Serotypes and the Importance of Serotyping Salmonella
Laboratory experts serotype the Salmonella from infected people. When cases with one serotype increase, they suspect an outbreak and disease detectives start their investigation. Serotyping has been the core of public health monitoring of Salmonella infections for over 50 years.
Kauffman–White classification - Wikipedia
The Kauffmann–White classification or Kauffmann and White classification scheme [1][2] is a system that classifies the genus Salmonella into serotypes, based on surface antigens. It is named after Philip Bruce White and Fritz Kauffmann [de]. First the "O" antigen type is determined based on oligosaccharides associated with lipopolysaccharide.
Salmonella Serotyping; Comparison of the Traditional Method to …
Here, we compared a microarray method using molecular markers, the Check and Trace Salmonella assay (CTS) and a WGS-based serotype prediction tool that targets molecular determinants of serotype (SeqSero) to the traditional phenotypic method using 100 strains representing 45 common and uncommon serotypes.
Serotyping is one of the classic tools for epidemiological study and is applied to numerous species that express different serotypes, such as: Escherichia coli, Pseudomonas aeruginosa, Salmonella species, Shigella species, Yersinia and Vibrio cholerae. Expertise in Serotyping With an extensive range of immune sera for serotyping,
Serotypes. Salmonella spp. are serotyped according to their O (somatic), Vi (capsular), if present, and H (flagellar) antigens (Figure 1). The antigenic formulas of Salmonella serotypes are listed in a document called the Kauffmann-White Scheme. Updating this scheme is the
Genome-based Salmonella serotyping as the new gold …
Mar 9, 2020 · In this study we evaluated two genome-based in silico approaches and their combination for predicting Salmonella serotypes and their suitability for replacing classical serotyping.
Salmonella Nomenclature - PMC
In approximately 35,000 of these cases, Salmonella isolates are serotyped by public health laboratories and the results are electronically transmitted to the Centers for Disease Control and Prevention (CDC).
Whole-Genome-Based Survey for Polyphyletic Serovars of Salmonella …
Abstract. Serotyping has traditionally been considered the basis for surveillance of Salmonella, but it cannot distinguish distinct lineages sharing the same serovar that vary in host range, pathogenicity and epidemiology.However, polyphyletic …
r both of two forms, phase 1 and phase 2. There are over 1800 known serovars which current classi. ication considers being separate species. The organisms t. e O antigen (additional surface antigen). It is present in a few serovars, the most important being Salmonella Typhi, but also present in Sal. the O anti. (1st phase) and the.
SSP: An In Silico Tool for Salmonella Species Serotyping Using …
Jul 15, 2023 · Combination of 47 O and 114 H antigens leads to ∼2500 Salmonella species serovars. SSP web tool is developed to predict serovars using genotype-serotype specificity. Salmonella protein sequences and patterns are used to identify O and H types. 99.72% prediction accuracy is seen for 2136 whole proteomes covering 740 species.
