The Kauffmann–White classification or Kauffmann and White classification scheme [1] [2] is a system that classifies the genus Salmonella into serotypes, based on surface antigens. It is named after Philip Bruce White and Fritz Kauffmann . First the "O" antigen type is determined based on oligosaccharides associated with lipopolysaccharide.
The analytical profile index (API) was invented in the 1970s in the United States by Pierre Janin of Analytab Products Inc. [2] The API test system is currently manufactured by bioMérieux. [3] The API range introduced a standardized and miniaturized version of existing techniques, which were considered complicated to perform and difficult to read.
Salmonella species are intracellular pathogens, [6] of which certain serotypes cause illness such as salmonellosis. Most infections are due to the ingestion of food contaminated by feces. Typhoidal Salmonella serotypes can only be transferred between humans and can cause foodborne illness as well as typhoid and paratyphoid fever.
If calculator gadget is not enabled, should just show the x_default and y_default values. Supports all the same parameters as {{ Superimpose }} except x and y are now formulas, and there are two new parameters: x_default and y_default for the initial x and y values.
Typhidot is a medical test consisting of a dot ELISA kit [1] that detects IgM and IgG antibodies against the outer membrane protein (OMP) of the Salmonella typhi.The typhidot test becomes positive within 2–3 days of infection and separately identifies IgM and IgG antibodies.
Enterobacteriaceae is a large family of Gram-negative bacteria.It includes over 30 genera and more than 100 species. Its classification above the level of family is still a subject of debate, but one classification places it in the order Enterobacterales of the class Gammaproteobacteria in the phylum Pseudomonadota.
Salmonella spp appear to be yellow or colourless colonies, often with a dark centre. As there are many bacteria that also look like Salmonella on DCA, it is widely recommended that more selective agars are used for the identification of Salmonella, namely xylose lysine deoxycholate (XLD) agar. This growth medium is heat-sensitive and should be ...
