“…(Kono et al, 2008;Elliott et al, 1990;Kim et al, 2011;Kurogi et al, 1987;Farag et al, 1998). Neutralizing antibodies against BEFV has also been reported in many countries in buffalo, sheep and cattle and is highly variable depending on the age and immune status of ruminants (Farag et al, 1998;Zheng et al, 2010;Jun et al, 2012). Our sero-monitoring after massive Akabane and BEF outbreaks reveals that the overall seropositive rates against AKAV and BEFV are moderate (49.8%) and very low (1.2%), respectively.…”

“…Epizootic of Arboviruses such as AKAV and BEFV is associated with host factors such as health condition and population immunity, and seasonal conditions such as temperature, humidity, and activity of haematophagous vectors (Hsieh et al, 2005;Lim et al, 2007;Jun et al, 2012). Summer season (June to August) is suitable for proliferation and activity of haematophagous vectors in Korea.…”

Since a large number of Akabane and bovine ephemeral fever (BEF) infection occurred in the southern part of Korea in 2010, recent information about seroprevalence of Akabane virus (AKAV) and bovine ephemeral fever virus (BEFV) has been required for preventing both diseases. In this study, serological assay against AKAV and BEFV using virus neutralization assay was conducted using 1,743 bovine sera collected from Namwon, Miryang, Yeongju and Uljin which located in Southern part of Korea from March to May in 2012. The overall seropositive rates for AKAV and BEFV were found to be 49.8% and 1.2%, respectively. The regional distribution of seroprevalence for AKAV ranged from 18.1% to 63.7%. Seroprevalences of AKAV were 63.7% in Miryang, 62.3% in Uljin, 50.7% in Namwon, and 18.1% in Yeongju. The seropositive rates for AKAV in southern part of Korea were higher than the annual average at the national level. On the other hand, seropositive rates of BEFV in four regions were from 0.3 to 3.1%. In detail, regional seroprevalences were 3.1% in Miryang, 2.0% in Uljin, and 1.7% in Yeongju, and 0.3% in Namwon. Even only one year after massive outbreaks, overall seropositive rates were very low, similar to the annual average at the nation level. This result indicates that many number of cattle infected with BEFV may be replaced by new born calf or cattle in farm may not be immunized with vaccines. To prevent another epidemic, a national wide warning should be issued and more aggressive control measure must be implied. Recent global warming phenomenon could lead to more vigorous activity of haematophagous vectors and it is possible that arboviral diseases such as AKAV and BEFV are increased. Therefore, continuous sero-monitoring and extensive vaccination combined with control of haematophagous vectors are important to effectively prevent and control diseases caused by AKAV and BEFV.

“…The present study reports that despite similar etiological features between SBV and AKV, both viruses have distinct selection profiles and the strength of selection is likely to be time-dependent. The estimated mutation rate and the overall x of the recently emerged SBV are considerably higher than those estimates of AKV, which has been causing sporadic outbreaks in ruminant populations across the temperate and tropical regions since 1970s (Geoghegan et al, 2014;Jun et al, 2012;Kessell et al, 2011;Kono et al, 2008;Lee et al, 2007;Oem et al, 2014Oem et al, , 2012Yamakawa et al, 2006). Such discrepancies could possibly be attributed to the differences in the timing of emergence of these two infectious viral pathogens.…”

“…Although both viruses have similar etiological features and host range, they exhibit distinct geographical distributions and emerge at different time points. While AKV is relatively older and has been causing sporadic outbreaks in the cattle industries across Asia, Australia, and Africa since 1970s (Geoghegan et al, 2014;Jun et al, 2012;Kessell et al, 2011;Kono et al, 2008;Lee et al, 2007;Oem et al, 2014Oem et al, , 2012Yamakawa et al, 2006), SBV was first reported in autumn 2011 in Germany (Hoffmann et al, 2012) and subsequently, spread across most of the European countries Chaintoutis et al, 2014;Doceul et al, 2013;Dominguez et al, 2014;Herder et al, 2012;van den Brom et al, 2012;Yilmaz et al, 2014). The two viruses have similar genomic features with three genomic segments, small (S), medium (M) and large (L) (Fischer et al, 2013).…”

A b s t r a c tAkabane disease, a transmissible pathology of cattle, sheep and goats, is caused by Simbu serotype virus (Bunyaviridae) and results in significant economical losses due to abortions, unviable and abnormal calves, or dead embryos and calves born. The Akabane disease epizooties, characterized by geographic locations and the coincidence with definite seasons, are widely registered. For preparative accumulation of Akabane virus the 1-2 day mice are used as the most sensitive system for Bunyaviridae isolation. Earlier we reported the development of a test system for Akabane virus RNA indication by real time reverse transcription PCR. Its efficacy was approved using infected mice and cell cultures. Furthermore, it was of interest to estimate this test system with respect to more wide range of model animals to be involved in the study and reproduction of Akabane virus. In this investigation, healthy cavies (n = 20, the animal weight of 400 g) were infected with a concentrated viral culture (B8935 strain) of 7.0 lg TCID 50 /cm 3 . In blood the Akabane virus RNA was detected in four animals only 4 days after inoculation, but not shown in the rest probes, which were sampled from 2 to 6 days, and one cavy died a day after infection, probably due to nonspecific reaction as the Akabane virus genome was not detected in the post mortem tissue samples of all the organs of the animal tested. After 4 days the Akabane virus RNA was also indicated in brain, lung, kidney, hart and lymphatic gland. Thus, the developed test-system is effective for Akabane disease diagnosis, and the experimentally infected cavies can be the model animals used to study and produce Akabane virus preparations.
