Benyamin Karimi1, Mohammad Ali Malekan1, Ahmad Reza Shamshiri2, Masoomeh Mohkam1, Mostafa Sharifian1, Saeed Maham1On the base of relation between oropharyngeal colonization of bacterial pathogens and etiology of invasive and noninvasive pediatric diseases, we evaluated their prevalence and relationship between them.
The colonized bacteria in oropharynx of 296 children between 2-6 years old from 7 day care centers of Tehran were isolated and determined by specific diagnostic tests.
Prevalence rates of bacterial colonization include Streptococcus pneumoniae (32.4 %), Haemophilus influenza (23.9%), Moraxella catarrhalis (13.5%), Neisseria meningitides (12.1%) and pseudomonas aeruginosa (2.7%). Our study showed the reverse relationship between colonization rate of Streptococcus Pneumoniae and Haemophilus influenza and between Neisseria meningitidis and Haemophilus influenzue.
Determination of colonized bacteria in oropharynx of healthy children and relationship between them can be helpful to find the ways to interfere with their colonization and prevention of diseases due to them.
