Contamination of Slippers in Operating Room by Dermatophytes and Effect of Antifungal Agent (Terbinafine) Disinfection / 대한의진균학회지

BACKGROUND: It is known that floor, clothes, shoes and slippers of common uses are the sources of infection by dermatophytes. However there hasn't been any report about the culture of dermatopytes from slippers in operating room. OBJECTIVE: The purpose of this study was to evaluate the contamination status of the slippers in operating room by dermatophytes and the effect of antifungal agent disinfection. METHODS: The samples were collected from 240 pairs of slippers that were used in common at operating room of Daegu Catholic University Medical Center with scrapping method. The collected samples were cultured on the media with chloramphenicol (500 mg/L) and cycloheximide (500 mg/L) to control the growth of nondermatophytic fungi. The same collection and culture was done again after the antifungal agent (terbinafine) disinfection. RESULTS: Dermatophytes were isolated from 22 (9.2%) pairs of slippers from a total of 240 pairs before the treatment, and 9 (3.8%) pairs after the treatment. There was significant difference in isolation rate between the slippers before the treatment and after the treatment (p=0.016). Trichophyton (T.) mentagrophytes and T. rubrum were isolated from the slippers and T. mentagrophytes (54.8%) was the most common isolated fungus. CONCLUSION: About ten percent of slippers in operation room were contaminated by dermatophytes. Regular antifungal agent disinfection on slippers in operating room will help to decrease in the prevalence of dermatophytes growth and prevent the nosocomial infection.

Two Methods for Disinfecting Slippers Contaminated in Operating Room:A Comparison / 中华医院感染学杂志

OBJECTIVE To explore the disinfection methods for slippers that used in operation room. METHODS A total of 120 pairs of slippers were monitored on their disinfection half of them were with automatic washer machine as a test group; while control group was dealed mannally with compound chlorine disinfection solution. The disinfection effects of two groups were compared. RESULTS The disinfection effects of two methods were identical, but had a difference of work efficiency. CONCLUSIONS The slippers used in operating room are contaminated by bacteria seriously. The manual disinfection method is low inefficient. The test group by machine method is with good efficiency and safety, so, it was recommendable for clinical use.

Contamination of Slippers by Dermatophytes / 대한의진균학회지

BACKGROUND: It is known that slippers, shoes, floor, and clothes of common uses are the sources of infection by dermatophytes but there are few reports of culture of it from these environments, especially in Korea. OBJECTIVE: The aim of this work was to evaluate contamination status of the slippers of adult school use by dermatophytes. METHODS: The samples were gathered from 70 pairs of slippers of adult school use with adhesive tape strip method and they were cultured on the media with cycloheximide (500 mg/L) and chloramphenicol (500 mg/L) to control the growth of nondermatophytic fungi. RESULTS: Dermatophytes were isolated from 33 (47.1%) out of a total of 70 pairs of slippers. Twenty four pairs of slippers (34.3%) were contaminated with Trichophyton (T.) mentagrophytes only; 8 (11.4%) with T. rubrum only; 1 (1.4%) with both of them. Thus, T. mentagrophytes was the most common isolate. The number of colonies of T. mentagrophytes, isolated from 25 pairs of slippers, was 97 (mean 3.88/pair), and that of T. rubrum from 9 pairs was 34 (3.78/pair). CONCLUSION: About forty seven percent of slippers of adult school use were contaminated by dermatophytes so that the control of tinea pedis would necessitate the simultaneous treatment of the infected individual and contaminated areas of the environment such as shoes and floor.
