Transmission electron micrographs of the isolated SBSEC phages. (a) TEM image of vB_SbRt-pBovineB21phage showing an icosahedral head (49.2 nm) and a short non-contractile tail (13.3 nm) is indicated by a black arrow. (b) TEM image of vB_SbRt-pBovineS21 phage showing an icosahedral head (46.2 nm) and a short non-contractile tail (12.5 nm) is indicated by a black arrow. The scale bar is 50 nm.
