What does serotype specific mean?
: a group of intimately related microorganisms distinguished by a common set of antigens also : the set of antigens characteristic of such a group.
What is an example of a serotype?
The Salmonella genus of bacteria, for example, has been determined to have over 2600 serotypes. Vibrio cholerae, the species of bacteria that causes cholera, has over 200 serotypes, based on cell antigens. Only two of them have been observed to produce the potent enterotoxin that results in cholera: O1 and O139.
What are the types of serotype?
The most prevalent serotypes were as follows: in humans, serovars Typhimurium and Enteritidis; in cattle, serovars Typhimurium and Dublin; in pigs, serovar Typhimurium; and in chickens, serovars Enteritidis, Infantis, and Typhimurium.
How are serotypes identified?
The serotype is determined by agglutination of the bacteria with specific antisera to identify variants of somatic (O) and flagella (H) antigens. This provides the antigenic formula of the strain associated to the name and subspecies of the serotype.
What is serotype and genotype?
We learned that a serotype is a serologically and antigenically distinct variety of microorganism, like a subgroup of a species of bacteria. Serovar is simply a synonym for serotype. We also learned that a genotype refers to an organism’s genetic makeup or constitution (whether it’s expressed or not).
Is serotype and strain the same?
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). A serotype if also different from genotype which entails the set of genes (a heritable genetic characteristic) of an organism.
What’s the difference between serotype and strain?
Serotypes may be viewed as a further categorization of strains. This is because of the fact that strains of different microorganisms can also have varying antigens and thus a need to categorize this further based on these molecules.
Is serotype the same as strain?
What is strain and serotype?
What is the genotype and phenotype?
A person’s genotype is their unique sequence of DNA. More specifically, this term is used to refer to the two alleles a person has inherited for a particular gene. Phenotype is the detectable expression of this genotype – a patient’s clinical presentation.
What is difference between strain and species?
A strain refers to a genetic variant or subtype of a biological species, while species refers to a group of organisms that can reproduce with one another in nature and produce fertile offspring.
What is the difference between serotype and genotype?
What is the difference between a serotype and a subtype of a virus?
Posted April 24, 2020. 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 called strain?
Strain is the amount of deformation experienced by the body in the direction of force applied, divided by the initial dimensions of the body.
What is molecular serotype?
coli O- and H-types, molecular serotyping generally refers to genetic-based assays targeting O-group-specific genes found within the E. coli O-antigen gene clusters and the H-antigen genes that encode for the different flagellar types.
