African swine fever (ASF) is a contagious viral disease in pigs and wild boars which poses major threat to the pig industry. Rapid accurate diagnosis necessary control ASF. Hence, we developed rapid diagnostic method using recombinase polymerase amplification (RPA) assay targeting conserved sequences of CP204L (p30) thatcan rapidly detect ASF virus (ASFV) genotype strains I II. The lower detection limit real-time RPA was 5 × 101 copies per reaction. effectively detected ASFV isolates...
A majority (>70%) of Q fever patients in South Korea do not have a history animal contact. Therefore, unconscious environmental exposure is suspected. The aim this study was to investigate contamination and shedding.Two goat farmers were enrolled. One diagnosed with 3 years ago (Farm 1). Among 20 goats on Farm 1, five tested randomly found be PCR-positive. Three the ELISA-positive. Two samples taken 2015 In 2018, 17 18 On 2, 54 77 PCR-positive, 63 Twelve 14 Repeat administration...
Tick-borne diseases are a public health problem and significant burden on the livestock industry. The seasonal abundance of ticks tick-borne pathogens strongly correlates with prevalence these diseases. To investigate variation in pathogens, were collected from Gangwon State, Korea, Borrelia, Anaplasma, Babesia, Theileria examined. In total, 14,748 collected, comprising two genera three species: Haemaphysalis longicornis, flava, Ixodes nipponensis, H. longicornis being predominant species....
Mycobacterium bovis strain 1595 was isolated from the lymph node of South Korean native cattle. The complete genome sequence determined in 2 contigs and found to be 4,351,712 bp size, with a 65.64% G+C content 4,358 predicted protein-coding genes.
Mycobacterium (M.) bovis, a bacterium in the M. tuberculosis complex, is causative agent of bovine tuberculosis, contagious disease animals.Mycobacterial culture gold standard for diagnosing but this technique laborious and time-consuming.In present study, performance SD Bioline TB Ag MPT4 Rapid test, an immunochromatographic assay, was evaluated using reference bacterial strains bovis field isolates collected from animals.The MPT64 test produced positive results 95.5% (63/66) cattle 97.9%...
We report a massive outbreak of human Q fever cases, which occurred at totally 11 humans. The occurrence was related to goat farm where Coxiella burnetii infection diagnosed from tissues and environmental specimens. From January 2018, continuous abortions 6 goats occurred. Laboratory tests 77 specimens for C. showed that 54 (70.1%) 63 (81.8%) were positive by polymerase chain reaction (PCR) enzyme-linked immunosorbent assay (ELISA), respectively. also confirmed the farmer, his wife 9 persons...
African swine fever (ASF) is a contagious, hemorrhagic and highly lethal viral disease in swine. Following the initial report of ASF Kenya 1921 it spread to East Asia through Western Europe Russia (including Eastern Europe). Many efforts have been dedicated controlling but struggle eradicate this continues. Thus far, develop an effective vaccine control unsuccessful. A previous inactivated vaccine, developed by traditional methods, failed protect pigs from virus (ASFV) infection....
Probiotics have many effects such as antihypertensive, prevention of cancer, antioxidation, reduction dermatitis symptoms, improvement mineral absorption, allergic and decrease cholesterol, However, the main role probiotics is that they balance intestinal microbials proportion. L. acidophilus one microflora in intestine. It has an acidification activity, aroma production, texture formation properties. We studied on roles mice. In this study, body weights mice were decreased when...
The dried root of Angelica gigas (A. gigas) has been traditionally used as an oriental medicine, which is known to improve blood circulation and stasis. In the present study, leaves stalks A. were investigate their effects on innate immunity. extracts prepared from fed mice. numbers cells, total WBCs, neutrophils, lymphocytes, eosinophils basophils increased by 50% in mice with extract compared control However, cells decreased when treated gigas. level cholesterol triglyceride serum was...
The aim of this study was to investigate the molecular characteristics and conduct a comparative genomic analysis Mycobacterium (M.) bovis strain 1595 isolated from native Korean cow.Molecular typing showed that M. has spoligotype SB0140 with mycobacterial interspersed repetitive units-variable number tandem repeats 4-2-5-3-2-7-5-5-4-3-4-3-4-3, representing most common type in Korea.The complete genome sequence determined by single-molecule real-time technology, which 4351712 bp size 65.64%...
Many chemical disinfectants are using to protect the foot and mouth disease (FMD) avian influenza (AI) in Korea since 2000. This study was performed confirm disinfective ability of commercialized investigate sterilizing E-ball as alterative disinfectants. 4 kinds acidulant, 3 aldehyde, 1 kind oxidizer 300 g were used this study. Dilution rate power all 200 times. The aldehydes better than acidulant with Salmonella typhimurium. treated solution guessed due friction deads. In case 2 beads...
Two cases of sudden death without clinical signs in a four-month-old female Hanwoo (Bos taurus coreanae) and sixteen-month-old Holstein taurus) were investigated.Severe pneumonia septicemia found on postmortem examination.Petechial ecchymotic hemorrhages present the subcutaneous tissues neck region.The lungs remained expanded collapsing, mediastinal lymph nodes enlarged.A significant number hemorrhagic bubbles tracheal lumen.On histopathology, alveolar blood vessels moderately congested,...
We conducted diagnostic investigations to analyze the causes of abortions (46 cases, 65.7%), deaths (22 31.4%) and muscular lesions (2 2.9%) occurred after foot mouth disease (FMD) vaccination in livestock farms Korea. Bacterial culture, enzyme-linked immunosorbent assay (ELISA) polymerase chain reaction (PCR) were performed detect causative agents abortion bovine caprine. The results showed that 36 (51.4%) referring as “Identified”, by influence underlying including viral diarrhea (12...
