In the case reported, herpes virus I after having caused relapsing keratitis in an eye promoted the formation of a severe corneal ulcer caused by Scopulariopsis brevicaulis, a saprophytic mycete found in soil, which only once has been described as the cause of keratitis in man. Scopulariopsis was identified microscopically after culturing the conjunctival secretion on Sabouraud dextrose agar medium, while DNA probe tests confirmed the absence of herpes virus I. Topical and oral administration of miconazole and scraping of the corneal infiltrate dispersed the infection. Subsequently local steroids were given to reduce the neovascularization, and a therapeutic contact lens was applied because of intercurrent corneal thinning. Three months after beginning antifungal therapy, the visual acuity had increased from 1/120 to 1/10. The case described confirms that S. brevicaulis can cause opportunist infections in a cornea previously damaged by a different agent.
在所报道的病例中,Ⅰ型疱疹病毒在一只眼睛引起复发性角膜炎后,促使由短帚霉引起的严重角膜溃疡形成,短帚霉是一种在土壤中发现的腐生真菌,仅曾有一次被描述为人类角膜炎的病因。在沙氏葡萄糖琼脂培养基上培养结膜分泌物后,通过显微镜鉴定出短帚霉,而DNA探针检测证实不存在Ⅰ型疱疹病毒。局部和口服咪康唑以及刮除角膜浸润物使感染消散。随后给予局部类固醇以减少新生血管形成,并因并发角膜变薄而佩戴治疗性隐形眼镜。开始抗真菌治疗三个月后,视力从1/120提高到1/10。所描述的病例证实,短帚霉可在先前被另一种病原体损伤的角膜中引起机会性感染。
