| genotypic diversity of theileria orientalis detected from cattle grazing in kumamoto and okinawa prefectures of japan. | theileria orientalis is a benign protozoan species that is widely distributed in japan, yet sometimes causes serious economic losses in the livestock industry. in this study, we conducted a molecular survey based on genes encoding the major piroplasm surface protein (mpsp) and p23 for t. orientalis detected in cattle grazing in southern areas of japan, consisting of 2 farms in kumamoto prefecture (aso and kuma districts) and 3 farms in okinawa prefecture (ishigaki, iriomote, and yonaguni islands ... | 2010 | 20978366 |
| morphological survey of bovine setaria in the abdominal cavities of cattle in aomori and kumamoto prefectures, japan. | an epidemiological survey of bovine setaria collected from the abdominal cavities was performed morphologically on the cattle in aomori and kumamoto prefectures, japan, between august 2005 and july 2006. fifty setaria worms were collected from the cattle in aomori prefecture and 847 from those in kumamoto prefecture. of these worms, 35 were identified as setaria digitata, 14 as s. marshalli, and one as s. labiatopapillosa in aomori prefecture, while 816 were identified as s. digitata and 31 as s ... | 2007 | 17485931 |
| comparison of genetic gains per year for carcass traits among breeding programs in the japanese brown and the japanese black cattle. | the breeding program for beef cattle in japan has changed dramatically over 4 decades. visual judging was done initially, but progeny testing in test stations began in 1968. in the 1980s, the genetic evaluation program using field records, so-called on-farm progeny testing, was first adopted in oita, hyogo, and kumamoto prefectures. in this study, genetic trends for carcass traits in these 3 wagyu populations were estimated, and genetic gains per year were compared among the 3 different beef cat ... | 2006 | 16424259 |
| reduction in tick numbers (haemaphysalis longicornis), mortality and incidence of theileria sergenti infection in field-grazed calves treated with flumethrin pour-on. | the effectiveness of the pour-on formulation of flumethrin was tested on grazing cattle. flumethrin was applied once a month from april to october from 1990 to 1995 to cattle grazing in the aso area of kumamoto prefecture in japan. both the number of ticks in the field and the number of ticks feeding on cattle decreased remarkably in relation to the number of years flumethrin was applied. ticks in the field were not detected in 1994 and 1995, and ticks feeding on cattle decreased to 4% in 1995. ... | 2000 | 10946136 |
| a polymorphism observed in the experimentally successful peptide vaccine sequence derived from theileria sergenti piroplasm major surface antigen (p33). | a polymorphism in the experimentally successful peptide vaccine sequence (evvwkekkevkdlda, amino acids 134-148) derived from the 33 kda piroplasm major surface antigen (p33) of theileria sergenti was examined. the vaccine sequences obtained by pcr amplification and sequencing of the p33 gene from a total of 15 parasite-infected cattle blood samples collected from 4 prefectures through hokkaido to kumamoto revealed the two major sequences (ikeda and chitose stock types) either of which was identi ... | 1997 | 9342711 |
| investigation of culicoides (diptera: ceratopogonidae) in relation to the transmission of bovine onchocerca and other filariae in central kyushu, japan. | in kyushu, japan, where a human case of zoonotic onchocerciasis was found, a survey was conducted to know if the bovine onchocerca species of this region, o. gutturosa, o. lienalis and o. sp., which develop in local simulium spp., were also transmitted by culicoides. a total of 17,006 out of 42,582 females of eight culicoides species captured by light-traps from may to november in 1989 and 1990 at two cattle sheds, one in oita and one in kumamoto, were dissected and examine for onchocerca infect ... | 1995 | 8745737 |
| congenital anophthalmia with caudal vertebral anomalies in japanese brown cattle. | anophthalmia and caudal vertebral anomalies such as taillessness or wry tail were morphologically examined in ten japanese brown calves obtained in kumamoto prefecture. the anomalous calves lacked eyeball bilaterally or unilaterally but had small-sized eyelids and narrow palpebral fissures. a small cystic, solid or spot-like remnant of eyeball (reb) was buried in the mixture of vestigial extraocular muscles, lacrimal gland and adipose tissue of the orbit. the reb was composed of irregularly arra ... | 1995 | 8519900 |
| natural vectors of three bovine onchocerca species (nematoda: onchocercidae) and seasonal transmission by three blackfly species (diptera: simuliidae) in central kyushu, japan. | eleven blackfly species were examined in relation to the transmission of bovine onchocerciasis in central kyushu, japan. a total of 19,005 out of 47,746 females captured from june 1989 to june 1990 at two cattle sheds each in oita and kumamoto were dissected for their parities, infections with onchocerca larvae, and intakes of onchocerca microfilariae. overall results showed that simulium bidentatum (shiraki), the predominant species, is a natural vector of the two bovine onchocerca species, i.e ... | 1994 | 8057315 |
| 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 |
