Abstract

As regards the extensive problem of hospital infections and their control, the Authors point out that a very meaningful factor is at present the spreading of opportunistic agcnts. This phenomenon gives the reasons for the importance of disinfection as a critical stage of preventive policy in hospital environment. From this point of view the Authors had carried out a research using the Kelsey and Maurer test (1974) for the evaluation of the effectiveness of some disinfectants towards opportunistic agents isolated from clinical and cnvironmental specimens from hospital wards. In detail: ethyl alcohol 70%; glutaraldehyde 2%; chlorhexidine gluconate 0.05%; povidone-iodine 10%; benzoxonium chloride 1%; benzalkonium chloride 0.25% + ethyl alcohol 70% were tested toward strains of the following microorganisms: Pseudomonas aeruginosa; Serratia marcescens; Acinctobacter calcoaceticus; Stapbylococcus aureus; Candida albicans. The results confirmed a good activity of glutaraldehyde, povidone-iodine, ethyl alcohol and QACs + alcohol, but some resistances to chlorhexidine and to aqueous Qacs were showed especially in « dirty conditions ». Among the differcnt microrganisms, the highest resistance levels (30%) were showed by gram negative rods, as more sensitive were Acinctobacter calcoaceticus, Stapbylococcus aureus and Candida albicans. The Authors come to the conclusion that the values pointed out are not very high but they confimi the need of monitoring the resistance trends in hospital and of making a careful choice of disinfectans.
