“…Penyakit BEF merupakan penyakit vectorborne disease, ditransmisikan melalui vektor serangga yang banyak terdapat di daerah tropis dan subtropis seperti Asia, Afrika dan Australia. Kejadian BEF dipengaruhi oleh beberapa faktor seperti adanya bendungan air (Yeruham et al, 2010), sistem irigasi yang kurang baik (Bett et al, 2017), perubahan lingkungan, cuaca dan iklim (Kasem et al, 2014;Mirzaie et al, 2017), perpindahan ternak (Murray, 1997), vektor (Mellor, 1996: Thomson andConnor 2000) dan mekanisasi pertanian (Sutherst, 2004). Kejadian BEF bersifat musiman di daerah beriklim sedang sehingga sebagian besar kasus dilaporkan pada akhir musim panas dan musim gugur (Yeruham et al, 2010).…”

Bovine ephemeral fever (atau 3-day sickness) adalah penyakit demam akut pada sapi dan kerbau yang disebabkan oleh Ephemerovirus dari keluarga rhabdoviridae dan ditularkan oleh vektor arthropoda. Penyakit tersebut biasa terjadi di daerah tropis dan subtropis. Dalam banyak kasus, dampak utamanya adalah pada penurunan produktivitas, produksi susu, kondisi tubuh, gangguan reproduksi, dan periode pemulihan yang lama pada beberapa hewan. Gejala klinis bervariasi pada setiap individu hewan, tetapi pada umumnya diawali dengan demam yang bersifat bifasik melanjut menjadi polifasik. Mortalitas biasanya rendah, namun, peningkatan kasus berakibat fatal telah dilaporkan dalam beberapa wabah akhir-akhir ini. Penyakit ini tersebar luas diberbagai daerah di Indonesia. Secara umum tidak menimbulkan kerugian ekonomi yang besar, asalkan segera mendapatkan pertolongan medis yang memadai sehingga tidak terjadi komplikasi dengan penyakit lain. Tulisan ini bertujuan untuk mengulas penyebab, metode diagnosa, dan terapi yang dapat dilakukan untuk menanggulangi kejadian BEF.

“…A virological survey carried out from August 2010 to June 2011 in Khuzestan Province of Iran showed positive rates of 29% in cattle and 17% in buffalo, suggesting that BEFV infection is prevalent at least in western Iran [4]. An outbreak in 2013 resulting in a mortality of 464 cattle was reported [37].…”

“…Australia’s BEFVs are likely to circulate as an independent ecosystem to those of Asian countries. Nevertheless, based on the experiences of international transmission of bluetongue virus strains between northern Australia and southeastern Asian countries [38,48], it is possible for arthropod-borne viruses such as bovine ephemeral fever to be transmitted in the same way, although no virus isolate has shown evidence of this possibility [37].…”

Bovine ephemeral fever is an arthropod-borne viral disease affecting mainly domestic cattle and water buffalo. The etiological agent of this disease is bovine ephemeral fever virus, a member of the genus Ephemerovirus within the family Rhabdoviridae. Bovine ephemeral fever causes economic losses by a sudden drop in milk production in dairy cattle and loss of condition in beef cattle. Although mortality resulting from this disease is usually lower than 1%, it can reach 20% or even higher. Bovine ephemeral fever is distributed across many countries in Asia, Australia, the Middle East, and Africa. Prevention and control of the disease mainly relies on regular vaccination. The impact of bovine ephemeral fever on the cattle industry may be underestimated, and the introduction of bovine ephemeral fever into European countries is possible, similar to the spread of bluetongue virus and Schmallenberg virus. Research on bovine ephemeral fever remains limited and priority of investigation should be given to defining the biological vectors of this disease and identifying virulence determinants.

“…BEF disease is prevalent in Middle East countries and is considered an enzootic disease in some areas of this region [4,12]. The rst detailed report of BEF in the Middle East was described in Egypt in 1909, in which the disease spread from Aswan, Nile Valley to Cairo, and spread across the Delta to the coast [11].…”

“…The disease is marked by a bi-phasic or multiple-phasic fever, anorexia, muscle stiffness, salivation, depression, lameness, ocular and nasal discharge, cessation of rumination, and constipation [3]. BEF causes considerable economic losses, mainly because of its consequences and imposing international trade restrictions [4,5]. BEF, caused by an arthropod-borne virus, usually occurs in the summer and early autumn months [3].…”

Background Bovine ephemeral fever (BEF) is an arthropod-borne viral disease caused by the BEF virus (BEFV). This single-stranded RNA virus that affects cattle and water buffalo is endemic in tropical and subtropical regions including Iran. While BEF is a major disease of cattle in Iran, information regarding its agent, molecular characterization, and circulating viruses are highly limited. The current study aimed to, firstly, determine the genetic and antigenic characteristics of BEFV strains in Khuzestan province in Southwest of Iran from 2018 to 2020 and, secondly, to compare them with strains obtained from other areas. Results By phylogenetic analysis based on the Glycoprotein gene, BEFV strains were divided into four clusters of Middle East, East Asia, South Africa, and Australia; in which the 2018 and 2020 Iranian BEFV strains were grouped in the Middle East cluster with the Turkish, Indian, and Israeli strains. Depending on the chronology and geographical area, the outbreaks of Turkey (2020), Iran (2018 and 2020), and India (2018 and 2019) are proposed to be related. These BEFVs had the highest identity matrix and the lowest evolutionary distance among the studied strains. Multiple sequence alignment of G1, G2, and G3 antigenic sites showed that these neutralizing epitopes are highly conserved among the strains of the Middle East cluster; however, the strains previously identified in Iran differed in three amino acids placed in G1 and G2 epitopes. Conclusion The findings revealed that BEFVs circulating in the Middle East are closely related phylogenetically and geographically. They also have similar antigenic structures; therefore, developing a vaccine based on these strains can be effective for controlling BEF in the Middle East.
