There was no significant difference in the contamination of mobile phones between male and female clinicians (76.2 % vs. 68.1 %, respectively p-value = 0.276).
When the radiology and order computers were grouped together into the "clinical use" category, there was no significant difference in the contamination rate between accounting (10/47) and "clinical use" (39/235) computers (p = 0. 439).
Of the samples collected from the AERs reprocess to the gastroscope and colonoscope, 2.0% (6/300) and 0.8% (1/120), respectively, were found to be culture-positive and there was no significant difference in the contamination rate between the AERs reprocess to the upper and lower GI tract (p > 0.05).
To evaluate differences in the bacterial contamination rates of the vitreous cavity between patients undergoing transconjunctival 25-gauge microincision vitrectomy surgery (MIVS) and conventional 20-gauge pars plana vitrectomy (PPV).
It must be noted, however, that there are large differences in the average contamination between individual countries, and it is not always evident in the various studies whether or not drinking water was included in the calculations.
These discrepancies might be related to the use of different microarray platforms with different normalisation methods and differences in the degree of contamination by non-neoplastic cells in specimens, or heterogeneity in the patient population undergoing study (Konstantinopoulos et al, 2008).
However, only multivariate data from community analysis detected differences in the gradient of contamination.
We observed significant differences in the extent of contamination depending on the extraction method used, which might reflect the efficacy of the different techniques to remove DNA.
In our previous study the differences in contamination between the sites were due to enterococcus as well as E. coli.
The differences in waterline contamination between poultry house types could be attributed to the fact that conventional poultry houses, in general, were older than newly organic poultry houses (Table 1), allowing more time for contamination to occur.
