The restriction maps of phage 3A and that of phage 77 are linear, whereas that of phage 53 is circular and exhibits a circular permutation.
Released phage particles attach avidly to the outer leaflet of the outer membranes of lysed and unlysed Chlamydiae at different stages of development, suggesting the presence of specific phage receptors in the outer membrane uniformly during the chlamydial developmental cycle.
On the contrary, the extent of inactivation of phage virulence was proportional to the degree of polymerization.

Adsorption of the phage to its host followed a biphasic kinetics and its intracellular growth was characterized by a latent period of 15 min and a burst size of 100 particles per infected cell.
Phage sensitivity was not correlated with the presence of plasmids, at least in host strains of serotypes c and e.
The induced prophage was morphologically not distinguishable from the virulent phages of Str.

 Phage Therapy as Antibiotics   (Site not responding. Last check: 2007-10-16)
Phage therapy was tried extensively and many successes were reported for a variety of diseases, including dysentery, typhoid and paratyphoid fevers, cholera, and pyogenic (pus-producing) and urinary-tract infections.
However, it was clear that the phages readily got into the body from the digestive tract and multiplied internally wherever appropriate bacteria were present, as measured by their presence in blood and urine as well as by therapeutic effects (Weber-Dabrowska et al, 1987).
In addition, therapeutic phages should be characterized at least by electron microscopy." While it seems premature to generally introduce injectible phage preparations in the West without further extensive research, their carefully-implemented use for a variety of agricultural purposes and in external applications could potentially help reduce the emergence of antibiotic-resistant strains.

 Myoviridae
The genus includes about 20 phages of enterobacteria (Escherichia, Salmonella, Yersinia) that are either strains of the Enterobacteria phage P2 or may represent independent species, notably:
Tailed viruses resemble Herpesviridae in morphogenesis (use of scaffolding proteins, packageging of DNA into preformed shells, maturation of procapsids by proteolytic cleavage, and capsid expansion) and flow of replication.
In addition, temperate tailed phages and Herpesviridae are able to establish latent infections.
