2000年までの6年間に,新潟大学医学部附属病院眼科感染症クリニックで眼感染症患者から669株の菌が検出され,嫌気菌は123症例146株(21.8%)であった。菌種はPfopionibacterium115株(78.8%)でもっとも多く,以下,Peptostreptococcus 8株(5.5%),Prevotella 6株(4.1%),Fusobacterium 3株,Actinomyces 1株などであった。原疾患は,角膜潰瘍24例,急性結膜炎22例,慢性結膜炎18例,角膜炎16例,慢性涙嚢炎16例などであった。検出菌の47.7%は嫌気菌単独で分離された。症例の75.6%に鼻涙管狭窄,副鼻腔炎,糖尿病などの基礎疾患があった。薬剤感受性検査では,全体的にペニシリンG,イミペネム,ミノサイクリンに高感受性を示した。グラム陽性菌はエリスロマイシンとオフロキサシンに,グラム陰性菌はエリスロマイシン,オフロキサシンとバンコマイシンに耐性を示すものがあった。
A total of 669 bacteria were isolated from ocular infections during 6 years through 2000 at our eye infec-tion clinic. Anaerobes accounted for 146 strains (21.8%) from 123 patients. The causative diseases included corneal ulcer 24 cases, acute conjunctivitis 22, chronic conjunctivitis 18, keratitis 16, and chronic dacryocystitis 16. The aero-bic strains comprised Propionibacterium 115, Peptostreptococcus 8, Prevotella 6, Fusobacterium 3, Actinomyces 1, and oth-ers 13. Out of 146 anaerobic strains, 47.7% were isolated alone and the others were detected together with other mi-croorganisms. Out of 123 patients, 75.6% had underlying diseases including stenosis of nasolacrimal duct, sinusitis or diabetes mellitus. Almost all strains were highly sensitive to penicillin G, ampicillin, imipenem and clindamycin. Some gram-positive strains were resistant to erythromycin or Sofoloxacin. Some gram-negative strains were resistant to erythromycin, ofloxacin, or vancomycin.
