چکیده مقاله:

Introduction: obstruction of lacrimal ducts is called dacryocystitis or lacrimal duct obstruction. Different bacteria, viruses and fungi can cause dacryocystitis, which their identification helps for purposeful treatment. Therefore, the aim of this investigation was to identify prevalent bacteria of lacrimal duct obstruction in infants and adults.Methods & Materials; thirty patients in two age groups of under 2 years and above 15 years with epiphora entered the study. A sample was obtained using sterile swab. Samples sent to microbiology laboratory and cultured on blood agar medium. Afterward, prevalent bacteria including streptococcus pneumonia, staphylococcus aurous and staphylococcus epidermidis were detected using microbial examinations such as catalase or coagulase tests. Finally, data were analyzed using SPSS software for Windows.Results; Regarding the causative pathogen, in infants group, there were 5 positive results for staphylococcus aurous (33.3%), 4 staphylococcus epidermidis (26.7%), 3 streptococcus pneumonia (20%) and 3 negative culture (20%). In adults, there were 4 positive culture for staphylococcus aurous (26.7%), 5 staphylococcus epidermidis (33.3%), 2 streptococcus pneumonia () and 4 negative culture (26.7%). There was no statistically significant difference between the two groups regarding causative pathogen. However, there was no significant association between age and pathogen in the two groups (P=0.378). Left or right infection had not association with the pathogen (P=0.865).Conclusion; the most common isolated pathogen in infants was staphylococcus aurous and in adults staphylococcus epidermidis. Most isolated pathogens were Gram-positive bacteria, therefore should be considered in treatment regimen of dacryocystitis. It is suggested to perform further studies with more sample size.
