Background: In this study, we present a case of Japanese spotted fever (JSF) caused by and use this case to investigate the process of diagnosing and reintegrating traceability of infectious diseases via metagenomic next-generation sequencing (mNGS).
Methods: From data relating to epidemiological history, clinical and laboratory examinations, and mNGS sequencing, a diagnosis of severe JSF was concluded.
Results: A detailed field epidemiological investigation discovered parasitic from a host animal (dog) in the domicile of the patient, within which was detected, along with a diverse array of other potentially pathogenic microorganisms that could cause other infectious diseases.
Conclusion: The mNGS provided an efficient method to diagnose JSF infection. This methodology could also be applied to field epidemiological investigations to establish the traceability of infectious diseases.

Regulation (EU) 2016/429 introduces comprehensive guidelines for managing transmissible animal diseases, including zoonoses. The subsequent Commission Implementing Regulation 2018/1882 categorizes these diseases into five groups, each with specific responses, ranging from mandatory eradication to optional eradication or surveillance. Key regulatory priorities include enhanced animal traceability, biosecurity, wildlife pathogen control, sustainable farming practices, and minimizing the impact of diseases on public health, animal health, and the environment.

Background: Nucleic acid amplification tests (NAATs) assist in the diagnosis of numerous infectious diseases. They are typically sensitive and specific and can be quickly developed and adapted. Far more challenging is the development of standards to ensure NAATs are performing within specification; reference materials take time to develop and suitable reference measurement procedures (RMPs) have not been available.

Equine infectious anemia virus (EIAV) is an equine lentivirus related to human immunodeficiency virus type 1 (HIV-1). Both viruses are related among the Retroviridae family, but their clinical manifestations are different as EIAV causes a long persistent infection with no progressive immune dysfunction in most cases. Today, no treatment is approved against EIAV, contrary to HIV-1, manageable through antiretroviral therapy, known as HAART (highly active antiretroviral therapy) or cART (combination antiretroviral therapy).

The emergence of RND efflux pump gene cluster tmexCD-toprJ threats the clinical use of tigecycline as a last-resort antibiotic. Co-existence of extended spectrum β-lactamases and tmexCD-toprJ can accelerate the emergence of multidrug resistant or extensively drug-resistant Pseudomonas aeruginosa, leading to the production of high-risk clones. This study identified a novel gene cluster, tmexC6D6.

Background: The initial clinical symptoms of severe fever with thrombocytopenia syndrome (SFTS) mainly include high fever, thrombocytopenia and gastrointestinal symptoms, and severe patients may suffer from severe complications such as multiple organ failure, which can lead to death. Studies have shown that central nervous system symptoms are associated with severe adverse outcomes of SFTS, but there are few reports on confirmed cases of SFTS encephalitis. This is a special case in which her initial SFTS symptoms were atypical, while the disease deteriorated rapidly after the appearance of encephalitis.
