Sixty-six fungal species in addition to two species varieties belonging to 31 genera were isolated during the current study from water closet (WC) sewage samples (39 species and two varieties in 20 genera) and WC air (53 species and two varieties in 25 genera). There were more fungi in the WC air than in sewage. The most prevalent fungi in WC sewage and air were members of the genera Aspergillus, Cladosporium and Penicillium. Acremonium, Alternaria, Emericella, Mycosphaerella and Pleospora were dominant only in WC air. Some species of these genera are considered to be true or opportunistic pathogens. The pollution level due to the bacterial flora either in the air or in the sewage of WCs was relatively higher than that of the fungal flora. Testing the capability to produce urease, nearly all fungal isolates (65 out of 67) and bacteria tested (35 out of 36) proved to be good urease producers.
在本研究中，从抽水马桶（WC）污水样本（20个属中的39种和两个变种）和WC空气（25个属中的53种和两个变种）中分离出除两个种变种外属于31个属的66种真菌。WC空气中的真菌比污水中的多。WC污水和空气中最常见的真菌是曲霉属、枝孢属和青霉属的成员。顶孢霉属、链格孢属、黄曲霉、球腔菌属和格孢腔菌属仅在WC空气中占主导地位。这些属中的一些物种被认为是真正的或机会性病原体。WC空气中或污水中的细菌菌群造成的污染水平相对高于真菌菌群。测试产生脲酶的能力时，几乎所有测试的真菌分离株（67株中的65株）和细菌（36株中的35株）都被证明是脲酶的良好生产者。
