This study was conducted to develop and evaluate protein-G-based lateral flow assay (LFA) for rapid serodiagnosis of brucellosis in various domesticated animal species. The assay diagnostic performance was tested with 144 reference and 356 field sera samples and then compared with other serological assays. Results revealed that LFA showed 89% and 99% sensitivity and specificity, respectively, when compared with competitive ELISA as the gold standard. This study demonstrated LFA alone as a potential serodiagnostic assay for rapid serodiagnosis of brucellosis in various domesticated animal species.

Rose Bengal antigen and smooth lipopolysaccharide (s-LPS) were produced from a field strain of ("homologous" antigens) and from the reference strain S99 ("heterologous" antigens); they are currently used for the diagnosis of brucellosis in cattle, water buffaloes, sheep, goats, and pigs, as recommended in the Manual of Diagnostic Tests and Vaccines for Terrestrial Animals of the World Organization for Animal Health (WOAH). "Homologous" and "heterologous" antigens were used in a rapid serum agglutination test (Rose Bengal test, RBT) and a competitive ELISA assay (c-ELISA) to test a panel of sera, blood, and other body fluids (cerebrospinal fluid, pericardial fluid, tracheal fluid, and aqueous humor) collected from 71 individuals belonging to five cetacean species (; ; ; ; and ), which were found stranded on the Italian coastline. Six animals were positive for spp.

Raynaud's phenomenon (RP) is characterized by episodic vasospasm of the small blood vessels, primarily affecting the fingers and toes. Management includes lifestyle modifications, pharmacological treatments, and in severe cases, surgical interventions. Here we report a case of an 80-year-old male patient with a history of hypertension, dyslipidemia, obesity, and atrial fibrillation who presented to the emergency department with edema, cyanosis, and intense pain in the fingers of both hands following a mild COVID-19 infection (no dyspnea or hypoxemia).

Rapid antigen diagnostic tests (Ag-RDTs) that quickly and accurately identify SARS-CoV-2 are an essential part of the COVID-19 response, but multiple factors can affect the validity of Ag-RDTs results. In Cambodia, several commercial Ag-RDTs have become available since the COVID-19 outbreak, but quality control (QC) and external quality assurance (EQA) of these rapid tests have yet to be fully and systematically implemented. We collaborated with laboratory experts in Australia and piloted an EQA programme of the commonly used COVID-19 Ag-RDTs at the University of Health Sciences' MERIEUX Laboratory (Tier 1 site-responsible for the in-country receipt and distribution of QA material) and four other participating laboratories (Tier 2-healthcare facility based) between November 2021 and November 2022.

Background: The challenge of dealing with isolated reactive treponemal chemiluminescence immunoassay (CIA) results in clinical practice has prompted the development of a more efficient algorithm for distinguishing true infection from false reactivity in isolated CIA sera.
Methods: A prospective cohort study was conducted at Wuhan Tongji Hospital, involving 119,002 individuals screened for syphilis using CIA from January 1, 2015, to January 6, 2017. Samples with reactive CIA results underwent simultaneous testing with the T.
