                            Also, even if the bacteria is not resistant to phages , the antibiotic will still work better.

                              Also, the head is not always an icosahedron; in the T4 podophage used to treat Tom Patterson (read The Perfect Predator) named AbTP3𝚽1, the head is more like a beach ball.
