What is a serogroup of bacteria?
[sēr´o-gro̳p] 1. a group of bacteria containing a common antigen, sometimes including more than one serotype, species, or genus. This is an unofficial designation, used in the classification of certain genera of bacteria, such as Leptospira, Salmonella, Shigella, and Streptococcus.
What is difference between serotype and serovar?
is that serotype is a group of microorganisms characterised by a specific set of antigens while serovar is a group of microorganisms characterised by a specific set of antigens.
What is biotype and serotype?
We learned that a serotype is a serologically and antigenically distinct variety of microorganism, like a subgroup of a species of bacteria. And, finally, we learned that a biotype is a strain, distinguished from other microorganisms of the same species, by its physiological properties.
How is serotyping done?
Serotyping is typically performed by slide agglutination using sets of O, H and K antisera, and the resulting combination of antigens defines the serotype (also called serovar).
What is the difference between serotype and subtype?
While subtype is simply a broad term for any subclassification under a group, a serotype is a grouping of viruses or other microorganisms based on the type of surface antigens present. Serotyping can be done using a variety of assays, including ELISA and RT-PCR.
What is a biotype in microbiology?
A biotype is a strain distinguished from other microorganisms of the same species by its physiological properties. Biotype can also be taken to mean a group of organisms with the same genotype.
What is the role of serotyping in clinical diagnosis?
Abstract. Serotyping has been used to categorize most pathogenic members of Pasteurellaceae of human or animal importance. In particular, serotyping of isolates from vaccine breaks is of primary importance to ensure that vaccines used are covering outbreak isolates in the region.
What is the meaning of the word serotype?
A group of closely related microorganisms distinguished by a characteristic set of antigens. Also called serovar. To classify according to serotype; assign to a particular serotype.

How are microorganisms classified according to their serotype?
Serotype. These microorganisms, viruses, or cells are classified together based on their cell surface antigens, allowing the epidemiologic classification of organisms to the sub-species level. A group of serovars with common antigens is called a serogroup or sometimes serocomplex .
How is the serotype of Salmonella bacteria determined?
The serotype of the salmonella bacteria can be determined by noticing which mixture causes clumps to form. Serotypes refer to separate groups within a species of microorganisms that all have the same antigens on their surfaces.
How is serotyping used to diagnose Y enterocolitica?
Serotyping based mainly on the surface O antigenic variation of lipopolysaccharides (LPS) in the cell wall is widely used for Y. enterocolitica. Subdivision of Yersinia species to serotypes provides useful information concerning their potential pathogenicity and possible reservoir. Y. enterocolitica comprises over 30 serotypes.
