing morbidity worldwide, and many individuals with ME/CFS symptoms remain undiagnosed due to the lack of diagnostic biomarkers. Its etiology still unknown, but evidence supports role herpesviruses (including HHV-6A HHV-6B) as potential triggers. Interestingly, infection by these viruses has been reported impact expression microRNAs (miRNAs), short non-coding RNA sequences which...
After primary exposure, the human parvovirus B19 (B19V) genome may remain in central nervous system (CNS), establishing a lifelong latency. The structural characteristics and functions of infected cells are essential for virus to complete its life cycle. Although B19V has been detected brain tissue by sequencing PCR products, little is known about vivo cell tropism pathogenic potential CNS. To detect investigate distribution target CNS, we studied autopsies elderly subjects using molecular...
Meningitis and meningoencephalitis are neurological inflammatory diseases, although routine diagnostics include testing of a wide range pathogens, still in many cases, no causative agent is detected. Human parvovirus B19 (B19V), human bocaviruses 1-4 (HBoV1-4), 4 (hPARV4) members the Parvoviridae family associated with clinical manifestations including disorders. The main aim this study was to determine whether parvoviruses infection markers present among patients...
