Samples of their cell phones were taken and cultured manually, and sensitivity was determined with antibiogram discs. The instrument was the validated collection card (81%). Stata v.16 software was used for the analysis, using chi-square and Mann Whitney U. Results: 17.2% of the cell phones had growth of Gram-negative bacteria.
