数据上的细菌数量在成熟的蛆，prepupulum，pupulum和新兴的成年人繁殖在实验室培养基（CSMA）和自然条件下，在马粪，厕所内容物，和垃圾。成熟的蛆体内通常有107个细菌。在预蛹中，计数福尔斯下降到105或106。在化蛹开始时，计数通常从104到105，并且在变态期间保持这个范围。大多数新出现的苍蝇保留102或103个细菌，而一些是不育的，另一些则有106个细菌。因此，2下降始终出现在细菌的生存模式：在预蛹和新出现的成人。多种寄生植物群的感染模式与单一种细菌的感染或双重感染基本相同。无论是哪种培养基，成虫出现时携带的细菌数量大致相同。
Data are presented on the number of bacteria in mature maggots, prepupae, pupae and emerging adults breeding in laboratory medium (CSMA) and under natural conditions in horse manure, privy contents, and in garbage. Mature maggots typically have 107 bacteria internally. The count falls to 105 or 106 in the prepupa. At the start of pupation, counts are generally from 104 to 105, and this range is maintained during metamorphosis. The majority of emerging flies retain 102 or 103 bacteria, while some are sterile and others have 106. Thus, 2 declines consistently appear in the bacterial survival pattern: in the prepupa and in the newly emerged adult. The pattern of infection with a multiple saprophytic flora is essentially the same as infection with a single species of bacteria or dual infection. Whatever the medium, adults emerged harboring approximately the same number of bacteria.
