* Our project involves manipulating the CRISPR pathway as a gene regulation tool. The CRISPR system is naturally present in many prokaryotes and nearly all archea. Introducing a CRISPR locus into a non-CRISPR organism has the potential to increase its resistance to phages. This is unlikely to have a significant effect on pathogenicity, especially in experiments in which the genes involved in incorporation of new spacers (CAS1 and CAS2) are removed. All strains used in the lab (E. coli as well as B. halodurans) are common lab strains. Appropriate biosafety level 2 precautions are taken.

General Lab safety: All members of our team were required to attend biosafety training according to Arizona State policy before working in the lab. The lab space is classified as biosafety level one. As such, rules concerning proper physical attire and use of protective barriers like gloves are combined with aseptic techniques to ensure cross-contamination between lab organisms and researchers does not occur. All biological trash is autoclaved before disposal.

Safety issues concerning CRISPR: Our project involves manipulating the CRISPR pathway as a gene regulation tool. The CRISPR system is naturally present in many prokaryotes and nearly all archea. Introducing a CRISPR locus into bacteria lacking CRISPR has the potential to increase resistance to phage attack and plasmid uptake. This is unlikely to have a significant effect on pathogenicity, especially when the spacers are designed to target relatively benign genes products such as GFP, as in our proof of concept. Currently our constructs omit two genes (CAS1 and CAS2) implicated in the incorporation of new spacers into CRISPR arrays such that we minimize the possibility of unwanted targeting that could potentially increase pathogenicity (although there is no evidence to suggest that this would even be a favorable event).
