revealed mostly 2 types, PT8 (n = 8) and PT13a (n = 4), for strains with the JEGX01.
Analysis of Salmonella enterica serotype Typhimurium by phage typing

In Canada, where phage typing
is the predominant subtyping method used, phage type 31 accounts for 9% of isolates tested (6).
was done for the isolates collected during 2002-2005 and 2007.
Antimicrobial drug sensitivity testing, phage typing
, and MLVA typing of isolates produced results indistinguishable from those of the outbreak strain.

Application of phage typing
and pulsed-field gel electrophoresis to analyse Salmonella enterica isolates from a suspected outbreak in Lagos, Nigeria.
of the E cholerae isolates was carried out using Basu and Mukherjee's (8) and new phage typing
Authors thank the Director, National Institute of Communicable Diseases, Delhi, for the detection of Vibrio cholerae organisms as a part of quality control from some of the rectal swab samples sent from this hospital, the Director, National Institute of Cholera and Enteric Diseases, Kolkata, for serological confirmation and phage typing
of the submitted strains.
By using Vi-phage typing
according to the International Federation for Enteric Phage Typing
and biotyping were done at the National Salmonella Phage Typing
Centre, Department of Microbiology, Lady Hardinge Medical College, New Delhi.
The phenotypic tests, including antimicrobial-drug resistance profiles and phage typing
, are usually considered very stable and therefore often used for surveillance of S.
Similar results were obtained with phage typing
of a convenience sample of 31 isolates by Rafiq Ahmed at the National Microbiology Laboratory, Winnipeg, Manitoba, Canada.
Identification, serotyping, phage typing
, and susceptibility testing were done as described (8,11,12).
Because only a few subtypes identified by PFGE and phage typing
account for most infections, we included MLVA typing in the routine surveillance in a 2-year period beginning December 2003.
