With isolated strams of dermatophytes, susceptibility tests were undertaken to antifungal drugs, and the results of both tests by inoculation of fungal suspensions and, fungal mats were compared, also the combined actior.s of drugs against isolated strains were evaluated, Diverse susceptibiIity patterns were observed among different fungal species, however, no arminor susceptibility differences were detected among strains of same species. Among drugs tested, tolnaftate showed the most strong antifungal ar.tion, and Ep, floccoaum was the most and T. mentagrophytes was the least sensitive species to drugs. MIC levels by mats inoculation were generally far higher than that of fungal suspension, particularly with tolnaftate it was several hundred folds higher by fungal mats inoculatian. Combined actions of drugs were generelly elevated against test strains, when miconazole cornbined with tolnaftate, the action was synergistic against T. mentagrophytes, and when tolnaftate combined with griseofulvin or siccarin cornbined with griseofulvin, thactions were elevated to T. rubrum.

Background: Vulvovaginal Candidiasis (VVC) is one of the frequent infections of the female genital tract and is the second most common cause of vaginal infections after bacterial vaginosis. According to the Centers for Disease Control and Prevention, azoles are the first‑line treatment for VVC. Among the azoles available in the Philippines, only miconazole and clotrimazole are recommended for both pregnant and non‑pregnant women. Objective: Compare the effect of miconazole versus clotrimazole in the treatment of vulvovaginal candidiasis among patients seen at the out‑patient department in a tertiary hospital Materials and Methods: This involved review of the records of patients diagnosed with VVC in a tertiary medical center from 2016 to 2020. All records of women, pregnant and non‑pregnant, wherein single‑dose 1200 mg miconazole or 6‑day 100 mg clotrimazole given vaginally were included Results: Eleven out of the 316 records (3.46%) remained symptomatic after treatment, about 18.1% (2/161) from those who used miconazole and 81.8% (9/155) from those treated with clotrimazole (p 0.027). In terms of failure rate, for miconazole it was 1.2% (2/161), whereas for clotrimazole it was 5.8% (9/155). None of the charts were found to have recorded adverse reaction to the given treatment Conclusion Single‑dose miconazole intravaginal regimen has a higher clinical cure rate than the 6‑day clotrimazole intravaginal treatment. Thereby, single‑dose intravaginal miconazole has the potential to improve patient compliance and treatment outcome at a lower cost

To determine the ocular toxicity of intravitreal miconazole, we conducted a controlled trial in 20 pigmented rabbit eyes(10 rabbits). An anterior chamber paracentesis was performed on all animals and 0.4 ml of perfluoropropane(C3F8) gas was injected intravitreally. On day three, when it was fully expanded, eyes were underwent C3F8/fluid exchange with vitreous replacement fluid. The infusion solution contained various amounts of miconazole, 0.5 microgram/ml. 1 microgram/ml, 5 microgram/ml, 10 microgram/ml, 50 microgram/ml, 100 microgram/ml and normal saline for control. Intravitreal infusion was performed for 25-30 minuteds and a total of 100-120 ml of fluid was replaced. Histopathological examination revealed retinal toxic reactions in concentrations of 10 microgram/ml or greater. This study suggests that infusion solution of 5 microgram/ml or less is the concentration exceeds the minimal inhibitory concentration for most of fungi and may be safetly used in the treatment of fungal endaphthalmitis.

The present study was designed to obtain omparative data on in vitro antifungal activities of imidazole derivatives. Minimum inhibitory oncentrations of clotrimazole, miconazole, econazole, ketoconazlole and griseofulvin on 4 strains of Trichophyton mentagrophytes, 3 strains of Trichophyton rubrum, 2 strains of Microsporum canis and ] strain of Sporothriv: schenckii were etermined after 3 week' incubation at room temperature on Sabouraud's dextrose liquid media. In addition, the fungicidal activities of miconazole and econazole were tested against Z'richophyton mentagrophytes and Microsporum canis, using the techniques described by Vanbreuseghern(1967) The results are summarzed as follows: ] In most of the dermatophytes studied, 1 to 10 pg/ml of M1C were detected. Diverse susceptibility pattern was observed among different fungal species, but no or minor variability was noted within the same species. The susceptibility of Z'ri- chophyton rubrum showed at MIC of 0. 01 to 10 pg/ml, T ichophyton mentagro- phyt.es and Mic osporum canis at 0.1 to 10 pg/ml and 0. 1 to 1000 gg/ml respec- tively. The Trichophyton rubrum was the most sensitive. In the susceptibility test of Sporothrix schenckii, the high resistance to clotrimazole and griseofuhin was observed. The fungistatic activities of miconazole, econazole and ketoconazole were observed only at concentrations higher than JpQ pg/ml.

BACKGROUND: The frequency of nosocomial bloodstream infections by Candida species has risen dramatically in the past two decades, and a noticeable shift in the species of Candida causing bloodstream infection toward non-albicans species has occurred. Also, the isolation frequency of Candida species are influenced by patient type, nation and region, study period, and investigators. The aim of this study is to investigate the isolation rates and antifungal susceptibility of Candida species isolated from blood cultures at Wonju Christian Hospital during the recent four years (1997~2000). METHODS: For one-hundred twenty-seven isolates of Candida species from blood cultures, we analyzed the isolation frequency by year, age/sex, and department. Identification of yeasts was done by germ tube test and ATB ID 32 C kit. Antifungal susceptibilities to flucytosine, amphotericin B, nystatin, miconazole, econazole, and ketoconazole were determined by ATB FUNGUS. RESULTS: The isolation rates of Candida species in decreasing order were C. albicans (44.9%), C. parapsilosis (21.3%), C. glabrata (14.2%), and C. tropicalis (9.5%). The isolation rates of Candida species by year were as follows; C. albicans decreased from 61.5% in 1997 to 33.3% in 2000; C. tropicalis decreased from 23.1% in 1997 to 5.0% in 2000; C. parapsilosis increased from 0% in 1997 to 30.8% in 2000; and C. glabrata increased from 7.7% in 1997 to 18.0% in 2000. Of 127 Candida species, all but one isolates were susceptible to amphotericin B. CONCLUSION: This data showed that the candidemia by C. albicans and C. tropicalis are decreasing trend, and candidemia by C. parapsilosis and C. glabrata are increasing trend in recent four years.

Miconazole is a synthetic imidazole with a broad spectrum of activity, low systemic and ocular toxicity. To determine the ocular toxicity of intravitreal injection of miconazole, we injected the drugs into the vitreous bodies of 44 rabbit eyes, doses varying from 5 microgram to 500 microgram dissolved in O.1ml of normal saline. Cataract, vitreous opacity, and retinal edema were observed in concentration of 100 microgram or greater, ophthalmoscopically. Histopathological examination revealed retinal toxicity in concentration of 50 microgram or greater. Retina showed hypertrophy of retinal pigment epithelium, clumping of pigments, and disorganization and loss of photoreceptor outer segment. In more advanced changes, subretinal deposits of macrophage and cellular debris, migration of photoreceptor nuclei into the subretinal space, and necrotic changes in all layers were observed.

This study was performed for the standardization and proper selection of effective antifungal agents by measuring the minimal inhibitory concentra-tions[MICs]of antifungals to fungi, separated from keratitis patients.Two strains of A.fumigatus and single strain of F.solani, A.falciforme, and A . alternata were used for this test.Standard powders of miconazole, itraconazole, clotrimazole, ketoconazole, and amphotericin B were used as antifungal agents. Microscopic and macroscopic measurements of MIC after 24, 48 and 72 hours of inoculation[105 conidia /ml]into YNB broth with culture temperature of 25 degrees C were performed by use of broth microdilution method.The results are as follows : itraconazole, amphotericin B, and clotrimazole were effective against A.fumigatus.F.solani showed resistance to all kinds of antifungal agents.A.falciforme and A.alternata were sensitive to amphotericin B and itraconazole, respectively. Further studies may be needed for the standardized measurement of MIC against filamentous fungi and also for in Vitro-in Vivo correlations for the treatment of fungal keratitis.

BACKGROUND: There have been several reports which assessed the activity of antifungals including azoles on Malassezia furfur by agar dilution method. However, they did not differentiate M. furfur into groups. In addition, the media for growth and minimum inhibitory concentration (MIC) determination, incubation temperature and length of incubation differed from each other. OBJECTIVE: The aim of this study was to test the antifungal activities of miconazole, clotrimazole, ketoconazole and itraconazole by determining MICs for M. furfur serovars A, B and C for these drugs. METHODS: MICs were determined by the agar dilution method. Leeming & Notman's Malassezia furfur agar medium was used. RESULTS: In all strains of serovars A, B and C, the MICs for miconazole were similar to those for clotrimazole ; MICs for ketoconazole were also similar to those for itraconazole ; MICs for miconazole or clotrimazole were higher than those for ketoconazole or itraconazole. CONCLUSION: The results suggested that ketoconazole or itraconazole could be used more effectively than miconazole or clotrimazole for the treatment of the diseases caused by M. furfur.

BACKGROUND: The epidemiology of Candida species isolated from nonsterile as well as normally sterile sites is important because colonization of the former may precede invasive Candida infections. METHODS: We investigated the epidemiology and antifungal susceptibility of Candida species recovered in Busan Paik Hospital during the past 6 years and compared these results according to the type of specimens. RESULTS: Among the 2364 strains, C. albicans (53.8%) was the most frequently isolated, followed by C. tropicalis (17.5%), and C. guilliermondii (10.0%). Non-albicans Candida species were more prevalent in normally sterile sites (P<0.001); the prevalence of C. tropicalis and C. parapsilosis was significantly higher in normally sterile than in nonsterile sites (P<0.001). The prevalence of C. parapsilosis was higher in blood, intravenous catheter tips, and ear discharge, whereas C. tropicalis was more frequently isolated from urine. C. guilliermondii was the most frequently isolated from bronchial washings. The susceptibilities of Candida species to 5-flucytosine, amphotericin B, nystatin, miconazole, econazole, and ketoconazole were 98.3, 99.3, 99.7, 94.9, 86.3, and 94.5%, respectively. The susceptibilities of the organisms from normally sterile sites were lower than those from nonsterile sites. CONCLUSION: The distribution of Candida species differed among various types of specimens, especially those from normally sterile versus nonsterile sites. We assume that the frequency of infections of exogenous origin is high. We presume that the candidemia of C. parapsilosis is associated with the use of central venous catheter and that C. parapsilosis is acquired from exogenous sources.

Clinical features of the dermatophyte infections of the glabrous skin can be altered by inappropriate treatment such as topical steroid treatment. We describe a case of dermatophyte infection with changes in clinical feature related to antifungal treatment. A 23-year-old woman presented with reddish annular scaly lesions on her right forearm. On the basis of the detection of hyphae on KOH examination, oral terbinafine 250 mg/day in combination with topical isoconazole was used for 3 weeks, but scattered papulopustules on erythematous bases occurred. Histopathologic examination revealed the presence of hyphae within the follicular infundibulum. Oral itraconazole 100 mg/day was administered for 2 weeks in combination with topical flutrimazole and produced a good clinical response. At her visit about 7 weeks after stopping itraconazole, agminated papulopustules on erythematous bases were seen on her right forearm. Trichophyton mentagrophytes was isolated on the culture of skin scraping from the surface of agminated lesions. She was successfully treated with oral fluconazole 150 mg weekly for 6 weeks and topical flutrimazole and isoconazole.
