What are shiga toxin-producing e. Coli?

Dangerous bacteria: Shiga toxin-producing E. coli (STEC) are bacteria found in various livestock (cows, swine, etc) which can lead to dangerous food borne illness.Recent outbreaks in Europe are due to a specific type of STEC called strain 0104:h4. In the USA E. coli o157:h7 is a more common strain.Each produces a toxin (shiga) which can disrupt colon cells causing bloody diarrhea or destroy kidney cells & lead to HUS. ...Read more

Toxin (Definition)

Poisonous substance produced within living cells or organisms;man-made substances created by artificial processes are thus excluded. The term was first used by organic chemist ludwig brieger (1849–1919). For a toxic substance not produced within living organisms, "toxicant" and "toxics" are also sometimes used.[citation needed]. Toxins can be small ...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

Cdiff 4yrs ago - now have LUQ & soft/loose stools. CDIFF TOXIN/GDH W/REFL TO PCR Result: Toxigenic C. difficile detected
New infection or colonized?

Monitor: Once you have C. diff there is a reasonable chance you can be colonized. The criteria for infection include watery stools in excess of 3-4 times daily. The pain or discomfort is usually in the lower abdomen. Soft stools with a relatively low daily frequency usually are not indicative of C. diff. In summary, the presence of C. diff. in your stool in itself is not indicative of infection ...Read more

Clostridium difficile toxin b gene present
clostridium dificile antigen presen. Would u no how severe the c diff is?

Have diarrhea or no?: C.Difficile is pathogenic in older children & adults (whose colonic microflora are altered by antibiotics, chemotherapy, salmonella/shigella). C.Diff causes diarrhea w/pseudomembranous & other colitis, complicates inflammatory bowel disease, causes fulminant transmural extension, perforation with peritonitis, toxic megacolon. Treatment, & confirmation of post-treatment eradication, is recommended. ...Read more

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

Is e. Coli contagious?

Is e. Coli contagious?

The facts: E.coli is a bacteria that is commonly found in the digestive tract of warm & cold blooded animals, including humans. It is commonly spread by fecal contamination. 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

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?

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

Can you tell me are epec, ehec, etec, and eaec extra-intestinal pathogenic e coli?

Can you tell me are epec, ehec, etec, and eaec extra-intestinal pathogenic e coli?

E. coli.: These are all different kinds of E. coli where the first E is always "entero" and the last two are always "E. coli." The second letter is what differs; hemorrhagic, toxigenic, etc. I'm not entirely sure what you mean by extra-intestinal E. coli though? E. coli are most commonly transmitted by a fecal-oral route as they reside in the intestine , but can infect other organs as well. ...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
