A Preliminary Study of Bacterial Contamination from Elevators

Dr. Khatib Sayeed Ismail

Abstract :

The present study aims to understand the level of bacterial contamination of elevator buttons at the Faculty of Science building, Jazan University, Jazan, Kingdom of Saudi Arabia. A total of 20 samples (n = 20) were collected using sterile cotton swabs from buttons of 4 different elevators (5 samples each from 4 elevators). Samples were isolated on Nutrient agar and MacConkeys agar. The agars were incubated at 37°C for 24 hours and observed for growth. The colonies were subjected to Grams’ staining and observed under a microscope. All the samples (100%) showed bacterial contamination. Staphylococcus species (20 samples, 100%), Gram negative bacilli (9 samples, 45%), Streptococci spp. (6 samples, 30%) and Gram positive bacilli (3 samples, 15%) were isolated. Staphylococcus species was most dominant followed by Gram negative bacilli, Streptococci and Gram positive bacilli. Staphylococcus aureus was isolated from 75% samples. Three samples (15%) were found contaminated by single type of bacteria while 85% samples were contaminated by more than 1 type of bacteria. The presence of bacterial contaminants on elevators indicated the probable tool for spread of pathogenic microorganisms
