E Coli Infections

E.coli genome constist of a SINGLE circular chromosome containing 4.6 Mb i.e. 4.6 X 10^6 bases.

The weight of one base is 330 daltons and 1 Dalton is equal to 1.661^-24g. there fore the CHROMOSOMAL WEIGHT (in micrograms) is 660 X 1.661 X 10^-18 X 4.6 X 10^6

which is equal to 5.043 X 10^-9 MICROGRAMS.

N is the answer. The pattern is the last letter of each number starting with one (e) then two (o)

The genes that produce the enzymes needed to break down lactose are not expressed.

It can't smell. It's bacteria. They have no nose.

rule out MRSA and VRSA, reconfirm. You'd have to me more specific on the antibiotics you've taken. a hospital can do all this. so if you're asking here, you haven't asked your doctor, or it's not a UTI

Under optimal growth conditions the doubling time for E. coli is 20 minutes. This is however, a textbook figure and in practice the doubling time is slightly longer. Under standard, non-bioreactor type laboratory conditions, aerated (shaking) E coli cultures grown in LB or similar media will have a doubling time of around 30 minutes. Note that growth rates differ between strains, B strain derivatives (often used for protein expression) grow faster than K strain derivatives (generally used for cloning). Also, strains harboring plasmids and strains grown under selective pressure will often have longer doubling times.

e.coli can harm humans through - contaminated food, eating undercooked, contaminated ground beef, un-pasturized milk, swimming in or drinking contaminated water, and eating contaminated vegetables

Fermentative, with gas production.

E. coli is streptobacillus. Staphylobacillus does not exist because bacillus cells only divide across the short axis, so the staphylo- (cluster-like) arrangement does not exist for bacillus.

its genes are well known

All refrigerated delivery trucks were requires to have a record-keeping thermometer mounted inside

It is possible to get e coli from anything that you eat, plant or animal.

Bacteria

Cell membrane, pilli, and ribosomes are common structures found in E. coli. Also, nucleolus and plasmids are found in E. coli.

the bacteria travels into the bloodstream and makes you sick. The symptoms are fever, vomiting, and bloody diarrhea

A gastrointestinal infection? probably if there is poor hygiene as E.Coli can be transferred via fecal-orally. A urinary tract infection? probably if u have underlying disorders or maybe suppressed immune system.

You would expect to find it in the plate labeled LB-, because that specific plate is the control plate, meaning it has nothing added to it, like the amipicilin or pFlouroGreen plasmid.

in nature, where does e coli grow

Cook foods to the FDA Temperature

Chill foods in the fridge

Clean foods before cooking

Prevent cross contamination by washing food preparation stuff

Wash hands before making food

Do not pool eggs or meats

Use proper slaughtering hygeine

Pasteurize beverages

E. coli is the most common pathogen encountered in urinary tract infection. Invasive strains of E. coli causes bacillary dysentery.

Motile according to the Motility-Indole-Ornithine Test.
