Bacterial Infection
This
type of food borne illness occur when the food
eaten is contaminated with living pathogenic bacteria.
The amount and
type of bacteria will determine the time for symptoms to appear. The
bacteria will pass through your stomach and down into your lover
intestine. It will embed themselves in the wall of the intestine and it
will multiply.
Bacterial infection most often cause diarrhea (sometimes
bloody), stomach cramps and fever.
Typical examples of infectious
bacteria are:
There are
many
other types of infectious bacteria as well. There are over 2,000 types
of Salmonella alone.
NOTE: Bacterial
infection has longer incubation period than bacterial intoxication. It
has gradual onset, usually lasts a few days and fever is often present.

Bacteria
(especially E. coli) may be used to replicate DNA in the form of a
plasmid. This DNA is often chemically modified in vitro then inserted
into bacteria to select for the desired traits and isolate the desired
product from by-products of the reaction. After growing the bacteria
and thereby replicating the DNA, the DNA may be further modified and
inserted into other organisms. More...

Bacteria
grow best in
the temperature range between 4ºC and 60ºC. Temperature below
4ºC, and temperature between 60ºC and 74ºC, will not
kill bacteria, but it will not allow them to multiply enough times to
cause an illness. In order to kill pathogenic bacteria you need
temperatures above 74ºC. Temperature is the easiest factor to
control in order to prevent bacterial growth.
