Background: Serological diagnosis of () is fre-quently challenging because of cross-reactivity with other parasitic nematodes. Therefore, it is necessary to introduce novel serological tests with high performance to properly diagnose this neglected parasitic infection. The purpose of the current study was to design a multi-epitope construct for the diagnosis of .
Methods: For the purpose of this study, first, highly antigenic segments and potential immunodominant epitopes of were identified from two antigenic proteins, and then all of the selected parts were linked by an appropriate linker. Next, the physicochemical features of the designed construct were analyzed. Then, tertiary structures of the construct were built and evaluated to find out the best one. Lastly, the amino acid sequence was reverse-translated and optimized for over-expression in (.
Results: The bioinformatic evaluation indicated that the designed protein construct could be hydrophilic, thermostable, and acidic and the estimated half-life was more than 10 in .
Conclusion: According to the results of the study, the designed construct could be used as an efficient antigen in the ELISA system for serological diagnosis of human strong-yloidiasis.

Background Objectives: Co-infection of dengue virus and acute hepatitis A virus in paediatric population is a major health concern in endemic countries. This cross sectional retrospective study was conducted to evaluate the prevalence of hepatitis A virus among the clinically dengue suspected paediatric cases presented at our tertiary care centre during the two-year period (2022-2023).
Methods: A total of 747 dengue suspected paediatric clinical specimens were included in this study.

Currently commercial colorimetric paper lateral flow immunoassays exhibit insufficient limit of detection (LOD) and limited clinical sensitivity toward the detection of SARS-CoV-2 antigens, which causes a high false negative rate. To mitigate this issue, a new plasmon-enhanced fluorescence probe was developed for paper lateral flow strips (PLFSs). The probe is made of a sandwich-structured Ag-core@silica@dye@silica-shell nanoparticle in which fluorescent dyes are sandwiched between the plasmonic Ag core and the silica outer shell, and the separation distance between the Ag core and the dye molecules is controlled by the silica space layer.

Tick-borne infections are the most common vector-borne diseases in the USA. Ticks harbor and transmit several infections with Lyme disease being the most common tickborne infection in the US and Europe. Lack of awareness about tick populations, specific diagnostic tests, and overlapping signs and symptoms of tick-borne infections can often lead to misdiagnosis affecting treatment and the prevalence data reported especially for non-Lyme tick-borne infections.

Background: In May, 2022, the first global outbreak of mpox (formerly known as monkeypox) occurred. In response, public health agencies in the UK have made smallpox vaccines available to individuals at the highest risk of infection. With mpox cases still being detected globally, novel tools are required to aid with diagnosis, serosurveillance, and the evaluation of immune responses following infection and immunisation with current and new vaccine candidates.
