Antigen-Antibody Interactions
Salmonella
oxidase negative
catalase positive
facultative anaerobic
Produce acid and gas from fermentation of glucose
BUT NOT LACTOSE
reduce sulfur to H2S
Gram negative bacilli
causes major foodborne outbreaks
typhoid fever
S. enterica Typhi and Paratyphi
diarrhoeal disease
non-typhoid
DynabeadsTM ImmunoMagnetic Separation (IMS)
captures target bacteria using a magnetic field
They are coated with mouse monoclonal antibodies specific for LPS of S. enterica
antibody-antigen interaction
Lateral flow assay
gold nanoparticles (GNP) as the colour marker.
a chromatographic separation of components
antigen-antibody reactions.
a sample pad, a conjugate pad, the reaction membrane, and an absorbent pad
the conjugate pad contains antibodies that are specific to the target molecule, conjugated to colloidal GNPs
