The distribution, epidemiology, and socioeconomic impact of Rift Valley fever (RVF) and West Nile (WN) viruses are poorly known in areas of sub-Saharan countries like Ethiopian pastoral region. The human and livestock density in the area has increased greatly in recent years, but little work has been done on arboviral diseases and their potential impact on human and livestock health. The aim of this study was to detect the circulation of zoonotic arboviruses such as Rift Valley fever virus and West Nile viruses in the livestock population and to estimate seroprevalence in Afar pastoral area northeast Ethiopia.

Water Sci Technol

January 2024

Department of Water Engineering, Faculty of Agriculture Technology (Aburaihan), College of Agriculture and Natural Resources, University of Tehran, Tehran, Iran.

The study successfully implemented six low-impact development (LID) methods to manage surface runoff in urban areas: green roof, infiltration trench, bio retention cell, rain barrel, green roof combined with infiltration trench, and rain barrel combined with bio-retention cell. Each method has unique benefits in mitigating surface runoff effects in urban environments. The following four indicators were used to evaluate the methods: runoff volume reduction, peak runoff flow rate reduction, economic sustainability, and social sustainability.

Article Synopsis
  • Bovine leukemia virus (BLV) causes a persistent, often symptomless infection in cattle, and while some countries have eradicated it, global standardization of detection methods is still lacking.
  • A study evaluated the accuracy of 11 different molecular tests for detecting BLV, finding that 29 out of 44 samples were correctly identified and that all methods had diagnostic sensitivities between 74% and 100%.
  • The research emphasized the need for collaboration in standardizing testing methods and suggested the creation of an international calibrator to enhance result consistency and aid in the global eradication of BLV.

Hot pepper is one of the most important spice vegetable crops in Ethiopia and is widely cultivated for dry pod production. However, its productivity is low in Ethiopia due to degraded soil fertility and an unbalanced nutrient supply in the soil. An experiment was conducted to evaluate the effect of NPS fertilizer and cattle manure (CM) on soil chemical properties and hot pepper dry pod yield under irrigation in Jabi Tehnan.

As climate change intensifies, the frequency and severity of waterlogging are expected to increase, necessitating a deeper understanding of the cucumber response to this stress. In this study, three public RNA-seq datasets (PRJNA799460, PRJNA844418, and PRJNA678740) comprising 36 samples were analyzed. Various feature selection algorithms including Uncertainty, Relief, SVM (Support Vector Machine), Correlation, and logistic least absolute shrinkage, and selection operator (LASSO) were performed to identify the most significant genes related to the waterlogging stress response.

The accumulation of polyethylene microplastics (PE-MPs) in soil has raised considerable concerns; however, the effects of their persistence and mitigation on agroecosystems have not been explored. This study aimed to assess the detrimental effects of PE-MPs on a soil-plant system and evaluate their mitigation using a novel microbial consortium (MC). We incorporated low-density polyethylene (LDPE) and high-density polyethylene (HDPE) at two different concentrations, along with a control (0 %, 1 %, and 2 % w/w) into the sandy loam soil for a duration of 135 days.

State Key Laboratory for Animal Disease Control and Prevention, National High Containment Facilities for Animal Diseases Control and Prevention, Harbin Veterinary Research Institute, Chinese Academy of Agricultural Sciences, Harbin 150069, China. Electronic address:

Article Synopsis
  • African swine fever virus (ASFV) poses a significant risk to global economies and food security, with many of its genes not yet fully understood.
  • Research revealed that the CP312R gene is crucial for ASFV replication; its knockout halted viral replication and significantly reduced ASFV infection in lab tests.
  • The study also identified the structure of the CP312R protein and its interaction with RPS27A, a ribosomal protein, which alters RPS27A's location in cells and inhibits the host's protein synthesis, further facilitating the virus's infection process.
