Tenacity studies of Cryptococcus neoformans in bird droppings originated from different ornamental birds and chickens showed that there is less chance for this fungus species to survive in non-sterile or bacteria-free droppings of large parakeets and chickens in comparison with droppings of small parakeets. Survival rates of Cr. neoformans in buffer solutions with pH-values ranging from 8.5-9.5 allow to conclude that this species is not alkali-sensitive. Therefore, the increase of pH is not regarded responsible for the survival of Cr. neoformans in bird droppings. Possibly fungistatic substances present in droppings are involved.
对源自不同观赏鸟和鸡的鸟粪中新型隐球菌的韧性研究表明，与小长尾鹦鹉的粪便相比，这种真菌在大长尾鹦鹉和鸡的非无菌或无菌粪便中存活的机会较小。新型隐球菌在pH值为8.5 - 9.5的缓冲溶液中的存活率表明该物种对碱不敏感。因此，pH值的升高与新型隐球菌在鸟粪中的存活无关。粪便中可能存在的抑菌物质可能与之有关。
