An account is given to two pairs of C. neoformans strains on two different bird manure filtrate agars, i.e. pigeon manure filtrate and canary manure filtrate agar. Basidiospore formation was observed in both pairs after 3 d incubation at 26 degrees C on both media. 0.1% biphenyl in pigeon manure filtrate agar showed an inhibitory activity on the formation of the perfect state of the C. neoformans pairs tested. Concentrated pigeon manure filtrate allowed growth of the imperfect, however not of the perfect state of C. neoformans. On canary manure filtrate agar, a brown color effect (BCE) of the colonies of the C. neoformans strains was observed in addition to their formation of the perfect state. Except for a known self-fertile strain no self-fertility could be seen in 40 C. neoformans strains on pigeon manure filtrate agar. Attention is drawn to the risk of laboratory infection when handling the perfect state of C. neoformans.
本文介绍了两对新型隐球菌菌株在两种不同鸟粪滤液琼脂上的情况，即鸽粪滤液琼脂和金丝雀粪滤液琼脂。在两种培养基上于26℃培养3天后，在这两对菌株中均观察到了担孢子形成。鸽粪滤液琼脂中0.1%的联苯对所测试的新型隐球菌菌株对的完美状态形成具有抑制活性。浓缩的鸽粪滤液能使新型隐球菌的不完美状态生长，但不能使其完美状态生长。在金丝雀粪滤液琼脂上，除了新型隐球菌菌株形成完美状态外，还观察到了其菌落的棕色效应（BCE）。在鸽粪滤液琼脂上，除了一株已知的自育菌株外，在40株新型隐球菌菌株中未观察到自育现象。文中提请注意在处理新型隐球菌完美状态时的实验室感染风险。
