[Identification of bacterial flora of conjunctival sac in congenital nasolacrimal duct obstruction in children].
OBJECTIVE
The aim of the study was to evaluate the species of the microorganisms and their susceptibility to antibiotics in congenital nasolacrimal duct obstruction in children.


METHODS
The pus secretion after lacrimal sac massage was obtained from 81 children with congenital nasolacrimal duct obstruction. The laboratory diagnostics was performed using typical microbiological procedures. The modification of these procedures was 24-hour pre-incubation in sugar boullion.


RESULTS
The most frequently isolated bacteria were Staphylococcus epidermidis (28%) and Staphylococcus aureus (22%). The isolated staphylococci (only coagulase-negative species MRSE) were resistant to methicillin in 2 cases. Streptococci were obtained in 20% isolations: Streptococcus pneumoniae (14%), Streptococcus viridans (6%). Gram-negative bacilli Pseudomonas aeruginosa and Moraxella spp. and Candida albicans were isolated in a few cases. Negative results of the cultures were obtained in 25% cases.


CONCLUSIONS
The microorganisms typically constituting physiological flora of conjunctival sac may become the pathogens in the complications of congenital nasolacrimal duct obstruction in children.
