It was discovered in 1995 among animal handlers in Saudi Arabia. AHFV spreads through close contact with infected animals and tick bites. Symptoms range from fever and flu-like symptoms to hemorrhagic manifestations, and rarely, encephalitis. The Saudi Arabian Ministry of Health has reported 604 cases so far. There are no approved vaccines, antiviral therapies, or routine screening systems for AHFV. This lack of preventive measures makes it challenging to predict future outbreaks or re-emergence in endemic regions of Saudi Arabia.Methodology: We cloned, sequenced, analyzed, expressed, and purified the recombinant AHFV capsid protein (CP) using the PET-28a (+) vector. The CP gene was amplified through reverse transcriptase polymerase chain reaction (RT-PCR) and cloned into a vector. The expression and purification processes were carried out in E. coli.Results: The sequence of the CP gene was deposited in GenBank (Accession number OR785375) and designated as AHFV-SIAU-1-KSA. Sequence analysis revealed similarities with other AHFV isolates obtained from humans, animals, and ticks. Phylogenetic analysis showed that the AHFV CP gene formed distinct clusters with other AHFV genomes collected at different time intervals. The expressed protein was successfully purified and analyzed by SDS-PAGE.Conclusions: This study is the first to document the cloning, expression, and purification of the recombinant AHFV CP gene from Saudi Arabia. The purified protein will be used to develop a serological assay for routine screening of AHFV samples in humans, animals, and ticks in Saudi Arabia.","PeriodicalId":49160,"journal":{"name":"Journal of Infection in Developing Countries","volume":"18 12","pages":"1806-1814"},"PeriodicalIF":1.4,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143014750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PPR has significant economic and social impacts, especially in Africa, Asia, and the Middle East, where small ruminants are vital to rural livelihoods and food security. This disease is a priority for global eradication due to its disproportionate impact on low-income farmers and wildlife conservation.Methodology: A literature review was conducted to capture recent information on the epidemiology, diagnosis, host range, transmission, pathogenesis, economic impact, vaccination strategies, and eradication efforts for PPR. This review also explores future perspectives to address gaps in the current understanding and control of the disease.Results: The review highlights that PPR remains a severe challenge in low-resource areas, causing notable economic loss and endangering wildlife. Vaccination efforts have shown effectiveness, though limited accessibility and high costs persist as barriers. The disease has gained attention from international organizations aiming for global eradication by 2030, with ongoing advancements in diagnostics and surveillance methods showing promise in control efforts.Conclusions: This review underscores recent advancements in PPR research, focusing on disease distribution, diagnostic improvements, and control strategies. These findings are valuable for regional and global eradication initiatives, providing a foundation for policies that support sustainable livestock economies and biodiversity conservation. International collaboration, effective vaccination programs, and strategic surveillance are essential to achieve the 2030 eradication goal and secure the health of vulnerable livestock populations.","PeriodicalId":49160,"journal":{"name":"Journal of Infection in Developing Countries","volume":"18 12","pages":"1837-1845"},"PeriodicalIF":1.4,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143014752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their involvement in chronic bacterial infections, particularly those caused by pathogens endemic to developing countries, such as Mycobacterium tuberculosis (Mtb), remains incompletely understood. Cytokine microenvironment determines the expression of co-inhibitory molecules in tuberculosis: Results indicate that the cytokine IL-12, in the presence of Mtb antigens, can enhance the expression of co-inhibitory molecules while preserving the effector and memory phenotypes of CD4+ T cells. Intersection of immune checkpoint inhibitors` role in cancer therapy and active tuberculosis: As discussed, co-inhibitory molecules` expression is crucial for effectively controlling inflammation during chronic bacterial infections. It has been suggested that monoclonal antibodies (mAbs) developed for cancer immunotherapy, known as immune checkpoint inhibitors (ICIs), may be associated with the reactivation of latent tuberculosis (LTB), though this occurrence has been rarely reported. Immune checkpoint molecules function as a \"brake\" to protect the host from the pathological effects of the immune response during chronic bacterial infections, which contrasts with the concept of exhaustion in the context of cancer. This means cells expressing co-inhibitory molecules on their surface can be paradoxically activated, as suggested in this review.","PeriodicalId":49160,"journal":{"name":"Journal of Infection in Developing Countries","volume":"18 12","pages":"1824-1836"},"PeriodicalIF":1.4,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143014755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
