대한수의학회 Journal of Veterinary Science 2013, 제 14권 제 4호 12 457-465 (9 pages)
Bacillus (B.) anthracis, the etiological agent of anthrax, is one of the most genetically monomorphic bacteria species in the world. Due to the very limited genetic diversity of this species, classification of isolates of this bacterium requires methods with high discriminatory power. Single nucleotide repeat (SNR) analysis is a type of variable-number tandem repeat assay that evaluates regions with very high mutation rates. To subtype a collection of 21 isolates that were obtained during a... -

Bacillus (B.) anthracis is the pathogen that causes fatal anthrax. Strain-specific detection of this bacterium using molecular approaches has enhanced our knowledge of microbial population genetics. In the present study, we employed molecular approaches including multiple-locus variable-number tandem repeat analysis (MLVA) and canonical single-nucleotide polymorphism (canSNP) analysis to perform molecular typing of B. anthracis strains isolated in Korea. According to the MLVA, 17 B. anthracis... -

Bacillus anthracis, B. cereus, B. thuringiensis 를 분류하기 위해 rpoB 유전자 배열을 이용한 컴퓨터 분석 작업을 수행하였다. 17개의 B. anthracis, 9개의 B. cereus, 7개의 B. thuringiensis 를 database에서 구하였다. B. anthracis 는 rpoB 유전자의 in silico 제한효소 절단에 의해, B. cereus, B. thuringiensis 2 group과 구별되었다. 그러나 B. cereus와 B. thuringiensis 는 제한효소 절단에 의해 구분되지는 않고, 염기배열과 Blast 탐색의 도움으로 구분이 가능하였다. 본 연구를 통해 3 종류의 Bacillus 종을 동정할 수... -

Bacillus anthracis는 탄저병의 병원체이다. 탄저병의 독소는 Bacillus anthracis가 가진 세가지 독소로 이루어져 있다. protective antigen (PA), lethal factor (LF)그리고 edema factor (EF)로 구성되어 있다. PA는 세포수용체와 결합하여 활성화 과정을 거친 후 LF 흑은 EF를 세포질 안으로 이동시켜 주는 역할을 한다. LF는 금속이온 $(Zn^{2+})$ 의존적 단백질 가수분해 효소로써 탄저병에 감염된 동물들의 치사독소로 작용하게 된다. 따라서 LF에 대한 특성 분석 및 억제재 개발에 관한 연구는 탄저치료제 개발에 매우 중요한... -

대한수의학회 Journal of Veterinary Science 2017, 제 18권 제 4호 3 439-447 (9 pages)
Streptococcus suis is regarded as one of the major pathogens of pigs, and Streptococcus suis type 2 (SS2) is considered a zoonotic bacterium based on its ability to cause meningitis and streptococcal toxic shock-like syndrome in humans. Many bacterial species contain genes encoding serine/threonine protein phosphatases (STPs) responsible for dephosphorylation of their substrates in a single reaction step. This study investigated the role of stp1 in the pathogenesis of SS2. An isogenic stp1... -

Treatment of bovine mastitis caused by Staphylococcus (S.) aureus is becoming very difficult due to the emergence of multidrug-resistant strains. Hence, the search for novel therapeutic alternatives has become of great importance. Consequently, bacteriophages and their endolysins have been identified as potential therapeutic alternatives to antibiotic therapy against S. aureus. In the present study, the gene encoding lysin (LysSA4) in S. aureus phage SA4 was cloned and the nucleotide sequence... -

Anthrax has become endemic throughout the upper Zambezi floodplain located in the Western Province of Zambia over the recent years. To date, no comprehensive study has been carried out to determine whether recurrence of anthrax outbreaks may be linked to differences in precipitation and human activities. Retrospective data for the period 1999 to 2007 showed that a total of 1,216 bovine cases of anthrax were reported. During the same period, 1,790 human anthrax cases and a corresponding case... -

Role of inflammasomes in inflammatory autoimmune rheumatic diseases
Young-SuYi 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 15 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2018, Vol.22 No.1 1 1-15 (15 pages)
Inflammasomes are intracellular multiprotein complexes that coordinate anti-pathogenic host defense during inflammatory responses in myeloid cells, especially macrophages. Inflammasome activation leads to activation of caspase-1, resulting in the induction of pyroptosis and the secretion of pro-inflammatory cytokines including interleukin (IL)-1β and IL-18. Although the inflammatory response is an innate host defense mechanism, chronic inflammation is the main cause of rheumatic diseases, such... -

which is equivalent to 99.9% of the activity of α-tocopherol. In the assessment of anti-bacterial activity, only ethanol extract was found to inhibit the growth of the Bacillus species Bacillus cereus and Bacillus anthracis. These results show that polyphenols of Cynanchi wilfordii Radix have anti-inflammatory, antioxidant, and anti-bacterial properties that can be exploited and further improved for use as a supplementary functional food, in cosmetics, and for pharmaceutical purposes. -

SCS decreased the inducible NO synthase (iNOS) and cyclooxygenase 2 (COX-2) levels, which confirmed the anti- inflam-matory activity of SCS. Further, SCS inhibited vancomycin-resistant enterococci (VRE) and Bacillus anthracis. The minimal inhibitory concentration was 250 μg/ml for VRE and 1,000 μg/ml for B. anthracis. Taken together, these data indicate that SCS has potential anti-inflammatory and anti- superbacterial properties, and thus it can be used as a functional food or pharmaceutical. -

(COX)-2 levels were also decreased, confirming the anti- inflammatory activity. Root polyphenols showed lethal activity against methicillin-resistant Staphylococcus aureus (MRSA), carbapenem-resistant Acinetobacter baumannii (CRAB), and Bacillus anthracis. In contrast, the black raspberry fruit did not demonstrate these properties. These data provide the first demonstration that black raspberry root has potential anti-inflammatory and anti- superbacterial properties that can be exploited as... -

The Hfq protein is a global small RNA chaperone that interacts with regulatory bacterial small RNAs (sRNA) and plays a role in the post-transcriptional regulation of gene expression. The roles of Hfq in the virulence and pathogenicity of several infectious bacteria have been reported. This study was conducted to elucidate the functions of two hfq genes in Burkholderia glumae, a causal agent of rice grain rot. Therefore, mutant strains of the rice-pathogenic B. glumae BGR1, targeting each of the... -

Several Bacillus species were isolated from rice field soils, and 16S rRNA gene sequence analysis showed that Bacillus cereus was the most abundant. A strain named BC1 showed antifungal activity against Rhizoctonia solani. Bacteriophages infecting strain BC1 were isolated from the same soil sample. The isolated phage PK16 had an icosahedral head of 100 ± 5 nm and tail of 200 ± 5 nm, indicating that it belonged to the family Myoviridae. Analysis of the complete linear dsDNA... -

as members of genera Bacillus, Streptomyces, Arthrobacter, Pseudomonas and Mesorhizobium. All tested isolates were capable to degrade both synthetic and natural NAHL produced by Pectobacterium carotovorum subsp. carotovorum (Pcc) strain EMPCC. In quorum quenching experiments selected isolates, especially Mesorhizobium sp., were markedly reduced the pathogenicity of Pcc strain EMPCC in potato tubers and totally suppressed tissue maceration on potato tubers. These led to consider the latter as a... -
