Lysogenic conversion by filamentous phage encoding cholera toxin.
Lysogenic conversion by a filamentous phage encoding cholera toxin.
The hallmark of the phages' genome structure is genetic mosaicism, reflecting non-homologous recombination events in their ancestry.
Thirteen different phage types were identified among chicken nugget and strip consumers and six were identified among those reporting consumption of undercooked eggs.
In addition, experiments were monitored as a function of phage progeny release rather than turbidity decline.
Virtually all of those prominent in the phage field in the 1950s and 1960s, and still living, have contributed to it.
The library titre was 1.6r106 pfu/ml with 89 % recombinant phage as judged by blue/white colour selection.
The plates were then inoculated with respective phages using a multipoint inoculator.
