Phage typing of Salmonella Typhimurium - is it still a useful tool for surveillance and outbreak investigation?
Phage typing has for decades been useful as a phenotypical, definitive method for epidemiological characterisation of Salmonella Typhimurium. The system recommended by the World Health Organization (WHO) Collaborative Centre for phage typing of Salmonella has, however, become rather complex, and the present study illustrates the challenges of sufficient standardisation of the interpretation of ...
متن کاملDefining the Core Genome of Salmonella enterica Serovar Typhimurium for Genomic Surveillance and Epidemiological Typing.
Salmonella enterica serovar Typhimurium is the most common Salmonella serovar causing foodborne infections in Australia and many other countries. Twenty-one S. Typhimurium strains from Salmonella reference collection A (SARA) were analyzed using Illumina high-throughput genome sequencing. Single nucleotide polymorphisms (SNPs) in 21 SARA strains ranged from 46 to 11,916 SNPs, with an average of...
متن کاملPhage typing scheme for Salmonella braenderup.
A phage typing scheme for Salmonella braenderup based on both phage sensitivity and lysogenicity patterns is presented. Three S. braenderup symbiotic phages (br A, br B, and br C) were used in the phage sensitivity test, and three indicator strains were used for the lysogenicity test. The 424 strains examined were grouped in 15 of 64 possible types within this scheme. The most frequent types we...
متن کاملMultilocus Sequence Typing of the Clinical Isolates of Salmonella Enterica Serovar Typhimurium in Tehran Hospitals
Background: Salmonella enterica serovar Typhimurium is one of the most important serovars of Salmonella enterica and is associated with human salmonellosis worldwide. Many epidemiological studies have focused on the characteristics of Salmonella Typhimurium in many countries as well as in Asia. This study was conducted to investigate the genetic characteristics of Salmonella Typhimurium using m...
متن کاملCRISPR Typing and Subtyping for Improved Laboratory Surveillance of Salmonella Infections
Laboratory surveillance systems for salmonellosis should ideally be based on the rapid serotyping and subtyping of isolates. However, current typing methods are limited in both speed and precision. Using 783 strains and isolates belonging to 130 serotypes, we show here that a new family of DNA repeats named CRISPR (clustered regularly interspaced short palindromic repeats) is highly polymorphic...
