Abstract
Saffold virus (SAFV) and human cosavirus (HCoSV) are emerging viruses of the Picornaviridae family. They have been shown to associate with gastrointestinal infection and more recently these viruses have also been demonstrated to associate with other clinical infections such as the respiratory tract, cardiovascular system, and the cerebral ventricular system. In this study, 2459 stool specimens collected from pediatric patients admitted to hospitals with acute gastroenteritis from January 2017 to December 2022, were screened for SAFV and HCoSV utilizing reverse transcription-polymerase chain reaction. Positive samples were then characterized into genotypes via nucleotide sequencing and bioinformatic analysis. Of the 2459 samples, 21 and 39 were positive for SAFV (0.9%) and HCoSV (1.6%), respectively. Three genotypes of SAFV were identified-SAFV-1 (38%), SAFV-2 (24%), and SAFV-3 (38%). Two genetic groups of HCoSV were identified-HCoSV-C (97%) and HCoSV-A (3%), demonstrating a large increase of HCoSV-C as compared to those reported previously from the same geographical region in Thailand. This study provides the prevalence of SAFV and HCoSV genotypes in Chiang Mai, Thailand during a period of 6 years from 2017 to 2022.

[PMID: 35096871 PMCID: PMC8792846 DOI: 10.3389/fmed.2021.775698] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2021] [Accepted: 10/29/2021] [Indexed: 01/20/2023] Open
Abstract
Background: Bufavirus (BuV), Human Cosavirus (HCoSV), and Saffold (SAFV) virus are three newly discovered viruses and have been suggested as possible causes of gastroenteritis (GE) in some studies. The aim of the present study was to estimate the overall prevalence of viruses and their association with GE. Methods: A comprehensive systematic search was conducted in Scopus, Web of Science, PubMed, and Google scholar between 2007 and 2021 to find studies on the prevalence of BuV, HCoSV, and SAFV viruses. Result: Meta-analysis of the 46 included studies showed the low prevalence of BuV (1.%, 95% CI 0.6-1.5%), HCoSV (0.8%, 95% CI 0.4-1.5%), and SAFV (1.9%, 95% CI 1.1-3.1%) worldwide. Also, no significant association between these viruses and GE was observed. BuV was isolated from patients with GE in Africa, while SAFV was more common in Europe. BuV1 and BuV2 have the same prevalence between the three identified genotypes of BuV. HCoSV-C was the most prevalent genotype of HCoSV, and SAFV2 was the commonest genotype of SAFV. All of these viruses were more prevalent in children older than 5 years of age. Conclusion: This was the first meta-analysis on the prevalence and association of BuV, HCoSV, and SAFV with GE. While no significant association was found between infection with these viruses and GE, we suggest more studies, especially with case-control design and from different geographical regions in order to enhance our knowledge of these viruses.

Abstract
Rotavirus vaccines (RVVs) have substantially diminished mortality from severe rotavirus (RV) gastroenteritis but are significantly less effective in low- and middle-income countries (LMICs), limiting their life-saving potential. The etiology of RVV’s diminished effectiveness remains incompletely understood, but the enteric microbiota has been implicated in modulating immunity to RVVs. Here, we analyze the enteric microbiota in a longitudinal cohort of 122 Ghanaian infants, evaluated over the course of 3 Rotarix vaccinations between 6 and 15 weeks of age, to assess whether bacterial and viral populations are distinct between non-seroconverted and seroconverted infants. We identify bacterial taxa including Streptococcus and a poorly classified taxon in Enterobacteriaceae as positively correlating with seroconversion. In contrast, both bacteriophage diversity and detection of Enterovirus B and multiple novel cosaviruses are negatively associated with RVV seroconversion. These findings suggest that virome-RVV interference is an underappreciated cause of poor vaccine performance in LMICs. Longitudinal analysis of microbiota of Ghanaian infants receiving rotavirus vaccine Streptococcus and Enterobacteriaceae taxa positively associate with RVV seroconversion Enterovirus B, Cosavirus A, and phage richness negatively associate with RVV serostatus

Abstract
OBJECTIVE Human cosavirus (HCosV) is a newly recognized virus that seems to be partly related to nonpolio flaccid paralysis and acute gastroenteritis in pediatric patients. However, the relationship between HCosV and diseases in humans is unclear. To assess an investigation for the occurrence of HCosV among pediatric patients involved in meningitis and encephalitis, we implemented a real-time quantitative polymerase chain reaction assay for detection and quantification of HCosV in stool specimens. MATERIALS AND METHODS In this study, a total of 160 cerebrospinal fluid samples from September 2019 to October 2020 were collected from presenting pediatric patients with meningitis and encephalitis in a Karaj hospital, Iran. After viral RNA extraction, the real-time quantitative polymerase chain reaction was performed to amplify the 5'Un-Translated Region region of the HCosV genome and viral load was analyzed. RESULTS Of the 160 samples tested, the HCosV genomic RNA was detected in 2/160 (1.25%) of samples. The minimum viral load of HCosV was 3.5 × 103 copies/mL from 4 years male patient. The maximum viral load was determined to be 2.4 × 105 copies/mL in one sample obtained from 3.5 years female patient. CONCLUSIONS This is the first documentation of HCosV detection in cerebrospinal fluid samples that better demonstrates relation of HCosV with neurologic diseases including meningitis and encephalitis. Also, these results indicate that HCosV has been circulating among Iranian pediatric patients.

FOOD AND ENVIRONMENTAL VIROLOGY 2021; 13:64-73. [PMID: 33165867 DOI: 10.1007/s12560-020-09451-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/13/2020] [Accepted: 11/04/2020] [Indexed: 06/11/2023]
Abstract
Cosaviruses (CoSV) and Saffold cardiovirus (SAFV) are novel members of the Picornaviridae family. The Matanza-Riachuelo river basin covers a total area of 2200 km2 with approximately 60 km long. Its last section is called Riachuelo River. The aim of this study was to describe the circulation of both picornaviruses and their relationship with the environmental situation of the Riachuelo River using 274 samples collected from 2005 to 2015. CoSV and SAFV were investigated in samples available by two periods: 2005-2006 and 2014-2015 (103 and 101, respectively). Physicochemical and bacteriological parameters confirmed very high levels of human fecal contamination during the 11 years evaluated. CoSV was detected in 85.7% (66/77) and 65.4% (17/26) of the samples collected in 2005-2006 and 2014-2015 periods, respectively. Species A and D were identified, the first one being widely predominant: 74.1% (20/27) and 75.0% (3/4) in both periods. SAFV virus was detected in 47.1% (32/68) and 52.6% (10/19) in periods 2005-2006 and 2014-2015, respectively. SAFV-6 was the most identified genotype in the entire study, while SAFV-3 was predominant in 2005-2006. The contribution of genotypes 1, 2, 4 and 8 was minor. The high prevalence of CoSV and SAFV suggests that both viruses have been circulating in Argentina at least since 2005. Our results show that a watercourse with high rates of human fecal contamination can become a persistent source of new viruses which capacity to produce human diseases is unknown.

Molecular detection of cosaviruses in a patient with acute flaccid paralysis and in sewage samples in Germany. Virus Res 2021; 297:198285. [PMID: 33548413 DOI: 10.1016/j.virusres.2020.198285] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2020] [Revised: 12/02/2020] [Accepted: 12/28/2020] [Indexed: 12/18/2022]
Abstract
Cosaviruses (CoSV) were first identified in stool samples collected from non-polio acute flaccid paralysis (AFP) cases and their healthy contacts in Pakistan in 2003. The clinical importance of CoSV remains unclear as data on epidemiology are scarce and no routine diagnostic testing is done. In this study, we characterized human CoSV (HCoSV) in a child with non-polio AFP and in sewage samples collected in Berlin, Germany. Using unbiased high-throughput sequencing and specific PCR, we characterized a HCoSV-D in stool samples of a three-year-old child hospitalized in Germany with non-polio AFP and travel history to Pakistan. The shedding pattern and absence of other relevant pathogens suggests that HCoSV-D may have been involved in the genesis of AFP. The HCoSV-RNA concentration was high, with 2.57 × 106 copies per mL fecal/suspension, decreasing in follow-up samples. To investigate the possibility of local circulation of HCoSV, we screened Berlin sewage samples collected between 2013 and 2018. Molecular testing of sewage samples has shown the presence of CoSV in several parts of the world, but until now not in Germany. Of our sewage samples, 54.3 % were positive for CoSV, with up to three viral species identified in samples. Phylogenetically, the German sequences clustered intermixed with sequences obtained globally. Together, these findings emphasize the need for further clinical, epidemiological, environmental, pathogenicity and phylogenetic studies of HCoSV.

Abstract
Acute gastroenteritis (AG) is responsible for 525,000 deaths worldwide in children under-5-years and is caused by the Human Cosavirus (HCoSV; family Picornaviridae, Genus Cosavirus). Although its health importance, a significant percentage of diarrhea cases (≈ 40 %) still of unknown etiology. In Brazil, few studies have reported HCoSV-A sequences analyzing partial 5' UTR. This study characterized the first near-complete genome of a Cosavirus A (strain AM326) from a child hospitalized with AG in Amazonas state, Northern Brazil. High throughput sequencing (HTS) was performed using the HiSeq™ 2500 platform (Illumina) in one fecal specimen collected from the Surveillance of Rotavirus Network of the Evandro Chagas Institute collected in 2017. Sequence reads were assembled by the De Novo approach using three distinct algorithmic (IDBA-UD, Spades, and MegaHit). The final contig was recovered from the HCoSV-AM326 sample revealing 7,735 nt in length (SRA number SRR12535029; GenBank MT023104) and the genetic characterization, as well as phylogenetic analysis demonstrated a new variant strain from Brazil, highlighting the association of HCoSV-A as a possible causative agent of AG. This finding demonstrates the importance of the metagenomic approach to elucidate cases of diarrhea without a defined etiology, as well as providing a better understanding about the virus genetics, evolution and epidemiology.

Abstract
Human Cosaviruses (HCoSVs) are relatively newly characterized picornaviruses; they have been described in non-polio acute flaccid paralysis, diarrheal patients, and healthy individuals. Previous studies showed HCoSV circulation in Tunisia and only six genotypes circulating in the country were reported. In the present study, we sequenced 27 complete VP1 genomic region from HCoSV isolates in human feces from healthy individuals and patients with acute flaccid paralysis in Tunisia. Most of the Tunisian sequences belong to species A (78%, 21 out of 27). Three sequences belong to species B, two to species E and one sequence to species D. The Tunisian sequences belonged to genotype A6, A7, A8, A10, A1, A17 and E2. Based on genetic distance criteria for assigning genotypes corresponding to neutralization serotypes in enteroviruses we also identified 4 new HCoSV genotypes named A25, B2, B3 and D6. Our study updates the genetic classification of HCoSVs, proposes new genotypes within species A, B and D and contributes to a better knowledge of the HCoSV circulation throughout the world.

Abstract
BACKGROUND Human cosaviruses (HCoSVs) are newly discovered enteric viruses in the Picornaviridae family. They have been described in non-polio acute flaccid paralysis, diarrheal patients, and healthy individuals. They remain rarely documented in immunodeficient patients. OBJECTIVES This study reports iterative excretion of HCoSVs in a patient with major histocompatibility complex (MHC) class II combined immunodeficiency, a relatively common primary immunodeficiency in consanguineous settings. METHODS A total of 35 samples were collected from a patient followed for oral polio vaccine strains detection in stool samples during a 57-month period. Detection of HCoSVs in stools was performed by nested RT-PCR in the 5' noncoding region. The genotype identification and screening for recombinant strains was performed by sequencing in the VP1 and 3D genomic regions followed by phylogenetic analysis. RESULTS The patient was infected with HCoSVs twice at a 3-year interval. The excreted viruses belonged to 2 different genotypes with 2 probable recombinant viruses. During HCoSV infections, the patient was also excreting Sabin-related polioviruses. CONCLUSIONS This study describes excretion kinetics and genetic characteristics of HCoSVs in a patient with combined immunodeficiency due to MHC class II expression defect. The patient did not have concomitant symptoms related to the HCoSV infection.

Abstract
In the present article we report the nearly full length genome of a Cosavirus strain (BRTO-83) isolated from a child with acute gastroenteritis, and who is an inhabitant of a rural area in the central region of Brazil. The sample was previously screened and negative for both: common enteric viruses (i.e. rotavirus and norovirus), bacteria, endoparasites and helminthes. Evolutionary analysis and phylogenetic inferences indicated that the Brazilian BRTO-83 Cosavirus strain was a recombinant virus highly related to the E/D recombinant NG385 strain (Genbank JN867757), which was isolated in Nigeria from an acute flaccid paralysis patient. This is the first report of a recombinant E/D Cosavirus strain detected in Brazil, and the second genome described worldwide. Further surveillance and molecular studies are required to fully understand the epidemiology, distribution and evolution of the Cosavirus.
