In a previous study we evaluated the microbiological quality of water of seven pools in the city of Palermo through evaluation of bacterial indicators of faecal contamination and of protozoa (Giardia and Cryptosporidium). In this study we also searched for the presence of fungi in two swimming pools of a public swimming facility in the same city. Samples were collected from both pools, their filtration systems and floor surfaces of the facility. Chemical-physical and microbiological examination of water of the two pools have shown that quality of water depends on the concentration of residual free chlorine and on the number of bathers in the pool. The values of four microbiological parameters (bacterial load at 22 degrees C and 36 degrees C, presence of coagulase-negative Staphylococci and Pseudomonas spp.) increased with diminishing chlorine concentrations and with increasing number of pool users. Faecal bacteria, Giardia and Cryptosporidium were not found. On the other hand, various fungi were isolated from floor surfaces and pool water even in the presence of optimal chlorine concentrations. This study confirms the importance of regular maintenance of pool disinfection systems and suggests the need to search for other micro-organisms not included in the current legislation (Giardia, Cryptosporidium and fungi).
在之前的一项研究中，我们通过评估粪便污染的细菌指标和原生动物（贾第虫和隐孢子虫），对巴勒莫市七个游泳池的水质进行了评估。在本研究中，我们还在同一城市的一个公共游泳设施的两个游泳池中查找了真菌的存在情况。从两个游泳池、它们的过滤系统以及该设施的地面采集了样本。对两个游泳池的水进行的化学物理和微生物学检查表明，水质取决于游离余氯的浓度和游泳池内游泳者的数量。四个微生物学参数（22摄氏度和36摄氏度下的细菌载量、凝固酶阴性葡萄球菌和假单胞菌属的存在情况）的值随着氯浓度的降低和游泳池使用者数量的增加而升高。未发现粪便细菌、贾第虫和隐孢子虫。另一方面，即使在氯浓度处于最佳水平的情况下，仍从地面和游泳池水中分离出了各种真菌。本研究证实了定期维护游泳池消毒系统的重要性，并表明有必要查找当前法规未涵盖的其他微生物（贾第虫、隐孢子虫和真菌）。
