ABSTRACT

Objective:To investigate the changes in adaptive phenotypes of Yersinia pestis ( Yp) during successive passages in macrophages. Methods:A Yp strain of 201-MI was induced by 50 successive passages of Yp 201 strain in Raw264.7 cells. Phenotypic characteristics of 201 and 201-MI strains were compared by analyzing their survival rates in macrophages, growth curves, biofilm formation abilities, acid and hydrogen peroxide-stress tolerance, and virulence to mammal cells (Raw264.7 and HeLa cells) and mice. Results:Comparing with 201 strain, 201-MI strain showed various phenotypic changes, including higher survival rate in Raw264.7 cells, faster growth in iron-deficient medium, higher tolerance to acid and hydrogen peroxide, decreased biofilm formation ability, and less damages to Raw264.7 and HeLa cells. More-over, 201-MI strain showed decreased virulence to mice in both subcutaneous and intraperitoneal challenges. Preliminary comparative genomics analysis revealed some indel and nonsense mutations in 201-MI strain, which might account for its phenotype changes.Conclusions:After successive passages in macrophages, Yp showed some phenotypic changes, which might reflect its adaptive evolution under the pressure of macrophages. Detailed multi-omics analysis would be of great help to understand the underlying genetic mechanisms of these changes, and the related Yp-macrophage interaction processes as well.

ABSTRACT

This article describes a novel Multifunctional and Transparent Urinary System Model (MTUSM), which can be applied to anatomy teaching, operational training of clinical skills as well as simulated experiments in vitro. This model covers kidneys, ureters, bladder, prostate, male and female urethra, bracket and pedestal, etc. Based on human anatomy structure and parameters, MTUSM consists of two transparent layers i. e. transparent organic glass external layer, which constraints the internal layer and maintains shape of the model, and transparent silica gel internal layer, which possesses perfect elasticity and deformability. It is obvious that this model is preferable in simulating the structure of human urinary system by applying hierarchical fabrication. Meanwhile, the transparent design, which makes the inner structure, internal operations and experiments visual, facilitates teaching instruction and understanding. With the advantages of simple making, high-findelity, unique structure and multiple functions, this model will have a broad application prospect and great practical value.

ABSTRACT

Objective To investigate the quinolone resistance determinants in ciprofloxacin-resistant Acinetobacter bau-mannii (ABA)clinical isolates.Methods One hundred and fourteen ciprofloxacin-resistant ABA strains were collected from six Chinese hospitals .The quinolone resistance determining region ( QRDR) of 4 target genes ( gyrA, gyrB, parC and parE) was amplified , sequenced and compared with the reference genome of ATCC 17978 to identify possible resistance-related mutations.Nine plasmid-mediated quinolone resistance (PMQR) genes (qnrA, qnrB, qnrC, qnrD, qnrS, qepA, aac(6′)-Ⅰb-cr, oqxA and oqxB) were also amplified, and the amplicons were then sequenced to determine their character-istics.Results Almost all isolates (113/114, 99.1%) harbored a substitution in codon 83 of gyrA gene, leading to a Ser83Leu mutation.Meanwhile,58.8%(67/114) of the isolates possessed dual mutations of GyrA-Ser83Leu and GyrA-Ser80Leu, which were known determinants for ciprofloxacin resistance .There were also multiple non-synonymous substitu-tions in gyrB, leading to Arg393Ser, Arg393Cys, Thr401Ala, Pro406Ser, Val430Phe, Cys440Ser and Gly480Arg muta-tions with prevalence rates of 95.6%, 0.9%, 96.5%, 96.5%, 100%, 96.5%and 96.5%,respectively.For parE, all the seven mutations were synonymous and found in more than 96%of the tested isolates.For PMQR genes, although 83.3%(95/114) of the isolates were positive for aac(6′)-Ⅰb, nocrmutations were identified.None of the other eight PMDR genes were found in our strain collection .Conclusion Although multiple mutations are identified in gyrB and parE, these mutations might be the characteristic SNP markers for specific clones , unlikely linked to quinolone resistance .No PMQR is found in the tested isolates.Mutations in chromosomal QRDR (GyrA-Ser83Leu and ParC-Ser80Leu) are the main determi-nants of ciprofloxacin resistance in our ABA collection .

ABSTRACT

A gas chromatographic analysis method was employed to determine the cellular fatty acids (CFAs)profiles of the spores of some aerobic endospore4orming bacilli. Purified spore cultures of 51 experimentas strains were processed to acquire whole cell fatty acids methyl esters for the subsequent gas chromatographic analysis,and the corresponding vegetative cells were set as control. The reproducibility study of spore fatty acids revealed that,the fatty acids components of spores were stable enough for research purpose,provided under standardized experimentas procedure. The dendrograms obtained by cluster analysis provided some meaningful taxonomic information of the experimental strains. The fatty acids analysis of spores seemed to be a promising supplementary tool for the chemotaxonomic research of aerobic endospore-forming bacilli.

ABSTRACT

Objective:To obtain oligonucleotide aptamers which can specifically bind to Bacillus anthracis spores by in vitro selection protocol-SELEX (system evolution of ligands by exponential enrichment).Methods:An in vitro synthesized 78 mer random DNA library (≤1014-15types of different DNAs ) was subjected to 15 rounds of selection using SELEX method against spores of B.anthracis vaccine strain A.16R. Binding of the aptamers to spores was visualized by biotin-streptavidin-horseradish peroxidase system.Results:PCR amplification band pattern of the first round selection was different from that of the ninth round. The binding assay demonstrated that D absorbance at 450 nm of the fifteenth round pool increased 9 times as compared with that of the first round , and the D absorbance increased with the increment of aptamers′ quantity binding to spores. Conclusions: A set of aptamers with considerable binding affinity to B.anthracis spores were successfully selected from the initial random DNA pool.

ABSTRACT

Objective To better understand the pathogenicity and evolution of Yersinia pestis, we carried out the whole genome sequencing of human-avirulent Yersinia pestis strain 91001, which was isolated from a species of rodent-Microtus brandti. Methods We utilized “whole genome shotgun” approach to get the genome sequence of 91001. Based on the finished and annotated genome sequence of 91001, as well as the previously published genome sequences of CO92 and KIM, we performed detailed comparative genomics analysis on their chromosomes and plasmids. Results The genome of 91001 consisted of one chromosome and four plasmids (pPCP1, pCD1, pMT1 and pCRY). The pPCP1 plasmid of 9 609bp was almost identical with its counterparts from reference strains, which possessed 10 CDS. Plasmid pCD1 was found to be a plasmid of the type III secretory apparatus, and its length was 70 159bp. Although its CDS are quite similar to those of the reference plasmids, there were obvious rearrangements which produced certain differences in structure among them. Another plasmid was pMT1, a 106 642bp plasmid, which showed slightly different architecture compared with the reference ones. There was no mutation in virulent-related genes of pMT1 and pMT1 of 91001, which seemed to have retained more fragments of an ancestor plasmid. pCRY was a novel plasmid discovered in this work. It was 21 742bp long and harbored a group of gene encoding type IV secretory system. pCRY seemed to be able to replicate. The length of chromosome of 91001 was 4 595 065bp, and among its 4 037 predicted CDS (coding sequences), 141 were possibly pseudogenes. There were many IS in the chromosome. Due to the rearrangments mediated by IS, the structure of 91001 chromosome showed significant differences compared with CO92 and KIM. According to the results of comparative genomics analysis, we deduced the genetic mechanisms of nitrate reduction, glycerol fermentation, arabinose and milibiose utilization in 91001. Conclusion According to the analysis of plasmids structure, pseudogenes distribution, nitrate reduction negative mechanism, gene comparison and chromosome architecture, we conclude that 91001 and other strains isolated from Microtus brandti and Microtus fuscus evolved from ancestor Y. pestis and then developed into a different lineage. The deletion of large genome fragments from 91001 chromosome and pseuogenes might contribute to its unqiue pathogenicity and host-specificity.
