Epithelial cells/mixed growth: mixed growth may indicate perineal contamination; however a small proportion of UTIs may be due to genuine mixed infection. Reassessment of Routine Midstream Culture in Diagnosis of Urinary Tract Infection. What information is needed to assist with UTI determination? No. Copyright 1999 by the American Academy of Family Physicians.

Up to one third of uropathogens are resistant to ampicillin and sulfonamides, but the majority are susceptible to trimethoprim-sulfamethoxazole (85 to 95 percent) and fluoroquinolones (95 percent).3,11, In view of the limited spectrum of causative organisms and their predictable susceptibility, urine cultures and susceptibility testing add little to the choice of antibiotic for the treatment of acute uncomplicated cystitis in young women. Leukocytes in urine. Educational text answers on HealthTap are not intended for individual diagnosis, treatment or prescription. What do these results mean? Asymptomatic bacteriuria is defined as the presence of more than 100,000 CFU per mL of voided urine in persons with no symptoms of urinary tract infection.

If pyuria (> 40 WBC) is present, and the specimen culture suggests contamination, a repeat sample is advisable, if clinically indicated. The most common bacteria found in the urethra and bladder are Escherichia coli, which is found in about 60% of healthy people. Unfortunately, some clinical laboratories do not report counts of less than 10,000 CFU per mL of urine. 0 CDC twenty four seven.

Of course, there may be certain clinical situations in which it could be appropriate to evaluate in more detail a mixed culture or a culture with an organism that isnt usually a uropathogen (for example, if a patient has indwelling urinary tract hardware), so, as always, clinicians can call the microbiology lab to ask for more detail about exactly what grew on a particular plate or to request that additional workup be performed in specific cases.

These infections are generally not associated with underlying anatomic abnormalities and do not require further work-up of the genitourinary tract.5,11,18. Since E. coli resistance to ampicillin, amoxicillin and first-generation cephalosporins exceeds 30 percent in most locales, these agents should not be used empirically for the treatment of pyelonephritis.11 Even though trimethoprim-sulfamethoxazole is often considered the treatment of choice, resistance to this drug combination may exceed 15 percent in some regions. Q10: If a patient has a history of urinary urgency, urinary frequency or dysuria can another recognized cause be determined?
