The virus has caused extensive outbreaks in cattle and red deer across Italy, Spain, France, and Portugal, exposing vulnerabilities in current outbreak prevention and control measures. This review provides an updated overview of EHDV-8, focusing on its clinical presentation in domestic and wild ruminants, its recent geographic spread in Europe, and the rapid development of targeted vaccines. The European experience highlights the virus's capacity to induce substantial morbidity not only in cattle but also in wild and farmed cervid populations, particularly red deer. However, several aspects of EHDV-8 biology remain poorly understood, including host susceptibility and the mechanisms underlying viral overwintering. Furthermore, the limited availability of genomic data from Africa hampers efforts to trace the evolution and dissemination of EHDV. Strengthening collaboration with North African and Sub-Saharan countries will be crucial to enhance and harmonize surveillance systems across regions. Closing these knowledge gaps is essential for improving preparedness and response strategies, including the development of vaccines tailored to the serotypes currently circulating in endemic areas.","PeriodicalId":23550,"journal":{"name":"Veterinaria italiana","volume":"61 4","pages":""},"PeriodicalIF":0.7,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144993558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As important as it is, little is known about the occurrence and genetic characteristics of the H9N2 detected within the country's poultry farms. This study was therefore carried out to assess the occurrence and the molecular characteristics of H9N2 avian influenza virus strains in broiler and layer farms of the Dakar and Thiès regions. Throughout a period of 16 months, a cross-sectional survey was undertaken, collecting 390 tracheal and cloacal swabs from 39 chicken farms that reported respiratory disease. Viral RNA was isolated and analysed using real-time RT-PCR followed by viral isolation and hemagglutinin gene sequencing on positive samples. Phylogenetic analysis was performed to determine genetic associations with regional strains. Overall, the prevalence was 9.2% across 87 pools made from 390 swabs, with broiler chickens showing a high prevalence of 19.4% and layer hens a low prevalence of 2.0%. The majority of the positive farms were located in the Thiès region, which accounted for 6 out of the 8 positive farms. Phylogenetic analysis revealed that the circulating strain belonged to the G1 lineage and was closely related to Moroccan strains, indicating likely regional spread through poultry trade. The strains did not possess any molecular markers of increased virulence or zoonotic potential. These findings confirm the endemicity of H9N2 in Senegal's important poultry-producing regions and raise the need for targeted surveillance and improved biosecurity to avoid outbreaks and preserve public health.","PeriodicalId":23550,"journal":{"name":"Veterinaria italiana","volume":"61 4","pages":""},"PeriodicalIF":0.7,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145281128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing research has found that most miRNA functions are carried out via intercellular transmission of EVs, which can protect and sort miRNAs. Early detection of disease is crucial for controlling the spread of the disease and improving livestock prognosis. miRNAs play a promising role as circulating biomarkers for early identification of disease. miRNA expressed in paratuberculosis infection has been identified using a variety of samples, including tissue, serum, whole blood, and macrophages. Key findings state that bta-miR-150 and bta-miR-1246 were observed in macrophages, whereas miR-29a and miR-92b were detected in serum and intestinal tissue. such as miR-143 and miR-485 underscore their potential as diagnostic and prognostic biomarkers in different stages of the disease. Studies on personalized medicine involve the detection of biomarker molecules such as miRNA and modulating therapy depending on the patient's severity of the disease, applying techniques like Northern blotting, qPCR, microarrays, and NGS.

This study aimed to update seroprevalence estimates of Rift Valley Fever Virus (RVFV) and identify high-risk areas and animal populations. A cross-sectional survey was conducted between January and May 2024, during which 615 domestic ruminants (cattle, sheep, goats, and camels) were sampled and tested for RVFV-specific antibodies using a competitive enzyme-linked immunosorbent assay (cELISA). The overall RVFV seroprevalence in the Tahoua region was 11.87% (±2.55%). Camels exhibited the highest seroprevalence (36.56%), followed by cattle (17.69%), while small ruminants showed much lower rates: 3.55% in goats and 3.37% in sheep. Significant geographic heterogeneity was observed, with the highest prevalence recorded in Birni N'Konni (30.53%, p < 0.05). No statistically significant differences in seroprevalence were found by sex (p = 0.909) or age (p = 0.876), although adults and females tended to have slightly higher rates. These findings confirm ongoing RVFV circulation in the region and identify camels as the most affected species. The results underscore the need for enhanced, species-specific surveillance, targeted vaccination campaigns, and vector control strategies in high-risk areas to prevent future outbreaks and protect both animal and human health.","PeriodicalId":23550,"journal":{"name":"Veterinaria italiana","volume":"61 3","pages":""},"PeriodicalIF":0.7,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144993539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we characterize and model the bioclimatic suitability of three tick species-Amblyomma aureolatum, A. ovale, and A. sculptum-across Brazil. The climatic niche of each species was quantified using four modelling algorithms (BIOCLIM, GLM, Maxent, and SVM) implemented within an automated modelling workflow (modleR). A total of 585 occurrence records were retained for modelling: 55 for A. aureolatum, 120 for A. ovale, and 410 for A. sculptum, covering the entire Brazilian territory. Amblyomma sculptum exhibited a broader tolerance to temperature and precipitation variability, suggesting a wider potential distribution range compared to the other two species. This species was primarily associated with grassland habitats, such as those in the Cerrado biome. In contrast, A. aureolatum and A. ovale were more strongly associated with forested areas, particularly along the Atlantic Forest coastal region.

Although anecdotal reports suggest seasonal variation in CPE incidence in Nigeria, comprehensive time series analyses remain scarce. This study analyzed clinical records of CPE cases-diagnosed either clinically or via laboratory confirmation-collected from three veterinary clinics in Ibadan, Nigeria, between January 2018 and December 2024. Temporal patterns were decomposed into trend, seasonal, and random components. Stationarity and temporal autocorrelation were assessed using the Augmented Dickey-Fuller and Ljung-Box tests, respectively. An Autoregressive Integrated Moving Average (ARIMA) model was selected using the auto.arima function implemented in R (Vienna, Austria), and subsequently used to forecast CPE incidence over a 24-month horizon. The Box-Pierce test on residuals (P = 0.9409) confirmed the model's adequacy. CPE incidence showed distinct seasonal peaks during the dry months, best captured by the ARIMA (1,1,1)(1,0,0) (model non-seasonal autoregressive order =1, differencing order =1, and moving average order =1; seasonal autoregressive order =1, differencing order = 0, and moving average order = 0; monthly seasonality = 12), and exhibited a negative correlation with historical average monthly rainfall (r = -0.55). However, forecasts for 2025-2026 suggest a gradual decline in incidence and a transition toward year-round occurrence with less pronounced seasonal peaks. These findings underscore the need for continuous preventive efforts.
