 Abstract

Nitric oxide (NO) is a reactive nitrogen species (RNS) that
plays a vital role in regulating inflammatory processes. Under
abnormal conditions, excessive NO levels can promote the
oxidation of cellular components, which may cause or exacerbate
diseases such as hypertension, cardiovascular dysfunction,
and inflammatory bowel disease (IBD). Previous
studies have shown that reducing NO levels in the lumen can
attenuate the clinical symptoms of IBD. Thus, we aimed to
identify bacteria that can reduce RNS and that can be used
as valuable probiotics. In this study, we isolated bacteria resistant
to nitrite stress from human feces and used 16S and
whole-genome sequencing to identify them as Lactiplantibacillus
plantarum LP7 (LP7). The ability to survive at high
nitrite levels and to decrease them was greater in the LP7 strain
than in the reference strain L. plantarum ATCC14917 (ATCC-
14917). To characterize the LP7 genome in more detail, we
performed a comparative genome analysis. However, the unique
genes that directly confer the ability to withstand nitrite
stress were not present in the LP7 genome. Furthermore, we
performed transcriptomic analysis of LP7 and ATCC14917
cells treated with nitrite. We found that the expression levels
of genes involved in the cell division process were induced in
LP7, which showed a more regular rod-shape than ATCC-
14917. This could explain why LP7 can survive better than
ATCC14917 under nitrite stress. Based on its ability to survive
better in nitrite stress and decrease nitrite concentration,
we suggest that LP7 could be a valuable probiotic strain.

An obligate anaerobic, Gram-reaction-negative, non-sporeforming,
non-motile, rod shaped bacterium designated YMC
B3181T was isolated from the blood of a patient with peritonitis.
Strain B3181T grew at 20 to 40°C with optimum growth
at 37°C. 16S rRNA gene sequence similarity showed strain
B3181T belongs to the genus Parabacteroides and is closely
related to Parabacteroides faecis 157T (97.3%), Parabacteroides
gordonii MS-1T (96.6%), and Parabacteroides goldsteinii
DSM 19448T (95.7%). The G + C content of the genomic DNA
was 42.3 mol%. The major cellular fatty acids were anteiso-
C15:0 and iso-C17:0 3-OH, and the predominant respiratory
quinones were MK-9 and MK-10 menaquinones. Genomic
and chemotaxonomic data supported affiliation of B3181T
with the genus Parabacteroides. Strain B3181T was phylogenetically
and phenotypically different from recognized species
of the genus Parabacteroides. Accordingly, this isolate
belongs to a novel species for which the name Parabacteroides
chongii sp. nov. (type strain YMC B3181T = LMG
30065T = KACC 19034T) is proposed.

The flanking genetic structure of qnrA1 in Korean Enterobacter
cloacae was identical to that of the Chinese Escherichia
coli strain, the first qnrA1-carrying strain reported in Asia.
Analysis of restriction enzyme sites and Southern blot
hybridization results showed that qnrA1 was transferred
between E. cloacae and E. coli via Inc HI2 type plasmid.

This study was performed to characterize the chromosomal metallo-β-lactamases (MBLs) of Elizabethkingia meningoseptica isolated from Korea and to propose a clustering method of BlaB and GOB MBLs based on their amino acid similarities. Chromosomal MBL genes were amplified by PCR from 31 clinical isolates of E.
meningoseptica. These PCR products were then cloned into a vector and electrotransformed into E. coli DH5α. Nucleotide sequencing was performed by the dideoxy chain termination method using PCR products or cloned DNA fragments. Antimicrobial susceptibilities were determined by the agar dilution method. PCR
experiments showed that all 31 E. meningoseptica isolates contained both the blaB and the blaGOB genes. DNA sequence analysis revealed that E. meningoseptica isolates possessed seven types of blaB gene, including five novel variants (blaB-9 to blaB-13) and 11 types of blaGOB gene, including 10 novel variants (blaGOB-8 to blaGOB-17). The most common combination of MBL was BlaB-12 plus GOB-17 (n=19). Minimum inhibitory concentrations of imipenem and meropenem for the electrotransformants harboring novel BlaB and GOB MBLs were two- or four-fold higher than those for the recipient E. coli DH5α. BlaB and GOB MBLs were
grouped in three and six clusters including fifteen novel variants, respectively, based on amino acid similarities.

Vancomycin-resistant Enterococcus faecium (VREFM) is becoming a threatening pathogen. We identified a gene called DD1.5K by differential display-PCR, which was preferentially expressed in the bloodstream isolates of VREFM. Due to its amino acid similarity to transfer complex protein, trsE, and tissue-specific expression, this gene may be involved in virulence of VREFM.
