Immunofluorescence microscopy of the enterococcal strains labeled with anti-1209 serum coupled with fluorescein isothiocyanate (FITC) (green); cells are stained with Evans blue. (A) A1 ΔEFAU004_01209. No signal is detected. A2 relative phase channel (B) B1 Anti-CcpA serum on total protein extracts of the E. faecalis JH2-2 strain; no immunofluorescence signal is detected due to the cytoplasmic localization of the CcpA protein. B2 Relative phase channel (C) C1 AUS0004 wild-type strain shows green fluorescence, indicating a possible surface localization of the EFAU004_1209 protein. C2 relative phase channel (D) D1 Triple mutant Δ1050-1150-494. D2 Relative phase channel.
