The co-existence of microbial communities and populations showing high, medium, and low levels of parasitic variability (PV) in mineral and muck soils with different soil health conditions in Michigan vegetable production fields is established. However, if PV relates or not to bacterial communities is unknown. This study characterized bacterial communities present on and in the body of nine field and greenhouse sub-populations isolated from the mineral and muck fields. We utilized a high throughput sequencing of 16S rDNA. Results showed a variable composition (or abundance) of 65 genera in the field and 61 genera in the greenhouse isolates, with 12 genera of unknown and the rest belonging to 14 known functional groups. The medium- and low-PV populations shared more bacterial composition than either one with the high-PV population. Thus, laying a foundation for an in-depth understanding of if the observed associations have any role in cause-and-effect relationships with PV.
在密歇根州蔬菜生产田不同土壤健康状况的矿质土和泥灰土中，已证实存在微生物群落以及呈现高、中、低水平寄生变异性（PV）的种群。然而，PV是否与细菌群落相关尚不清楚。本研究对从矿质土和泥灰土田地分离出的9个田间和温室亚种群的体表和体内存在的细菌群落进行了特征分析。我们利用16S rDNA的高通量测序。结果显示，田间分离株中有65个属的组成（或丰度）可变，温室分离株中有61个属，其中12个属未知，其余属于14个已知功能组。中低PV种群比高PV种群共享更多的细菌组成。因此，为深入了解观察到的关联是否在与PV的因果关系中起任何作用奠定了基础。
