“…In Australia, AINOV was also isolated (110,111) and its association with congenital abnormalities was reported (112). Shuni virus, which is closely related with AINOV and distributed in Africa and the Middle East, caused abortions and congenital malformations in sheep, goat, and cattle (113), and neurological disorders in cattle (114).…”

Endemic and Emerging Arboviruses in Domestic Ruminants in East Asia

2020

Epizootic congenital abnormalities caused by Akabane, Aino, and Chuzan viruses have damaged the reproduction of domestic ruminants in East Asia for many years. In the past, large outbreaks of febrile illness related to bovine ephemeral fever and Ibaraki viruses severely affected the cattle industry in that region. In recent years, vaccines against these viruses have reduced the occurrence of diseases, although the viruses are still circulating and have occasionally caused sporadic and small-scaled epidemics. Over a long-term monitoring period, many arboviruses other than the above-mentioned viruses have been isolated from cattle and Culicoides biting midges in Japan. Several novel arboviruses that may infect ruminants (e.g., mosquito-and tick-borne arboviruses) were recently reported in mainland China based on extensive surveillance. It is noteworthy that some are suspected of being associated with cattle diseases. Malformed calves exposed to an intrauterine infection with orthobunyaviruses (e.g., Peaton and Shamonda viruses) have been observed. Epizootic hemorrhagic disease virus serotype 6 caused a sudden outbreak of hemorrhagic disease in cattle in Japan. Unfortunately, the pathogenicity of many other viruses in ruminants has been uncertain, although these viruses potentially affect livestock production. As global transportation grows, the risk of an accidental incursion of arboviruses is likely to increase in previously non-endemic areas. Global warming will also certainly affect the distribution and active period of vectors, and thus the range of virus spreads will expand to higher-latitude regions. To prevent anticipated damages to the livestock industry, the monitoring system for arboviral circulation and incursion should be strengthened; moreover, the sharing of information and preventive strategies will be essential in East Asia.

“…On the other hand, the antigenicity of strain B7974 isolated from Culicoides brevitarsis in Australia in 1968 (4) was highly different from those of isolates in Japan. Strains JaNAr28 and B7974 were indistinguishable by cross neutralization, cross hemagglutination-inhibition, and cross complement fixation tests (17). However, DIAs with these MAbs which defined epitopes to the Aino virus clearly revealed the differences in antigenicities of strains JaNAr28 and B7974.…”

Comparison of Intertypic Antigenicity of Aino Virus Isolates by Dot Immunobinding Assay Using Neutralizing Monoclonal Antibodies

et al. 2000

Neutralizing monoclonal antibodies (MAbs) against the Aino virus were prepared, and the neutralizing epitopes of the virus were defined by competitive binding assay. Seven continuous and overlapping neutralizing epitopes existed on the G1 glycoprotein of the Aino virus. Two antigenic domains were identified and were designated I and II, with domain II consisting of six epitopes. Dot immunobinding assays (DIAs) were performed with MAbs that recognized these seven neutralizing epitopes. DIAs were performed with 1 Australian strain and 21 isolates found in Japan between the years 1964 and 1995. The MAb response patterns of all isolates were divided into four groups. The Japanese isolates did not show large differences in antigenicity, but the antigenicity of the Australian strain collected in 1968 was significantly different from that of the Japanese strains; the Australian strain lacked reactivity to three epitopes and showed only low reactivity to one epitope.

“…Miura et al (1974) and Kurogi et al (1975) studied the incidence of neutralizing antibody to Aino virus in calves and cows with congenital arthrogryposis-hydranencephaly (AH) syndrome and reported that 2 of 20 (Miura et al, 1978) and 2 of 52 (Kurogi et al, 1975) calves had antibody to the virus.…”

“…Miura et al (1978) showed that this virus is serologically identical with Samford virus, which was isolated from Culicoides brevitarsis in Australia (Doherty et al, 1972 The serum samples were obtained from apparently healthy 1-3 years old animals and from 1-74 years old humans who had lived in Fukuoka Prefecture for more than one year. All serum samples were stored at -20 C and thawed just before the neutralizing test.…”
