The invention encompasses compositions, kits and methods for modifying bacteria, preferably naturally occurring bacteria, in situ. These can be used to treat, prevent or cure microbiome-associated diseases or disorders by modulating the molecules expressed and/or secreted by bacterial populations of the microbiome in a specific manner. The genomic modifications can modify the interactions between part or all of these populations and the host in a way that decreases their deleterious potential on host health. The compositions, kits and methods of the invention do not result in the direct death of these populations or a direct significant inhibition of their growth. The invention further includes methods for screening for genetic modifications in the bacteria, for determining the efficiency of vectors at inducing these genetic mutations, and for determining the effects of these mutations on bacterial growth.
本发明包括原位修饰细菌(最好是天然存在的细菌)的组合物、试剂盒和方法。通过以特定方式调节微生物组细菌群表达和/或分泌的分子,可用于治疗、预防或治愈与微生物组相关的疾病或失调。基因组修饰可以改变部分或全部这些菌群与宿主之间的相互作用,从而降低它们对宿主健康的潜在危害。本发明的组合物、试剂盒和方法不会导致这些种群直接死亡或直接显著抑制其生长。本发明还包括筛选细菌中的基因修饰、确定载体诱导这些基因突变的效率以及确定这些突变对细菌生长的影响的方法。
