The CLSM images of P727 isolate-infected macrophages after separate treatment with culture medium (control), Cy5, Cy5/Oxi-αCD NPs and Cy5/FA-Oxi-αCD NPs for 4 h. RAW264.7 cells were infected with SYTO 9 stained P727 isolate at 37 °C for 4 h, then were incubated with Cy5 (0.05 μg/mL) and Cy5/Oxi-αCD NPs and Cy5/FA-Oxi-αCD NPs (containing 0.05 μg/mL Cy5) at 37 °C for 4 h. DAPI (blue), SYTO 9 (green), Cy5 (red). Scale bar represents 20 μm
