Article Synopsis
- Bluetongue virus (BTV) causes bluetongue disease in ruminants and is transmitted mainly by biting midges.
- Recent discoveries have identified several atypical BTV serotypes that are generally asymptomatic and don't reproduce well in their insect carriers.
- This report highlights the detection of two atypical BTV strains in Gafsa, Tunisia: the recurring BTV-Y TUN2022 and a new strain called BTV-W TUN2022.
Article Synopsis
- Epizootic hemorrhagic disease (EHD) is a viral disease affecting ruminants, transmitted by midges, and recognized by the World Organization for Animal Health since 2008.
- In 2021, a major outbreak of EHDV serotype 8 occurred in Tunisia, leading to reports of the virus spreading to Italy, Spain, Portugal, and France, marking its first presence outside Australia since 1982.
- The study analyzed the outbreak's epidemiology in Tunisia, identifying eco-climatic factors that influenced infection patterns and suggesting that developed risk maps could aid in controlling and preventing future outbreaks in the region.
Introduction: Since 1999, Tunisia has experienced multiple occurrences of Bluetongue (BT) outbreaks, leading to numerous reported cases of infection and mortality in flocks. The re-emergence of the disease in 2020 caused substantial economic losses in cattle, attributed to the incursion of serotype BTV-4.
Methods: To evaluate the economic impact of the recent BT episode, we conducted a retrospective study on outbreaks that occurred in Tunisia between August and November 2020, focusing on the impact at the owner's level and its effects on both small ruminants and cattle.
Nowadays, 3D PLA-printed parts are widely used in many applications, essentially using the fused filament fabrication technique. While the influence of printing parameters on quasi-static mechanical characterization has been extensively considered within the literature, there are limited accounts of this effect on fatigue performance. The two main aims of this research are first to investigate the effects of the infill density percentage on the fatigue life of dog-bone samples under rotating bending cycling loads, and second to model the fatigue life using Wöhler and Basquin models.

- - EHDV-8, a virus that affects livestock, was first identified in Europe in late 2022, and this study examined its effects on cattle, sheep, and goats after experimental infection.
- - Infected calves mostly showed symptoms such as fever and lesions, with RNA levels peaking at 7 days post infection and remaining stable for the study's duration, while some sheep exhibited fever and consistent RNAemia, but goats showed no RNA presence.
- - All species developed an immune response, with calves showing the strongest, indicating that sheep could also be significant in spreading EHDV-8, which is essential information for developing disease control strategies in livestock.
