Article Abstract

Salmonella genomic island 2 (SGI2) is an independently derived genomic island related to SGI1 with the integron in a different position. The integron in SGI2 was found to include an additional 2.1 kb derived from the tni module of Tn5058, Tn502, or Tn512 that was not detected previously. Independent evolution of the backbone was confirmed with 21 single base differences found in over 11.5 kb, representing 40% of the 27.4-kb SGI2 backbone.

The global spread of antimicrobial resistance (AMR) poses a serious threat to public health, with hospital wastewater treatment plants (WWTPs) recognized as a key hotspot for resistant pathogens and antibiotic resistance genes (ARGs). This study employed advanced hybrid sequencing platforms to provide a comprehensive resistomic analysis of a Qingdao WWTP in China, revealing previously uncovered AMR transmission risks. We identified 175 ARG subtypes conferring resistance to 38 antimicrobials, including the last-resort antibiotics, highlighting the extensive and concerning resistance reservoir within this environment.

The type III secretion system in Pseudomonas syringae complex pathogens delivers type III effectors (T3Es) into plant cells to manipulate host processes, enhance survival, and promote disease. While substantial research has focused on herbaceous pathogens, T3Es in strains infecting woody hosts are less understood. This study investigates the HopBL family of effectors in Pseudomonas savastanoi, a pathogen of woody plants.

Obesity has been associated with non-Hodgkin lymphoma (NHL), but the evidence is inconclusive. We examined the association between genetically determined adiposity and four common NHL subtypes: diffuse large B-cell lymphoma (DLBCL), follicular lymphoma, chronic lymphocytic leukemia, and marginal zone lymphoma, using eight genome-wide association studies of European ancestry (N = 10,629 cases, 9505 controls) and constructing polygenic scores for body mass index (BMI), waist-to-hip ratio (WHR), and waist-to-hip ratio adjusted for BMI (WHRadjBMI). Higher genetically determined BMI was associated with an increased risk of DLBCL [odds ratio (OR) per standard deviation (SD) = 1.

Mud crab () is an economically important aquaculture crustacean species in China and Southeast Asia countries. However, the catches of wild mud crabs declined sharply due to overfishing and environmental pollution. Therefore, it is necessary to understand the current genetic resources and population history of mud crab (), which would provide appropriate guidelines for genetic resource management and breeding programs.
