10 Biological Terms

1. gavage: force feeding by means of a tube
2. motif: a distinctive usually recurrent molecular sequence (as of amino acids or base pairs) or structural elements (as of secondary protein structures)
3. chemotactic: the movement of a microorganism or cell in response to a chemical stimulus
4. downregulation: a decrease in sensitivity, through overexposure, to a drug or other chemical caused by a reduction in the number or density of receptors on cell surfaces
5. linker proteins: proteins that provide mechanisms by which receptors can amplify and regulate downstream effector proteins
6. hyperinfectious: repeated reinfection with larvae produced by parasitic worms already in the body due to the ability of various parasites to complete the life cycle within a single host compare
7. locus: the chromosomal position of a gene as determined by its linear order relative to the other genes on that chromosome
8. serotype: a group of organisms, microorganisms, or cells distinguished by their shared specific antigens as determined by serologic testing
9. inoculate: to implant (a disease agent or antigen) in a person, animal, or plant to produce a disease for study or to stimulate disease resistance
10. precipitation: the precipitating of a substance from a solution
11. precipitate: to separate (a substance) in solid form from a solution, as by means of a reagent

Outline: Host-induced epidemic spread of the cholera bacterium

• Main Result: Having more information and higher understanding of gene expression will give the ability to develop antimicrobial therapies and control transmission of the microbial infections and also develop vaccines to give immunity.

What is the importance or significance of this work? What were the limitations in previous studies that led them to perform this work?

• Methods
  • Sample Collection
  • Competition Assays
