Check the micronial Flora of patients using handsfree with others

Ear infection is one of the most important infectious chronic diseases throughout the world, and it is likely that the use of tools such as hands-free causes the transfer of microbial flora and aids the activity of pathogenic microbes. This study compares the ear microbial flora of hands-free users with those who have never used the hands-free in Urmia.
In this study, regardless of the gender, the ears of 24 people (within the range of 20 to 30 years old) who have continuously used hands-free for 3 years and also the ears of 24 people who have never used hands-free were sampled. The samples were cultured in general and specific environment and by using diagnostic tests, the bacteria were identified.
The bacteria isolated from the ears of those who have never used hands-free included: Lactobacillusus, Staphylococcus epidermidis, staphylococcus saprophyticus and non-hemolytic Staphylococcus, and the bacteria isolated from the ears of hands-free users included: Staphylococcus epidermidis, staphylococcus saprophyticus, Staphylococcus aurous, D-non hemolytic streptococcus and viridians streptococcus.
This investigation showed that the use of hands-free causes the transfer of the type and abundance of microbial flora in ears. The result of Chi-square data analysis (P
