Article Synopsis
- * The study involved a 1:2 case-control approach, which discovered that 22.5% of the 80 exposed people had acute infections, notably higher than the 2.9% infection rate in unexposed individuals, with cucumber in sauce identified as a significant risk factor.
- * Investigation also revealed poor kitchen hygiene practices, such as mixing utensils for raw and cooked foods, leading to cross-contamination from defrosted pork; overall findings highlight the need for better food hygiene education in rural areas
In August 2023, we identified a case of dengue fever in Yantai City, which was imported from Xishuangbanna, China. To investigate its evolutionary history and population dynamics, we utilized the metatranscriptomic method to obtain the virus' whole genome sequence. Together with 367 selected dengue virus whole genome sequences from the NCBI database, we constructed a time-scaled Maximum Clade Credibility (MCC) tree.

- Esteya vermicola shows potential as a biological control agent against pine wilt disease caused by the pinewood nematode (PWN), but interactions at the population and molecular levels are not fully understood.
- The study reveals that E. vermicola can grow in pine xylem and respond rapidly to PWN invasion, despite its slow overall growth rate, highlighting a dispersal pattern linked to nematode migration.
- Transcriptomic analysis indicates that E. vermicola has mechanisms to tolerate pine defense compounds, specifically β-pinene, enhancing our understanding of its role in managing pine wilt disease effectively.
Analysis of the Transmission of SARS-CoV-2 Delta VOC in Yantai, China, August 2021.
Front Med (Lausanne)
May 2022
Objective: Starting 31 July 2021, a SARS-CoV-2 outbreak occurred in Yantai, Shandong Province. The investigation showed that this outbreak was closely related to the epidemic at Nanjing Lukou Airport. In view of the fact that there were many people involved in this outbreak and these people had a complex activity area, the transmission route cannot be analyzed by simple epidemiological investigation.

For paired populations of 31 accessions, respectively, grown under 100 or 380 ppm CO, we compared phenotypic traits related to vegetative growth and flowering time. Four accessions showed the least variation in measured growth traits between 100 ppm CO and 380 ppm CO conditions, though all accessions exhibited a dwarf stature with reduced biomass under low CO.
