Previously it has been demonstrated that Staphylococcus aureus is sensitive towards Pseudomonas secreted exotoxins, which preferentially target the electron transport chain in staphylococci. Here it is shown that a subpopulation of S. aureus survives these respiratory toxins of P. aeruginosa by selection of small colony variant (SCV) phenotype. Purified pyocyanin alone causes the same effect. A hemB mutant of S. aureus survives co-cultivation with P. aeruginosa without decrease in CFU
