Article Abstract
Background And Aim: Bluetongue is a vector-borne, emerging disease that poses a severe threat to most domesticated animals. A cross-sectional study was conducted to estimate the prevalence of bluetongue virus (BTV) disease in apparently healthy sheep and goats in Kalat, Balochistan.
Materials And Methods: A total of 270 serum samples (sheep: 150 and goat: 120) were collected and screened for the detection of anti-BTV antibodies using a competitive enzyme-linked immunosorbent assay. The data regarding different contributory risk factors were also collected using a predesigned questionnaire.
Results: It revealed that overall, 27.4% (74/270, 95% confidence interval, χ = 1.71, p = 0.12) prevalence in both sheep and goat populations. The highest prevalence of 47% (32/68) was recorded in Surab city with the lowest prevalence of 15.49% (11/71) in the Manguchar area. In contrast, in Kalat 28.1% (9/32), Daan area 24% (12/50), and Marap area 22.44% (11/49), seropositivity was recorded. Upon sex bases, antibodies were almost equally found in both male 28.57% (8/28) and female 27.27% (66/242) animal populations. Moreover, all four breeds (Balochi, Khurasani, Lehri, and Rakhshani) were equally and potentially seropositive. The Khurasani breed was the most susceptible to 34.69% (17/49), followed by the Balochi breed, 45/145 (31%) seropositivity. The prevalence of BTV was 16.66% (1/6) in Rakhshani breed and 15.71% (11/70) in Lehri breed., Ticks were found in almost 21% of animals, while 93% of animals were reared on open grazing in rangelands.
Conclusion: This study clearly indicates widespread BTV infection in small ruminants in the study area that may pose serious threats to livestock farming. Further extensive studies are recommended to study the prevalence of disease in different agroecological zones of the province. This also warns the high-ups to manage concrete efforts to eradicate and control the disease in the area.

Wildlife species are routinely captured for translocation, general health monitoring, and research-based pursuits to guide wildlife management. Mule deer () were captured for various research projects and management actions in the Trans-Pecos and Panhandle regions of Texas from 2015 to 2019. The objective of this study was to develop hematologic and biochemical parameters for free-ranging mule deer in Texas and to develop a health monitoring system for current and future mule deer population management.

The bluetongue virus (BTV), transmitted by biting midges, poses a significant threat to livestock globally. This orbivirus induces bluetongue disease, leading to substantial economic losses in the agricultural sector. The current control measures have limitations, necessitating the development of novel, efficient vaccines.

Article Synopsis
- - Culicoides spp., small biting midges, are important vectors of viruses like African horse sickness and bluetongue that affect livestock; a study in Yunnan Province, China examined their diversity and abundance on two cattle farms from March 2022 to March 2023.
- - Light traps collected 19 species of Culicoides, with C. oxystoma being the most prevalent, making up over 63% of the total 8,343 specimens; 10 species were screened for several viruses using RT-qPCR.
- - Notably, one strain of Yunnan Orbivirus was isolated from cattle blood, and the first connection between a totivirus (YSToV) and Culicoides was found

Article Synopsis
- * Blood samples from 354 goats were analyzed, revealing overall seroprevalence rates of 6.21% for N caninum and 7.06% for BTV, with group II farmers (small herd size) showing the highest rates.
- * The findings highlight the need for better management practices among smaller goat producers to reduce disease prevalence and emphasize the importance of effective health strategies in the region.
