The Inhibitory Effect of Iraqi Propolis Extract Against Three isolates of Candida Albicans

Abstrak Candida albicansb (C. albicans) adalah salah satu mikroorganisme penyebab masalah kesehatan reproduksi wanita, yaitu keputihan (fluor albus). Penggunaan larutan povidone iodine dan bahan alam seperti ekstrak daun sirih menjadi pilihan masyarakat sebagai pembersih alat kewanitaan. Tujuan penelitian ini adalah untuk membandingkandaya hambat larutan antiseptik povidone iodine dan ekstrak daun sirih terhadap jamur C. albicans secara in vitro. Penelitian dilakukan terhadap lima isolat jamur C. albicans dengan larutan kontrol akuades.Perlakuan terdiri dari povidone iodine, ekstrak daun sirih dengan konsentrasi 5%, 10%, dan 20%.Hasil penelitian menunjukkan bahwa povidone iodine memiliki daya hambat terhadap C. albicans. Ekstrak daun sirih dengan konsentrasi 5% dan 10% tidak memiliki daya hambat terhadap C. albicans, namun ekstrak daun sirih konsentrasi 20% memiliki daya hambat terhadap C. albicans. Analisis statistik dengan uji ANOVA yang dilanjutkan dengan uji Post-hoc menunjukkan perbedaan bermakna antara daya hambat larutan povidone iodine dan ekstrak daun sirih 20% terhadap kontrol(p < 0.05).Larutan povidone iodine memiliki daya hambat dua kali lebih besar terhadap pertumbuhan C. albicans dibandingkan ekstrak daun sirih 20%. Dari penelitian ini dapat disimpulkan bahwa larutan povidone iodine dan ekstrak daun sirih 20% dapat menghambat pertumbuhan jamur C. albicans secara in vitro. Kata kunci: povidone iodine, ekstrak daun sirih, Candida albicansAbstract Candida albicans (C. albicans) is one of the frequent causes of reproductive health problems in women, namely vaginal discharge (fluor albus). The antiseptic solution, povidone iodine, is still an option to overcome vaginal discharge. The use of natural materials such as betel (Piper betle L.) leaves extract also become a popular choice as adouche for women. The objective of this study was to compare the inhibitory activity of povidone iodine solution and betel leaf extract against the growth of C. albicans in vitro. We used five different isolates of C. albicans with distilled water as control. Each isolate was treated with povidone iodine solution, betel leaf extract at concentration of 5%, 10%,and 20%. The results showed that povidone iodine had inhibitory effect on C. albicans. Betel leaf extract at concentration of 5% and 10% did not have inhibitory effectwhile betel leaf extract at concentration of 20% hadinhibitory effect on C. albicans. Analysis by ANOVA followed by Post-hoc tests showed a significant difference in inhibitory activity of povidone iodine and betel leaf extract at 20% concentration compared to control (p < 0,05). Povidone iodine solution showed twice as much as inhibitory effect on C. albicans compared to betel leaf extract (20% concentration). It is concluded that povidone iodine solution and betel leaf extract at 20% concentration can inhibit the growth of C. albicans in vitro.Keywords: povidone iodine, betel leaf extract, Candida albicans

Candida Albicans Biofilms

ABSTRACT Most manifestations of candidiasis are associated with biofilm formation on biological or inanimate surfaces. Candida albicans biofilms are recalcitrant to treatment with conventional antifungal therapies. Here we report on the activity of caspofungin, a new semisynthetic echinocandin, against C. albicans biofilms. Caspofungin displayed potent in vitro activity against sessile C. albicans cells within biofilms, with MICs at which 50% of the sessile cells were inhibited well within the drug's therapeutic range. Scanning electron microscopy and confocal scanning laser microscopy were used to visualize the effects of caspofungin on preformed C. albicans biofilms, and the results indicated that caspofungin affected the cellular morphology and the metabolic status of cells within the biofilms. The coating of biomaterials with caspofungin had an inhibitory effect on subsequent biofilm development by C. albicans. Together these findings indicate that caspofungin displays potent activity against C. albicans biofilms in vitro and merits further investigation for the treatment of biofilm-associated infections.

Drug Resistant Strains

(1) Background: Few antifungal drugs are currently available, and drug-resistant strains have rapidly emerged. Thus, the aim of this study is to evaluate the effectiveness of the antifungal activity from a combinational treatment of chitosan with a clinical antifungal drug on Candida albicans and Candida tropicalis. (2) Methods: Minimum inhibitory concentration (MIC) tests, checkerboard assays, and disc assays were employed to determine the inhibitory effect of chitosan with or without other antifungal drugs on C. albicans and C. tropicalis. (3) Results: Treatment with chitosan in combination with fluconazole showed a great synergistic fungicidal effect against C. albicans and C. tropicalis, but an indifferent effect on antifungal activity when challenged with chitosan-amphotericin B or chitosan-caspofungin simultaneously. Furthermore, the combination of chitosan and fluconazole was effective against drug-resistant strains. (4) Conclusions: These findings provide strong evidence that chitosan in combination with fluconazole is a promising therapy against two Candida species and its drug-resistant strains.

Propolis Extract

Objective. To evaluate the antimicrobial activity of soft and purified propolis extracts. Study object and methods. Antimicrobial activity of soft and purified propolis extracts was determined with reference cultures of Staphylococcus aureus ATCC 25923, Enterococcus faecalis ATCC 29212, Escherichia coli ATCC 25922, Klebsiella pneumoniae ATCC 33499, Pseudomonas aeruginosa ATCC 27853, Proteus mirabilis ATCC 12459, Bacillus subtilis ATCC 6633, Bacillus cereus ATCC 8035, and fungus Candida albicans ATCC 60193. Microbiological tests were performed under aseptic conditions. Minimum inhibitory concentration (MIC) – the highest dilution of preparation (the lowest concentration of preparation) that suppresses growth of reference microorganisms – was determined. Results. Concentration of phenolic compounds in soft propolis extract that possesses antimicrobial activity against gram-positive (Staphylococcus aureus, Enterococcus faecalis) and gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa, and Proteus mirabilis) is 0.587±0.054 mg and 0.587±0.054–0.394±0.022 mg (P>0.05) and in purified propolis extract – 0.427±0.044 mg and 0.256±0.02 mg (P>0.05). Klebsiella pneumoniae is most resistant to soft propolis extract when the concentration of phenolic compounds is 1.119± 0.152 mg and to purified propolis extract when the concentration of phenolic compounds is 1.013±0.189 mg (P>0.05). Spore-forming Bacillus subtilis bacteria are more sensitive to soft and purified propolis extracts when the concentration of phenolic compounds is 0.134±0.002 mg and 0.075±0.025 mg, respectively, and Bacillus cereus – when the concentration is 0.394±0.022 mg and 0.256±0.02 mg (P>0.05). Sensitivity of fungus Candida albicans to soft and purified propolis extracts is the same as Bacillus subtilis. Encapsulated bacterium Klebsiella pneumoniae is most resistant to antimicrobial action of soft and purified propolis extracts as compared with gram-positive Staphylococcus aureus and Enterococcus faecalis bacteria (P<0.05), gram-negative Escherichia coli, Pseudomonas aeruginosa, and Proteus mirabilis (P<0.05), sporeforming Bacillus subtilis and Bacillus cereus bacteria (P<0.05), and fungus Candida albicans (P<0.05). There is no statistically significant difference between antimicrobial effect of soft propolis extract and purified propolis extract on gram-positive bacteria, gram-negative bacteria, spore-forming bacteria, encapsulated bacteria, and Candida fungus. Conclusions. Soft and purified propolis extracts possess antimicrobial activity. They could be recommended as natural preservatives in the manufacture of pharmaceutical products.
