YLaboratory based Rationale of the project: (Max 500 words)Relevance The project topic is relevant in that technology has modernized laboratory techniques and has led to adoption of touch screen devices. Touch screen devices have been extensively been used as the modern form of technology, there ease of use and accessibility are making it part and parcel of human life The usability of the touch screen devices in labs are linked to microbial contamination.. With the benefits linked to benefits of touch screens in lab simulations, results process analysis in labs and personal use, health hazards have been posed from this usage. In medical laboratory, touch screens are constantly being used for practical process, data recording and analysis. During laboratory sessions, touch screen devices are often touched and find themselves in cross contact with contaminated cultures thus getting contaminated with various microorganisms which have been found to be pathogenic and harmful to humans beings and even causing drug resistance effect. Methycline drug resistance has been found on Styphylococcus aureus andEnterococci, which is resistant to Vancomycin, (Gerba et l, 2016). 1
Drug resistance is detrimental to human health as it leads to disease resistance, which renders medication non effective thus creating resistant microorganism. The micro-organism could be fatal to human health and lead to death. Thus this portrays touch devices as possible reservoirs of micro organisms which could have potential significance among users. Literature ReviewStudies done on microbial contamination have shown that there are prevalence group of microbes which are present in lab compared to others. In a study conducted among laboratory practitioners in Pharos University Egypt, found out that most prevalent isolates of bacterial were staphylococci, (33%) andStyphyloccoci (24%)being present in mobile based devices, (Hadir, 2017). Further in a study done by Jaya et al, (2015) on bacterial contamination on mobile phones and computer devices found out that in samples of mobiles phones, screens, keypads and mice devices, touch pads were significantly contaminated with Gram positive bacteria. A comparative study assessing risks associated with microbial contamination of keypads and touch screen phones, showed that the microbial colony of touch screens and key pads was 0.09 (colony forming units) cfu/cm2and 0.77 cfu/cm2. This showed that colony counts were higher in key pad devicesat F statistic at p<0.001. Key pad devices were heavily contaminated with microbes, (Pal et al, 2013). In a study done among Italian University students, rated emissions of smart phones on tolerability of microbial survival and exposed at different time intervals, showed a reduction of 79% in bacterial growth in staphylococcus and 46% in staphylococcus epidermidis, thus showing that emissions are effective in reducing microbial growth, (Lodovico et al, 2018).Thus this studies show extensive research on microbial load and virulence in laboratory environments. Research gaps establishedFindings from the studies undertaken show that, none have focussed on the level of knowledge and awareness of microbial contamination of touch screens in laboratory environments. The users of the touch screen devices play acrucial role in the continuum process of microbial contaminations in laboratory. 2
