The diagnosis developed with the developing techniques using more specific techniques. The aim is to study the epidemiology and molecular detection of HBV and HCV in the Anbar governorate (Fallujah and Amiriyah) and the correlation between the viral load of HBV and HCV on liver functions. Materials and Methods: A cohort of 5463 tested for HBV viral infection and 5873 tested for HBV viral infection patients' information were collected from units in Fallujah and Amiriyah Hospitals as well as private laboratories who sent for HBV or HCV detection from 15th January 2021 to 20th November 2021 using a questionnaire and diagnosed with rapid tests, the positive results subjected for testing with ELISA and samples tested using q-PCR techniques. Findings: Among the studied cohort, the prevalence of HBV infections was high compared to HCV, with the highest impact in females and the ages of young adults (29-30 years). Furthermore, viral loads were high in HCV-infected patients compared to HBV. Finally, liver enzymes (ALP, AST, and ALT) were significantly high in HCV-infected patients compared to HBV. Conclusion: The study concluded that females have a higher rate of infection with higher progression of the HBV and more morbid liver enzymes. The highest affected age groups are the highest communicational and economic activity group of young adults with elevated impact on the liver with HCV viral load increasing.","PeriodicalId":7473,"journal":{"name":"Advances in Virology","volume":"2025 ","pages":"9970549"},"PeriodicalIF":1.1,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12226165/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144558800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The gold standard to assess this is analysis of neutralization capacity, but such assays are not widely available, with antibody levels often used as an approximation of the neutralizing ability. Avidity index is a measure of antibody function and avidity maturation contributes to long-lasting immunity. Objectives: To evaluate if the avidity index gives a better estimation of the neutralizing ability compared with anti-spike IgG levels and to compare the immune response between infection and vaccination against SARS-CoV-2. Study Design: Serum samples from prospectively included patients with either PCR-confirmed COVID-19 or COVID-19-naïve after vaccination were analyzed for anti-spike IgG, avidity index, and neutralizing titer at 1, 3, and 6 months after infection or vaccination. Results: A significant correlation between anti-spike IgG level and neutralization titer was found (Spearmanr s = 0.88, p < 0.001), but for the avidity index, the correlation was lower (Spearman r s = 0.62, p < 0.001). Anti-spike IgG level, avidity index, and neutralization titer were significantly higher in the vaccine cohort. Natural infection failed to yield high-avidity antibodies. Over time, the antibody levels and neutralization titer declined in both the vaccine and infection cohorts. Conclusion: Anti-spike IgG levels can be used as an estimation of the neutralizing titer, with the avidity index not contributing to a better estimation. There is a stronger initial immune response after vaccination, compared with natural infection. However, specific antibody levels decline over time, highlighting the importance of vaccine boosters.","PeriodicalId":7473,"journal":{"name":"Advances in Virology","volume":"2025 ","pages":"2265813"},"PeriodicalIF":1.1,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12185213/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144473751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The diversity of symptoms observed in agave and the negative results of the different diagnostic tests indicated the possible presence of different unknown viruses, and so we conducted high-throughput sequencing (HTS) analyses of viral RNA. The bioinformatics analyses showed the complete genomes of isolates of Vitivirus genus, Potexvirus genus, Tepovirus genus, and the partial genome of a Badnavirus genus in mixed infections in agave samples from commercial plots and in ornamental plants. The presence of each virus was confirmed by sequencing and cloning of the RT-PCR products of the capsid protein (CP), using specific oligonucleotides designed from the sequences obtained by HTS.

Bacterial and fungal infections are a major cause of peritonitis in PD patients. Viral infections have rarely been reported in association with peritonitis in PD patients; about 20% of cases are fungal and bacterial culture-negative (so-called sterile peritonitis). Several possible viral causes are reported to cause peritonitis, Coronaviruses are an important virus group that has been found to cause peritonitis in animals (cats), although in human beings these viruses have not been reported to associate with peritonitis. The purpose of this study was to investigate whether the intestinal form of Human 229E coronavirus plays a role in peritonitis and EPS for several peritoneal fluid samples collected from patients with confirmed EPS. Thirty-seven peritoneal fluid samples from 12 patients with histologically confirmed EPS from Manchester University Hospitals were extracted using QIAamp RNA Mini Kit to purify viral RNA. The purified RNA was reverse transcribed and tested using a pan-coronavirus PCR designed to pick up all known human and animal coronaviruses.

In this study, we carried out molecular evaluation on the targeted fusion (F) gene region in the RSV-positive samples of Iraqi patients during the autumn and winter of 2022/2023. One hundred and fifty patients with lower respiratory tract infections were screened for RSV using reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Sanger sequencing was performed on the RSV-positive samples targeting 1061 nucleotides (from nucleotide 6168 to 7228 within the RSV genome) and 1000 nucleotides (from nucleotide 6122 to 7121 within the RSV genome) of the F gene region for RSV-A and RSV-B, respectively. The results showed some nucleotide changes within the targeted F gene, which were grouped in distinct clade, closely related to isolates from Austria, Argentine, Finland, and France through phylogenetic analysis. In silico protein modeling using the SWISS-MODEL and I-TASSER web tools based on nonsynonymous changes of amino acid sequence showed some good-predicted models that can be utilized for antiviral screening. In summary, the identified nucleotide variations in the F gene could influence vaccine development as the F protein is the primary target for the major antigen of RSV. Molecular surveillance data of RSV local isolates are also essential for studying new genomic changes and enable the prediction of potential new antiviral agents.","PeriodicalId":7473,"journal":{"name":"Advances in Virology","volume":"2025 ","pages":"8864776"},"PeriodicalIF":1.1,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11971507/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143794469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given that no HCV vaccine is currently available, comprehensive epidemiological understanding is crucial for devising effective prevention strategies. In North Africa, existing data on HCV infection and HCV-associated HCC are frequently outdated or limited to specific populations. This systematic review aims to offer new insights into the epidemiology of HCV infection, HCV genotype distribution, and HCV-related HCC in this region. We collected data from electronic databases: PubMed, ScienceDirect, ResearchGate, Google Scholar, and public health reports between 1989 and 2023. We reported the studies carried out in each country in general populations and in groups exposed to HCV infection. Our results show that HCV prevalence varies from 0.5% to 4.61% among the general populations in North African countries. HCV genotype 1 remains the most dominant in the Greater Maghreb region, while genotype 4 is the most dominant in the Nile Valley region. HCC incidence varies between the five countries, and HCV is responsible for 60% of cases, with male dominance. Egypt had the highest number of deaths from HCV-associated HCC. Other factors such as HBV, diabetes, and alcohol use are also responsible for HCC in North Africa. Urban growth and socioeconomic changes have impacted HCV prevalence in the North African region, especially among rural populations, and introduced new risks, such as coinfections and Type 2 diabetes. Here, we propose some recommendations for HCV control and management by patient category in North Africa.","PeriodicalId":7473,"journal":{"name":"Advances in Virology","volume":"2025 ","pages":"9927410"},"PeriodicalIF":1.1,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11957868/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143750581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
