目的报道1例由着色真菌monophora引起的皮肤着色芽生菌病。方法取皮损皮屑标本进行真菌直接镜检和培养,同时取活检进行真菌培养和组织病理学检查。对真菌培养阳性菌株进行形态学鉴定、温度试验和放线菌酮耐受试验,PCR扩增测序。结果KOH涂片检查可见较多圆形厚壁棕色硬壳细胞。组织病理学显示为慢性肉芽肿样改变;PAS和银染色可见到圆形厚壁的硬壳细胞。真菌菌落生长缓慢,呈橄榄色到黑色。小培养可见大量棕色菌丝、分支分隔,分生孢子梗主要为喙枝孢型,分生孢子棕色,椭圆形或卵圆形,单细胞。温度试验37℃生长,38℃不生长。0.01%、0.05%和0.1%放线菌酮均能耐受。扩增真菌rDNA的ITS区得到645bp的片段,经序列分析与裴氏着色真菌monophora变种ITS区比对,100%一致。结论据真菌学形态结构特征以及DNA序列分析菌种被鉴定为着色霉monophora。 相似文献

Four patients with deep mycoses were treated with itraconazole. Two patients had chromoblastomycosis, one patient each had aspergillosis and Rhinofacial zygomycosis. These patients were either resistant to or showed poor response to Amphotericin B and/or ketoconazole. After the initial clinical and mycological evaluation, itraconazole was given in a daily dose of 200 mg orally. All patients responded to the drug very well. No adverse effects attributable to itraconazole were detected. 相似文献

Histopathology of chromoblastomycosis 总被引:1,自引:0,他引:1
Summary A study aimed at determining the histopathologic appearance of chromoblastomycotic lesions was undertaken. Biopsies from 26 patients with the disease were examined. It was found that 23 cases (88.46%) exhibited the organized mixed mycotic granuloma — OMMA —, a granuloma modified by the presence polymorphonuclear neutrophils — PMN's. An equal proportion of cases exhibited pseudoepitheliomatous hyperplasia, with the epithelium playing an important role in the transepidermic elimination of the fungus. Healing of the lesions took place by fibrosis which was observed in 21 (80.77%) patients; this type of reaction was more common in the deeper areas of the dermis. 相似文献

Cellular immune response of patients with chromoblastomycosis undergoing antifungal therapy 总被引:1,自引:0,他引:1
One of the most characteristic features of the chromoblastomycosis is its unresponsiveness to treatment. In order to analyzed
whether during therapy could be observed a change of cellular immune response pattern, we evaluated the production of IL-10,
TNF-α and IFN-γ, as well as proliferation of peripheral blood mononuclear cell (PBMC) from patients in different periods of
chemotherapy treatment. Our results showed that after 6 months of treatment cells from patients proliferated to fungal antigens
and produced a significant level of IFN-γ. However, after 1 year of treatment a low proliferation of T cells and production
of IFN-γ accompanied by an increase of IL-10 were observed when compared with 6 months of treatment. 相似文献

Fonsecaea pedrosoi is the principal etiologic agent of chromoblastomycosis, a fungal disease whose pathogenic events are poorly understood. Treatment of the disease presents poor effectiveness and serious side effects. The disease is epidemiologically important in several regions, which has stimulated studies focused on the biology and pathogenic potential of its major causative agent. In this review, we summarize the current knowledge on the biological aspects of F. pedrosoi, including cell differentiation and pathogenic mechanisms during the interaction of fungi with different hosts' elements. 相似文献

A total of 187 Patients with suspected onychomycosis were examined for causative fungal agents between 1996 and 1997. Laboratory
examination confirmed onychomycosis in 115 patients, of which 97 cases were presented with positive microscopic and cultural
examinations, and they were selected for itraconazole pulse therapy. From an etiological point of view, 48.4% of the nail
infections, mainly toenail infections, were caused by dermatophytes, 43.3% were infected with Candida spp, specially infected fingernails, and 8.2% by non-dermatophytic molds. Trichophyton mentagrophytes var. interdigital and T. violaceum were the most prevalent species. Candida albicans and C. parapsilosis were the predominant species of the Genus Candida. Scopolariopsis brevicaulis was the most common non-dermatophyte molds observed. Female affected more frequently than male and in both sexes, those who
were 30–49 years old, more infected. Toenails were affected more frequently than fingernails. In this study, itraconazole
pulse therapy (400 mg daily) gave during the first week of per month for 3 months. The study included 51 patients with toenail
onychomychosis (group 1) and 46 patients with fingernail infections (group 2). Patients were followed up for 9 months after
the last treatment. Clinical response rates were 83% in the group 1, 95% in the group 2 at month 12; the corresponding mycological
cure rates were 71 and 87%, respectively.
