عنوان انگلیسی Evaluation of the Correct Use of Virkon Disinfectant in Reducing Bacterial Contamination of Platelets Components Prepared
چکیده انگلیسی مقاله Background: The purpose of the present study was to test the bactericidal effect of virkon on native species of bacteria seen in Iran by selecting a suitable concentration of virkon which would effectively reduce the level of environmental bacterial contamination including contamination of platelets components while following the exact instruction of the use of the disinfectant. Methods: This was an interferal -applied study. 160 samples were taken from laboratory benches, instruments and outer surface of blood component bags. The growing organisms were identified by using the McFarland constant standard protocols and the CFU/ml of bacteria was determined. Later all the laboratory benches and instruments involved in the preparation of platelet components were disinfected using (1%) virkon solution. 101 samples were taken from disinfected areas and swabs were plated on to standard bacteriological media and plates were read. In addition, 1100 segments from platelet bags were separated and the platelet contents were plated and any bacterial growths were assessed using quality control department guidelines. Results: Out of 169 samples which were plated before disinfection by virkon following organisms were separated 56/8% gram positive b. (spore forming and without spores) 96 samples, 59/8% gram positive cocci (staph. &strept.) 101samples, 94/8% gram negative b. 159 samples, 82/2% gram negative cocci 139 samples. Post disinfection by virkon solution, out of 101 samples following organisms was separated: 24/8% gram positive b. 25 samples, 16/8% gram positive cocci 17 samples, 0% gram negative b. 5/9% gram negativ 6 samples, out of 1100 segment separated from platelets bags 4 samples (segments) had bacterial growth (0036%) 2 samples had gram positive b. growth and 2 samples had staph. Conclusion: By using correct concentration of virkon solution and following the exact manufactures instruction for use we were able to observe log reduction in bacterial contamination of the areas that blood components were made hence strong bactericidal action of specific concentration of virkon solution (1%) was present.
