Antifungal activity of essential oil and alcoholic extract of carum copticum against fluconazole-resistant and susceptible candida albicans isolated

ABSTRACT

Ajowan is an annual herbaceous essential oil of Carum copticom. The main components of the oil are Tymol, beta-pinene, gamma- terpinene and Sabinene. The fruit oil of Carum copticum has been reported to have several therapeutic effects including anti fungal, anti bacterial and anti viral, … Candida albicans is an opportunistic fungus and transforms into pathogenic form in favorable conditions, causing fungal diseases. In this study essential oil and alcoholic extract of Carum copticum were gained and Microdilution Broth method were used for detection of minimum inhibition concentration [MIC] and minimum fungicide concentration [MFC] of 11 clinical isolates of Candida albicans and Standard strain [PTCC50-27]. Results show that MIC for essential oil is 0.43 micro g/ml, 0.87 micro g/ml and for alcoholic extract is 3.51 micro g/ml, 7.03 micro g/ml, 1/75 micro g/ml. Thus, it seems that Carum copticum could inhibit Candida albicans growth by a similar mechanism which occurs by Fluconazole [FLZ]. In general, the results obtained in this study indicate that Carum copticum has potential values for growth inhibition of Candida albicans in vitro. In recent years, systemic fungal infections due to Candida species have been received major consideration about inducing mortality in nosocomial patients because of increasing in immunocompromised disorders such as AIDS and hematological disorders as well as long term use of broad spectrum antibiotics and corticosteroids. The present study was done with the aim of evaluating antifungal effects of essential oil and alcoholic extract from Carum copticum against Fluconazole [FLZ] susceptible and Fluconazole resistance Candida albicans strains isolated from different types of Candidiasis. Standard drug susceptibility tests with broth dilution technique were used to measure the in vitro antifungal activity of essential oil and alcoholic extract from Carum copticum. According to our results, it seems that Carum copticum could inhibit Candida albicans growth by a similar mechanism which occurs by FLZ and could be used as a potential antifungal agent especially with FLZ
