Escheridia Coli Pathogen
I need description of Escheridia Coli(E. Coli) Pathogen. I need it's
size, shape, organismic grouping (singles, pairs etc...), Gram stain
reaction, nutrition, response to oxygen, life cycle.
Can't wait to get the answers. Thanks.
This is from a college microbiology text by R.M. Atlas: Microbiology:
Fundamentals and Applications. The entry is for the genus Escherichia.
Straight rods, 1.1-1.5 by 2.0-6.0 microns, occurring singly or in pairs.
Gram negative. Motile or nonmotile. Acetate acceptable as sole carbon
source, but citrate not acceptable. Glucose and other carbohydrates are
fermented with production of lactic, acetic, and formic acids. L
Facultative anaerobes. Escherichia reproduce mostly asexually by binary
fission, but some strains can reproduce sexually by conjugation. This
process involves transfer of DNA from a donor strain to a recipient via
the F (or sex) pilus.
