no, E. coli does not hydrolyze starch; if you grow a culture on a starch plate and incubate it at 37 Celsius for 24 hours and then flood the plate with iodine, you will see no reactiojn (ie: clear area developing around the growth).

E. Coli bacteria samples which are placed for at least one minute in boiling water at sea level altitude (longer for higher altitudes) are destroyed due to breakdown of the cell wall.

"Col" refers to the colon, and "-itis" is a suffix meaning "inflammation."

Yes -- e coli, which colonizes in the gut, can be inhaled if the infected contents of the gut is present in feces that is exposed to inhaled air, or is present in vomit that is aspirated. E coli can also colonize in the urinary tract and can vaporize into breathable air upon infected urine's release from the body. E coli pneumonia is known to spread in this fashion in chronic-type medical care institutional settings.

no it doesn't

There are several different strains of E. coli, each having about five million (5,000,000) base pairs. For example, uropathogenic E. coli (the one commonly associated with urinary tract infections) has about 5,231,428 base pairs, while E. coli K-12 has 4,639,221. The number of base pairs an organism has in its genes is commonly referred to as genome size. A web search for "genome size E. coli" is how I found these numbers.

Ecoli is a bacteria and can be found in pretty much any food. Most commonly, ecoli is in raw chicken.

My husband recently suffered sweats and rygors twice before being rushed to emergency locally. He was finally diagnosed as e-coli infection in the blood. They do not know how it got there and whether it somehow entered hi blood stream via a mild diverticulitis..not painful and being a vegetarian, something we had not even considered. They think he got run down working on detailing 3 cars over 2 weeks (he's 72) and this allowed his immune system to run down and allow perhaps, the diverticular to host this bacteria enoughn for it to penetrate a small lesion. Which they couldn't see, but figured there's o other way. My husband was on the only antibiotic which responded to this particular strain of e-coli which is cifran for 8 days. This caused side effects and so he stopped it after follow up with our gastro specialist. Just wanted to know if this e-coli could enter blood through or via a lesion inside the backside cheeks which he scratched nightly making it bleed..

E. coli is a gram negative bacteria, meaning that it has a cytoplasmic lipid membrane, a peptidoglycan layer, and a (LPS) lipopolysaccharide layer. As a result, e. coli stains a pink colour on a gram stain from the counterstain saffranin. Gram positives stain purple retain the crystal violet dye even after washed with a decolouring solution.

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

E Coli: Optimum pH [6-7] Minimum 4.4; Maximum 9.0 http://www.textbookofbacteriology.net/nutgro_4.html

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
