“…In South Africa and Chile, Alphaarterivirus equid strains that infect donkeys have been reported [57]. Comparative genomic sequence and phylogenitc analyses of these strains with other equid Alphaarterivirus equid strains showed the existence of a new Alphaarterivirus genotypes in these regions [67,68]. In a study conducted by Bolfa et al [69], only one donkey was positive for the presence of antibodies against Alphaarterivirus equid, and a possible explanation is that this animal could have been an asymptomatic carrier that could have been imported.…”

Donkeys (Equus asinus) and mules represent approximately 50% of the entire domestic equine herd in the world and play an essential role in the lives of thousands of people, primarily in developing countries. Despite their importance, donkeys are currently a neglected and threatened species due to abandonment, indiscriminate slaughter, and a lack of proper sanitary management. Specific knowledge about infectious viral diseases that affect this group of Equidae is still limited. In many cases, donkeys and mules are treated like horses, with the physiological differences between these species usually not taken into account. Most infectious diseases that affect the Equidae family are exclusive to the family, and they have a tremendous economic impact on the equine industry. However, some viruses may cross the species barrier and affect humans, representing an imminent risk to public health. Nevertheless, even with such importance, most studies are conducted on horses (Equus caballus), and there is little comparative information on infection in donkeys and mules. Therefore, the objective of this article is to provide a brief update on viruses that affect donkeys and mules, thereby compromising their performance and well-being. These diseases may put them at risk of extinction in some parts of the world due to neglect and the precarious conditions they live in and may ultimately endanger other species’ health and humans.

“…The incidence of EVA has been increasing especially in the last two decades (Glaser et al 1997;Rola et al 2011). According to the latest reports, the virus is in circulation in different parts of the world like Poland (Rola et al 2011), Algeria (Laabassi et al 2014), France (Amat et al 2016), Spain (Cruz-Lopez et al 2017), Serbia (Lazić et al 2017) and Chile (Rivas et al 2017).

Serological investigation of equine viral arteritis in donkeys in eastern and south-eastern Anatolia regions of Turkey

et al. 2019

Equine arteritis virus is classified in the Arteriviridae family and causes reproductive and respiratory disorders. The host spectrum includes many species of the Equidae family. Horses, donkeys and mules are the most sensitive species. The infection was serologically investigated in adult donkeys on small private family type enterprises in eastern and south-eastern Anatolia in this study. A total of 1,532 samples were collected from 28 different locations in 6 different provinces in these two regions. The number of donkeys sampled from each farm was between 1 and 3. Serum samples were tested by indirect enzyme-linked immunosorbent assay (ELISA). As a result of sero-controls, 53 animals were positive (3.45%). The presence of infection was determined in all the provinces; Elazığ (7%, 17/241), Tunceli (2.4%, 3/122), Van (2.9%, 10/342), Bitlis (4.6%, 5/107), Şırnak (2.7%, 12/440) and Siirt (2.1%, 6/280). Seropositivity was detected in 22 of the 28 locations. In this study, data were obtained from a significant number of animals for the first time in these regions. Although the values were not high, the findings revealed the presence of infection in the majority of the investigated sites. Despite the fact that the incidence was not high in donkeys probably due to restricted management conditions, the incidence may increase over time and may pose a risk for thoroughbred horses unless necessary measures are taken.

An Overview of Infectious and Non-Infectious Causes of Pregnancy Losses in Equine

Equine breeding plays an essential role in the local economic development of many countries, and it has experienced rapid growth in China in recent years. However, the equine industry, particularly large-scale donkey farms, faces a significant challenge with pregnancy losses. Unfortunately, there is a lack of systematic research on abortion during equine breeding. Several causes, both infectious and non-infectious, of pregnancy losses have been documented in equines. The infectious causes are viruses, bacteria, parasites, and fungi. Non-infectious causes may include long transportation, ingestion of mycotoxins, hormonal disturbances, twinning, placentitis, umbilical length and torsion, etc. In current review, we discuss the transmission routes, diagnostic methods, and control measures for these infectious agents. Early detection of the cause and appropriate management are crucial in preventing pregnancy loss in equine practice. This review aims to provide a comprehensive understanding of the potential causes of abortion in equines, including infectious agents and non-infectious factors. It emphasizes the importance of continued research and effective control measures to address this significant challenge in the equine industry.
