Background: Ozone gas possesses antimicrobial properties against bacteria, viruses, and yeasts. Previously, we demonstrated the efficacy of ozone in killing ATCC strains of the dermatophyte fungi Trichophyton rubrum and Trichophyton mentagrophytes. Objective: To test the efficacy of ozone gas in sanitizing onychomycosis patient footwear contaminated with fungal material as a means of minimizing the risk of reinfection. Methods: Swabs of footwear from onychomycosis patients were cultured prior to and after ozone exposure to test the ability of ozone to sanitize these items. Results: We identified contamination of footwear from most onychomycosis patients, a potential source of reinfection in these individuals. Furthermore, ozone gas was effective in sanitizing contaminated footwear. Conclusion: Ozone gas is effective in sanitizing footwear and represents a novel adjunct therapy to be used in conjunction with antifungal medications and/or devices to better treat onychomycosis and tinea pedis patients in both the short and the long term.

In Vitro Antifungal Susceptibility

Investigations on antifungal drug susceptibility were carried out on 90 clinical isolates of Trichophyton rubrum, and Trichophyton mentagrophytes with four antifungal drugs, namely griseofulvin, fluconazole, itraconazole and terbinafine as suggested by National Committee for Clinical Laboratory Standards (NCCLS) M27–A (1997) document by broth macrodilution method to standardize in vitro antifungal susceptibility testing and to find out the Minimum Inhibitory Concentration (MIC) of the drugs. In this study, terbinafine was found to be the most efficient drug for all isolates. Terbinafine had the lowest MIC range of 0.001 g/ml to 0.09 g/ml and MIC50 was low at 0.005 g/ml and MIC90 was also low at 0.04 g/ml against T.rubrum; and MIC range of 0.001μg/ml to 0.19μg/ml with a MIC50 of 0.01μg/ml and MIC90 at 0.09μg/ml against T.mentagrophytes. Itraconazole showed antifungal activity superior to that of fluconazole, with a MIC range of 0.04g/ml to 1.56g/ml, with MIC50 at 0.19μg/ml and MIC90 at 1.56g/ml against T.rubrum; and MIC range of 0.04μg/ml to 1.56μg/ml, with MIC50 at 0.19μg/ml and MIC90 at 0.78μg/ml against T.mentagrophytes. Griseofulvin appears to be still a potent drug for management of dermatophytoses. Griseofulvin had a MIC range of 0.15g/ml to 5.07 g/ml with MIC50 at1.26 g/ml and MIC90 at 2.53 g/ml against T.rubrum; and MIC range of 0.31μg/ml to 5.07μg/ml with MIC50 at 1.26μg/ml and MIC90 at 2.53μg/ml against T.mentagrophytes. Fluconazole showed a high MIC range of 0.19 g/ml to 50 g/ml and MIC50 was high at 1.56g/ml and MIC90 was also high at 12.5 g/ml against T.rubrum; and a high MIC range of 0.09μg/ml to 25.0μg/ml, with MIC50 at 1.56μg/ml and MIC90 at 12.5μg/ml towards T.mentagrophytes. The technique was found to be easy to perform and reliable with consistent results.

Dermatophytes are by far the most significant fungi because of their widespread involvement of population at large and their prevalence all over the world. This is an attempt to observe the spectrum of dermatophytes among the clinically suspected cases of dermatophytosis attending the outpatient department of Dermatology and Venereology, Bangabandhu Sheik Mujib Medical University, Dhaka. Three hundred and twenty clinically suspected cases of dermatophytosis were subjected to mycological studies. One hundred and five cases (32.8%) were positive for fungus in direct microscopy while 97(30.3%) were culture positive. Tinea unguium was the most common clinical type encountered followed by tinea corporis. Dermatophytosis was more common in the age group of 21-30 years. The male to female ratio was 1.54:1. Trichophyton rubrum 84(86.6%) was found common etiological dermatophyte species followed by Trichophyton mentagrophytes 8(8.2%) and Epidermophyton floccosum 5(5.2%).DOI: http://dx.doi.org/10.3329/bjmm.v6i2.19370 Bangladesh J Med Microbiol 2012; 06(02): 11-14
