What is the best treatment for gram negative bacteria?
Oral therapy with an empirically chosen antibiotic that is effective against gram-negative aerobic coliform bacteria, such as Escherichia coli, is the principal treatment intervention in patients with lower urinary tract infections.
What is a UTI?
Urinary tract infections (UTIs) are common, recurrent infections that can be mild to life-threatening. The continued emergence of antibiotic resistance, together with our increasing understanding of the detrimental effects conferred by broad-spectrum antibiotic use on the health of the beneficial microbiota of the host, has underscored the weaknesses in our current treatment paradigm for UTIs. In this Review, we discuss how recent microbiological, structural, genetic and immunological studies have expanded our understanding of host-pathogen interactions during urinary tract pathogenesis. These basic scientific findings have the potential to shift the strategy for UTI treatment away from broad-spectrum antibiotics targeting conserved aspects of bacterial replication towards pathogen-specific antibiotic-sparing therapeutics that target core determinants of bacterial virulence at the host-pathogen interface.
What percentage of antibiotics are written for UTI?
Given that 9% of all antibiotic prescriptions in the ambulatory setting in the United States are written for the treatment of UTI, UTIs are at the forefront of the antibiotic resistance problem 139. Thus, there is an urgent need to develop antibiotic-sparing therapeutics for the treatment of UTI.
What causes UTIs in catheterized patients?
Although short-term community- and catheter-associated UTIs are mostly caused by monomicrobial infections, most CAUTIs in patients catheterized for long periods (>30 days) are polymicrobial in nature 132, 133. p. mirabilis, a Gram-negative bacterium that is nearly ubiquitous in soil and water, is a common constituent of CAUTI polymicrobial communities in chronically catheterized patients 133, 134. p. mirabilis uses various canonical virulence factors to establish infection in the bladder, including flagella and adhesive mannose-resistant Proteus-like MR/P fimbriae 135 ( Fig 3 ). In addition, P. mirabilis expresses high levels of urease, an enzyme that can hydrolyze urea to ammonia and raise the pH of urine to facilitate the formation of kidney stones 135. Although carriage of this enzyme is not uncommon in uropathogens, P. mirabilis urease activity generates a substantially higher urinary pH than any of its uropathogenic counterparts, enabling the formation of crystalline biofilms that provide a protective niche during antibiotic treatment, promoting recurrence 136. Recent work has revealed that, like UPEC, P. mirabilis invades the superficial umbrella cells of the bladder and forms IBCs in the urothelium 137.
What causes urinary tract infections?
Urinary tract infections (UTIs) are common infections caused predominantly by uropathogenic Escherichia coli (UPEC), which cause approximately 80% of UTIs. The annual incidence of physician-diagnosed UTIs in the United States is greater than 10% for females and 3% for males, and more than 60% of females will be diagnosed with a UTI in their lifetime 1, 2. Individual risk for infection depends on various factors, including age, sexual activity, family history, medical comorbidities and an individual history of UTI ( Box 1) 3. Recurrent UTIs (rUTIs; defined as three or more UTIs during a 12 month period 4) contribute greatly to the incidence and morbidity rates of UTI, as more than 30% of women will suffer from a subsequent infection within 12 months of resolution of initial symptoms despite appropriate antibiotic therapy 5. UTIs are becoming increasingly difficulty to treat owing to the rapid spread of drug resistance among Gram-negative organisms, including UPEC 6.
What bacteria are responsible for nosocomial cauti?
Enteroccocus faecalis and E. faecium are Gram-positive bacteria responsible for up to 17% of nosocomial CAUTIs 110, 113. Over 85% of E. faecium and 7% of E. faecalis clinical CAUTI isolates tested were found to be resistant to vancomycin 113. Using a mouse foreign-body implantation model of UTI ( Supplementary figure S1 ), it was found that Enterococci utilize endocarditis- and biofilm-associated pili (Ebp) to form biofilms on catheters and overcome the neutrophil-mediated immune response 119 ( Fig 3 ). Ebp pili are tipped with a fibrinogen-binding adhesin known as EbpA, which binds to the fibrinogen coating the catheter. Mutation of the N-terminal metal-ion-dependent fibrinogen-binding domain of the EbpA adhesin, or blockade with antibodies raised against the N-terminal domain of EbpA, prevents bacterial adhesion to fibrinogen-coated catheters in vitro and in mouse models of infection 120. Enterococci also use fibrinogen as a nutrient source, enabling their growth in urine 120. Enterococcal virulence is dependent on two secreted proteases, GelE and SprE, which are upregulated during infection to cleave the α-, β- and γ-chains of fibrinogen to potentiate biofilm formation ( Fig 3) 122. This provides further evidence that Enterococcus species utilize fibrinogen as both a binding platform and food source during biofilm formation and growth. Activation of SprE by host proteases was further shown to promote bacterial dissemination in the kidneys, whereas inhibition of either host or bacterial proteases was able to curb bacterial dissemination 120. Ebp pili are also important for cell-cell aggregation and interspecies gene transfer, facilitating the spread of genetic elements that encode antibiotic resistance and other virulence factors 123.
What is the ultimate reservoir for UPEC?
The gastrointestinal tract is the ultimate reservoir for UPEC, and FimH and has been shown to have a critical role in maintaining colonization of this habitat in mice. Depletion of this reservoir within a given host would be expected to reduce the rate of recurrent UTIs.
What is the role of P pili in pyelonephritis?
P pili bind globosides in the kidney and are essential for progression to pyelonephritis. Biophysical studies performed on type 1 pili revealed the importance of conformational dynamics in the adhesin and pilus rod during infection (right panel).
