| 中文摘要: |
| 马尔尼菲青霉能引起人和鼠类的马尔尼菲青霉病,1956年由Capponi等分离自越南的竹鼠,后由Segretain (1959)正式发表为新种.DiSalvo等(1973)首次报道此菌对人的自然感染,也分离了菌种。Pitt (1980'1979')承认Segretain的菌株为马尔尼菲青霉,但把DiSalvo的菌株(ATCC 24100)由于具明显的黄色菌丝而与岐生青霉金黄色变种(ATCC 10438)合并,成立了樱草黄青霉新种。近年来一些中国的研究者对广西的竹鼠作了大量的调查,证明竹鼠普遍携带此菌,并分离了大量菌株。作者对来自广西的34株分离物(2株来自患者,32株来自银星竹鼠)根据形态和培养特征作了鉴定,并用IMI 68794(来自模式),ATCC 24100和ATCC 10438作了对比。全部34株分离物尽管在菌落外观有明显不同(许多菌株产生黄色具饰菌丝,影响菌落外观)但根据其帚状枝及瓶梗的特征,产生紫红色素以及在370C形成酵母状细胞诸特点,作者认为都是马尔尼菲青霉。ATCC 24100也同样具有马尔尼菲青霉的特征。而ATCC 10438虽然也产生明显的黄色菌丝,但其帚状枝和瓶梗与马尔尼菲青霉不同,不产生紫红色素,在370C不生长,因此不是同一个种。ATCC 24100应保持原来的种名马尔尼菲青霉。 |
| 英文摘要: |
| Thirty-four isolates of fungi (2 from man and 32 from bamboo rats in Guangxi Zhuang Autonomous Region) have been identified on the basis of their morphological and cultural characteristics. IMI 68794 (Penicillium marneffei, ex-type), ATCC 24100 and ATCC 10438 (originally identified as Penicillium marneffei and P. diversum var. aureum respectively but were both reclassified as Penicillium primulinum by Pitt because of their yellow mycelial growth on MEA) were used for comparison. Despite some striking differences in cultural features (many isolates develop yellow encrusted hyphae which influence the colony appearance), all 34 isolates have been identified as Penicillium marneffei Segretain et al. because of the detail of their penicilli, the purplered pigmentation, and the formation of yeast-like cells at 37℃. The morphological characters of ATCC 24100 conform to those of P. marneffei as well. Therefore, ATCC 24100 should still be retained as P. marneffei. ATCC 10438, although it also develops ;ellow encrusted hyphae, possesses a quite different pattern of penicilli. It does not produce a purplered pigment, nor does it grow at 37℃. |
