“…The average MB found for the six objects assessed in the clinical environment during the preintervention phase was 28 times higher (6,985 CFU/100 cm 2 ; n ϭ 3,977 objects sampled) than levels commonly accepted as benign, Ͻ250 CFU/100 cm 2 ( Fig. 2) (11,18,19,23,40). The latter value was exceeded for each object sampled.…”

The contribution of environmental surface contamination with pathogenic organisms to the development of health care-associated infections (HAI) has not been well defined. The microbial burden (MB) associated with commonly touched surfaces in intensive care units (ICUs) was determined by sampling six objects in 16 rooms in ICUs in three hospitals over 43 months. At month 23, copper-alloy surfaces, with inherent antimicrobial properties, were installed onto six monitored objects in 8 of 16 rooms, and the effect that this application had on the intrinsic MB present on the six objects was assessed. Census continued in rooms with and without copper for an additional 21 months. In concert with routine infection control practices, the average MB found for the six objects assessed in the clinical environment during the preintervention phase was 28 times higher (6,985 CFU/ 100 cm 2 ; n ‫؍‬ 3,977 objects sampled) than levels proposed as benign immediately after terminal cleaning (<250 CFU/100 cm 2 ). During the intervention phase, the MB was found to be significantly lower for both the control and copper-surfaced objects. Copper was found to cause a significant (83%) reduction in the average MB found on the objects (465 CFU/100 cm 2 ; n ‫؍‬ 2714 objects) compared to the controls (2,674 CFU/100 cm 2 ; n ‫؍‬ 2,831 objects [P < 0.0001]). The introduction of copper surfaces to objects formerly covered with plastic, wood, stainless steel, and other materials found in the patient care environment significantly reduced the overall MB on a continuous basis, thereby providing a potentially safer environment for hospital patients, health care workers (HCWs), and visitors.

“…The responsibility for cleaning near-patient sites commonly and frequently touched by hands does not always rest with the ward cleaners, however, since beds, drip stands, lockers and over-the-bed tables are more commonly cleaned by nurses (13)(14) . Nurses are also responsible for the decontamination of more delicate clinical equipment.…”

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.

“…Authorities have said that the internationally recognized value of 5 CFU/cm 2 could be used as a starting point. However, it should be kept in mind that not all surfaces in a hospital are analogous with surfaces in the food industry (2,8).…”

A series of [(4-nitro-1 H -imidazol-1-yl)methyl]-1,2,4-triazoles and 1,3,4-thiadiazoles were prepared and evaluated for their activity against sensitive and resistant H. pylori strains. Study of the structure-activity relationship of these series of compounds indicated that the type of nitroimidazole moiety and the pendent group on the heteroaryl analog dramatically impact the anti-H. pylori activity. In triazole series, compound 5d, containing a 4-methyl phenyl group on the triazole ring, was the most potent compound tested against both metronidazole-sensitive and -resistant strains at a concentration of 8 μ g.
