This allows for consecutive rounds of genome editing. Using this system, we engineered a strain with three major virulence factors deleted. The approaches developed here could potentially be adapted for use with other Gram-positive bacteria.IMPORTANCEStreptococcus pneumoniae (the pneumococcus) is an important opportunistic human pathogen killing more than 1 million people each year. Having the availability of a system capable of easy genome editing would significantly facilitate drug discovery and efforts to identify new vaccine cand
