FIG 1.

Transmission electron micrograph images of the atypical S. thermophilus phages CHPC577, CHPC926, and CHPC1151, of the pac-type phage CHPC1246, and of the cos-type phages CHPC1014 and CHPC1046. The previously described S. thermophilus phage 5093 (described in reference 7) and the L. lactis phage P335 (described in reference 13) are also shown on the right side. Phages were negatively stained with 1% uranyl acetate. The symbols indicate distinct baseplate structures (asterisks), flexible globular baseplate appendices (arrows), and single central tail fibers (triangles). Head and tail sizes are indicated in nanometers.
