We evaluated the rapid immunochromatographic test for severe acute respiratory coronavirus 2 (SARS-CoV-2) antigen detection using 16 saliva specimens collected from 6 COVID-19 hospitalized patients, and detected N-antigen in 4 of 7 RT-PCR positive specimens. This POCT detected SARS-CoV-2 antigen in saliva and would be useful for COVID-19 diagnosis.

The pathogenic oomycete Pythium insidiosum causes a fatal infectious illness known as pythiosis, impacting humans and certain animals in numerous countries in the tropics and subtropics. Delayed diagnosis is a primary factor contributing to the heightened morbidity and mortality associated with the disease. Several new serodiagnostic methods have been developed to improve the identification of pythiosis.

Clostridioides difficile is a Gram-positive, spore-forming anaerobic enteropathogen responsible for a wide spectrum of clinical diseases ranging from mild diarrhoea to pseudomembranous colitis. It is the first cause of healthcare-associated diarrhoeas, but community-associated Clostridioides difficile infections (CDI) are increasingly reported in patients without the common risk factors (age > 65 years, previous antibiotic treatment). The main C.

Diagnostics often require specialized equipment and trained personnel in laboratory settings, creating a growing need for point-of-care tests (POCTs). Among the genetic testing methods available, Loop-mediated Isothermal Amplification (LAMP) offers a viable solution for developing genetic POCT due to its compatibility with simplified devices. This study aimed to create a genetic test that integrates all steps from sample processing to analyzing results while minimizing the complexity, handling, equipment, and time required.

Gatifloxacin (GAT), an antibiotic belonging to the fluoroquinolone (FQ) class, is a toxicant that may contaminate food products. In this study, a method of ultrasensitive immunochromatographic detection of GAT was developed for the first time. An indirect format of the lateral flow immunoassay (LFIA) was performed.
