title: Carbon dioxide laser irradiation of bacterial targets in vitro.
abstract: Agar targets seeded with Escherichia coli and Staphylococcus aureus in roll tubes simulating the vaginal vault were irradiated with a CO2 laser at various power densities and durations. Viable bacteria were detected in the plume emissions in all instances. Staphylococcus aureus was found to be more resistant to the thermal effects of lasing than E. coli. This suggests that CO2 irradiation of cervical lesions could disseminate viable particles which may be a hazard for patients and operators.
