Urinary Tract Infection Caused By E Coli

Must read

How Is A Uti Diagnosed

Urinary Tract Infection-E.Coli

To find out whether you have a UTI, your doctor or nurse will test a clean sample of your urine. This means you will first wipe your genital area with a special wipe. Then you will collect your urine in midstream in a cup. Your doctor or nurse may then test your urine for bacteria to see whether you have a UTI, which can take a few days.

If you have had a UTI before, your doctor may order more tests to rule out other problems. These tests may include:

  • A cystogram. This is a special type of x-ray of your urinary tract. These x-rays can show any problems, including swelling or kidney stones.
  • A cystoscopic exam. The cystoscope is a small tube the doctor puts into the urethra to see inside of the urethra and bladder for any problems.

How Can I Prevent Or Avoid An E Coli Infection

The most important thing you can do to protect against E. coli infection is to wash your hands frequently. Always wash your hands thoroughly before and after cooking and after handling raw meat or poultry.

Wash your hands after using the restroom, changing diapers or after contact with animals.

If youve been infected with E. coli, scrub your hands vigorously with soap and clean under your fingernails where bacteria can get caught. Dry your hands with paper towels instead of cloth towels to avoid transferring bacteria.

You can also reduce your risk of an E. coli infection by following these food preparation and cooking tips.

When thawing meats:

  • Dont defrost frozen meat unwrapped on the counter.
  • Keep frozen meat in a separate plastic bag when thawing.

When prepping foods:

  • Dont rinse meat before cooking. Its not necessary. Washing the meat could spread bacterial to nearby surfaces, utensils and other food.
  • Use a plastic or ceramic cutting board to cut raw meat. These materials can be cleaned more easily and thoroughly than wooden cutting boards.
  • Dont cross-contaminate a prepping surface. If you had raw meat or chicken on a prepping surface, such as a cutting board, wash it thoroughly with soap and hot water before putting another type of food on it. Better yet, use different cutting boards for the foods you are preparing.
  • Rinse all raw fruits and vegetables under cold running water before eating them. Its ok to scrub firm produce but dont use detergent or soap.

This Bacteria Is Behind The Vast Majority Of Utis


Urinary tract infections, or UTIs for short, are the most common type of bacterial infection diagnosed today. 01054-9/fulltext” rel=”nofollow”> 1) And the most common bacteria to cause these infections are Escherichia coli, aka E. coli. In fact, E. coli is responsible for more than 85 percent of all urinary tract infections, according to research published in March 2012 in the journal Emerging Infectious Diseases.

Worldwide, 150 million people are affected by UTIs each year, and about 10.5 million of those individuals are in the United States, according to research published in May 2015 in the journal Nature Reviews Microbiology. Women get urinary tract infections up to 30 times more often than men do, with up to 60 percent of women getting a UTI at least once in their lives.

Can Urinary Tract Infections Be Prevented Or Avoided

There are many lifestyle choices that can help you prevent UTIs. These are some of the things you can do to protect yourself from them:

  • Drink plenty of water to flush out bacteria. For some people, drinking cranberry juice may also help prevent urinary tract infections. However, if youre taking warfarin, check with your doctor before using cranberry juice to prevent urinary tract infections. Your doctor may need to adjust your warfarin dose or you may need to have more frequent blood tests.
  • Dont hold your urine. Urinate when you feel like you need to. Some children dont go to the bathroom often enough. If your child does this, teach him or her to go to the bathroom several times each day.
  • Wipe from front to back after bowel movements. Teach your child to wipe correctly.
  • Urinate after having sex to help wash away bacteria.
  • Use enough lubrication during sex. Try using a small amount of lubricant before sex if youre a little dry.
  • If you get urinary tract infections often, you may want to avoid using a diaphragm as a birth control method. Ask your doctor about other birth control choices.
  • Avoid taking or giving your child bubble baths.
  • Wear loose-fitting clothing , and dress your child in loose-fitting clothing.
  • If you are uncircumcised, wash the foreskin regularly. If you have an uncircumcised boy, teach him how to wash his foreskin.

Treatment Of Kidney Infection

E. coli and Urinary Tract Infections (UTIs)

Most kidney infections need prompt treatment with antibiotics to stop the infection damaging the kidneys or spreading to the bloodstream.

You may also need painkillers.

If you’re especially vulnerable to the effects of an infection , you may be admitted to hospital and treated with antibiotics through a drip.

Most people who are diagnosed and treated promptly with antibiotics feel completely better after about 2 weeks.

People who are older or have underlying conditions may take longer to recover.

Antimicrobial Susceptibility Pattern Of E Coli In Community

There are limited oral options for the treatment of ESBL-producing bacteria associated with lower urinary tract infections . Cotrimoxazole was a typical antibiotic used to treat UTIs, but the resistance of E. coli to this drug has markedly increased. According to the literature published in the past decade, in Asia, a 10~15% resistance rate to this drug was reported in Japan , with approximately 30% resistance rates observed in China and south Korea . In Europe and the Mediterranean region, the resistance rates of E. coli to cotrimoxazole varied but were usually over 15% . However, there was an interesting report wherein the authors emphasized the role of cotrimoxazole in empirical antibiotics because of the recent decrease in the resistance rate to cotrimoxazole in several European countries due to its low prescription rate . However, it may be not possible to reuse the drug worldwide within the next several years, and close observation of surveillance data will be required.

Does Cranberry Juice Prevent A Urinary Tract Infection

Many people say that cranberry juice can help treat, or even prevent, a UTI. Researchers are currently looking into the topic, but havent found a definitive answer yet. Healthcare providers recommend drinking lots of fluids if you have, or have a history of getting, a UTI. Adding a glass of unsweetened cranberry juice to your diet isnt a proven way to prevent a UTI, but it typically wont hurt you either.

Awareness Of Asymptomatic Bacteriuria

ABU should be distinguished from symptomatic UTI. ABU occurs in an estimated 1-5% of healthy pre-menopausal females, increasing to 4-19% in otherwise healthy elderly females and men, also occurring in 0.7-27% of patients with diabetes, 2-10% of pregnant women, 15-50% of institutionalized elderly patients, and 23-89% of patients with spinal cord injuries . ABU does not cause systemic influences, such as renal damage . Thus, treatment of ABU is not recommended in patients without risk factors . Furthermore, ABU should not be overtreated without the awareness of the physician . Even in catheterized patients , antibiotics should be considered only when patients with indwelling catheters present symptoms or they have any complications during placement or exchanges of catheters . In contrast, considering ABU in pregnancy, many researches recommended treating the UTIs because not to treat UTIs in pregnant women can increase the possibilities of preterm labor or low birth-weight .

Vaccines Targeting Bacterial Adhesion

Parenteral Diarrhea and Urinary Tract Infections

As adherence has a key role at nearly every step of UTI pathogenesis, one attractive strategy for the development of antivirulence therapies, including vaccines, has been to target CUP pili. As a general rule, vaccination with whole pili has been ineffective at generating an antibody response that can protect against UTIs. However, adhesin-based vaccines have been shown to be effective at blocking hostpathogen interactions, thus preventing the establishment of disease. Experiments using mouse and cynomolgus monkey models of UTIs determined that immunization with PapDPapG or FimCFimH chaperoneadhesin complexes protected against UTIs. The effectiveness of the FimCFimH vaccine was shown to be due, in large part, to antibodies that block the function of FimH in bladder colonization. Furthermore, the anti-FimH antibodies did not seem to alter the E. coli niche in the gut microbiota. Modifications of this vaccine are currently under development, with the aim of inducing greater immune stimulation,. For example, one approach has been to fuse FimH to the flagellin FliC in order to induce a more substantial acute inflammatory response, which functions through TLR4 signalling via the MYD88 pathway. A Phase I clinical trial began in January 2014 to evaluate the efficacy of a FimCFimH vaccine using a synthetic analogue of monophosphoryl lipid A as the adjuvant.

How Are Urinary Tract Infections Treated

You will need to treat a urinary tract infection. Antibiotics are medicines that kill bacteria and fight an infection. Antibiotics are typically used to treat urinary tract infections. Your healthcare provider will pick a drug that best treats the particular bacteria thats causing your infection. Some commonly used antibiotics can include:

  • Nitrofurantoin.
  • Doxycycline.
  • Quinolones .

Its very important that you follow your healthcare providers directions for taking the medicine. Dont stop taking the antibiotic because your symptoms go away and you start feeling better. If the infection is not treated completely with the full course of antibiotics, it can return.

If you have a history of frequent urinary tract infections, you may be given a prescription for antibiotics that you would take at the first onset of symptoms. Other patients may be given antibiotics to take every day, every other day, or after sexual intercourse to prevent the infection. Talk to your healthcare provider about the best treatment option for you if you have a history of frequent UTIs.

Antimicrobial Drugs And Uropathogenic Escherichia Coli

Managing UTI caused by UPEC has become challenging over the years due to increasing resistance to the commonly used antibiotics , which poses a great threat to future capacity to treat UTI caused by UPEC. Although TMP-SMX has traditionally been used as a first-line treatment for UTI , there are reports of increased resistance to this antibiotic, which in some countries is in the range 1520% . Many UPEC strains resistant to TMP-SMZ are also resistant to amoxicillin and cephalexin. Nitrofurantoin remains highly effective against UPEC, but is mainly used for cystitis treatment due to its inability to attain sufficient serum levels to treat invasive or systemic infections , and all have excellent bioavailability and achieve high urinary concentrations. However, increased FQ use has resulted in a rise in the prevalence of resistance, and FQ-resistant E. coli has become a major problem in several countries .

When Should I Call My Healthcare Provider

  • Fever.
  • Back pain.
  • Vomiting.

If you have any of these symptoms, or your other symptoms continue after treatment, call your healthcare provider. A UTI can spread throughout your urinary tract and into other parts of your body. However, treatment is very effective and can quickly relieve your symptoms.

Urinary Tract Infection: Signs, Causes And How You Can Prevent Them

Previous studies show that in E. coli isolates from patients with urosepsis, resistance to antimicrobial agents such as ampicillin, sulfonamides, tetracycline, chloramphenicol, and streptomycin is negatively associated with virulence and a phylogenetic group B2, but positively associated with host compromise . There is a similar negative association between FQ resistance and VFs and group B2 . This suggests that, resistance may provide a greater fitness advantage to E. coli than traditional VFs or a group B2 background, allowing them to cause infections in compromised hosts with weakened defenses who are frequently exposed to antibiotics.

Dna Extraction And Genome Sequencing

Liquid cultures of each strain were grown from freezer stock in LB at 37°C in a shaking incubator for 12 h. DNA was extracted from liquid culture using the Qiagen DNeasy UltraClean Microbial Kit following the manufacturers protocol. DNA concentration was quantified using the Qubit fluorometer. To confirm the MALDI-TOF classification, the 16S rRNA gene sequence was amplified using the 63f and 1387r primers and sequenced by Genewiz , using each primer individually for 2× coverage. The resulting sequences were manually trimmed and paired in Geneious v11.0.5 and queried against the NCBI 16S rRNA sequences database via blastn to confirm that they were E. coli. DNA libraries were constructed using the Nextera XT DNA Library preparation kit and sequenced on the Illumina MiSeq platform using the MiSeq Reagent Kit v2 at Loyola University Chicagos Genomics Facility . Raw sequencing reads were deposited in NCBIs SRA database.

Do I Need To See A Doctor

Yes. Painful urination can be a symptom of a more serious problem. You should tell your doctor about your symptoms and how long youve had them. Tell your doctor about any medical conditions you have, such as diabetes mellitus or AIDS, because these could affect your bodys response to infection. Tell your doctor about any known abnormality in your urinary tract, and if you are or might be pregnant. Tell your doctor if youve had any procedures or surgeries on your urinary tract. He or she also need to know if you were recently hospitalized or stayed in a nursing home.

If your doctor thinks your pain may be from vaginal inflammation, he or she may wipe the lining of your vagina with a swab to collect mucus. The mucus will be looked at under a microscope to see if it has yeast or other organisms. If your pain is from an infection in your urethra , your doctor may swab it to test for bacteria. If an infection cant be found, your doctor may suggest other tests.

And It Won’t Hurt To Try These

#411 Effect of Escherichia coli infection on lower urinary tract function in male patients

Like many women, you may have memorized the following age-old advice for preventing UTIs:

  • Wipe from front to back.

  • Urinate before and after sex.

  • Drink lots of water.

  • Avoid tight underpants and jeans.

These suggestions are directed at flushing the bladder and keeping E. coli from spreading into the urinary tract. Although studies have failed to show that they prevent either primary or recurrent UTIs, there’s no harm in trying them, Dr. Gupta says. “They can’t hurt, and if they help, you’re ahead of the game.”

Causes Of Kidney Infection

A kidney infection usually happens when bacteria, often a type called E. coli, get into the tube that carries urine out of your body .

The bacteria travel up to your bladder, causing cystitis, and then up into your kidneys.

E. coli bacteria normally live in your bowel, where they cause no harm.

They can be transferred from your bottom to your genitals during sex or if you’re not careful when wiping your bottom after going to the loo.

A kidney infection can sometimes develop without a bladder infection. For example, if you have a problem with your kidney, such as kidney stones, or if you have diabetes or a weakened immune system.

E Coli And Virulence Factors

Virulence refers to the ability of an organism to cause disease, and is a function of the presence of distinct accessory traits, referred to as virulence factors . VFs are specific properties that enable organisms to overcome host defenses and cause disease . However, although several VFs have been identified in UPEC, experimental and epidemiological data have shown that none uniquely defines these pathogens.

UPEC VFs are grouped by functional categories as adhesins, toxins, iron acquisition systems, and protectins. VFs are encoded by genes located on chromosomes or plasmids, with some being exclusively chromosomal (e.g., pap

Adhesins, which appear as hair-like fibers called fimbriae , facilitate the colonization with E. coli in the urinary tract by attaching to host epithelial cells. This attachment promotes the persistence of the organism in the bladder, and serves as a reservoir for ascending infection in the urinary tract .

Although most studies have confirmed that type 1 fimbriae are particularly important in bladder colonization , the proportions of UPEC strains from urine and feces expressing type 1 fimbriae appear to be similar , ranging from a high of 71% among isolates from cystitis patients to a low of 58% among those from patients with ASB, with fecal strains in the mid-range at 60% . However, in contrast, the level of expression of type 1 fimbriae among UPEC blood isolates is significantly different from that of fecal strains .

Try Taking A Probiotic

Introducing a probiotic to your system may help to replenish the naturally occurring, healthy bacteria that live in the gut. It is thought that probiotics may prevent harmful bacteria from attaching to the urinary tract cells, and may also lower the urine Ph, making it less hospitable to harmful bacteria. And, if you have taken an antibiotic to treat a UTI, taking a probiotic is a great way to build up the healthy bacteria that may have been killed during your course of treatment. Probiotics are found in supplement form , or they occur naturally in some types of food, including certain yogurts, kombucha, or kefir.
