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:transcription profiles of two groups each containing 5 strains of Disseminated gonorrhoeae (DG) and Undisseminated (superficial) gonorrhoeae (UG) were compared. An additional set of comparisons was done between 4 strains from group one Disseminated gonorrhoeae (DG) and another 4 strains from the same group.
Project description:Hfq is an RNA chaperone, which functions as a pleiotropic regulator for RNA metabolism in bacteria. To characterize the role of Hfq in pathogenicity of Neisseria gonorrhoeae we generated a N. gonorrhoeae hfq mutant, MS11hfq.Transcriptional analysis using a custom-made N. gonorrhoeae microarray revealed that 369 open reading frames were differentially regulated in MS11hfq compared to the wild-type (wt) strain (202 were upregulated, 167 were downregulated).
Project description:Comparison of transcriptional profiling between the 3 Neisseria meningitidis strains [serogroup A (Z2491), Serogroup B (MC58), and Serogroup C (FAM18)] and the 2 Neisseria gonorrhoeae strain (FA1090 and MS11).
