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 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

Whats e coli in urinary tract infection?

Whats e coli in urinary tract infection?

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

>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 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

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

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

 history of sinus infections +dx of UCTD. Recent sinus cultures positive atypical bacteria (Serratia marcescens +Stenotrophomonasmaltophilia - Why?

ID physician: S maltophilia is an organism of low virulence and frequently colonizes fluids used in the hospital setting and patient cultures. Serratia species are opportunistic gram-negative bacteria that are widespread in the environment. And something is definitely wrong here...unless your on say prednisone (for MCTD) and didn't mention this. You should see an infectious disease physician ASAP. ...Read more

History of renal stones. UTI this month (E. coli) took 3 courses of antibodies to clear. Day 2 off antibodies - my right kidney hurts. Concerned?

Pyelonephritis: Kidney stones may retain the microorganisms producing infection, making it very difficult to eradicate them without removing the stones. You may be having pain due to the stones producing obstructive symptoms or you may have recurrent infection in the kidney or other problems. Sounds like you should go back and see your doctor.

Under which circumstances will a "normal" E.Coli gain on its activity? Is a positive serum beta glucuronidase test related to such activity? TY.

Under which circumstances will a "normal" E.Coli gain on its activity? Is a positive serum beta glucuronidase test related to such activity? TY.

Hard to say/depends: This likely depends on what is considered "normal" about the E. coli and it's activity. E. coli is part of the normal "gut" flora. It's when certain other forms of E. coli like the O157:H7 strain get in the digestive tract that issues occur. So it's hard to say how activity would be affected unless abnormal E. coli get in there. The Bgluc test is homologous to the E. coli Bgalact enzyme. ...Read more

How do you get e-coli in your urine?

Travel up urethra: E. Coli species are the most common bowel bacteria and are invariably present on the perineal skin, no matter how well you wipe. They will be present in any urine temporarily trapped behind the labia and get "sucked" up the urethra during terminal muscle contractions at end of voiding. E. Coli around the urethral opening can be pushed up the urethra during sex. Hence advice to urinate after sex. ...Read more
