Background: Point-of-care testing (POCT) is a valuable diagnostic approach for identifying pathogens such as Group A Streptococcus (GAS) and influenza. Early detection through POCT allows for timely initiation of appropriate treatments improving public health outcomes and minimizing antibiotic misuse. Community pharmacists are well positioned to offer POCT and treatment, but they face significant system level barriers to widespread implementation and reach.

Streptococcus pneumoniae (SPN) is a significant pathogen causing pneumonia and meningitis, particularly in vulnerable populations like children and the elderly. Available pneumonia vaccines have limitations since they only cover particular serotypes and have high production costs. The emergence of antibiotic-resistant SPN strains further underscores the need for a new, cost-effective, broad-spectrum vaccine.

Shotgun metagenomics offers a broad detection of pathogens for rapid blood stream infection of pathogens but struggles with often low numbers of pathogens combined with high levels of human background DNA in clinical samples. This study aimed to develop a shotgun metagenomics protocol using blood spiked with various bacteria and to assess bacterial DNA extraction efficiency with human DNA depletion. The Blood Pathogen Kit (Molzym) was used to extract DNA from EDTA-whole blood (WB) and plasma samples, using contrived blood specimens spiked with bacteria for shotgun metagenomics diagnostics via Oxford Nanopore sequencing and PCR-based library preparation.

Immunochromatographic assays (ICAs) provide simple and rapid strategies for bacterial diagnosis but still suffer from the problems of low sensitivity and high dependency on paired antibodies. Herein, the broad-spectrum capture and detection capability of the antibody-free electropositive nanoprobe are clarified for bacteria for the first time and an ultrasensitive fluorescent ICA platform is constructed for the simultaneous diagnosis of multiple pathogens. A magnetic multilayer quantum dot nanocomposite with an amino-embedded SiO shell (MagMQD@Si) is designed to enrich bacteria from solutions effectively, offer high luminescence, and reduce background signals on test strips, thus greatly improving the sensitivity and stability of ICA technique for pathogen.

Pneumonia is a prevalent acute respiratory infection and a major cause of mortality and hospitalization, and the urgent demand for a rapid, direct, and highly accurate diagnostic method capable of detecting both () and () arises from their prominent roles as the primary pathogens responsible for pneumonia. Herein, two luminescent iridium complexes with nonoverlapping photoluminescence spectra, iridium(III)-bis [4,6-(difluorophenyl)-pyridinato-N,C'] picolinate (abbreviated as Ir-B) and bis (2-(3,5- dimethylphenyl) quinoline-C2,N') (acetylacetonato) iridium(III)) (abbreviated as Ir-R), were unprecedently proposed to construct a novel wavelength-resolved magnetic multiplex biosensor for simultaneous detection of and based on catalytic hairpin assembly (CHA) signal amplification strategy combined with dye-doped silica nanoparticles. Notably, the proposed wavelength-resolved multiplex biosensor not only exhibits a broad linear range from 50 pM to 10 nM but also demonstrates excellent recovery rates for (96.
