    摘要: This disclosure describes, in one aspect, a composition that includes a transgenic pathogen that expresses a heterologous pathogen associated molecular pattern (PAMP). In some embodiments, the pathogen may be attenuated. In some embodiments, the pathogen can include T. cruzi. In another aspect, this disclosure describes a method of treating an infection in a subject. Generally, the method includes administering to the subject, in an amount effective to treat the infection, a pathogen genetically modified to express a pathogen-associated molecular pattern (PAMP) not natively expressed by the pathogen.

    摘要: The present invention provides methods and compositions to reduce prevalence of plasmids in microbial colonies, including infections, and includes therapeutic compositions, methods for treatment of infections, and methods for identifying additional such compositions. Means are provided to reduce the copy numbers of antibiotic resistance genes, and to confer phage binding to cells lacking receptors for those phage.
