ABSTRACT Human adenoviruses (HAdV) and human polyomavirus JCPyV have been previously proposed as indicators of fecal viral contamination in the environment. Different wastewater matrices analyzed by applying real-time quantitative PCR procedures for presence, quantity, stability a wide diversity excreted HAdV JCPyV. High quantities were detected sewage, effluent wastewater, sludge, biosolid samples. Both viruses showed high urban sewage. These results confirm suitability both pollution.
ABSTRACT At this time, about 3,000 different viruses are recognized, but metagenomic studies suggest that these a small fraction of the exist in nature. We have explored viral diversity by deep sequencing nucleic acids obtained from virion populations enriched raw sewage. identified 234 known viruses, including 17 infect humans. Plant, insect, and algal as well bacteriophages were also present. These represented 26 taxonomic families included with single-stranded DNA (ssDNA), double-stranded...
ABSTRACT The Adenoviridae and Polyomaviridae families comprise a wide diversity of viruses which may be excreted for long periods in feces or urine. In this study, preliminary analysis the prevalence environment potential usefulness as source-tracking tools human animal adenoviruses polyomaviruses has been developed. Molecular assays based on PCR specifically targeting (HAdV), porcine (PAdV), bovine (BAdV), (BPyV) were applied to environmental samples including urban sewage, slaughterhouse,...
Large numbers of viruses are excreted in human feces and urine, which even at low concentrations may cause illness when ingested. Some these have not been traditionally monitored terms waterborne diseases considered emergent viruses, such as hepatitis E virus (HEV) JC BK polyomavirus (JCPyV BKPyV). The high prevalence adenoviruses (HAdV) polyomaviruses, both show DNA genomes, sewage from widely divergent areas has suggested the relevance evaluating possible indicators viral contamination....
ABSTRACT In this study, a molecular procedure for the detection of adenoviruses animal origin was developed to evaluate level excretion these viruses by swine and cattle design test facilitate tracing specific sources environmental viral contamination. Two sets oligonucleotides were designed, one detect porcine other bovine ovine adenoviruses. The specificity assays assessed in 31 fecal samples 12 sewage that collected monthly during 1-year period. data also provided information on...
The aim of the study was to analyse evolution prevalence HAV and HEV in population eastern Spain by analysing viruses excreted urban sewage. Raw sewage samples were collected analysed during several years using RT-PCR techniques sequencing analysis. Two limiting regions analysed, one them having implemented vaccination programs. Acute symptomatic cases also examined. Results compared with those from previous studies area identical methodology. percentage positive fell 57.4% 3.1% 5–10 two...
Many different viruses are excreted by humans and animals frequently detected in fecal contaminated waters causing public health concerns. Classical bacterial indicator such as E. coli enterococci could fail to predict the risk for waterborne pathogens viruses. Moreover, presence levels of indicators do not always correlate with concentration viruses, especially when these present low concentrations. Our research group has proposed new viral methodologies determining pollution environmental...
This study involved collaboration between three centres with expertise in viruses, bacteria and protozoa. The focus of the research was dissemination removal pathogens faecal indicators two sewage treatment plants (STP1 STP2) using tertiary treatments. Samples were collected over a period five months through processes. Analysis samples revealed that not efficient at removing tested during study. From entry point (raw sewage) to effluent level (tertiary water), experimental results showed...
In this study, the use of skimmed milk flocculation (SMF) to simultaneously concentrate viruses, bacteria and protozoa was evaluated. We selected strains faecal indicator pathogens, such as Escherichia coli Helicobacter pylori. The viruses were adenovirus (HAdV 35), rotavirus (RoV SA-11), bacteriophage MS2 bovine viral diarrhoea virus (BVDV). tested Acanthamoeba, Giardia Cryptosporidium. mean recoveries with q(RT)PCR 66% 24% (MS2), 28% 15% (BVDV), 60% (E. coli), 30% (H. pylori) 21%...
Abstract Wastewater-based epidemiology has shown to be an efficient tool track the circulation of SARS-CoV-2 in communities assisted by wastewater treatment plants (WWTPs). The challenge comes when this approach is employed help Health authorities their decision-making. Here, we describe roadmap for design and deployment SARSAIGUA, Catalan Surveillance Network Sewage. network monitors, weekly or biweekly, 56 WWTPs evenly distributed across territory serving 6 M inhabitants (80% population)....
Water treatment and reuse is gaining acceptance as a strategy to fight against water contamination scarcity, but it usually requires complex treatments ensure safety. Consequently, the electrochemical advanced processes have emerged an effective alternative for remediation. The main objective here perform systematic study that quantifies efficiency of laboratory-scale system inactivate bacteria, bacterial spores, protozoa, bacteriophages viruses in synthetic water, well urban wastewater once...
Hepatitis E virus (HEV) is a common cause of water-borne acute hepatitis in areas with poor sanitation. In 2004 an outbreak HEV infection affected around 2,000 people Eastern Chad (Dar Sila). This paper describes the decrease incidence jaundice syndrome (AJS) from until 2009 when mean 0.48 cases/1,000 people/year was recorded region. Outbreaks AJS were identified some camps 2007 and 2008. Moreover, water samples drinking sources screened for human adenoviruses considered as viral indicators...
Poultry farming may introduce pathogens into the environment and food chains. High concentrations of chicken/turkey parvoviruses were detected in chicken stools slaughterhouse downstream urban wastewaters by applying new PCR-based specific detection quantification techniques. Our results confirm that be useful viral indicators poultry fecal contamination.
Rotavirus A (RVA) is the most common virus associated with infantile gastroenteritis worldwide, being a public health threat, as it excreted in large amounts stool and can persist environment for extended periods. In this study, we performed detection of RVA human adenovirus (HAdV) by TaqMan qPCR assessed circulation genotypes three wastewater treatment plants (WWTPs) between 2015 2016 Catalonia, Spain. was detected 90% HAdV 100% WWTP samples, viral loads ranging 3.96 × 104 3.30 108 RT-PCR...
