Serienstamm
Serienstamm is a term used in microbiology to describe a bacterial strain that is classified by its serotype, the specific antigenic properties displayed on the organism’s surface and detectable by serological methods. This classification highlights differences in surface antigens such as polysaccharide capsules, lipopolysaccharide O-antigens, and flagellar antigens, which can influence immune recognition and interactions with hosts.
In practice, a serienstamm distinguishes strains within a species that share a common genetic background but
Serotyping is achieved through several laboratory approaches. Traditional agglutination tests use antisera that bind to specific
Limitations of serotyping include cross-reactivity between antigens that can blur distinctions, antigenic variation within a serotype
