Article Abstract
We developed a kind of Zaocys dhumnades DNA test kit and it's indexes including specificity, sensitivity and stability were evaluated and compared with the method recorded in Chinese Pharmacopoeia (2010 edition). The bioinformatics technology was used to design primers, sequencing and blast, in conjunction with PCR technology based on the characteristics of Z. dhumnades cytochrome b (Cyt b) gene. The efficiency of nucleic acid extraction by the kit was done in accordance with Pharmacopoeia method. The kit stability results proved effective after repeated freezing and thawing 20 times. The sensitivity results indicated that the lowest amount detected by the kit was 0. 025 g of each specimen. The specificity test of the kit was 100% specific. All repeatability tests indicated the same results when conducted three times. Compared with the method recorded in Chinese Pharmacopoeia, the PCR-based assay kit by our team developed is accurate, effective in identification of Z. dhumnades, it is simple and fast, demonstrating a broad prospect in quality inspection of Z. dhumnades in the future.

Background: Salmonella enterica encompasses over 2,600 serovars, including several commonly associated with severe infection in humans. Salmonella is a major cause of sepsis in Africa; however, diagnosis requires clinical microbiology facilities. Environmental surveillance has the potential to play a role in Salmonella surveillance.

Background: Polymerase chain reaction (PCR)-based Minimal residual disease (MRD) detection is commonly used for core-binding factor acute myeloid leukemia (CBF-AML), but its interpretation in the context of allogeneic hematopoietic stem cell transplantation (allo-HSCT) remains under discussion.
Method: Using Kyoto Stem Cell Transplantation Group registry data, we included 96 patients who underwent allo-HSCT between 2000 and 2019 for CBF-AML.
Results: To assess MRD, quantitative PCR with GAPDH control was most used.

Avian influenza viruses (AIVs) are zoonotic pathogens that pose an increasing global threat due to their potential for significant economic losses in agriculture, spillover into humans, and the risk of a pandemic should human-to-human transmission occur. These concerns underscore the need for rapid, sensitive and specific tools to detect and differentiate circulating AIV subtypes and clades. Current AIV diagnostic methods rely on specialized equipment and trained personnel, limiting their use in the field and in low-resource settings.

Unlabelled: Seeds can serve as a vehicle for the dissemination of pests and pathogens around the world. We recently demonstrated the association of pathogenic isolates with reduced sensitivity to azoxystrobin (quinone-outside inhibitor [QoI]) in naturally infested commercial broccoli seeds. In this study, we further demonstrate that these isolates were also resistant to two succinate dehydrogenase inhibitor (SDHI) fungicides.

In-field molecular diagnostics of plant pathogens are critical for crop disease management and precision agriculture, but tools are still lacking. Herein, we present a bioluminescent molecular diagnostic assay capable of detecting viable pathogens directly in minimally processed plant samples, enabling rapid and precise in-field crop disease diagnosis. The assay, called bioluminescent craspase diagnostics (BioCrastics), leverages newly discovered RNA-activated protease of CRISPR (Craspase) with enzymatic luminescence to generate a cascaded amplification, thus bypasses nucleic acid purification and amplification while achieving sub-nanogram sensitivity for fungal pathogens.
