toxin that induces vomiting
harmful exotoxin that binds to MHC II antigen T-cell and produced inflammatory compounds
toxin composed by the A (active) and B (binding) components when cell is engulfed, A is liberated and damages the cell
Disease that is caused by the ingestion of a food with a toxin (usually bacterial) causing vomiting/diarreah in about 4-8 h, lasts 24-48 h
Toxin that is released by the bacteria into the medium (intestine) or the food
group of symptoms usually caused by gastrointestinal infection, such as cramps, diarrhea, vomiting, weaknesses, etc
toxin that affects the nerves or the nervous tissue
2 or more cases of a disease caused by a single food
Disease caused by the ingestion of a food contaminated with viable bact, that reproduce in the GI tract causing fever, diarrhea, vomiting, cramps
Hemolytic Uremic Syndrome, caused by verotoxins of EHEC
toxin that acts on the GI tract
Humoral Immune System
Defense of the body that includes the production of different immunoglobulins, such as IgG, IgA, IgH
Attachment and Effacement
System by which EPEC colonizes the intestinal tract by attaching to the int. cell with capsule and sloughing off the lining of the intestine
is when the membrane of the intestinal cell forms a pseudopod with actin in order to start the engulfing of bacteria
toxin that induces fever
Entero Pathogenic E.coli
Entero Hemorragic E.coli
virulence associated with Salmonella
the decimal reduction time, time required to destroy 90% of the organisms or 1 log cycle
the degrees Fahrenheit required for the thermal destruction curve to traverse one log cycle
time in minutes required to destroy a given number of the organisms in a specfic food product at 250F (121C)
Viable cells consumed, relatively long onset for symptoms, relatively long duration, fever common symptom
Viable cells may not be present, quicker onset time, often short duration, no fever
Thermal Death Time (TDT)
time necessary to kill a given number of organisms at a specific temperature.
