| 释义 | phage noun[ C ] biology specializeduk /feɪdʒ/ us /feɪdʒ/ short for bacteriophage; a virus that grows and divides inside a bacterium, destroying it : （同bacteriophage） Scientists have known for years that these viruses, known as phages, are able to kill bacteria, but the mechanism was not understood. Bacteria-killing viruses known as phages offer hope in the problem of antibiotic resistance. The phages do the same thing antibiotics do - they disrupt bacterial cell walls. Because phages contain DNA, they could prove more adaptable than traditional antibiotic drugs, Young said. Phage therapy was suggested by the patient's mother.

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. Overlapping clones (four phages) spanning 22 kb were recovered. Phage therapy revisited : the population biology of a bacterial infection and its treatment with bacteriophage and antibiotics. Outbreak-associated strains showed a coincident phage type, antibiotype and pulse-field gel electrophoresis pattern. In conclusion, internal genome pressure is one of the key determining factors for phage infectivity and capsid stability. Increasing and decreasing protein stability - effects of refertant substitutions on the thermal-denaturation of phage lambda-repressor. Effects of condensing agent and nuclease on the extent of ejection from phage lambda. Molecular typing methods are widely used to supplement more established typing methods such as phage and serotyping and to support epidemiological investigations of listeriosis.
