ABSTRACT

Staphylococcus aureus is the most common species implicated in infectious diseases causing morbidity and mortality worldwide. It has the hla, hlb, hld, hlg, hlg-v genes encoding for hemolysins. Hemolysins are recognized as a potential virulence factor that attacks the membrane and causes platelet destruction and necrosis. They have the ability to survive for long periods on inert surfaces such as cell phone screens. Observational descriptive cross-sectional study. Sixteen strains of Staphylococcus aureus were isolated in a previous study from 92 samples of cell phone screens of dental students; the polymerase chain reaction technique was used to detect genes coding for hemolysins. The hla gene was detected in 75% (12/16) of Staphylococcus aureus strains, hlb in 25% (4/16), hld 75% (12/16), hlg 75% (12/16), hlg-v 13 % (2/16). This study evidences the high percentage of virulent strains that possess genes encoding for hemolysins in cell phone screens, which may contribute to the dissemination of this pathogen. It is imperative to implement measures for the disinfection of cell phones.
