As HIV-2 is intrinsically resistant to nonnucleoside reverse transcriptase inhibitors, it is mandatory to discriminate between HIV types before initiating antiretroviral treatment. Guinea-Bissau has the world's highest prevalence of HIV-2 and HIV-1/HIV-2 dually infected individuals. We evaluated 3 rapid tests for discrimination between HIV-1, HIV-2, and dual infections among 219 patients from Guinea-Bissau by comparing with the gold standard (INNO-LIA). Genie III HIV-1/HIV-2 was the best performer with regard to discriminatory capacity (agreement 91.8%), followed by Immunoflow HIV1-HIV2 (agreement 90.9%) and SD Bioline HIV-1/2 3.0 (agreement 84.5%). Our results underscore the need for evaluation of tests in relevant populations before implementation.

Background: Sepsis, a critical global health challenge, accounted for approximately 20% of worldwide deaths in 2017. Although the Sequential Organ Failure Assessment (SOFA) score standardizes the diagnosis of organ dysfunction, early sepsis detection remains challenging due to its insidious symptoms. Current diagnostic methods, including clinical assessments and laboratory tests, frequently lack the speed and specificity needed for timely intervention, particularly in vulnerable populations such as older adults, intensive care unit (ICU) patients, and those with compromised immune systems.

Bacterial endospores are ubiquitous and are responsible for various human infections. Recently, we reported that an ionic liquid (IL)-based sample preparation method (named pTRUST) facilitated highly efficient shotgun analysis of the Bacillus subtilis spore proteome in trace samples. In this study, we evaluated the efficiency and applicability of the pTRUST technology using three different spore preparations: one purified from the closely related subspecies B.

Cells are the fundamental units of life, comprising a highly concentrated and complex assembly of biomolecules that interact dynamic ally across spatial and temporal scales. Living cells are constantly undergoing dynamic processes, therefore, to understand the interactions between drug molecules and living cells is of paramount importance in the biomedical sciences and pharmaceutical development. Compared with traditional end-point assays and fixed cell analysis, analysis of drug molecules in living cells can provide more insight into the effects of drugs on cells in real-time and allowing for a better understanding of drug mechanisms and effects, which will contribute to the development of drug developing and testing and personalize medicine.

Background: Caprine tuberculosis is a chronic infectious disease caused by Mycobacterium bovis and Mycobacterium caprae. A tuberculosis control programme has been implemented using the comparative intradermal tuberculin (CIT) test. However, infection with Corynebacterium pseudotuberculsis and infection with or vaccination against Mycobacterium avium subspecies paratuberculosis (MAP) may have a negative impact on specificity.
