Hycanthone was found to be an inducer of P22 prophage in Salmonella typhimurium LT-2(P22).

Vibrio cholerae O1 isolates collected during cholera outbreaks occurring from late 2007 to early 2008 in northern Vietnam were revealed to represent an altered strain containing the RS1 element followed by a CTX prophage harboring El Tor type rstR and classical ctxB on the large chromosome.

A staphylococcus typing phage (NCTC 8426) was found to form lysogenic systems with three strains of staphylococci. In the case of two of these strains, staphylococci lysogenically infected with the typing phage were now lysed by the temperate phages they had previously carried. This loss of immunity was due to the replacement of the originally carried prophage by the prophage of phage 8426. Thi...

The sheath of the Serratia entomophila antifeeding prophage, which is pathogenic to the New Zealand grass grub Costelytra zealandica, is a 3-fold helix formed by a 4-fold symmetric repeating motif disposed around a helical inner tube. This structure, determined by electron microscopy and image processing, is distinct from that of the other known morphologically similar bacteriophage sheaths.

We report the draft genome assembly of Enterococcus pernyi The genome sequence is 3.09 Mb in length with a G+C content of 38.35%. It covers 3,153 genes with an average length of 854 bp, and contains 65 tRNAs, 13 small RNAs, and 18 rRNAs. Moreover, it contains 9 genomic islands with an average length of 14,058 bp and 3 prophages with an average length of 37,430 bp.

The presence and assortment of 16 known virulence/resistance genetic determinants carried by prophages or prophage-like elements were tested in 212 clinical group A Streptococcus (GAS) strains and related to available data from SmaI macrorestriction/pulsed-field gel electrophoresis analysis and emm typing. A strong correlation existed among the three analyses. This finding supports the substant...
