“…The biocide triclosan, however, is extremely active against P. mirabilis. The MIC of this agent for P. mirabilis isolates from encrusted catheters was found to be 0.2 g/ml (173). In experiments in laboratory models supplied with artificial urine and infected with P. mirabilis, triclosan was shown to diffuse through the balloons of all-silicone catheters into the residual urine.…”

“…The strategy was also effective when artificial urine was replaced with pooled human urine and when latexbased catheters were tested. Triclosan was found to have impregnated the all-silicone catheters but not the latex-based devices (173). These experiments were all performed under conditions in which a catheter is introduced into residual urine that is heavily colonized by P. mirabilis (10 8 CFU/ml) and has a pH of above 8.0.…”

SUMMARY Catheter-associated urinary tract infections (CAUTIs) represent the most common type of nosocomial infection and are a major health concern due to the complications and frequent recurrence. These infections are often caused by Escherichia coli and Proteus mirabilis. Gram-negative bacterial species that cause CAUTIs express a number of virulence factors associated with adhesion, motility, biofilm formation, immunoavoidance, and nutrient acquisition as well as factors that cause damage to the host. These infections can be reduced by limiting catheter usage and ensuring that health care professionals correctly use closed-system Foley catheters. A number of novel approaches such as condom and suprapubic catheters, intermittent catheterization, new surfaces, catheters with antimicrobial agents, and probiotics have thus far met with limited success. While the diagnosis of symptomatic versus asymptomatic CAUTIs may be a contentious issue, it is generally agreed that once a catheterized patient is believed to have a symptomatic urinary tract infection, the catheter is removed if possible due to the high rate of relapse. Research focusing on the pathogenesis of CAUTIs will lead to a better understanding of the disease process and will subsequently lead to the development of new diagnosis, prevention, and treatment options.

“…The authors examined catheter-associated urinary tract infections (CAUTI) caused by uropathogenic Escherichia coli. This is one of the most common device-related infections, which can give rise to serious medical complications [79]. Their interest was in exploring the effects the surface microstructures of the Sharklet design had on bacterial colonization and migration.…”

Nano and Microscale Topographies for the Prevention of Bacterial Surface Fouling

Bacterial surface fouling is problematic for a wide range of applications and industries, including, but not limited to medical devices (implants, replacement joints, stents, pacemakers), municipal infrastructure (pipes, wastewater treatment), food production (food processing surfaces, processing equipment), and transportation (ship hulls, aircraft fuel tanks). One method to combat bacterial biofouling is to modify the topographical structure of the surface in question, thereby limiting the ability of individual cells to attach to the surface, colonize, and form biofilms. Multiple research groups have demonstrated that micro and nanoscale topographies significantly reduce bacterial biofouling, for both individual cells and bacterial biofilms. Antifouling strategies that utilize engineered topographical surface features with well-defined dimensions and shapes have demonstrated a greater degree of controllable inhibition over initial cell attachment, in comparison to undefined, texturized, or porous surfaces. This review article will explore the various approaches and techniques used by researches, including work from our own group, and the underlying physical properties of these highly structured, engineered micro/nanoscale topographies that significantly impact bacterial surface attachment.

“…Todos os tipos de cateter de Foley disponíveis são vulneráveis à incrustação, o que compromete a drenagem urinária e o resultado é a dor com sofrimento do paciente e necessidade de remoção do cateter (Gorman et al, 2003). Ainda não existem métodos disponíveis para o controle efetivo do problema (Jones et al, 2005b). Devido à importância da incrustação no desempenho dos cateteres urinários, este assunto vem sendo estudado por Barford et al (2008), Bettio et al (2008a, b), Camargo et al (2005a, b), Jones et al (2005a, b), Lawrence e Turner (2005), Mathur et al (2006), Pizzolitto et al (2002), Santos e Pizzolitto (2007, 2008, Santos et al (2008a, b, c), Shaw et al (2005), , Stickler et al (1993), Stickler e Morgan (2008) e Tunney et al (1997).…”
