“…Numerous epidemiological studies have shown that the most common bacteria causing hospital infections are Pseudomonas aeruginosa, Staphylococcus aureus, Enterococci and Escherichia coli [4][5][6][7]. Multi-resistant bacteria such as methicillin-resistant Staphylococcus aureus (MRSA) [8] or vancomycin-resistant Enterococci (VRE) [9] are of great concern in hospital environments and continue to challenge infection control and epidemiology practice worldwide.…”

Abstract:In the present work a detailed study of new bacteriostatic copolymers with quaternized ammonium groups introduced in the polymer chain through covalent attachment or electrostatic interaction, was performed. Different copolymers have been considered since beside the active species, the hydrophobic/hydrophilic nature of the co-monomer was also evaluated in the case of covalently attached bacteriostatic groups, aiming at achieving permanent antibacterial activity. Homopolymers with quaternized ammonium/phosphonium groups were also tested for comparison reasons. The antimicrobial activity of the synthesized polymers after 3 and 24 h of exposure at 4 and 22˝C was investigated on cultures of Gram-negative (P. aeruginosa, E. coli) and Gram-positive (S. aureus, E. faecalis) bacteria. It was found that the combination of the hydrophilic monomer acrylic acid (AA), at low contents, with the covalently attached bacteriostatic group vinyl benzyl dimethylhexadecylammonium chloride (VBCHAM) in the copolymer P(AA-co-VBCHAM88), resulted in a high bacteriostatic activity against P. aeruginosa and E. faecalis (6 log reduction in certain cases). Moreover, the combination of covalently attached VBCHAM units with electrostatically bound cetyltrimethylammonium 4-styrene sulfonate (SSAmC 16 ) units in the P(SSAmC 16 -co-VBCHAMx) copolymers led to efficient antimicrobial materials, especially against Gram-positive bacteria, where a log reduction between 4.9 and 6.2 was verified. These materials remain remarkably efficient even when they are incorporated in polysulfone membranes.

“…Nurses are also responsible for the decontamination of more delicate clinical equipment. This overlapping of cleaning responsibilities has created some confusion; it has also meant that cleaning opportunities for some items are missed or abandoned (15) .…”

Surface cleaning is a well-known control procedure against the dissemination of microorganisms in the hospital environment. This prospective study, carried out in an intensive care unit over the course of 14 days, describes the cleaning/disinfection conditions of four surfaces near patients. In total, 100 assessments of the surfaces were carried out after they were cleaned. Three methods were used to evaluate cleanliness: a visual inspection, an adenosine triphosphate (ATP) bioluminescence assay and testing for the presence of A inspeção visual não se mostrou medida confiável para avaliar a limpeza das superfícies.Os resultados demonstram que a rotina de limpeza adotada precisa ser revista. no se mostró una medida confiable para evaluar la limpieza de las superficies. Los resultados demostraron que la actual rutina de limpieza precisa ser modificada.

“…Methicillin-resistant Staphylococcus aureus (MRSA) has emerged as a significant nosocomial infectious threat, prompting several studies that have identified MRSA reservoirs in the hospital setting including bed rails, countertops, floors, bed linens, tables and blood pressure cuffs (Boyce et al, 1997;Blythe et al, 1998). Because of frequent dermal contact by numerous users, one reservoir of interest is computer keyboards, which have been shown to harbor MRSA in the hospital setting (Bures et al, 2000;Devine et al, 2001;Neely et al, 2005;Wilson et al, 2006).…”

Public computer surfaces are reservoirs for methicillin-resistant staphylococci

2007

The role of computer keyboards used by students of a metropolitan university as reservoirs of antibiotic-resistant staphylococci was determined. Putative methicillin (oxacillin)-resistant staphylococci isolates were identified from keyboard swabs following a combination of biochemical and genetic analyses. Of 24 keyboards surveyed, 17 were contaminated with staphylococci that grew in the presence of oxacillin (2 mg l À1 ). Methicillin (oxacillin)-resistant Staphylococcus aureus (MRSA), -S. epidermidis (MRSE) and -S. hominis (MRSH) were present on two, five and two keyboards, respectively, while all three staphylococci co-contaminated one keyboard. Furthermore, these were found to be part of a greater community of oxacillin-resistant bacteria. Combined with the broad user base common to public computers, the presence of antibiotic-resistant staphylococci on keyboard surfaces might impact the transmission and prevalence of pathogens throughout the community.
