Development of antibodies against severe fever with thrombocytopenia syndrome virus nucleoprotein for diagnosis.

ABSTRACT: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging viral infectious disease caused by a novel Bandavirus in the family Phenuiviridae. The SFTS virus (SFTSV) is transmitted to various hosts, including humans, through tick bites, leading to high fever, thrombocytopenia, and leukopenia, with a high case fatality rate (up to 30%) due to multiple organ dysfunction. Therefore, early diagnosis is crucial for effective treatment and preventing disease transmission. In this study, we aimed to develop and characterize monoclonal antibodies targeting the SFTSV nucleocapsid protein (NP). We generated recombinant NP to screen antibodies against SFTSV. Using phage display technology, we identified candidate single-chain variable fragment (scFv) sequences capable of detecting SFTSV NP. Fiv
