Microorganismos presentes en los teléfonos celulares de estudiantes y docentes durante la consulta odontológica en la Universidad Santo Tomás

Abstract

The presence of pathogenic microorganisms such as Staphylococcus aureus and Escherichia coli in the different clinical spaces, together with the constant use of the cellular device can cause cross-contamination, generating pathologies in patients or in the staff present in clinical care. Target. Determine the presence of Staphylococcus aureus and Escherichia coli in cell phones of students and faculty at st. Thomas University dental clinics, Floridablanca during clinical care. Methodology. A descriptive cross-sectional study was conducted in dental students and teachers. A random sample of 100 participants was selected, who with a sterile swab moistened in saline were taken from the sample which was taken to the laboratory in nutrient broth. There a sterilization process was carried out of the implements necessary for planting, using the autoclave and the UV filter booth. Planting was carried out in MacConkey Agar for Escherichia coli and Baird- Parker Agar for Staphylococcus aureus, performing an incubation for 48 hours at 37oC to analyze its growth and identification by Gram staining. Results. A median 8 UFC and 2 UFC Escherichia coli was shown for the Staphylococcus aureus. On the other hand, the presence of microorganisms of 47% was found from microbiological isolation, with 46% Staphylococcus aureus and 9% Escherichia coli. Conclusion. It can be noted that the presence of microorganisms in cellular devices is high, specifically Staphylococcus aureus (46%) and Escherichia coli (9%) . According to the selected variables, the clinic in dental care showed statistical significance (value of p.039), interpreting that according to the advance in the academic level (semester) increases the interest of disinfection or the decrease in use of the mobile phone during clinical care.
