A serotype or serovar is a distinct variation within a species of bacteria or virus or among immune cells of different individuals.

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).

Different serovars of enteric bacteria—such as E. coli and Salmonella enterica, for example—are often found to be associated with the ability to inhabit…

Serovars are distinct variations within a species of bacteria or viruses, identified by differences in their surface antigens. They are used to classify microorganisms for epidemiological studies and disease tracking.

Serotyping is a subtyping test based on differences in microbial (e.g., viral or bacterial) surfaces. Serology refers to the antibodies that form because of a viral or bacterial infection. Serotyping is sometimes referred to as serology, but this is technically inaccurate.

All are gram-negative, motile aerobic spirochetes. The serovar pomona is the most common cause of clinical leptospirosis in swine, and the serovar bratislava is commonly found in serologic surveys and sometimes correlated with clinical disease. There are several other serovars, which are typically maintained in other mammalian hosts but are ...

2023年6月28日 · We developed a novel algorithm for serotype prediction, implemented as an R package (Seroplacer), which takes as input full-length 16S rRNA gene sequences and outputs serovar predictions after phylogenetic placement into a reference phylogeny.

A serovar or serotype is a grouping of microorganisms or viruses based on their cell surface antigens. Serovars allow organisms to be classified at the sub-species level; an issue of particular importance in epidemiology.

Serovars, as the name implies, are classified using serological testing and not DNA. Over the last decade a lot of DNA work has been done on the leptospira ‘family tree’ and the one clear outcome is that the serogroups and serovars are often genetically diverse.
