新型隐球菌脑膜炎病人的脑脊液的印第安蓝染色，可见病原体中央的细胞核周围呈现清晰亮区的孢囊。

This is an India ink preparation of cerebrospinal fluid in a patient with Cryptococcus neoformans meningitis. Note the clear zone of the capsule around the central nucleus of the organisms.

可见带有假菌丝的芽殖细胞是假丝酵母感染的特征。

Budding cells with pseudohyphae seen here are characteristic for Candida infection.

PAS染色，假丝酵母的出芽细胞和假菌丝(短细丝不是真正的菌丝)被染为鲜红色。

With a PAS stain, the budding cells and pseudohyphae (short filaments that are not true hyphae) of Candida stain bright red.

假丝酵母GMS染色。

Here is a GMS stain of Candida.

免疫缺陷的宿主中口腔念珠菌病很普通,例如 HIV 感染。见毛状舌胎，并有浅棕色渗出物，即毛状白斑舌。

Oral candidiasis is common in immunocompromised hosts, such as those with HIV infection. There is a hairy coating of the tongue seen here mixed with a pale tan exudate.

PAS染色显示舌表面上假丝酵母的芽殖细胞和假菌丝。

A PAS stain reveals the budding cells and pseudohyphae of Candida on the surface of the tongue.

肺霉菌脓肿标本，可见脓肿的黄褐色物质。 由于它由霉菌菌丝组成，非常牢固。这归因于曲霉属菌。曲霉属菌通常在已形成的空腔内增殖,例如肺结核造成的空洞。

This is a fungal abscess of the lung. Note the yellow tan material in the abscess. It is very firm material, because it is composed of fungal hyphae. This one is due to Aspergillus. Aspergillus has a habit of colonizing previously formed cavities, such as those with tuberculosis.

肺曲霉菌感染，可见感染通过脏层胸膜在肺叶之间播散，通向黄棕色霉菌脓肿左边的小动脉形成小血栓并且被出血包围。
曲霉属菌易于侵袭血管及周围组织。

This is Aspergillus infection of the lung. Note how the infection crosses the pleura between the lobes. Note that a small artery to the left of the yellow-brown fungal abscess is thrombosed and surrounded by hemorrhage. Aspergillus likes to invade vessels and surrounding tissues.

可见扩张支气管内的曲霉菌真菌球。

Here is an Aspergillus fungus ball in a dilated bronchus.

高倍放大可见曲霉菌菌丝分叉。

At higher magnification, Aspergillus hyphae are seen to branch.
