In vivo expressions of ironQS loaded E. tarda strains. (A) Expression of ironQS loaded strain in macrophages J774A.1. The infected cells were observed by inverted fluorescence microscope at different time intervals. (B) Expression of ironQS strain in zebrafish larvae. Zebrafish larvae were immersed in E. tarda(ironQS) suspension and observed by inverted fluorescence microscope at different time intervals. (C) Expression of ironQS strain in adult zebrafish. Zebrafish were intraperitoneally injected with E. tarda(ironQS) suspension. The internal organs were extracted at different time intervals and further analyzed by Western blot using the antibody specific to Katushka.
