مقايسه ي اثر كشندگي سه نوع ماده ضدعفوني كننده بر قارچهاي فرصت طلب عفونت زاي بيمارستاني

Nosocomial infections or those infections, which a patient acquires during his hospital stay from the hospital environment have always been an important health problem. Such infections are usually resistant to the routine antibiotics and can even lead to death of the patient.The rate of incidence of these infections is directly related to the hygienic conditions of the hospitals. Taking into consideration the fad that Prevention is the hest cure, appropriate proper use of antiseptics and disinfectants is the best approach towards these infections.The aim of this study was to determine and compare the appropriate concentrations of 3 solutions; savlon, betadine and dettol for their optimal fungicidal action, The test organisms were three fungi ; aspergilus nijer, candida albicans and mucour. The study was carried out according to the standard method (NFT67-1500) issued by the French Institute of Standards and the methods recommended by AOAC for the evaluation of the fungicidal effects of antiseptics and disinfectants. After the preparation of the fungal suspensions from spores of the test organisms, the neutralization effect of each chemical was determined.The results showed that 7.5% savlon, 4.5%dettol and 10% betadine were the best effective concentrations for killing the three test organisms in this study.Although the above-mentioned chemicals are fungicidal in the recommended concentrations, the most reasonable and appropriate way is preventing the entry of fungi or other microorganisms in hospital environments. It is therefore necessary to prevent the introduction of infective agents into hospital environments by applying suitable health measures.
