A Small RNA Isolation and Sequencing Protocol and Its Application to Assay CRISPR RNA Biogenesis in Bacteria
[Abstract]  Next generation high-throughput sequencing has enabled sensitive and unambiguous analysis of RNA populations in cells. Here, we describe a method for isolation and strand-specific sequencing of small RNA pools from bacteria that can be multiplexed to accommodate multiple biological samples in a single experiment. Small RNAs are isolated by polyacrylamide gel electrophoresis and treated with T4 polynucleotide kinase. This allows for 3’ adapter ligation to CRISPR RNAs, which don’t have ...

Quantification of Neisseria meningitidis Adherence to Human Epithelial Cells by Colony Counting
[Abstract]  To cause an infection, the human specific pathogen Neisseria meningitides must first colonize the nasopharynx. Upon tight interaction with the mucosal epithelium, N. meningitidis may cross the epithelial cellular barrier, reach the bloodstream and cause sepsis and/or meningitis. Since N. meningitidis niche is restricted to humans the availability of relevant animal models to study host-pathogen interactions are limiting. Therefore, most findings that involve N. ...

Live-cell Imaging of Neisseria meningitidis Microcolony Dispersal Induced by Lactate or Other Molecules
[Abstract]  To efficiently colonize the nasopharyngeal epithelium, the human restricted pathogen Neisseria meningitidis follows a multistep adhesion cascade. First, the bacteria adhere to host cells and aggregate into spherical shaped structures called microcolonies. Several hours later, single bacteria start dispersing from the microcolonies and form a monolayer on top of the host cells. Once in proximity to host cells meningococci can adhere tightly to the epithelial surface or become ...
