Project description:Using comparative genomic hybridization we examined the genome content of 30 isolates of E. coli and Shigella to determine the relative location of E. coli isolates from the human neobladder
Project description:We compared the transcriptional profiles of 12 E. coli O157:H7 isolates grown to stationary phase in LB broth. These isolates possess the same two enzyme PFGE profile and are related temporally or geographically to the above outbreak. These E. coli O157:H7 isolates included three clinical isolates, five isolates from separate bags of spinach, and single isolates from pasture soil, river water, cow feces, and a feral pig.
Project description:E. coli isolates from different CF patients demonstrate increased growth rate when grown with glycerol, a major component of fecal fat, as the sole carbon source compared to E. coli from healthy controls. CF and control E. coli isolates have differential gene expression when grown in minimal media with glycerol as the sole carbon source. While CF isolates display a growth promoting transcriptional profile, control isolates engage stress and stationary phase programs, which likely results in slower growth rates.
Project description:Comparative genomic hybridization between Escherichia coli strains to determine core and pan genome content of clinical and environmental isolates
Project description:Each sample includes 5 pooled whole-brains from adult worker honey bees collected across two behavioral groups: soldiers and foragers. We used the Chromium Single Cell 3' Reagent Kits with the Chromium Controller (10x Genomics) and performed sequencing on the Illumina NovaSeq 6000.

Twelve condition experiment, 12 E. coli O157:H7 isolates. Two biological replicates for isolates RM6067, RM6069, RM6101, RM6102, RM6103, RM6149, RM6655, RM6658, RM9992, RM9997, RM9998 and RM10002 independently grown to stationary phase in LB at 37°C and harvested. One replicate per array. A type 2 gene expression experimental design was used, with fluorescently labeled genomic DNA as a reference channel in each experiment as described by Lucchini, S., et al. 2005. Infect Immun 73:88-102.
Project description:Using comparative genomic hybridization we examined the genome content of 30 isolates of E. coli and Shigella to determine the relative location of E. coli isolates from the human neobladder Isolates were included in the study that represent the prototype strains of multiple pathovars. No replicates were included in the final comparisons
