title: Effect of elevated atmospheric pressure on antibiotic susceptibility of Staphylococcus aureus and Streptococcus pyogenes.
abstract: Staphylococcus aureus showed decreased susceptibility to penicillin, vancomycin, sodium cephalothin, and tetracycline, but increased susceptibility to sodium colistimethate, at a pressure of 68 atm in helium or helium-oxygen gas. Susceptibility of Streptococcus pyogenes was unchanged by pressurization.
