In the present study, we evaluated antimicrobial activity of clove oil against a range of fungal pathogens including that responsible for urogenital infection. Clove oil was found to possess strong antifungal activity against opportunistic fungal pathogens such as Candida albicans, Cryptococcus neoformans and Aspergillus fumigatus, etc. The oil was found to be extremely successful in the treatment of experimental murine vaginitis in model animals. On evaluating various formulations, topical administration of the liposomized clove oil was found to be most effective against treatment of vaginal candidiasis.

In the present study, we evaluated tuftsin bearing nystatin liposomes for their potential against an isolate of Candida albicans (C. albicans) showing less in vivo susceptibility to amphotericin B (Amp B). The liposomised-Amp B in higher doses was found to be effective in elimination of less susceptible strain of C. albicans (C. albicans JMCR) in Balb/c mice, but may not be recommended due to toxicity constraints. On the other hand, liposomal nystatin was shown to possess higher efficacy as compared to that of Amp B, and was pertinent in treatment of C. albicans JMCR strain. The data of present work reveals that the incorporation of nystatin in tuftsin-bearing-liposomes results in a significant increase in its efficacy against experimental murine candidiasis. Interestingly, the pre-treatment of animals with liposomised-tuftsin prior to challenge with C. albicans infection was more effective in elimination of the pathogen from host and shows an advantage in prophylactic perspectives.
