Antifungal activity of antimicrobial fibers

Introduction: The growth and accumulation of microorganismes on the textile surfaces that compromises the hygienic and clealiness, because this kind of textils can be made according to possible uses: Protective clothing, hospital uses, home textiles, bandages & dressing of the wounds, so antimiecrobial fibers were prepared. Aim: Studing the effect of antifungal activity of amtimicrobial fibers. Materials and Methods: In this investigation we used two different methodes for evaluoting antifungal activity of antimicrobial fibers, the methodes are: disck plate & flask shake test. In experimental states Aspergillus niger PTCC 5011 and Candida albicans PTCC 5072 which are different types of fungus strains were used, in addition different types of fibers. Different experment, that had three kinds of control as flowing were accomplished, 1- fibers control (nonantimicrobial fibers+ fungus) 2- Positive control of growth of fungus (culture media without fibers+fungus) 3- Negative control of fungus growth (Pure antimicrobial solution+ fungus) Also antimicrobial activity of different fibers with variable percentage of this antimicrobial material (30%, 60%, 100%) were evaluated. Fungus spores with (104- 105/ml) was added to different flasks containing test specimen & buffer phosphate. After sampling at different time (O. 24h & 48h), the number of fungus are counted by agar plate method at 30°C with 3 repeated the same test. Results: The results indicated that the most activity of antifungal was by 100% Solution pure on these fungi, but the fiber with different additive Solutions of antimicrobe are not efficient on the A. niger, however in case of Candida albicans fibers the reducible effect (92. 41% & 91. 57%>) on the number Candida albicans was noticed and with 30% antimicrobial additive no antifungal effect was revealed. Conclusion: considering the results fibers with 100% antimicrobial material can be used against Candida albicans
