ABSTRACT
@#

AIM:

To explore the pathogenic bacteria and drug resistance of acute dacryocystitis, and to provide a guide for rational clinical medication.<p>

METHODS:

Lacrimal sac pus samples from 80 acute dacryocystitis cases were collected for bacterial culture and drug sensitivity test in Hebei Provincial Eye Hospital from January 2014 to October 2019. The change of detection rate of pathogenic bacteria in different years, the species of pathogenic bacteria of acute dacryocystitis, the main pathogenic bacteria, drug sensitivity and drug resistance of acute dacryocystitis, and the average detection rate of pathogenic bacteria in acute dacryocystitis were analyze.<p>

RESULTS:

Totally 56 samples were positive for pathogenic bacteria, including 55 cases of bacteria and 1 case of fungi. The average detection rate was 70%. The detection rate of pathogenic bacteria strains was gradually decreasing year by year, and there were various types of pathogenic bacteria strains detected from samples. In addition, Gram-positive cocci was the main pathogenic bacteria of acute dacryocystitis, accounting for 68%(38 cases), of which, staphylococcus aureus accounted for 38%(21 cases). What's more, most Gram-positive cocci were sensitive to rifampin, levofloxacin, and chloramphenicol, and Gram-negative bacilli were more sensitive to tobramycin, levofloxacin, ciprofloxacin, and gentamicin. Fifty-five cases of bacterial samples were obviously resistant to the first and second generation cephalosporins.<p>

CONCLUSION:

Gram-positive cocci constitute the main pathogenic bacteria of acute dacryocystitis, and levofloxacin can be used as the first choice of topical antibiotics for the treatment of acute dacryocystitis.
