The aim of the present study was to investigate whether Bovine Spongiform Encephalopathy (BSE) is present in this country and to analyze the Global BSE Risk (GBR) status in Bangladesh. A total of 2,000 brain samples were collected from cattle older than 30 months of age, slaughtered for human consumption in the district slaughter houses from 2005 to 2006. The brainstem (obex), Pyriform lobe, cerebrum and cerebellum were subjected to histopathological study. Samples that showed some nonspecific lesions were subjected to immunohistochemistry and only brain stem to ELISA for the detection of abnormal prion protein PrPsc. In passive surveillance, annual overall diseases of cattle, buffalo, sheep and goats in Bangladesh were collected from Department of Livestock Services (DLS), Dhaka to investigate the occurrences of neurological diseases. Import related data were collected from “National Export Promotion Bureau” Kawran Bazar, Bangladesh Bank and DLS to analyze the importing products of animal origin (cattle, buffalo, sheep and goats) from different countries to find whether or not the imported products posed any risk for the BSE. In an actire surveillance conducted in slaughter house, histopathologically BSE specific lesions were not detected in any of the brain samples, but other nonspecific lesions were observed. No PrPsc was detected from the samples by immunohistochemistry and ELISA. DLS report also supported the absence of BSE in cattle and buffalo and scrapie in sheep and goats in Bangladesh. It was also clearly recorded that Bangladesh imported livestock products from countries in GBR level I and II but not from countries in GBR level III and IV. From this study it apparently seems that BSE is not currently present in the indigenous animals in Bangladesh and poses no or negligible risk to human and animal health.

BSE (bovine spongiform encephalopathy)-like symptoms salivation, gait disorder, and the downer syn-drome occurred to 8 heads of cattle at six cattle farms in Gyeonju, east eastern Gyeongsang province in 2013. Eight brain tissue samples using a vibration saw (Multimaster^® FEIN, Germany) were collected referring to The brain removal technique of transmisible spongiform encephalopathy sampling DVD by Animal And Plant Quarantine Agency. Brain removal techinque using a vibration saw on the thick, solid frontal bone of cattle is more convenient for incision and removal than an ax for BSE testing.

The Effect of Lost Exports caused by BSE Outbreak on U.S. Beef Prices

( Hyun Joung Jin ) 한국농업경제학회 2006 KOREAN JOURNAL OF AGRICULTURAL ECONOMICS(KJAT) Vol.47 No.3

A case of bovine spongiform encephalopathy (BSE), commonly referred to as mad.cow disease, was discovered in US Washington state on December 23, 2003. The outbreak led to bans on imports of U.S. beef in a number of important markets, including Japan and South Korea. U.S. beef exports, therefore, declined significantly in 2004. This study examines exports and other demand.supply factors on U.S. meat prices to analyze the BSE effects. Results indicate that if all other factors remain the same, the drop in beef exports results in a 22 cent per pound reduction in retail beef prices. Prices in 2004 remained relative high, however, possibly due to a decline in U.S. production and strong domestic demand.

Risk Analysis of Bovine Spongiform Encephalopathy in Korea

<P>The occurrence of Bovine Spongiform Encephalopathy (BSE, so called mad cow diseases) that was first identified in England in 1986 was considered as being limited to only European countries, including England. However, the outbreak in Asia as well as North America since 2001 has amplified the fear that there isn't any nation in the world that is a safe area. In order to assess the risk of BSE outbreak in each country, the Office International des Epizooties (OIE) and EU have respectively established criteria, where OIE has set 5 levels and EU has set 4 levels. The Scientific Steering Committee (SSC) of the European Commission conducted a Geographical BSE Risk(GBR) assessment for 64 nations, such as the United States, etc., as of April 29, 2003. However, as of July 1, 2005, the duty of GBR assessment is expected to be transferred to a newly established body called EFSA (European Food Safety Authority, located in Parma, Italy). As Korea has not undergone a GBR assessment up to now, this study analyzed the risk of BSE outbreak in Korea by reviewing BSE prevention measures, etc., that have been put in place. This study shall be a barometer for estimating the GBR assessment level of Korea.</P>

Sequence variations of the bovine prion protein gene (PRNP) in native Korean Hanwoo cattle

Sangho Choi,우희종,이정민 대한수의학회 2012 Journal of Veterinary Science Vol.13 No.2

Bovine spongiform encephalopathy (BSE) is one of the fatal neurodegenerative diseases known as transmissible spongiform encephalopathies (TSEs) caused by infectious prion proteins. Genetic variations correlated with susceptibility or resistance to TSE in humans and sheep have not been reported for bovine strains including those from Holstein,Jersey, and Japanese Black cattle. Here, we investigated bovine prion protein gene (PRNP) variations in Hanwoo cattle [Bos (B.) taurus coreanae], a native breed in Korea. We identified mutations and polymorphisms in the coding region of PRNP, determined their frequency, and evaluated their significance. We identified four synonymous polymorphisms and two non-synonymous mutations in PRNP, but found no novel polymorphisms. The sequence and number of octapeptide repeats were completely conserved, and the haplotype frequency of the coding region was similar to that of other B. taurus strains. When we examined the 23-bp and 12-bp insertion/deletion (indel) polymorphisms in the non-coding region of PRNP, Hanwoo cattle had a lower deletion allele and 23-bp del/12-bp del haplotype frequency than healthy and BSE-affected animals of other strains. Thus, Hanwoo are seemingly less susceptible to BSE than other strains due to the 23-bp and 12-bp indel polymorphisms.

The purpose of the current research is to identify the BSE(Bovine Spongiform Encephalopathy) impact on economy of Korea meat market. After the outbreak of ESE in North America. the restriction of beef import from this area have caused beef supply decrease that have had fuJJ imρact on restaurant industry in Korea. To achieve the purpose of this research, the research conducts an empirical study to investigate how and what the restaurateurs have perceived the secondary effect of restriction of North American beef import. 174 individuaJly owned restaurants were voluntarily participated for this interview survey. The results discussed several issues regarding beef cost. changed features of beef import. restaurateurs various responses against the ban on North American beef import.

프리온 질환과 어류의 관련성에 관한 연구 동향

Transmissible spongiform encephalopathies (TSEs), also termed prion diseases, are a threat to food safety and to hu- man and animal health. Variant Creutzfeldt-Jakob disease (vCJD) in humans is caused by the consumption of meat contaminated with bovine spongiform encephalopathy (BSE, mad cow disease). The BSE epidemic in the United Kingdom was shown to be related with the extensive use of BSE-contaminated meat-and-bone meal (MBM) and bovine offal. Many countries worldwide use MBM, as well as meat from cows, for aquaculture feed. This raises concerns about the safety of farmed fish, a major protein source for humans. The present work reviews recent studies on fish prion protein and the transmissibility of mammalian prion agents to fish, providing insights into the future direction of fish prion research.

프리온 그리고 광우병과 변형 크로이츠펠트 야콥병(인간광우병)간의 유관성

A significant concern about the potential that many Korean may be infected with variant Creutzfeldt-Jakob disease (vCJD) through ingestion of cow meat has been increasing by leaps and bounds in all over the Korea, along with the reopening import of cow meat from United States again this year. Therefore, this review is aimed to provide right information about prion characteristics and introduce new insights into the pathogenesis of vCJD. Finally, the prophylactic policy to interrupt transmission routes from Bovine spongiform encephalopathy (BSE) to vCJD was suggested on the basis of the previous reports about BSE and vCJD.
