La prise en charge des animaux contagieux, ou suspects de l’être, suit des procédures définies et écrites adaptées à la structure vétérinaire. La première barrière à l’introduction d’un germe contagieux dans une structure de soins est une application quotidienne stricte quel que soit l’animal des mesures d’hygiène de base, que ce soit pour l’hygiène des mains, des locaux, des surfaces et du matériel. L’animal suspect ou confirmé contagieux est orienté dès son arrivé dans la structure, ou à défaut le plus tôt possible dès la détection du problème, vers le circuit pour animaux contagieux. La con

Resumen
Background: Mobile phones are increasingly associated with the transmission of pathogenic microbial agents. In the clinical setting where there is usually high exposure to pathogens, these devices may serve as vehicles for the transmission/spread of pathogens. This study determined the prevalence of bacterial contamination of mobile phones of health workers and the predisposing factors, in order to ascertain the risk of transmission of pathogenic bacteria through mobile phones.Methodology: This study was carried out in a private medical center at Mbouda, Cameroon, involving 78 health workers i

Chez les adolescents et jeunes adultes, ces espaces abritent des bactéries pathogènes parodontales.

Background: Hospital-acquired infections (HAIs) remain a common problem, which suggests that standard decontamination procedures are insufficient. Thus, new methods of decontamination are needed in hospitals. Methods: We assessed the effectiveness of a no-touch automated disinfection (NTD) system in the decontamination of 50 surfaces in 10 hospital rooms. Contamination of surfaces was assessed with a microbiological assay and an ATP bioluminescence assay. Unacceptable contamination was defined as > 100 colony forming units/100 cm2 in the microbiological assay, and as ≥ 250 relative light un

Bacteria, especially MDR isolates, can infect inanimate surfaces and equipment in ICUs (such as bedrails, stethoscopes, medical charts, and ultrasound machines). Transmission of microbes from inanimate surfaces may play a major role in the colonization and infection of patients in intensive care units. Healthcare worker hands and patient discharge both have the potential to spread germs, which can live for months on dry surfaces. It has been reported that the rate of environmental contamination is higher near infected individuals than it is near colonized patients, and that within the latter g

These interactions manifest themselves in the potential of mean force that the contaminant molecule experiences as it diffuses across the grafted polymer layer. For simplicity, we consider that all interactions are of the hard-sphere type. The size of the contaminant molecule is the

ABSTRACT Cross-contamination of raw food to other surfaces, hands, and foods is a serious issue in food service. With individuals eating more meals away from home, contracting a foodborne illness from a food service establishment is an increasing concern. However, most studies have concentrated on hands or food contact surfaces and neglected atypical and unusual surfaces (surfaces that are not typically identified as a source of cross-contamination) and venues. This review was conducted to identify atypically cross-contaminated surfaces and atypical venues where cross-contamination could occur

Resumen
In industrial sites, the movement and contact behaviors of workers are random, but their frequency and statistical characteristics can be determined. Particularly in machining workshops, metalworking fluids (MWFs) cause liquid oil contamination on the processed workpieces, and the contamination spreads to the entire workshop given the random contact of workers or the handling of workpieces. This study proposes a contact transmission model based on the Markov chain to quantify oil contamination transfer.

Despite the enormous interest in superhydrophobicity for self-cleaning, a clear picture of contaminant removal is missing, in particular, on a single-particle level. Here, we monitor the removal of individual contaminant particles on the micrometer scale by confocal microscopy. We correlate this space- and time-resolved information with measurements of the friction force. The balance of capillary and adhesion force between the drop and the contamination on the substrate determines the friction force of drops during self-cleaning. These friction forces are in the range of micro-Newtons. We show

Resumen
One steam-vacuuming unit (Unit A) was evaluated for removal of visible contamination and reduction of bacterial counts on beef carcass surfaces in five processing plants; a second steam-vacuuming unit (Unit B) was evaluated in two of those same plants at a later date. Experimental treatments included appropriate Controls: steam vacuuming carcass surfaces with or without visible contamination, and knife trimming surfaces with visible contamination. Depending on the processing plant, carcasses were tested on the midline or on the round. Each treatment was applied to a 103-cm2 area of the carcass

Resumen
High-k gate dielectrics and metal gate electrodes have become essential for emerging device technologies because they enable the continuous scaling down of devices while maintaining a high performance [. However, since they are composed of novel metallic elements that have never before been used in conventional processes, special care must be taken when handling these materials in the production line. In particular, cross-contamination that occurs due to transporting contamination via processed wafers can cause serious problems such as deterioration of device properties and yield loss [. The p

Resumen
This review surveys the problem of surface contamination of cars, which poses a growing engineering challenge to vehicle manufacturers, operators and users. Both the vision of drivers and the visibility of vehicles need to be maintained under a wide range of environmental conditions. This requires managing the flow of surface water on windscreens and side glazing. The rate of deposition of solid contaminants on glazing, lights, licence plates and external mirrors also needs to be minimised. Maintaining vehicle aesthetics and limiting the transfer of contaminants to the hands and clothes of use
