Project description:Microarray comparative genome hybridization (mCGH) data was collected from one Neisseria cinerea, two Neisseria lactamica, two Neisseria gonorrhoeae, and 48 Neisseria meningitidis isolates. For N. meningitidis, these isolates are from diverse clonal complexes, invasive and carriage strains, and all major serogroups. The microarray platform represented N. meningitidis strains MC58, Z2491, and FAM18 and N. gonorrhoeae FA1090.

Project description:Neisseria meningitidis is the leading cause of bacterial meningitis and septicemia worldwide. The novel ST-4821 clonal complex caused several serogroup C meningococcal outbreaks unexpectedly during 2003–2005 in China. We fabricated a whole-genome microarray of Chinese N. meningitidis serogroup C representative isolate 053442 and characterized 27 ST-4821 complex isolates which were isolated from different serogroups using comparative genomic hybridization (CGH) analysis. This paper provides important clues which are helpful to understand the genome composition and genetic background of different serogroups isolates, and possess significant meaning to the study of the newly emerged hyperinvasive lineage. Keywords: comparative genomic hybridization

Project description:Neisseria meningitidis (meningococcus) is usually transmitted via respiratory droplets, whereas its close relative, the gonococcus is sexually transmitted. Invasive meningococcal disease due to isolates of serogroup C increased in Europe and the United States among men who have sex with men (MSM). These isolates were also recovered from cases of urethritis suggesting sexual transmission. Genome sequencing of representative strains revealed that isolates from MSM and urethritis cases belonged to a unique clade within clonal complex11. Proteome analysis showed expression of nitrite reductase by these isolates, enabling anaerobic growth as in gonococci. Invasive isolates from MSM, but not urethritis isolates expressed functional human factor H (hfH) binding protein associated with enhanced survival in transgenic mice expressing hfH, a complement regulatory protein. Our data provide a unique example of meningococcal evolution with adaptation to sexual transmissibility, initially associated with low virulence but with subsequent fHbp-associated invasiveness. Implications for vaccination strategies are discussed.

To further understand the genome diversity of ST-4821 complex isolates, CGH analysis was employed to compare the genomic content of 053442 with those of 27 ST-4821 complex isolates which were isolated from 14 provinces of China during 1977â2005.

Project description:Primary objectives: The primary objective is to investigate circulating tumor DNA (ctDNA) via deep sequencing for mutation detection and by whole genome sequencing for copy number analyses before start (baseline) with regorafenib and at defined time points during administration of regorafenib for treatment efficacy in colorectal cancer patients in terms of overall survival (OS).

Project description:Neisseria meningitidis is a major cause of bacterial meningitis and septicemia worldwide. Seven new serogroup C meningococci were isolated from two provinces of China in January, 2006. Their PorA VR types were P1.20, 9. Multilocus sequence typing results indicated that they all belonged to ST-7. It is a new serogroup C N. meningitidis sequence type clone identified in China. Here we also present the results of a genomic comparison of these isolates with other 15 N. meningitidis serogroup A and B isolates, which belonged to ST-7, based on comparative genomic hybridization analysis. The data described here would be helpful to monitor the spread of this new serogroup C meningococci sequence type clone in China and worldwide. Keywords: comparative genomic hybridization To compare the genome compositions of these menC ST-7 isolates with those of menC ST-4821 isolates, menA ST-7 isolates and menB ST-7 isolates, we performed comparative genomic hybridization (CGH) analysis among 17 N. meningitidis isolates (including two newly identified menC ST-7 isolates) using an updated version of the whole-genome microarray of N. meningitidis serogroup C isolate 053442 .
