Small Compounds Targeting Urease
Urease, an enzyme which catalyzes the hydrolysis of urea, is crucial in the pathogenesis of several uropathogenic bacteria such as P. mirabilis, Klebsiella sp., Pseudomonas sp. and Staphylococcus sp. . This enzyme leads to the alkalinization of the urine and the production of struvite and carbonate apatite that make up the major component of urinary stones . These conditions lead to the inflammation of the urogenital epithelia thus increasing the risk of catheter-associated biofilm formation that may contribute to pyelonephritis , mainly due to both bacterial and host cysteine protease .
The most studied inhibitors of urease are hydroxamic acids . These molecules have a high inhibitory activity against urease, by bonding to the two nickel ions in the urease active site . Initially, these molecules were used to treat UTIs by preventing urine alkalization . However, because of the growing evidence of side effects such as mutagenic power, they were progressively phased out .
Through similarly interacting with nickel ions in the urease active site, the phenyl phosphoramidates were found to have the highest inhibitory activity . Studies testing these molecules in an in vitro model and in a rat model found promising results. Since then, no in vivo studies or clinical trials have been developed, probably due to the poor hydrolytic stability of these molecules which leads to a very short half-life .
Treatments For Specific Populations
Treating Pregnant Women
Pregnant women should be screened for UTIs, since they are at high risk for UTIs and their complications. Antibiotics used for treating pregnant women with UTIs include amoxicillin, ampicillin, nitrofurantoin, and cephalosporins . Fosfomycin is not as effective as other antibiotics but is sometimes prescribed for pregnant women. In general, there is no consensus on which antibiotic is best for pregnant women although some types of antibiotics, such as fluoroquinolones and tetracyclines, should not be taken as they can cause harm to the fetus.
Pregnant women with asymptomatic bacteriuria have an increased risk for acute pyelonephritis in their second or third trimester. They need screening and treatment for this condition. In such cases, they should be treated with a short course of antibiotics . For an uncomplicated UTI, pregnant women may need longer-term antibiotics .
Treating Children with UTIs
Children with UTIs are generally treated with TMP-SMX, cephalexin and other cephalosporins, or amoxicillin/clavulanic acid . These drugs are usually taken by mouth in either liquid or pill form. Doctors sometimes give them as a shot or IV. Children usually respond to treatment within a few days. Prompt treatment with antibiotics may help prevent renal scarring.
Children with acute kidney infection are treated with various antibiotics including oral cefixime or a short course of an intravenous antibiotic . An oral antibiotic then follows the IV.
E Coli In Urine Culture What Does It Mean
When your lab assistant tells you that they have found E. coli in urine, it usually means you have a urinary tract infection and your doctor may ask for other tests to confirm what type of infection it is. Under normal circumstances, your urine in the bladder contains no bacteria or other organisms, but that’s not the case when bacteria enter your urine through the urethra. Escherichia coli or E. Coli is among the most common causative agents of UTIs. Your doctor will confirm the presence of these bacteria in your urine through a urine culture test, but they will also look for the presence of any red blood cells, while blood cells, or bacteria.
Your lab assistant may ask you to wipe clean your genital area before the test to avoid any contamination. They will then analyze your urine and if they find something specific, they will proceed with a urine culture test to confirm an infection. This test will help confirm the types of bacteria causing infection in your case this will also help identify the best medicine for the infection.

Ecoli Uti Infections In Urine
As its name suggests, urinary tract infection or UTI is an infection of the kidneys, bladder, ureters, or urethra. Escherichia coli or E. coli is responsible for more than 85 percent of all UTIs, according to a 2012 report in the journal Emerging Infectious. Urinary tract infections arent usually serious, but they can be dangerous if the bacteria make their way into the kidneys. Left untreated, a kidney infection can cause permanent kidney damage and even deadly blood poisoning. Urinary tract infections can have different names referring to the different parts of the urinary tract
- Bladder infection = Cystitis
- Kidney infection = pyelonephritis

Preventing Urinary Tract Infections
There are numerous ways in which one can help prevent UTIs from occurring. Some at-home measures include:
- Urinate frequently. Emptying the bladder roughly every two to three hours will help to flush the E. coli bacteria from the urinary tract before an infection can begin.
- Wipe from front to back. This helps prevent spreading bacteria from the anal area to the urethra.
- Urinate after intercourse. Sexual intercourse and contact can introduce bacteria from the anus into the bladder by way of the urethra. But urinating after sex helps to flush bacteria from your system.
- Consume plenty of liquids. Drinking water helps dilute urine and spur more frequent urination, which flushes E. coli from the urinary tract.
- Avoid diaphragms or spermicides. These can contribute to bacterial growth and kill the good bacteria that work to protects against UTIs.
How To Wash Hands To Avoid Infection
While opting for a hand sanitizer may seem like a smart choice when no running water is close by, know that the U.S. Food and Drug Administration has not approved any products claiming to prevent E. coli infection.
Its also very important to follow certain food preparation and cooking rules. Here is what the Centers for Disease Control and Prevention urges people to do:
- Wash produce. Wash well under running water. Be sure to open up leafy greens, since E. coli can hide in the crevices.
- Cook beef thoroughly. Cook to an internal temperature of at least 145 degrees F for beef steak and roasts and at least 160 degrees F for ground beef and pork.
- Avoid cross-contamination. Use separate cutting boards for meats and produce, and clean counters and utensils after contact with raw meat.
Finally, do not consume any unpasteurized dairy products, unpasteurized juices, or raw milk. And avoid swallowing water when swimming in lakes, ponds, streams, swimming pools, and even backyard kiddie pools.

Antibiotic Treatment Of Utis By Mdr Gram
In regard to laboratory cut-off values of microbial load , it is very difficult to determine treatment initiation in certain cut-off value. However, bacterial count is usually 102 ~ 104 cfu/ml in many patients with UTIs, and half of women with symptomatic cystitis have bacteriuria lower than 105 cfu/ml . Franz et al. also suggested antibiotic treatment in symptomatic patients with microbial load between 102 and 105 cfu/ml . Furthermore, when severe infection such as urinary sepsis was suspected, physicians should start antibiotic therapy before the cultivation report because of its high mortality. Therefore, symptoms may be more important factor than the cut-off values of laboratory microbial load to initiate the treatment of UTIs.
Clinical studies have indicated that delayed treatment with inappropriate antibiotics for MDR bacteremia would exert a negative influence on patient mortality . Therefore, when a MDR bacterial infection is suspected and previous cultivation reports are not available, or when a patient has a systemic illness, physicians may be obligated to choose parenteral agents such as piperacillin/tazobactam or carbapenems empirically. In these circumstances, patients require hospitalization.
Researchers Use Antibiotics Combo To Kill First Strain Of Highly Resistant E Coli In Us

The golden age of antibiotics may be drawing to a close. The recent discovery of E. coli carrying mcr-1 and ndm-5 genes that make the bacterium immune to last-resort antibiotics has left clinicians without an effective means of treatment for the superbug. But in a new study, University at Buffalo researchers have assembled a team of three antibiotics that, together, are capable of eradicating the deadly bacterium. The groundbreaking research was recently published in mBio, a journal for the American Society of Microbiology.
The researchers found that a novel combination of aztreonam, amikacin and polymyxin B a last-resort antibiotic was able to kill E. coli carrying mcr-1 and ndm-5 genes within 24 hours while also preventing regrowth. Traditional combinations of these antibiotics were unable to kill the E. coli and resulted in rapid resistance.
This is the first study to propose therapeutic solutions with three drugs against superbugs harboring mcr-1 and ndm-5. The results will help prepare clinicians for future occurrences of these pathogens.
To avoid prescribing high dosages of polymyxins and to make up for the antibiotics weaknesses, the researchers decided to turn to new dosing strategies and multiple antibiotic combinations.

Specific Risk Factors In Children
UTIs are rare during infancy but they are much more common in boys than in girls. Boys who are circumcised are far less likely than uncircumcised boys to develop UTIs by the time they are 1 year old. After the age of 2 years, UTIs are more common in girls. As with adults, E. coli is the most common cause of UTIs in children.
Vesicoureteral Reflux
Vesicoureteral reflux is the cause of up to half of the UTIs that occur during childhood. VUR also puts children at risk for UTI recurrence.
VUR is a condition in which the urine backs up into the kidneys. Normally, urine travels from the kidneys through the ureters, and into the bladder. When the bladder becomes filled, the muscle in the bladder wall contracts, and the urine leaves the body through another tube called the urethra. There is a valve-like mechanism at the point where the ureters join the bladder at an angle, through a tunnel under the mucosal lining. The job of these valves is to keep urine from flowing backward towards the kidneys when the bladder contracts. If the ureters enter the bladder through a shorter tunnel then these valves do not work well and urine may remain in the bladder where bacteria can grow. The backflow of urine may also carry any infection from the bladder up into the kidneys.

How Is The Infection Spread
It is difficult to spread a UTI between individuals, as the type of bacteria causing the infection is almost never contagious.
The most common way that a UTI is contracted is through the movement of bacteria from the anus to the urethra, either when wiping after going to the toilet or during sexual intercourse. Taking care during each of these activities can help to prevent the transfer of bacteria, which may then have the opportunity to overgrow.
Vigorous sexual intercourse may also lead to symptoms of UTI or cystitis in women , although there may be no bacteria present.

How Do Utis Affect Pregnancy
Changes in hormone levels during pregnancy raise your risk for UTIs. UTIs during pregnancy are more likely to spread to the kidneys.
If you’re pregnant and have symptoms of a UTI, see your doctor or nurse right away. Your doctor will give you an antibiotic that is safe to take during pregnancy.
If left untreated, UTIs could lead to kidney infections and problems during pregnancy, including:
- Premature birth
- Low birth weight
How Does E Coli Enter The Urinary Tract
E. coli naturally resides in the intestines of all humans, usually doing no harm. But some E. coli are pathogenic, meaning they can cause illness. With UTIs, the E. coli bacteria from the intestines is present in fecal matter. And trace amounts of said fecal matter make their way into the urinary tract through the urethra opening and begin to multiply, according to an article published in June 2012 in the journal Expert Review of Vaccines.
One of the reasons that women are more prone to urinary tract infections is that they have very short urethras. The E. coli bacteria from the rectum does not have a long distance to travel to reach the urethra and then bladder to cause an infection.
Some common ways in which this migration or infection can happen include:
- Sexual Contact A womans urethra is located next to the vagina and anus. This design makes it very easy for bacteria to move into the urinary tract during sexual intercourse and sexual contact.
- Improper Wiping For women, wiping from back to front after a bowel movement can drag E. coli directly into the urethra. Because of this, its always recommended to wipe from front to back.
- Holding Urine Frequent bathroom use allows the body to continue to flush bacteria such as E. coli from the system. This is especially important before and after intercourse. To encourage frequent urination, drink plenty of water throughout the day.
In addition, there are other factors that elevate your risk of developing a UTI. These include:

Discover How Using Cranberry Pills For Kidney Stones Can Keep Your Urinary System In Great Shape
Substantive research shows taking cranberry pills for kidney stones can help in alleviating this debilitating and painful condition. Scientists believe that the active ingredients in these capsules are great for preventing and staving off urinary tract infections since it prevents the solidification of urine to form kidney stones. In effect, it has the opposite effect that typically culminates in the formation of kidney stones by stopping the deposition of oxalates.
Treatment For Uncomplicated Utis
UTIs can often be successfully treated with antibiotics prescribed over the phone. In such cases, a health professional provides the people with 3 to 5-day antibiotic regimens without requiring an office urine test. This course is recommended only for women who have typical symptoms of cystitis, who are at low risk for recurrent infection, and who do not have symptoms suggesting other problems. It is always best to have a urine culture done before starting antibiotics when possible.
Antibiotic Regimen
Oral antibiotic treatment cures nearly all uncomplicated UTIs, although the rate of recurrence remains high. To prescribe the best treatment, the doctor should be made aware of any drug allergies of the person.
The following antibiotics are commonly used for uncomplicated UTIs:
After an appropriate course of antibiotic treatment, most people are free of infection. If the symptoms do not clear up within the first few days of therapy, doctors may suggest an alternate course of antibiotics. This may depend on the result of the urine culture. A urine culture may be ordered in order to identify the specific organism causing the condition if not done prior to starting antibiotics.
It should be noted that resistance to many of the commonly used antibiotics is growing and this is why it is now recommended to culture the urine before starting antibiotics. This helps reduce the overuse of these medications.
