(2021) GÜRSES, Canbolat; UYAN, Melek; Kuruçay, Ali; PAŞAHAN, Aziz
In our research, the antibacterial properties of tear which protect our eyes from many infections have been investigated by using Bacillus subtilis, Pseudomonas aeruginosa, Staphylococcus haemolyticus and Staphylococcus epidermidis bacteria. In addition, the antibacterial effect of creams in different formulations containing vaseline, also known as petroleum jelly, prepared by mixing olive oil and lemon juice which have been known and used throughout history with tears have been investigated. The antibacterial effect has been investigated measuring the zone of inhibition diameters, also known as the Kirby-Bauer method. It has been determined that all samples showed antibacterial effects except Staphylococcus epidermidis to which only tear was applied. The highest antibacterial activity with tear containing cream (vaseline and olive oil) has been observed for Pseudomonas aeruginosa and Staphylococcus epidermidis bacteria. In addition, tear containing cream (vaseline, olive oil and lemon juice) has shown the highest antibacterial effect against Bacillus subtilis and Staphylococcus haemolyticus bacteria.
