E Coli Morphology
As used in pathology, this is the abnormal shapes and arrangements of organs, tissues, cells, and components of cells that enable the diagnosis of disease and help to understand its impact. Some diseases involve only abnormal function of normal-appearing parts and thus ...Read more
Depends on serotype: Different serotypes of e.Coli survive and grow at different temperatures, usually 44.5 c. For additional details please see http://www.Ncbi.Nlm.Nih.Gov/pmc/articles/pmc267801/pdf/jcm00052-0174.Pdf. ...Read more
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 moreSee 2 more doctor answers
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
UTI caused by E.coli: E. Coli are the most common bacteria and normal inhabitants of the large bowel. These bacteria often reach the bladder, most commonly in females, where they can multiply & cause an infection. Hence advice for women to wipe front to back, and empty bladder after sex. ...Read moreSee 1 more doctor answer
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
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
Bacterial cause.: Urinary tract infections occur when pathogenic bacteria proliferate in the urine, causing inflammation in the urethra, bladder and sometimes the kidney. E. Coli is the most common cause, which is usually found in the colon but can contaminate the urine since the urethra and anus are in such close proximity. Infections are cleared with antibiotics, and should be confirmed by urine culture. ...Read more
Gram-negative bacteria such as escherichia coli or klebsiella pneumoniae on the zone diameter interpretive chart, what does this mean?
Zone diameter chart: I do not know exactly what you are talking about lets chat. ...Read more
E. coli strains: Most E. coli are normal bowel inhabitants. But some, particularly those with the serotype OH157, are capable of producing a shiga toxin that is similar to that produced by bowel pathogens. But DH5a is not one of these toxin-producing strains, and is more commonly used as a laboratory strain for studying expression of genetic characteristics following cloning experiments. ...Read more
Most well known type: 0157:h7 is the most common 'genetic strain' of disease producing shiga toxin producing E. coli in the US. It is most often introduced into individuals through contaminated food that is undercooked. It was also believed to be the most likely variant associated with severe illness, however the outbreak in Germany last year of severe STEC was from a different strain, known as 0104:h4. ...Read moreSee 1 more doctor answer
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
Bowel to bladder: Significant amount of stool consists of e. Coli bacteria, & thus skin in perineal area is not unusually colonisd by bowel e. Coli. There is very little disnance from anus to urethral opening in women, & women's urethras avery short, so it is very easy e. Coli bacteria to reach the bladder. Most women secrete vaginal immunoglobulins which can be bacteriocidal, & one reason why most women r UTI free. ...Read more
A total of 8 different organisms in my wound: e. Coli, acinetobacter baumannii, stenotrophomonas, are these hospital acquired infections?
Yes.: They can all be hospital acquired infections. ...Read more
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 moreSee 1 more doctor answer
