Abstract
Alfredo J. Guerra works in the field of molecular parasitology and structural biology. In this mSphere of Influence article, he reflects on how "Efficient Gene Disruption in Diverse Strains of Toxoplasma gondii Using CRISPR/CAS9" by Bang Shen et al. (mBio 5:e01114-14, 2014, https://doi.org/10.1128/mBio.01114-14) and "Efficient Genome Engineering of Toxoplasma gondii using CRISPR/CAS9" by Saima M. Sidik et al. (PLoS One 9:e100450, 2014, https://doi.org/10.1371/journal.pone.0100450) made an impact on him by successfully implementing strategies to genetically manipulate T. gondii using CRISPR/CAS9 gene editing technology.
