Summary: Microsporidia are obligate, intracellular, spore-forming parasites that infect a wide range of hosts involving almost all animals. Enterocytozoon hepatopenaei (EHP), a microsporidium, mainly infects the hepatopancreas of shrimp, hindering host growth. This study identified and characterized the polar tube protein 2 of EHP for potential epidemiological studies and diagnosis.

Summary: Fire blight is a plant infection that contaminates edible plants globally and causes socio-economic problems in agricultural and livestock industries. A new fluorogenic probe, B-1, was developed for real-time on-site detection of fire blight bacteria. It exhibited bright emission properties in the presence of the bacteria, allowing for fluorescence imaging and real-time detection from infected host plant tissues. The detection limit for E. amylovora was excellent at 102 CFU/mL. The introduction of a portable UV device further enhances the potential of this diagnostic technology for detecting fire blight in agricultural and livestock industries.

Summary: Endosome trafficking plays a crucial role in pollen tube polar growth, with NtGNL1 regulating this process. Comparative proteomic analysis identified proteins involved in NtGNL1-dependent endosome trafficking, indicating a potential link to the Pentose phosphate pathway and highlighting the Sec7 domain as a core functional region of NtGNL1.

Summary: A thermostatic sensor for the rapid detection of Vibrio parahaemolyticus was developed using a 3D nano nucleic acid hybrid material. The sensor, called single cross-priming fluorescence (SCPF) sensor, utilized mesoporous silica nanoparticle/nucleic acid-doped nanoflowers and was accompanied by a portable polymerase chain reaction (PCR) tube fluorescence reader. The aggregation of silica nanoparticles increased the local concentrations, enhancing the efficiency of single cross-priming amplification (sCPA). The detection limit of the sensor was 2.4 copies/mL.

Summary: To ensure food safety, rapid screening and quantitative detection of foodborne pathogens are essential. This study developed a dual-signal response biosensing strategy that combines visual fluorescent signal and quantitative electrochemical signal for simultaneous detection. A signal probe consisting of deoxyribozyme (DNAzyme)-ferrocene immobilized on MXene/gold nanobipyramid/antimicrobial peptide was used. The DNAzyme enabled a click reaction to produce visual fluorescent signal, while ferrocene provided an electrochemical detection signal to confirm foodborne pathogen contamination. This dual-signal biosensing strategy exhibited a wide detectable range and low detection limit, making it a useful tool for on-site detection of foodborne pathogens.

Summary: Chinese Sacbrood Virus (CSBV) causes Chinese sacbrood disease (CSD) in Apis cerana cerana larvae, resulting in significant economic losses. Through lipidome analysis using high-resolution mass spectrometry, this study identified altered lipid composition in CSBV-infected larvae, with sphingolipids potentially playing a role in CSD progression. Specific lipid changes, such as the significant increase in TG (39:6), could serve as biomarkers for early CSD detection. This research sheds light on the relationship between lipid metabolism and CSBV replication in honeybee larvae.

Summary: This study used label-free quantitative proteomics to analyze the hepatopancreas of shrimp infected with Enterocytozoon hepatopenaei (EHP). The results showed that EHP infection leads to down-regulation of lipid metabolism and energy production, as well as hormone metabolism disorder, ultimately causing stunted growth in shrimp.

Summary: Insect-associated microorganisms are important for insect health and development. This study analyzed the bacterial community in the larval gut, nest soil, and brood provision of Osmia excavata. Sequencing of the microorganisms revealed differences in diversity and composition among the three environments, but similarities were observed in the gut microbiota across different locations. The results suggest that habitat similarity influences the bacterial community diversity in the gut of O. excavata.
