Can cooking e coli contaminated food kill the bacteria?

Can cooking e coli contaminated food kill the bacteria?

Yes, proper cooking: Thoroughly cooking foods, and proper food-safety habits, kills e. Coli bacteria. The "bad" e. Coli in food poisoning at first causes intestinal symptoms such as diarrhea. If it goes on to damage the blood and the kidneys, more organs get affected, and skin rashes looking like tiny blood spots or like bruises can appear. This second, serious stage of the illness is called hemolytic uremic syndrome. ...Read more

Stool sample shows heavy growth of nontoxogenic e. Coli & streptococcus salivarius. Is this abnormal/problematic?

Stool sample shows heavy growth of nontoxogenic e. Coli & streptococcus salivarius.  Is this abnormal/problematic?

No: Assuming you are not symptomatic, these bacterial organisms are considered part of the normal gastrointestinal (GI) tract. The GI tract starts at the mouth and ends at the anus. Strep salivarius lives in the mouth whereas E. coli lives in the intestines. In only very rare instances does this strep cause illness. The type of E. Coli mentioned causes UTIs since the urinary and GI tracts are so close ...Read more

Does silver help in killing salmonella or e coli from food?

In vitro, yes but...: In vivo, it would render your fish dish unpalatable and rather expensive. Since silver ions (single free-form silver) produce free radicles that can kill bacteria(the process can be done in a petri dish), it would mean impregnating and infusing your fish with silver- yuck. ...Read more

Does penicillin inhibit e. Coli bacterial growth?

Does penicillin inhibit e. Coli bacterial growth?

Most do.: Although there are e. Coli that are resistant to all penicillin-type antimicrobials, these exist mostly in hospitals. Without the antimicrobial pressure in the health care setting, most e. Coli are quite sensitive to most penicillins even ampicillin. Even though penicillin itself is not very useful for e. Coli, really high doses in the "old days" worked. ...Read more

Its prevalence makes it a marker for contamination of lakes/city water supplies etc. Certain strains are responsible for human disease, but most live harmlessly in your gut. Good personal hygiene/avoiding contaminated sources stops it. ...Read more

What is e coli in water from?

Misdirected sewage: E coli is an inhabitant of the colon and is involved in digestion. It is easily dealt with in modern sewage treatment. If it gets loose into the soil or water supply, then it can become a hazard. It gets there from badly designed or old sewage systems or sometimes from septic systems too close to wells, and other water sources. ...Read more

How is e. Coli sepsis treated?

How is e. Coli sepsis treated?

E. coli: This bacteria can produce a wide variety of infections which are generally treated with antibiotics to which the particular strain of e. Coli is sensitive and which will reach the site of infection effectively. Sepsis is the body's reaction to infection and may require supportive care beyond the antibiotics. ...Read more

Suggests contamination with urogenital or skin flora. 
>100,000 CFU/ml Lactobacillus species.
20,000 CFU/ml mixed gram positive flora. 
What's it mean?

Means contaminated: Urine specimen from the surrounding area around urethra (opening where the urine comes out from). You may want to repeat the test , if your doctor still wants that, get a clean catch specimen, which entails cleansing the area first, passing some urine, then obtain a midstream urine sample, follow the lab instructions for that, best wishes ...Read more

Is GBS a second cause of my UTI? culture results: 10,000 CFU/mL Streptococcus Group B, (S. agalactiae) AND >100,000 CFU/mL Escherichia coli

Is GBS a second cause of my UTI? culture results:  10,000 CFU/mL Streptococcus Group B, (S. agalactiae)	AND >100,000 CFU/mL Escherichia coli

Contamination: Urinary tract infection is usually a single organism. GBS is a normal organism of the vagina. In your case, it is likely that e. coli is the responsible organism for your UTI and GBS is just a contaminant especially that the count is 10,000 ...Read more

Can a e. Coli colony contain flu viruses or other viruses inside the bacteria?

Can a e. Coli colony contain flu viruses or other viruses inside the bacteria?

Not exactly: You're right to prompt the question, in that bacteria can be made more virulent by uptake of "signals" from a bacteriophage. Also, an e.Coli infection does not preclude a superimposed or secondary viral illness--which together compromises the host patient more than a single infection might. However, flu viruses can not live within e.Coli. ...Read more
