Two bacterial species (Pseudomonas aeruginosa and Bacillus subtilis) isolated from pigeon droppings, displayed anti Cryptococcus neoformans activity on 4 of 6 media and sterilized pigeon droppings. Acanthamoeba palestinensis trophozoites isolated from pigeon droppings ingested and killed 99.9% of C neoformans cells after 7 days of incubation. Mites and sow bugs (Metoponorthus pruinosus) isolated from pigeon droppings appear to be fungivorous. These findings suggest that many organisms that occur in pigeon droppings influence C. neoformans persistence, reproduction, morphology and distribution in nature.
从鸽粪中分离出的两种细菌（铜绿假单胞菌和枯草芽孢杆菌）在6种培养基中的4种以及灭菌鸽粪上表现出抗新型隐球菌活性。从鸽粪中分离出的巴勒斯坦棘阿米巴滋养体在培养7天后摄取并杀死了99.9%的新型隐球菌细胞。从鸽粪中分离出的螨虫和鼠妇（ pruinosus）似乎以真菌为食。这些发现表明，鸽粪中存在的许多生物体影响着新型隐球菌在自然界中的存活、繁殖、形态和分布。
