Alphaviruses from Africa, such as Middelburg virus (MIDV), and Sindbis virus (SINV), were detected in horses with neurologic disease in South Africa, but their host ranges remain unknown. We investigated the contribution of alphaviruses to neurologic infections and death in wildlife and domestic animals in this country. During 2010-2018, a total of 608 clinical samples from wildlife and nonequine domestic animals that had febrile, neurologic signs or unexplained deaths were tested for alphaviruses. We identified 32 (5.5%) of 608 alphavirus infections (9 SINV and 23 MIDV), mostly in neurotissue of wildlife, domestic animals, and birds. Phylogenetic analysis of the RNA-dependent RNA polymerase gene confirmed either SINV or MIDV. This study implicates MIDV and SINV as potential causes of neurologic disease in wildlife and nonequine domestic species in Africa and suggests a wide host range and pathogenic potential.

African Swine Fever (ASF), caused by the highly contagious African swine fever virus (ASFV), poses a significant threat to domestic and wild pigs worldwide. Despite its limited host range and lack of zoonotic potential, ASF has severe socio-economic and environmental consequences. Current control strategies primarily rely on early detection and culling of infected animals, but these measures are insufficient given the rapid spread of the disease.

This study aims to identify the role of various natural, socioeconomic, and demographic factors in the development of the African swine fever (ASF) epizootic among wild boar in the Russian Federation (RF) from 2007 to 2023. In this study, particular emphasis was placed on testing the significance of wild boar population density as a key factor contributing to the spread of ASF within this population. During the study period, 1711 outbreaks in wild boars were reported in the RF, accounting for 41.

Zoonotic infections-bacterial, viral, fungal, or parasitic-can spread from domestic or wild animals to humans, either directly or via intermediate vectors. In vascular and endovascular surgery, infections are rare and usually caused by common bacteria with familiar presentations. In contrast, zoonotically transmitted, atypically behaving organisms pose diagnostic and therapeutic challenges due to their elusive nature and resistance to conventional detection methods.

Many species from the genus are causative agents of the bacterial zoonosis brucellosis. Until recently, it was generally believed that these bacteria exhibit strict host specificity; however, recent findings suggest otherwise. is an atypical species, no threat to humans, with a broad host spectrum, primarily found in wildlife and rodents, and is the only species isolated from soil, aquatic environments, and frogs, suggesting its environmental persistence and adaptability to diverse ecological niches.

The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is capable of infecting multiple species through human-to-animal spillover. Human to animal spillovers have been documented both in domestic and wild animal species. Due to close contact in shared households, pet dogs may be at increased risk for contracting the SARS-CoV-2 virus from infected individuals in the same household.
