Enterococcus spp. are pathogens that cause environmental mastitis and difficult to eliminate owing their resistance antibiotics. To compare the virulence characteristics of isolates from bovine milk (BMM) normal raw (NRM), we isolated 39 dairy farms in South Korea 2015−2020. A total 122 were identified, with faecalis (73.8%) accounting for majority, followed by faecium (26.2%). E. BMM harbored gelE, asa1, esp, cylA genes a prevalence 85.7, 71.4, 54.3, 30.0%, respectively. These significantly...

ABSTRACT Methicillin-resistant Staphylococcus aureus (MRSA) is a drug-resistant pathogen causing subclinical and clinical bovine mastitis. This study examined the molecular properties, biofilm formation, virulence genes, antimicrobial susceptibility of MRSA isolates from mastitis-infected dairy cow milk in South Korea. Whole-genome sequencing an ST22-SCC mec IV strain positive for Panton–Valentine leukocidin (PVL) toxic shock syndrome toxin-1 (TSST-1) was also performed. Of 488 S . isolates,...
Staphylococcus hyicus causes porcine exudative epidermitis, predominantly affecting suckling and weaned piglets. This bacterium produces various exfoliative toxins (ExhA, ExhB, ExhC, ExhD, SHETA, SHETB), which are responsible for the clinical manifestations of epidermitis. However, treatment failure is common due to frequent antimicrobial resistance in strains. Therefore, this study aimed identify genes encoding assess profiles S. hyicus. A total 17 isolates were collected from piglets with...
The introduction of bacteria into slaughterhouses can lead to microbial contamination in carcasses during slaughter, and the initial level is important because it directly affects spoilage shelf life. This study was conducted investigate microbiological quality, prevalence foodborne pathogens 200 from 20 pig across Korea.

본 연구의 목적은 고등학생을 대상으로 진로관련 부모지지가 학교생활 만족도에 이르는 과정에서 진로결정 자기효능감과 자율성의 구조적 관계를 탐색하는 것이다. 또한 이들 변인들 간의 관계가 성별에 따라 어떠한 차이가 있는지 확인하고자 하였다. 이를 위해 J도 소재의 고등학생 563명의 설문응답 결과를 분석하고, 부모지지와 만족도의 자율성이 매개하는 것으로 가설모형을 설정하여, 관계에 방향을 설정한 2가지 경쟁모형과 비교하였다. 그 결과 미치는 직접적인 영향력이 확인되었고, 자율성을 거쳐 간접 경로와 자기효능감을 자율성에 영향을 주어 이르게 되는 간접경로의 통계적 유의성이 확인되었다. 그리고 남학생의 경우 유의하지 않았으며, 부모지지에서 만족도, 자기효능감, 자율성으로 가는 경로계수가 남학생보다 여학생이 더 높은 나타나 따른 관계 및 경로계수의 차이를 확인하였다. 이러한 결과의 의의 제한점이 논의되었다.
본 연구는 장류시장을 개척할 수 있는 속성장을 발굴하여 장류 소비확대와 장류산업 발전에 기여하고자 메밀을 이용한 제조하였고, 그 실용화와 대량화를 위하여 메밀의 배합비, 염도 및 수분함량을 결정하고자 하였으며, 제조 후 다양한 품질특성을 조사하였다. 결과, 4 종류 속성장의 초기 수분함량은 52~64% 수준으로 다양하였고, 숙성기간이 길어질수록 수분함량이 조금씩 감소하여 숙성 70일째는 53~58%를 나타냄으로써 시료 상의 아주 큰 차이는 보이지 않았다. 메밀 pH는 70일째 5.1~5.6의 값을 나타내었고, 총산의 경우 0.6~0.8%의 범위로 염 함량이 낮은 된장일수록 높은 산도를 보였다. 총 미생물 균수는 70일째까지 전반적으로 1~3 log cycle 정도 균수가 감소하였다. 발효기간엔 모든 시료에서 44~89 mg% 분포로 아미노태 질소의 함량을 보이다 숙성이 진행될수록 꾸준히 증가하여 152~213 나타내었다. 발효 70일 된 관능검사 전체적인 기호도는 처리 간에...
