To define the microbiological features of dacryocystitis in childhood.
Patients with dacryocystitis secondary to CNLDO between 2017 and 2019 in Izmir, Turkey were included in the study. Inclusion criteria of the study were: mucopurulent secretion, being under 4 years old and not having received prior antibiotic treatment. Samples from secretion were cultivated in sheep blood agar, eosin methylene blue, and chocolate agar. Reproduction was checked intermittently. Clinically significant growths were reported.
Seventy patients with dacryocystitis secondary to CNLDO were included in the study. Sixty percent of patients were female (n = 42) and 40% (n = 28) percent of patients were male. The average age of participants was 2.09 ± 0.68 (1-3) years old. Positive bacterial proliferation results were noted in 20 patients (28.6%). Eighty percent (n = 16) of culture-positive bacterias were gram-negative bacterias and 20% (4) were gram-positive bacterias. Twenty percent of culture-positive bacterias were aerobic and 80% were facultative bacterias. The most common bacteria seen in culture specimen was Haemophilus 40% (Haemophilus haemolyticus [20%] and Haemophilus influenzae [20%]).
Gram-negative organisms especially Haemophilus were most prevalent. These findings could be helpful for antibiotic selection.
明确儿童泪囊炎的微生物学特征。
纳入2017年至2019年在土耳其伊兹密尔因先天性鼻泪管阻塞继发泪囊炎的患者。本研究的纳入标准为：有黏液脓性分泌物、年龄在4岁以下且未接受过抗生素治疗。分泌物样本在绵羊血琼脂、伊红美蓝琼脂和巧克力琼脂中培养。间歇性检查细菌繁殖情况。报告具有临床意义的细菌生长情况。
70例因先天性鼻泪管阻塞继发泪囊炎的患者纳入本研究。60%的患者为女性（n = 42），40%（n = 28）的患者为男性。参与者的平均年龄为2.09±0.68（1 - 3）岁。20例患者（28.6%）细菌增殖结果为阳性。培养阳性细菌中80%（n = 16）为革兰氏阴性菌，20%（4例）为革兰氏阳性菌。培养阳性细菌中20%为需氧菌，80%为兼性菌。培养标本中最常见的细菌是嗜血杆菌，占40%（溶血嗜血杆菌[20%]和流感嗜血杆菌[20%]）。
革兰氏阴性菌尤其是嗜血杆菌最为常见。这些发现可能有助于抗生素的选择。
