Intracellular parasitism of chlamydiae:: Specific infectivity of chlamydiaphage Chp2 in Chlamydophila abortus

The obligate intracellular nature of chlamydiae presents challenges to the characterization of its phages, which are potential tools for a genetic transfer system. An assay for phage infectivity is described, and the infectious properties of phage Chp2 were determined.
