An endosymbiotic bacterium of the genus , designated as strain HZ, was cultured from the parasitoid wasp , which develops on the pupae of various host flies. The bacterium was detected in developed on houseflies, , in a poultry facility in Hazon, northern Israel. After culturing, this bacterium displayed no surface motility on Luria-Bertani agar and was rod-shaped and irregular in size, ~10-30 nm in diameter and 5-20 µm in length.

The widespread use of the oral poliovaccine from Sabin strains (tOPV) radically reduced poliomyelitis incidence worldwide. However, OPV became a source of neurovirulent vaccine-derived polioviruses (VDPVs). Currently, circulating type 2 VDPVs (cVDPV2) are the leading cause of poliomyelitis.

Article Synopsis
  • - Dugbe virus (DUGV), a tick-borne virus first identified in Nigeria in 1964, has been found in several African countries and was notably detected in Senegal during the 1970s and 1980s.
  • - Recent research detected three new DUGV isolates from 2877 ticks collected in the Kolda region of Senegal, indicating continued viral presence and potential unnoticed transmission in the area.
  • - Phylogenetic analysis shows these new isolates are related to earlier DUGV strains in West Africa, and the study established a cost-effective method for full-genome sequencing using nanopore technology, revealing a low mutation rate and stable evolution of the virus.

Based on the success of the Sabin2-based vaccine, a next-generation nOPV2 poliovirus vaccine has been developed. For epidemic monitoring and conducting epidemiological investigations, it is necessary to have a diagnostic assay with the ability to differentiate this variant from others. Here we describe such a real-time RT-PCR assay.

The data presented in this paper characterize stable kaolinite edge surfaces. Their equilibrium structure is obtained by DFT methods using the first-principles package CASTEP. The calculations are performed using a basis set of plane waves in the PBE exchange-correlation potential.
