摘　　要：比较鸟籽琼脂 (GASA ,Guizotiaabyssinicaseedagar)和咖啡酸玉米琼脂 (CACA ,Caffeicacidcommealagar)对新生变种和格特变种的培养效果 ,再同时用两种培养基分离鸽粪和澳洲赤桉标本中的新生隐球菌。结果表明 ,CACA对新生隐球菌的培养和选择性分离效果与GASA相同 。The two verities of Crgptococcus neoforinans were first observed as well growing with brown color changes on Guizotia abyssinica seed agar(GASA)and caffeic acid commeal agar(CACA.Then,C.neoformans var.neoformans was found in 18/26 pigeon droppings by both two media.C.neoformans var.gattii was not isolated by the two media in 76 Eucalyptus camaldulensis samples.However,an,overgrowth of filamentous fungus was more frequently seen on GASA.Our results suggest that CACA be capable of selevtively isolating C.neoformans with the advantages of less interference fron the overgrowth of filamentous fungi.
