    A comparison has been made of the sensitivities to various antibiotic and non-antibiotic substances of some strains of Pseudomonas aeruginosa and P. stutzeri, the latter including strains isolated from eye and other cosmetic products and from other sources. Whereas P. aeruginosa strains showed a high resistance to cetrimide and to benzalkonium chloride, the P. stutzeri strains were generally more sensitive to these and to chlorhexidine. The P. stutzeri strains were also more sensitive to the various antibiotics tested. The loss of the ability to transfer an R factor by two strains of P. aeruginosa caused no significant change in their drug sensitivity pattern.
