Most Common Bacteria That Cause Utis

Based on a study by The National Center for Biotechnology Information, the bacteria most commonly associated with causing UTIs are:

  • Escherichia coli
  • Pseudomonas aeruginosa
  • Enterococci

Based on the symptoms the patient is experiencing and before any testing is done to officially determine the infection type, the doctor prescribes first line antibiotics. For most UTIs, the prescribed antibiotic will cure the infection and not require any further testing.

Dosage For Skin Infections

ASK DIS: Urinary Tract Infection: Antibiotics in Adults

Adult dosage

Typical dosage is 500 mg every 12 hours, or 250 mg every 8 hours.

Child dosage

Typical dosage is 25 mg/kg/day in divided doses every 12 hours, or 20 mg/kg/day in divided doses every 8 hours.

The dosage listed here is meant for children who weigh less than 88 pounds . Children who weigh more than 88 pounds should be dosed according to the adult recommendations.

Child dosage

Maximum dosage is 30 mg/kg/day. Your childs doctor can tell you more about dosage.

Senior dosage

The kidneys of older adults may not work as well as they used to. This can cause your body to process drugs more slowly. As a result, more of a drug stays in your body for a longer time. This raises your risk of side effects.

Your doctor may start you on a lower dose or a different dosing schedule. This can help keep levels of this drug from building up too much in your body.

Dosage Regimens For Uti:

Currently, the duration of therapy for UTI is controversial. Although animals are routinely treated with antimicrobial drugs for 1014 days, shorter duration antimicrobial regimens are routinely prescribed in human patients, including single-dose fluoroquinolone therapy. A clinical comparison of 3 days of therapy with a once-daily high dose of enrofloxacin with 2 wk of twice daily amoxicillin-clavulanic acid showed equivalence in the treatment of simple UTI in dogs. However, further studies are needed to determine the optimal dosage regimens for different classes of antimicrobials, and it is inappropriate to use fluoroquinolones as first-line therapy for simple UTIs. Animals with complicated UTI may require longer courses of therapy, and underlying pathology must be addressed. Chronic complicated cases of UTI, pyelonephritis, and prostatitis may require antimicrobial treatment for 46 wk, with the risk of selecting for antimicrobial resistance. A follow-up urine culture should be performed after 47 days of therapy to determine efficacy. If the same or a different pathogen is seen, then an alternative therapy should be chosen and the culture repeated again after 47 days. Urine should also be cultured 710 days after completing antimicrobial therapy to determine whether the UTI has resolved or recurred.

What Oral Antibiotics Are Used To Treat An Uncomplicated Uti In Women

The following oral antibiotics are commonly used to treat most uncomplicated UTI infections :

Your doctor will choose your antibiotic based on your history, type of UTI, local resistance patterns, and cost considerations. First-line options are usually selected from nitrofurantoin, fosfomycin and sulfamethoxazole-trimethoprim. Amoxicillin/clavulanate and certain cephalosporins, for example cefpodoxime, cefdinir, or cefaclor may be appropriate options when first-line options cannot be used.

Length of treatment for cystitis can range from a single, one-time dose, to a course of medication over 5 to 7 days. Kidney infections may require injectable treatment, hospitalization, as well as a longer course of antibiotic, depending upon severity of the infection.

Sometimes a UTI can be self-limiting in women, meaning that the body can fight the infection without antibiotics however, most uncomplicated UTI cases can be treated quickly with a short course of oral antibiotics. Never use an antibiotic that has been prescribed for someone else.

In men with symptoms that do not suggest a complicated UTI, treatment can be the same as women. In men with complicated UTIs and/or symptoms of prostatitis are not present, men can be treated for 7 days with a fluoroquinolone . Tailor therapy once urine cultures are available.

Antibiotics Used For Complicated Utis

Before getting into how to best treat a complicated UTI, its important to understand which UTIs are considered complicated. Here are some guidelines:

  • Urinary tract abnormalities are present
  • Youre pregnant
  • The patient is a child
  • A comorbidity is present that increases risk of infection or treatment resistance, such as poorly controlled diabetes
  • Youre a man, since most UTIs in men are considered complicated
  • Youre elderly

Kidney infections are often treated as a complicated UTI as well, notes the Merck Manual.

If a UTI is complicated, a different course of antibiotics may be required. And the initial dose of antibiotics may be started intravenously in the hospital. After that, antibiotics are given orally at home. In addition, follow-up urine cultures are generally recommended within 10 to 14 days after treatment. Not all of the antibiotics approved for uncomplicated UTIs are appropriate for the complicated version. Some that are considered appropriate, include:

Use Of Antibiotics For Treating Utis In Dogs And Cats

JD Foster

VMD, DACVIM

Dr. Foster is an internist and Director of the Extracorporeal Therapies Service at Friendship Hospital for Animals in Washington, D.C. He has lectured around the world on various renal and urinary diseases and authored numerous manuscripts and book chapters on these topics. He is the current president of the American Society of Veterinary Nephrology and Urology.

Urinary tract infections are common in small animal practice it has been reported that up to 27% of dogs will develop infection at some time in their lives.1

Most UTIs are successfully treated with commonly used drugs, dosages, and administration intervals. However, infections can be challenging to effectively treat when they involve the kidneys and prostate . In addition, it can be difficult to create an appropriate antibiotic prescription in patients with kidney disease due to reduced drug clearance.

Understanding drug pharmacokinetics and pharmacodynamics is essential when determining the most effective antibiotic therapy. In addition, successful antimicrobial therapy requires appropriate choice of antibiotic, including dose, frequency, and duration .

Which Antibiotic Should Be Used To Treat A Uti

Treating a uti with ciprofloxacin. Reviews and ratings for cipro when ...

There are multiple types of antibiotics used to treat urinary tract infections . Different treatments may be recommended in different areas of the country based on regional patterns of antibiotic resistance.

Most patients with an uncomplicated UTI will begin treatment without any special diagnostic test, although a urinalysis may be performed by taking a urine sample. In a urinalysis, the chemical components of the urine are determined, and the doctor may look at urine color, clarity, and a view a sample under the microscope. A urine culture may be order, too, but is not always needed to start treatment. A urine culture can define the specific bacteria causing the UTI in more complicated cases or in the case of treatment failure.

Symptoms like burning and stinging while urinating will usually clear up in within one day after starting treatment. Be sure to finish your entire course of medication. If symptoms are still present after 2 to 3 days, contact your healthcare provider.

More extensive diagnostic procedures or imaging tests like an X-ray may be required if you continue to have frequent UTIs.

Population Health Research Capsule

What do we already know about this issue?

Previous studies have found overuse of antibiotics for urinary tract infections .

What was the research question?

To evaluate the appropriateness of antibiotic prescriptions for UTIs.

What was the major finding of the study?

Antibiotics were overused and inappropriate antibiotics were commonly prescribed for suspected UTIs.

How does this improve population health?

This study identified antibiotic misuse including overly broad antibiotics and overdiagnosis of UTIs, which can promote antimicrobial resistance.

Patients were categorized as having uncomplicated cystitis or pyelonephritis based on their ICD-10 code. In cases where the ICD-10 code CM N39.0 for urinary tract infection, site not specified was used, the authors categorized patients as having either cystitis or pyelonephritis based on medical chart documentation of symptoms, vital signs, physical exam, and provider impression. Patients were assigned to the pyelonephritis cohort if they had fever, flank pain, or costovertebral angle tenderness.

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.

If You Forget To Take It

If you forget to take a dose, take it as soon as you remember, unless it’s nearly time for your next dose. In this case, just leave out the missed dose and take your next dose at the usual time.

Never take 2 doses at the same time. Never take an extra dose to make up for a forgotten one.

If you forget doses often, it may help to set an alarm to remind you. You could also ask your pharmacist for advice on other ways to remember your medicines.

Urine Drug Concentration & Clinical Efficacy

How Effective Is Metronidazole for Urinary Tract Infection

Antimicrobial drugs must achieve an adequate urine concentration, which must be maintained for a sufficient time for a drug to be effective in treating UTI.16 It has been suggested that clinical efficacy is observed when the urine drug concentration is maintained at a concentration 4-fold higher than the isolates MIC throughout the time between doses.9

Experimental studies in rats have shown that the time for which the plasma drug concentration exceeds the isolates MIC correlates to the magnitude of bacterial colony count reduction the longer the time for which the drug concentration remained above the MIC, the lower the urine colony counts.12 Successful eradication of bacteria within the renal parenchyma or urinary bladder wall is correlated to the plasma, not urine, drug concentration.

When prescribing time-dependent antibiotics, shortening the interval between drug administration is the most effective method to allow the tissue/urine drug concentration to exceed the MIC for the majority of the dosing interval.

  • Drug elimination follows first-order kinetics, where 50% of the drug is lost in 1 half-life.
  • In contrast, doubling the dose would only add 1 half-life to the dosing interval.
  • To add 2 half-lives to the dosing interval, the initial dose would have to be increased 4-fold. The peak serum drug concentration achieved by this approach may exceed the window of safety, producing adverse drug effects.

Which Antibiotic Will Work Best

Your doctor will take a urine sample to confirm that you have a UTI. Then the lab will grow the germs in a dish for a couple of days to find out which type of bacteria you have. This is called a culture. Itâll tell your doctor what type of germs caused your infection. Theyâll likely prescribe one of the following antibiotics to treat it before the culture comes back:

Which medication and dose you get depends on whether your infection is complicated or uncomplicated.

âUncomplicatedâ means your urinary tract is normal. âComplicatedâ means you have a disease or problem with your urinary tract. You could have a narrowing of your ureters, which are the tubes that carry urine from your kidneys to your bladder, a narrowing in the urethra which transports urine from the bladder out of the body, or, you might have a blockage like a kidney stone or an enlarged prostate . Its also possible you have a urinary fistula or a bladder diverticulum.

To treat a complicated infection, your doctor might prescribe a higher dose of antibiotics. If your UTI is severe or the infection is in your kidneys, you might need to be treated in a hospital or doctors office with high-dose antibiotics you get through an IV.

Your doctor will also consider these factors when choosing an antibiotic:

  • Are you over age 65?
  • Are you allergic to any antibiotics?
  • Have you had any side effects from antibiotics in the past?
