A novel bacterial strain, designated PFS-5T, was isolated from the soil environment with feces of a live poultry farm located in Cheonan, Republic of Korea. Strain PFS-5T was Gram-staining-positive, motile, strictly aerobic bacterium, rod-shaped, and endospore-forming. The strain contained meso-diaminopimelic acid in their peptidoglycan and MK-7 menaquinone. The major fatty acids were anteiso-C15:0 (44.2%), C16:0 (22.2%), and iso-C15:0 (16.7%). The DNA G+C content was 40.1 mol%. Comparative 16S rRNA gene sequence analysis identified strain PFS-5T in the genus Bacillus, exhibiting the highest level of sequence similarity with type strain of B. herbersteinensis D-1,5aT (96.9%), B. humi LMG 22167T (96.7%), B. alkalitelluris BA288T (96.1%), B. litoralis SW-211T (96.0%), and B. luteolus YIM93174T (95.5%). The major polar lipids of PFS-5T were diphosphatidylglycerol and phosphatidylglycerol. On the basis of result from poly-phasic data, strain PFS-5T represents a novel species, for which the name Bacillus cheonanensis sp. nov. is proposed (Type strain PFS-5T= KACC 17469T= JCM19333T).

Abstract PDF

In the current study, we generated a pool of Salmonella typhimurium mutants using the Tn10d-cam minitransposon. This pool of mutants was administered to BALB/c mice through the oral route, and bacteria were recovered from the spleen 3 days post-infection. After three rounds of serial passage, we observed enrichment of two insertion mutants, a yddG insertion and an amyA insertion. These two genes have been implicated in growth on plant products (amyA) and survival in the presence of paraquat (yddG), both of which are natural environments for Salmonella. Thus, while in vivo expression technology has identified S. typhimurium genes that are absolutely necessary for animal infection, other genes involved in vegetative growth also appear to play role in the establishment of pathogenesis.

Abstract PDF

Salmonella enterica is highly diverse in terms of genome structure, which is at least partly due to the horizontal transfer of genetic elements from various sources. In this study, we examined the expression profiles of such genes in Salmonella Pathogenicity Islands (SPIs) and the cob/pdu locus, horizontally acquired large DNA segments, during growth under standard growth conditions. Transcripts from exponentially growing and early stationary phase Salmonellae were compared using various methods including cDNA microarray analysis. Nearly all genes encoded by SPIs and the cob/pdu locus were induced at the onset of the stationary phase in a stringent molecule ppGpp-dependent but stationary phase σ, σ38-independent manner. Although, it has been suggested that ppGpp acts in concert with DksA, we found the stationary phase induction of those SPI genes was not DksA dependent. It is suggested that ppGpp stimulates the expression of these stress-inducible genes encoded by horizontally acquired DNA, by itself or in concert with DksA.

Abstract PDF: Epilepsy constitutes a significant public health problem, and even the newest drugs and neurosurgical techniques have proven unable to cure the disease. In order to select a group of isolates which could generate an active compound with neuroprotective or antiepileptic properties, we isolated 517 actinomycete strains from soil samples taken from Jeju Island, in South Korea. We then screened these strains for possible anti-apoptotic effects against serum deprivation-induced hippocampal cell death, using the 3-(4, 5-dimethylthiazol-2-yl)2,5-diphenyl-tetrazolium bromide (MTT) assay as an in vitro test. The excitotoxic glutamate analog, kainic acid (KA), was used to induce seizures in experimental mice in our in vivo tests. As a result of this testing, we located one strain which exhibited profound neuroprotective activity. This strain was identified as a Streptomyces species, and exhibited the rifampin-resistant genotype, Asn(AAC)^442, according to the results of 16S rRNA and rpoB gene analyses
