In vitro study of antifungal effect of carica papaya peel var. California extract against Candida albicans

Candida albicans is a normal microflora in the oral cavity which can be an opportunistic pathogen that could cause oral candidiasis when there are underlying predisposing conditions. Papaya as one of the most widely grown herbal plants in Indonesia has been known to cure diseases. Unused papaya peel only became a waste; however, the papaya peel is known to contain active compounds that have antifungal effect, especially raw ones. This study aimed to determine the antifungal effect of raw papaya peel extract of Californian variety and determine the minimum inhibitory concentration (MIC) of this extract on clinical isolates of C. albicans. This study was an experimental laboratory study with post-test only control group design. Ethanol-based extract of papaya peel was obtained from maceration process using 96% ethanol. Antifungal effect testing was carried out in vitro using disc diffusion method (Kirby-Bauer) on clinical isolates of C. albicans. The concentration of Ethanol extract of papaya peel used consisted of 2.5%, 5%, 10%, and 20% with positive control (nystatin) and negative control (distilled water). The results showed that 2.5%, 5%, 10%, and 20% papaya peel extracts were able to inhibit the growth of C. albicans with 2.5% concentration of raw papaya peel extract as minimum inhibitory concentration. Ethanol extract of raw papaya peel of Californian variety with 2.5%, 5%, 10%, and 20% concentrations has small antifungal effect against clinical isolates of C. albicans.

The goal of this study was to compare in vitro and in vivo efficacy of moxifloxacin and liposomal amphotericin B (Amp-B) monotherapies and combination treatment against Candida albicans in an exogenous endophthalmitis model in rabbit eyes. Microplate dilution tests and checkerboard analysis were performed to detect in vitro efficacies. Endophthalmitis was induced by intravitreal injection of C. albicans in 40 rabbit eyes with simultaneous intravitreal drug injection according to prophylactic treatment groups. Group 1 (control group) received 0.1 mL of balanced salt solution, group 2 (moxi group) 100 µg moxifloxacin/0.1 mL, group 3 (Amp-B group) 10 µg liposomal Amp-B/0.1 mL, and group 4 (combi group) both 100 µg moxifloxacin/0.05 mL and 10 µg liposomal Amp-B/0.05 mL intravitreally. Clinical examination, quantitative analysis of microorganisms, and histopathologic examination were performed as in vivo studies. The minimum inhibitory concentration of liposomal Amp-B against C. albicans was found to be 1 µg/mL. Moxifloxacin showed no inhibition of in vitro C. albicans growth. The minimum inhibitory concentration values of liposomal Amp-B for C. albicans were reduced two- to eightfold with increasing concentrations of moxifloxacin in vitro. In vivo, there was no C. albicans growth in the combi group (zero of eight eyes), whereas three eyes (37.5%) showed growth in the Amp-B group. Vitreous inflammation, retinal detachment, focal retinal necrosis, and outer nuclear layer loss were found to be lower in the moxi group compared with the control group. Ganglion cell and inner nuclear layer loss was observed in all eyes (100%) in both the moxi and combi groups, whereas only in 25% (two of eight eyes) in the Amp-B group. Moxifloxacin strongly augments the efficacy of liposomal Amp-B against C. albicans in vitro, although it has no in vitro antifungal activity when used alone. It is interesting that we found a synergistic effect for in vitro tests but failed to demonstrate it in vivo. When 100 µg moxifloxacin/0.1 mL is given intravitreally, it has some toxic effects that are limited to the inner retinal layers.

The present study was conducted to investigate the bio-activities of ethanol extract of Etlingera linguiformis (Roxb.) R.M.Sm. as well as to determine the chemical profiles of the extract. The antibacterial and antifungal activities of the crude extract were evaluated by the disc diffusion method against 4 Gram positive and 7 Gram negative pathogenic bacteria and 7 fungi using Ciprofloxacin and Fluconazole as standards, respectively. The minimum inhibitory concentration (MIC) was determined by the serial dilution method. The anti-atherothrombosis activity was assessed by using Streptokinase (SK) as standard. Moreover, the in-vitro anti-inflammatory and membrane stablization tests were performed. In the anti-bacterial and antifungal activity test, the zones of inhibition were found within the range of 10.0-15.0 and 10.0-22.0 mm, respectively. The highest zone of inhibition was obtained against Bacillus cereus (15.0 mm) and Blastomyces dermatitidis (22.0 mm). In the minimum inhibitory concentration (MIC) test the crude extract inhibited the growth of Blastomyces dermatitidis significantly at 31.2 ?g/ml. In the anti-atherothrombosis activity test, the extract revealed moderate clot lysis by 15.15%. Moreover, the extract produced inhibition of protein denaturation and haemolysis by 34% and 38.98% in the in vitro antiinflammatory and membrane stablization tests. Preliminary phytochemical screenings of the crude extractives demonstrated the presence of alkaloids, steroids, tannins, reducing sugars and gums. The extract also exhibited good biological activities. Therefore, the plant should be subjected to systematic bioactivity guided isolation in order to obtain the active molecules.

During a screening for antifungal secondary metabolites, six new mono-/bis-alkenoic acid derivatives (2–7) and one known alkenoic acid derivative (1) were isolated from an endophytic fungi Scopulariopsis candelabrum. Their chemical structures were identified by 1H-NMR, 13C-NMR, 2D NMR, and high-resolution mass spectrometry, as well as comparisons with previously reported literatures. Among them, fusariumesters C‒F (2–5) are bis-alkenoic acid derivatives dimerized by an ester bond, while acetylfusaridioic acid A (6) and fusaridioic acid D (7) are alkenoic acid monomers. All the isolates were submitted to an antifungal assay against Candida albicans and the corn pathogen Exserohilum turcicum using the filter paper agar diffusion method. As a result, only compound 1 decorating with β-lactone ring turned out to be active against these two tested fungi. The broth microdilution assay against Candida albicans showed the minimum inhibitory concentration (MIC) value of 1 to be 20 μg/ml, while the minimum inhibitory concentration value of the positive control (naystatin) was 10 μg/ml. And the half maximal inhibitory concentration (IC50) value (21.23 μg/ml) of 1 against Exserohilum turcicum was determined by analyzing its inhibition effect on the mycelial growth, using cycloheximide (IC50 = 46.70 μg/ml) as the positive control.

Background and Purpose: Candida albicans is an important microorganism in the normal flora of a healthy subject; however, it has an expedient pathogenic character that induces hydrolytic virulence. Regarding this, the present study aimed to find an in vitro alternative that could reduce the virulence of this yeast. Materials and Methods: For the purpose of the study, the effect of amphotericin B (AmB) combined with the extract of Traganum nudatum (E1) or Mentha pulegium (E2) was evaluated against the hydrolytic activities of esterase, protease, and phospholipase. This effect was determined by calculating the minimum inhibitory concentration (MIC), used to adjust the extract/AmB mixtures in culture media. Results: The evaluated Pz values, which corresponded to the different enzymatic activities, showed a decrease in the hydrolytic activities of C. albicans strains after the addition of E1/AmB and E2/AmB combinations at descending concentrations (lower than the obtained MICs). Conclusion: Based on the findings, it would be possible to reduce the pathogenesis of this species without destabilizing the balance of the flora.

Thymol (THY) was found to have in vitro antifungal activity against 24 fluconazole (FLC)-resistant and 12 FLC-susceptible clinical isolates of Candida albicans, standard strain ATCC 10231 and one experimentally induced FLC-resistant C. albicans S-1. In addition, synergism was observed for clinical isolates of C. albicans with combinations of THY–FLC and THY–amphotericin B (AMB) evaluated by the chequerboard microdilution method. The interaction intensity was determined by spectrophotometry for the chequerboard assay, and the nature of the interactions was assessed using two non-parametric approaches [fractional inhibitory concentration index (FICI) and ΔE models]. The interaction between THY–FLC or THY–AMB in FLC-resistant and -susceptible strains of C. albicans showed a high percentage of synergism by the FICI method and the ΔE method. The ΔE model gave results consistent with FICI, and no antagonistic action was observed in the strains tested.

The data of the influence of active substances of anthelmintic and antiprotozoal preparations on the growth of L. casei IMB B-7280 and E. coli 055K59 are provided in the article. Their minimal inhibitory concentrations were determined for these strains of microorganisms and the active substances with which possible simultaneous application of probiotic strain L. casei IMB В-7280 is established. With this aim, the effect on the growth of L. casei IMB B-7280 and E. coli 055K59 and the minimum inhibitory concentration of fenbendazole, levamisole and ivermectin, which are part of the anthelmintic preparations and amprolium, tylosin, sodium sulfadimexone and sodium sulfatyazole, which are active substances of antiprotozoal drugs, were investigated. The determination of the minimum inhibitory concentration of the active substances of antiparasitic agents against these strains of microorganisms was carried out in in vitro experiments by serial dilutions in a dense MRS environment and MPA, and a study of the effect on the growth by diffusion method, followed by measurement of growth retardation zones in millimeters. It is established that among active substances of anthelmintic preparations only phenbendazole caused growth retardation and only relative to L. casei IMB B-7280. Among the active substances of antiprotozoal drugs, sodium sulfatyazole was the most active, which inhibited growth as L. casei IMB-7280 and E. coli 055K59 № 3912/41. Thylosin was effective only in relation to L. casei IMB B-7280 and at the highest concentration of 0.03%, the growth retardation zone was 23.4 ± 0.92 mm. Sodium sulfadimetoxin caused the growth retardation of L. сasei IMB В-7280 only at the highest concentration. The minimum inhibitory concentration of active substances of anti-parasitic drugs was different for strains L. casei IMB B-7280 and E. coli 055K59 № 3912/4. The strongest inhibitory effect was shown by tylosin, which stopped the growth of L. casei IMB B-7280 and E. coli 055K59 № 3912/41 respectively at concentrations of 0.00125 and 50.0 mg/ml. Active substances such as amprolium, levamisole and ivermectin did not significantly inhibit the growth of L. casei, IMB B-7280 and E. coli 055K59 № 3912/41, since their minimal inhibitory concentration was in the range of 4000 to 6000 mg ml.
