“…In this study the presence of Staphylococcus aureus, Pseudomonas aeruginosa, Bacillus substilis, Escherichia coli and Enterococcus faecalis were recorded within the sampled radiology units. These microbes are known to be nosocomial due to their colonization of clinical fomites [4,6]. As such, the presence of these microbes might be due to poor sterilization and sanitization procedures carried out on radiology equipment [1].…”

“…As such, the presence of these microbes might be due to poor sterilization and sanitization procedures carried out on radiology equipment [1]. The resistance to common cleaning agents and antibiotics has made Staphylococcus aureus renown in radiology units [3,4] hence, its high frequency of occurrence than other bacterial isolates.…”

“…All the strains of S auresus from the various units showed the presence of mecA gene as exemplified in Plate 1. However, the high antibiotic susceptibility pattern of the isolates in addition to MRSA isolates goes to show that there is no direct relationship between the effect of antibiotics and the effect of X-ray exposure on the isolates [4]. Therefore, the resistance of S. aureus to various antibiotic drugs seems not to be a good indicator for evaluating its possible resistance to X-ray radiation [24].…”

“…The Radiology Department of every hospital plays a major role in medical diagnosis, it regularly receives large number of patients resulting in high human traffic which results in the transmission of nosocomial pathogens amongst patients and Radiology Staff [1]. Some of the commonly found pathogens are Staphylococcus aureus, Staphylococcus epidermidis, Candida albicans, Bacillus substilis, Escherichia coli and Pseudomonas aeruginosa [2,3,4]. Among these microbes, Staphylococcus aureus poses a serious threat to hospitals due to its ability to acquire mecA gene conferring resistance to the antibiotic methicillin.…”

Aim: Methicillin-resistant Staphylococcus aureus (MRSA) and other nosocomial pathogens are frequently isolated from the Radiology Department of hospitals. These pathogens are repeatedly exposed to refracted electromagnetic radiations during diagnostic clinical X-ray imaging sessions. This study thus investigated the effect of these refracted radiations on the nosocomial bacteria found within Radiology units and their possible survival mechanism. Methodology: Swab samples were collected from three (3) Radiology units; plain radiography machine, ultrasound machine and mammography machine. The samples were cultured and identified following standard microbiology procedures. The identified bacterial isolates were exposed to X-rays at different KVp and MAs factors, cell counts and catalase activities of the isolates were determined using standard procedures. Results: The bacterial isolates identified were Staphylococcus aureus, Pseudomonas aeruginosa, Bacillus subtilis, Escherichia coli and Enterococcus faecalis where Staphylococcus aureus had the highest prevalence (29.41%) and Enterococcus faecalis (11.76%) was least. The highest survival level to KVp and MAs exposure was S. aureus with values 11.16 ± 0.86 x103 and 19.50 ± 0.16 x103 cfu/ml respectively while Enterococcus faecalis was least with negative value. There was a positive correlation between catalase activity and cell survival with R-value of 0.2512 and 0.6925 for KVp and MAs exposure factors respectively. Conclusion: The study revealed that clinical X-ray does not completely eliminate nosocomial pathogens within Radiology Department and MRSA is a formidable bacterium in the units.
