Abstract

Pestalotiopsis is an appendage-bearing, well-known plant pathogen, and very few species are associated with human infections. To best of our knowledge, this is first report of Pestalotiopsis spp. isolated from mycetoma patient in India. A 66-year-old male farmer, having a history of twig prick, presented with a swollen foot and multiple discharging sinuses. 10 % KOH mount of tissue and grain showed fragmented fungal elements. White to pale honey-colored colonies with undulated edges and shiny black granules grew on potato dextrose agar. Characteristic fusiform, 5-celled conidia with 2-3 apical appendages seen on LPCB mount. Patient was treated with systemic Itraconazole successfully.

摘要

拟盘多毛孢属是一种带有附属物的著名植物病原体,很少有物种与人类感染有关。据我们所知,这是印度首例从足菌肿患者中分离出拟盘多毛孢属物种的报告。一名66岁的男性农民,有树枝刺伤史,出现足部肿胀和多个排脓窦道。组织和颗粒的10%氢氧化钾涂片显示有真菌碎片。在马铃薯葡萄糖琼脂上生长出边缘起伏、有闪亮黑色颗粒的白色至浅蜂蜜色菌落。在乳酚棉蓝涂片上可见典型的梭形、5细胞分生孢子,有2-3根顶端附属物。患者接受全身性伊曲康唑治疗成功。
