Background: Oral candidiasis is an oral infection caused by Candida albicans. It is one of the most common opportunistic infections found in patients with Human Immunodeficiency Virus (HIV)/Acquired Immune Deficiency Syndrome (AIDS). Due to growing resistance and side effects to common antifungal drugs in recent years, there have been many studies on naturalsubstances as antifungal agents. In this study, Epigallocatechin gallate (EGCG) were examined for in vitro antifungal activity against Candida strains. Purpose: To compare the in vitro antifungal activity of EGCG and nystatin towards Candida sp. isolate in HIV/AIDS patients with oral candidiasis. Methods: This research was an experimental laboratory study conducted at the Dr. Soetomo General Academic Hospital, Surabaya. Forty isolates of Candida albicans and Candida non-albicans were included. The isolates were tested for antifungal activity using the well diffusion and microdilution method for nystatin 1000 IU and EGCG 1.25%. Result: Diffusion test results showed a greater inhibition zone for nystatin against all analyzed Candida strains with an average diameter for Candida albicans formed by EGCG of 2.15 mm and 7.4 mm for Candida non-albicans. Meanwhile, based on the microdilution test, EGCG was better than nystatin towards all analyzed Candida strains. This study showed EGCG Minimum Fungicidal Concentration (MFC) as high as 50% (p < 0.05). Conclusion: Nystatin antifungal activity was better than EGCG supported by a greater inhibition zone in the well diffusion method. However, the antifungal activity of EGCG was better than nystatin based on microdilution methods.

Background: Probiotic bacteria have been emerging as a trustworthy choice for the prevention and treatment of Candida spp. infections. This study aimed to develop and characterize an orodispersible film (ODF) for delivering the potentially probiotic Enterococcus faecium CRL 183 into the oral cavity, evaluating its in vitro antifungal activity against Candida albicans. Methods and Results: The ODF was composed by carboxymethylcellulose, gelatin, and potato starch, and its physical, chemical, and mechanical properties were studied. The probiotic resistance and viability during processing and storage were evaluated as well as its in vitro antifungal activity against C. albicans. The ODFs were thin, resistant, and flexible, with neutral pH and microbiologically safe. The probiotic resisted the ODF obtaining process, demonstrating high viability (>9 log10 CFU·g−1), up to 90 days of storage at room temperature. The Probiotic Film promoted 68.9% of reduction in fungal early biofilm and 91.2% in its mature biofilm compared to the group stimulated with the control film. Those results were confirmed through SEM images. Conclusion: The probiotic ODF developed is a promising strategy to prevent oral candidiasis, since it permits the local probiotic delivery, which in turn was able to reduce C. albicans biofilm formation.

Background: The most common opportunistic infection obtained in patients with Human Immunodeficiency Virus (HIV)/Acquired Immune Deficiency Syndrome (AIDS) is Oral Candidiasis (OC). Currently widely reported about increased fluconazole resistance, as a therapy that is often used in patients with HIV/AIDS with OC. For this reason, effective antifungal agents are needed as alternative therapies. Several studies have reported some antifungal activity from rosemary essential oils. Purpose: The aim of this study is to evaluate the antifungal activity between rosemary essential oils and fluconazole against the isolates used by Candida sp. taken from HIV / AIDS patients with OC. Methods: This research was an experimental laboratory study with a post-test only design of 40 Candida sp. isolates from HIV / AIDS patients with OC in the Outpatient Unit and Inpatient Installation of the Infectious Disease Intermediate Care Unit (UPIPI) Dr. Soetomo General Academic Teaching Hospital, Surabaya. Examination of antifungal activity using conventional test methods with disk diffusion. Result: Disk diffusion test result revealed average inhibition zone of rosemary essential oil in Candida albicans 1,75±3,64 mm and Candida non-albicans 1,5±3,08 mm, while the average inhibition zone of fluconazole in Candida albicans 17,9±8,62 mm and Candida non-albicans 4,85±7,9 mm. There was significant difference (p <0.001) between the inhibition zone formed in Candida albicans by fluconazole and rosemary essential oil, but no significant difference of inhibition zone formed in Candida non-albicans. Conclusion: Antifungal activity fluconazole has greater than Rosemary essential oils in Candida albicans.

Background: Oral candidiasis is the most common clinical manifestation in a person infected with HIV which has been linked with the severity of the disease. Candida albicans responsible for most oral candidiasis. The increased resistance to the available antifungal drugs can reduce the efficacy of therapy. Therefore, it will be crucial to discover novel antifungal agents. One of them is tea tree oil (TTO) or Melaleuca alternifolia which has a potent antifungal effect to inhibit the growth of Candida sp.  Purpose: To evaluate the antifungal susceptibility of TTO 5% compared with nystatin against Candida sp. taken from HIV/AIDS patients. Methods: The study assessed the antifungal effect of TTO 5% and nystatin against 33 isolates of Candida sp. that was isolated from the oral cavity of 30 HIV/AIDS patients in Dr. Soetomo General Academic Teaching Hospital Surabaya, Indonesia. Antifungal susceptibility was evaluated by the disc diffusion method. The diameter of the inhibition zone was determined as the result of this study. Result: The most strains found in this study was Candida albicans (84.8%). The mean inhibition zone of nystatin against all strains was 23.24 mm whether it was 17.55 mm for TTO 5%. The inhibition zone of both TTO 5% and nystatin in Candida non-albicans were tended to be higher than in Candida albicans. It revealed that the inhibition zone of TTO 5% significantly lower than nystatin (P = 0.00; P < 0.05).Conclusion: Therefore, the antifungal susceptibility of nystatin was significantly higher than TTO 5% against Candida albicans and non-albicans.

The biocontrol strain P1 of Trichoderma harzianum was genetically modified by targeted disruption of the single-copy ech42 gene encoding for the secreted 42-kDa endochitinase (CHIT42). Stable mutants in which ech42 was interrupted, and unable to produce CHIT42, were obtained and characterized. These mutants lacked the ech42 transcript, the protein, and endochitinase activity in culture filtrates, and they were unable to clear a medium containing colloidal chitin. Other chitinolytic and glucanolytic enzymes expressed during mycoparasitism were not affected by the disruption of ech42. The disrupted mutant D11 grew and sporulated similarly to the wild type. In vitro antifungal activity of the ech42 disruptant culture filtrates against Botrytis cinerea and Rhizoctonia solani was reduced about 40%, compared with wild type; antifungal activity was fully restored by adding an equivalent amount of CHIT42 as secreted by P1. The mutant exhibited the same biocontrol effect against Pythium ultimum as strain P1, but the antagonism against B. cinerea on bean leaves by the mutant was significantly reduced (33% less biocontrol), compared with strain P1. Conversely, the endochitinase-deficient mutant performed better than the wild type (16% improvement of survival) in biocontrol experiments in soil infested with the soilborne fungus R. solani. These results indicate that the antagonistic interaction between the T. harzianum strain and various fungal hosts is based on different mechanisms.

The main goal of this study was to investigate the antifungal activity of clove oil against candida albicans of vaginal candidiasis in females from Syria. An in vitro study was carried out using the following Candida albicans strains involved in vaginal candidiasis using the well diffusion (WD) testing.Candida albicans (ATCC 90028) and 15 strains were compiled from Aleppo University Hospital. These strains were collected from women having vaginal candidiasis. The antifungal activity of clove oil was determined in the form of inhibition zone using antifungal assay by agar WD testing.In all experiments, the obtained results indicated that clove oil has inhibitory effects on Candida albicans (ATCC 90028) and against15 fungal strains. This study showed that clove oil was active against the tested Candida albicans strains. Clove oil was more effective against Candida albicans compared to the antifungal antibiotics nystatin, ketoconazole and itraconazol. Clove oil may have potential for use in the development of clinically useful antifungal preparations. Therefore, clove oil might be clinically effective in the natural prevention treatment of vaginal candidiasis.
