WU Polyomavirus Infection in Children With Acute Lower Respiratory Tract Infections in China, 2017 to 2019: Case Reports and Multicentre Epidemiological Survey. Front Cell Infect Microbiol 2022; 11:835946. [PMID: 35360221 PMCID: PMC8963484 DOI: 10.3389/fcimb.2021.835946] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2021] [Accepted: 12/24/2021] [Indexed: 11/13/2022] Open
Abstract
WU polyomavirus (WUPyV) is a novel member of the family Polyomaviridae recently detected in respiratory tract specimens. So far, it has not been proven whether WUPyV is a real causative agent for respiratory diseases. In this study, we described two patients with fatal infection who had WUPyV detected in their nasopharyngeal swabs. Furthermore, we conducted a multicentre study in six hospitals from different districts of China. WUPyV was detected by real-time polymerase chain reaction assays, and the clinical and molecular epidemiological characteristics of WUPyV strains among hospitalized children with acute lower respiratory tract infections all around China from 2017 to 2019 were analysed. Two complete WUPyV genome sequences were assembled from fatal patients’ airway specimens. Phylogenetic tree analysis revealed that they were most closely related to strains derived from Fujian and Chongqing, China, in 2008 and 2013, respectively. In 2017–2019, a total of 1,812 samples from children with acute lower respiratory tract infections were detected for WUPyV, of which 11 (0.6%) were positive. Children aged ≤5 were more susceptible to WUPyV infection. A total of 81.8% of WUPyV-positive patients were coinfected with other viruses, of which rhinovirus enjoyed the highest frequency. The main clinical symptoms of infected patients include fever, coughing and sputum expectoration. Most patients were diagnosed with pneumonia, followed by bronchial surgery. Three patients manifested severe infection, and all patients improved and were discharged. Our results show that WUPyV persistently circulates in China. Further investigations on the clinical role and pathogenicity of WUPyV are necessary.

Abstract
BACKGROUND Washington University polyomavirus (WUPyV) is a novel human polyomavirus detected in childwith acute respiratory infection in 2007. However, the relationship between WUPyV and respiratory diseases has yet to be established for lacking of a suitable in vitro culture system. METHODS To isolate WUPyV with human airway epithelial (HAE) cells, the positive samples were incubated in HAE, and then the nucleic acid, VP1 protein and virions were detected using real-time PCR, immunofluorescence and electron microscopy respectively. RESULTS The result showed that WUPyV could replicate effectively in HAE cells and virions with typical polyomavirus characteristics could be observed. Additionally, the entire genome sequence of the isolated strain (BJ0771) was obtained and phylogenetic analysis indicated that BJ0771 belongs to gene cluster I. CONCLUSIONS Our findings demonstrated clinical WUPyV strain was successfully isolated for the first time in the world and this will help unravel the etiology and pathogenic mechanisms of WUPyV in respiratory infection diseases.

Abstract
Polyomaviruses (PyVs) are small DNA viruses that infect several species, including mammals, birds and fishes. Their study gained momentum after the report of previously unidentified viral species in the past decade, and especially, since the description of the first polyomavirus clearly oncogenic for humans. The aim of this work was to review the most relevant aspects of the evolution and molecular epidemiology of polyomaviruses, allowing to reveal general evolutionary patterns and to identify some unaddressed issues and future challenges. The main points analysed included: 1) the species and genera assignation criteria; 2) the hypotheses, mechanisms and timescale of the ancient and recent evolutionary history of polyomaviruses; and 3) the molecular epidemiology of human viruses, with special attention to JC, BK and Merkel cell polyomaviruses.

Abstract
In the last decade, the phylogenetic approach is recurrent in molecular evolutionary analysis. On 12 May, 2019, about 2 296 213 papers are found, but typing "phylogeny" or "epidemiology AND phylogeny" only 199 804 and 20 133 are retrieved, respectively. Molecular epidemiology in infectious diseases is widely used to define the source of infection as so as the ancestral relationships of individuals sampled from a population. Coalescent theory and phylogeographic analysis have had scientific application in several, recent pandemic events, and nosocomial outbreaks. Hepatitis viruses and immunodeficiency virus (human immunodeficiency virus) have been largely studied. Phylogenetic analysis has been recently applied on Polyomaviruses so as in the more recent outbreaks due to different arboviruses type as Zika and chikungunya viruses discovering the source of infection and the geographic spread. Data on sequences isolated by the microorganism are essential to apply the phylogenetic tools and research in the field of infectious disease phylodinamics is growing up. There is the need to apply molecular phylogenetic and evolutionary methods in areas out of infectious diseases, as translational genomics and personalized medicine. Lastly, the application of these tools in vaccine strategy so as in antibiotic and antiviral researchers are encouraged.

Abstract
AIM To study prevalence of Karolinska Institutet (KI) and Washington University (WU) polyomavirus (PyV) in 100 tonsils, 100 adenoids, 146 throat swab and 15 middle ear fluid samples collected from 146 patients (120 children and 26 adults), to analyze the sequence of noncoding control region (NCCR) and complete WUPyV genomes. MATERIALS & METHODS Viruses were detected by quantitative real-time PCR. The NCCRs and WUPyV genomes were sequenced and analyzed. RESULTS The frequency of WUPyV and KIPyV DNA was 27 and 11% in adenoids, 4 and 3% in tonsils, 4.1 and 1.4% in throat swab samples, respectively. The WUPyV DNA was detected in one middle ear fluid sample as well. The WUPyV NCCRs showed mutations which may alter the putative transcription factor binding sites. Phylogenetic analysis revealed three clades of WUPyV. CONCLUSION Tonsils and adenoids might be site of virus replication and/or persistence, and WUPyV may invade into the middle ear.

Abstract
AIM To explore the molecular epidemiology and clinical characteristics of Washington University polyomavirus (WUPyV) infection in pediatric patients with acute respiratory tract infections in China. MATERIALS & METHODS A laboratory surveillance was performed to recruit pediatric patients with acute respiratory tract infections. WUPyV was detected using real-time PCR and complete genome was sequenced for randomly selected positive nasopharyngeal aspirate. RESULTS Altogether 122 (7.5%) of 1617 children found to be infected with WUPyV and 88 (72.1%) were coinfected with other viruses during 2012-2015. The phylogenetic analysis showed that 14 strains from our study formed two new clusters (Id and IIIc) within the Branch I and Branch III, respectively. CONCLUSION WUPyV is persistently circulating in China. Surveillance on WUPyV infection in wider areas and long persistence is warranted.

Abstract
OBJECTIVE To determine Washington University (WU) polyomavirus strains circulating among hospitalized patients with respiratory tract infections (RTI) in Kuwait. MATERIALS AND METHODS Samples from 459 hospitalized children and adult RTI patients were screened for respiratory viruses by polymerase chain reaction from April 2013 to April 2016. The VP2 gene from WU virus (WUV)-positive samples was sequenced and subjected to phylogenetic analysis. RESULTS Of the 459 hospitalized RTI patients, 18 (3.9%) patients were positive for WUV infection. WUV infection was common among children aged ≤11 years (9 patients, 50%). Among the 18 WUV-infected hospitalized patients, viral co-infection was detected in 9 patients (50%). The most common viruses associated with mixed infection were respiratory syncytial virus and human rhinovirus (2 patients, 11.1% each). Of the 18 WUV-infected patients, 4 were sequenced and subjected to phylogenetic analysis. The circulating strains belong to type Ia and IIIb. CONCLUSION This study enabled us to detect WUV among hospitalized RTI patients. Co-infection with other respiratory viruses was notable. Two circulating WUV genotypes (Ia and IIIb) were identified among hospitalized RTI patients in Kuwait.

Abstract
The family Polyomaviridae is comprised of circular double-stranded DNA viruses, several of which are associated with diseases, including cancer, in immunocompromised patients. Here we describe a novel polyomavirus recovered from the fecal microbiota of a child in Malawi, provisionally named STL polyomavirus (STLPyV). We detected STLPyV in clinical stool specimens from USA and The Gambia at up to 1% frequency. Complete genome comparisons of two STLPyV strains demonstrated 5.2% nucleotide divergence. Alternative splicing of the STLPyV early region yielded a unique form of T antigen, which we named 229T, in addition to the expected large and small T antigens. STLPyV has a mosaic genome and shares an ancestral recombinant origin with MWPyV. The discovery of STLPyV highlights a novel alternative splicing strategy and advances our understanding of the complex evolutionary history of polyomaviruses.

Abstract
Approximately 20% of the tumours in humans are associated with contagious viral agents. Merkel cell carcinoma is a rare and highly aggressive tumour which may originate from the epidermal stratum basale, although the origin is still controversial. This tumour is most commonly found in elderly and immunocompromised patients in sun exposed areas, especially in the head and neck regions. Merkel cell carcinoma often causes a diagnostic challenge with a dramatically increasing incidence. In 2008, a DNA tumour virus, a polyomavirus (Merkel cell polyomavirus) was detected in Merkel cell carcinomas, and this finding helped to understand the etiological background of the disease. The infectious - probably viral - etiology resulted in a paradigm shift in pathogenesis and, hopefully, in therapy as well. This review summarizes the current knowledge related to Merkel cell carcinoma and the first oncogenic human polyomavirus, the Merkel cell polyomavirus, to promote the clinical adaptation of the information.

Abstract
We have discovered a novel polyomavirus present in multiple human stool samples. The virus was initially identified by shotgun pyrosequencing of DNA purified from virus-like particles isolated from a stool sample collected from a healthy child from Malawi. We subsequently sequenced the virus' 4,927-bp genome, which has been provisionally named MW polyomavirus (MWPyV). The virus has genomic features characteristic of the family Polyomaviridae but is highly divergent from other members of this family. It is predicted to encode the large T antigen and small T antigen early proteins and the VP1, VP2, and VP3 structural proteins. A real-time PCR assay was designed and used to screen 514 stool samples from children with diarrhea in St. Louis, MO; 12 specimens were positive for MWPyV. Comparison of the whole-genome sequences of the index Malawi case and one St. Louis case demonstrated that the two strains of MWPyV varied by 5.3% at the nucleotide level. The number of polyomaviruses found in the human body continues to grow, raising the question of how many more species have yet to be identified and what roles they play in humans with and without manifest disease.

Abstract
Polyomaviridae is a growing family of naked, double-stranded DNA viruses that infect birds and mammals. The last few years, several new members infecting birds or primates have been discovered, including seven human polyomaviruses: KI, WU, Merkel cell polyomavirus, HPyV6, HPyV7, trichodysplasia spinulosa-associated polyomavirus, and HPyV9. In addition, DNA and antibodies against the monkey lymphotropic polyomavirus have been detected in humans, indicating that this virus can also infect man. However, little is known about the route of infection, transmission, cell tropism, and, with the exception of Merkel cell polyomavirus and trichodysplasia spinulosa-associated polyomavirus, the pathogenicity of these viruses. This review compares the genomes of these emerging human polyomaviruses with previously known polyomaviruses detected in man, reports mutations in different isolates, and predicts structural and functional properties of their viral proteins.

Abstract
This study aimed at investigating the prevalence and clinical characteristics of children with respiratory infection by WU polyomavirus (WUPyV) in Southern China. Nasopharyngeal aspirate samples were collected from 771 children with acute respiratory tract infection admitted to hospital and 82 samples from healthy subjects for routine examination at the outpatient service at the Second Affiliated Hospital of Shantou University, Medical College from July 2008 to June 2009. WUPyV was detected by the polymerase chain reaction (PCR) and DNA sequencing. All WUPyV-positive specimens were characterized further for nine viruses causing common respiratory infections, including influenza A and B, respiratory syncytial virus (RSV), parainfluenza virus (PIV) 1 and 3, human metapneumovirus, human bocavirus, adenovirus, and rhinovirus by PCR or real time (RT)-PCR. Fifteen out of 771 specimens from patients with acute respiratory tract infection, but none from healthy subjects, were positive for WUPyV and the positivity rate was 2%. Patients with WUPyV infection were between 2 and 48 months of age, and nine of the patients were male while six female. Four out of 15 patients were co-infected with RSV, one with adenovirus or rhinovirus, respectively. Patients with WUPyV infection displayed predominantly cough, moderate fever, and wheezing, and were diagnosed with pneumonia (n = 8), bronchiolitis (n = 4), upper respiratory tract infections (n = 2) and bronchitis (n = 1). One patient developed encephalitis. Therefore, WUPyV infection can cause acute respiratory tract infection with atypical symptoms, including severe complications, in children.

Abstract
The oncogenic Merkel cell polyomavirus (MCPyV) infects humans worldwide, but little is known about the occurrence of viruses related to MCPyV in the closest phylogenetic relatives of humans, great apes. We analyzed samples from 30 wild chimpanzees and one captive gorilla and identified two new groups of polyomaviruses (PyVs). These new viruses are by far the closest relatives to MCPyV described to date, providing the first evidence of the natural occurrence of PyVs related to MCPyV in wild great apes. Similar to MCPyV, the prevalence of these viruses is relatively high (>30%). This, together with the fact that humans in West and Central Africa frequently hunt and butcher primates, may point toward further MCPyV-like strains spreading to, or already existing in, our species.
