This study involved a total of 116 samples, 79 taken from pigeon droppings and 37 of atmospheric air taken close to accumulations of excrement. Cryptococcus neoformans var. grubii was isolated from 11 (13.9%) of these samples. Other species of Cryptococcus were also isolated from these samples, such as C. albidus (12.6%) and C. laurentii (8.9%). C. neoformans was not isolated from the air samples, though C. albidus (5.4%) was. All the strains of C. neoformans were found to belong to the A serotype (C. neoformans var. grubii). In regard to the studies with the antifungal agents 5-fluorocytosine, fluconazole, itraconazole, amphotericin B and voriconazole, by means of the microdilution method (EUCAST), we point out that one sample demonstrated resistance to fluconazole, this being especially significant because this is an environmental strain.
本研究共涉及116个样本,其中79个取自鸽粪,37个取自靠近粪便堆积处的大气空气。从这些样本中的11个(13.9%)分离出新型隐球菌格鲁比变种。还从这些样本中分离出其他隐球菌物种,如浅白隐球菌(12.6%)和罗伦隐球菌(8.9%)。空气样本中未分离出新型隐球菌,但分离出了浅白隐球菌(5.4%)。所有新型隐球菌菌株均属于A血清型(新型隐球菌格鲁比变种)。关于使用抗真菌剂5-氟胞嘧啶、氟康唑、伊曲康唑、两性霉素B和伏立康唑的研究,通过微量稀释法(欧洲抗菌药物敏感性试验委员会),我们指出有一个样本对氟康唑耐药,这一点尤为重要,因为这是一株环境菌株。
