theoretical epidemiology on bovine ephemeral fever outbreaks in tanegashima island, kagoshima prefecture of japan in 1988.	from the end of september to november 1988, a compact scale of bovine ephemeral fever (bef) outbreaks occurred suddenly in tanegashima island of kagoshima prefecture, southern part of kyusyu island of japan. the bef outbreak pattern showed epidemical characteristics as follows; (1) outbreak spread from few foci to zone during one month, and (2) the disease might be transmitted in farms with a fixed probability of adequate contact. by using the above aspects, we attempted to analyze the disease t ...	1992	1420574
[japanese encephalitis virus infection in cattle: a serological survey in saitama and kagoshima prefectures].	serum samples were collected from a total of 1,306 and 536 cattle raised in saitama and kagoshima prefectures, respectively, during a period from 1982 to 1984. their antibody titers against japanese encephalitis virus (jev) were determined by the hemagglutination-inhibition test. antibody prevalences were 65.5% (856/1306) and 68.8% (369/536) in saitama and kagoshima prefectures, respectively. in both prefectures, there was a rapid increase in positive rate and mean titer in summer. afterwards, t ...	1989	2545797
isolation and preliminary characterization of an orbivirus of the palyam serogroup from biting midge culicoides oxystoma in japan.	an orbivirus of the palyam serogroup was isolated from culicoides oxystoma collected in a cowshed in kagoshima, southern kyushu island, japan. this is the first isolation of an orbivirus of the palyam serogroup in japan. the virus was a spherical non-enveloped rna virus, approximately 60 nm in diameter. the virus was resistant to ethyl ether, sodium deoxycholate and freezing-thawing, but readily inactivated by trypsin. the virus was not stabilized by 1 m mgcl2, was labile at ph 3.0 and was not p ...	1989	2646823
a survey of neutralizing antibody against aino virus in bovine serum in kagoshima, japan.		1980	7432549
a congenital abnormality of calves, suggestive of a new type of arthropod-borne virus infection.	about 1000 calves with a congenital disease were born in kagoshima prefecture, japan, between october 1990 and october 1991, the peaks of the epidemic being in march and july 1991. of 85 abnormal calves examined pathologically and serologically, 70 appeared to have been suffering from a viral disease. of these 70 animals, 17 had lesions bearing some resemblance to those of the diseases produced by akabane, chuzan, aino, bluetongue and bovine viral diarrhoea-mucosal disease viruses-diseases known ...	1994	7884059
rumen ciliate composition and diversity of japanese beef black cattle in comparison with those of holstein-friesian cattle.	the composition of ciliate protozoa in the rumen of 30 japanese beef black cattle (bos taurus taurus) fed in yoron island, kagoshima, was compared with that of 125 holstein-friesian cattle (bos taurus taurus) fed in hokkaido. thirteen genera including 44 species with 32 formae detected from japanese beef black cattle and 15 genera including 48 species with 25 formae from holstein-friesian cattle were identified. thirty-six species with 19 formae were common to both hosts. a new species was recog ...	1994	7999896
identification of kagoshima and chuzan viruses of japan as kasba virus, an orbivirus of the palyam serogroup.		1994	8166617
prevalence of calf diarrhea caused by bovine group a rotavirus carrying g serotype 8 specificity.	one hundred and seventeen rectal fecal specimens were collected in 1995 and 1996 from calves with diarrhea in kagoshima prefecture in japan. the bovine group a rotavirus was detected by enzyme immunoassay in 43 of 117 specimens and isolated from 33 of the 43 specimens that were positive. g serotype, p serotype, and p genotype of 33 isolates were identified by reverse transcription-polymerase chain reaction, and 20 of 33 isolates (60.6%) were identified as g serotype 8. thus, we discovered that c ...	1999	10384891
changes in the prevalence of rotavirus g and p types in diarrheic calves from the kagoshima prefecture in japan.	g8 bovine group a rotavirus was the most predominant serotype in calf diarrheal fecal specimens examined between 1995 and 1996 in japan [vet. microbiol. 66 (1999) 301]. to date, no evidence that g8 was the most predominant in the typeable specimens has been observed outside japan. to investigate whether g8 continues to be as common as g6 and g10, the incidence of the main serotypes was determined in the same area (kagoshima prefecture) between 1997 and 1998 by reverse transcription-polymerase ch ...	2002	11955784
the resurgence of shamonda virus, an african simbu group virus of the genus orthobunyavirus, in japan.	six virus isolations were made from culicoides biting midges and blood samples of sentinel cattle in kagoshima and miyazaki prefectures, the southern part of japan, in 2002. serological and genetical tests identified these viruses as isolates of shamonda virus (shav), which belongs to the simbu group of the genus orthobunyavirus of the family bunyaviridae. initially, shav was isolated from cattle and culicoides biting midges in nigeria in the 1960s, and its presence has not been reported until t ...	2005	15503217
isolation of bovine arboviruses from culicoides biting midges (diptera: ceratopogonidae) in southern japan: 1985--2002.	in 1985--2002, surveillance for bovine arboviruses was conducted in kagoshima, located in the most southern part of the main islands of japan and known to be an area where bovine arboviral diseases have frequently been epidemic. culicoides biting midges were collected in a cowshed by light traps. a total of 456,300 culicoides biting midges representing 13 species were collected, and a portion of each pool of midges were tested for virus isolation. overall, 85 isolates of six different viruses we ...	2005	15691010
detection of culicoides brevitarsis activity in kyushu.	culicoides brevitarsis transmits important ruminant arboviruses, such as akabane, aino and bluetongue viruses. the presence of this species has so far been recognized primarily in okinawa, the southernmost prefecture of japan. in entomological surveys in 2008 and 2009, c. brevitarsis was collected at 8 sites throughout nagasaki, kumamoto and kagoshima prefectures. the collection sites are all located near pastures, where the larvae of c. brevitarsis can grow in cattle dung left in the field. c. ...	2011	21799296
