Serotyping is the process of determining the serotype of an organism, using prepared antisera that bind to a set of known antigens. Some antisera detect multiple known antigens and are known as polyvalent or broad; others are monovalent.

Serotyping has been the core of public health monitoring of Salmonella infections for over 50 years. Now, scientists use DNA testing to further divide each serotype into more subtypes and to detect more outbreaks.

Therefore, a serotype is the term used to refer to a group of organisms within a species that have the same type and number of surface antigens. Serotypes are different from strains, which have been described as single isolates from pure cultures or simply as distinct isolates of specific phenotypic/genotypic traits (or both).

Serotyping is the classic tools for epidemiological study of organisms having multiple serotypes: E. coli, Salmonella, Vibrio, Shigella, S. pneumoniae.

2024年4月5日 · Accurate detection and serotyping are essential for epidemiologic study of Streptococcus pneumoniae (pneumococcus). CDC provides multiple resources to detect the bacteria and identify serotypes using polymerase chain reaction (PCR) methods.

Serotyping refers to the grouping of variants of species of bacteria or viruses based on shared surface antigens that are identified using immunologic methodologies such as enzyme-linked immunosorbent assay (ELISA) and Western blotting.

Serotyping is one of the classic tools for epidemiological study. For more than 20 years, Bio-Rad Laboratories, Inc., has offered tools for the accurate identification of microorganisms important in human disease, veterinary science, and food and water safety.

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.

2023年11月21日 · Serotypes are groups of a microorganism that all have the same antigens composition on their surface. What is a Serotype? Humans have an immune system with different cell types, organs, and...

2020年3月9日 · We found that SeqSero and seven gene MLST showed 98% and 95% concordance, respectively, with classical serotyping for the here evaluated serotypes, including the most common German serotypes S....
