- چکیده: مقدمه و هدف: در طی سالیان اخیر، بیماریهای عفونی ناشی از قارچهای فرصت طلب مانند Candida albicans و افزایش مقاومت باکتریهای بیماریای انسانی به آنتی بیوتیک های رایج منجر به بروز مشکلات زیادی در ارتباط با درمان این بیماری ها شده است. هدف از مطالعه حاضر بررسی اثرات ضد قارچی و باکتریایی عصاره گیاه اکالیپتوس بر علیه جدایه های Candida albicans جدا شده از نمونه های کلینیکی و تعدادی از جدایه های استاندارد از باکتری های بیماری زای انسانی بود.
روش تحقیق: عصاره اکایپتوس با استفاده از از دستگاه روتاری و روش خیساندن تهیه گردید. تعداد 30 جدایه از Candida albicans از بیماران مراجعه کننده به متخصص زنان و زایمان جدا شده و پس از خالص سازی به وسیله کلید های معتبر شناسایی شدند. در نهایت تعداد 30 جدایه برای بررسی اثر بازدارندگی رشد عصاره مورد استفاده قرار گرفتند. حداقل غلظت کشندگی و حداقل غلظت بازدارندگی عصاره اکالیپتوس علیه 5 سویه استاندارد باکتریایی شامل Staphylococcus aureu, Shigella dysenteriae, Listeria monocytogenes, Vibrio cholera and Bacillus cereusبا روش موردارزیابی قرار گرفت.
نتایج و بحث: نتایج ما نشان داد که در مقایسه با سویه های باکتریایی، جدایه های قرچی حساسیت بیشتری را نسبت به عصاره اکالیپتوس دارا می باشد. بیشترین و کمترین اثر کشندگی عصاره به ترتیب برای غلظت های 12.5 و 3.1 پی پی ام و علیه S. aureus و B. cereusثبت گردید. ماندد اثر کشندگی، بیشترین اثر بازدارندگی (20 پی پی ام) و کمترین اثر بازدارندگی (5پی پی ام) علیه S. aureus و B. cereusثبت گردید. حداقل غلظت کشندگی عصاره برای جلوگیری از رشد قارچی در غلظت 50 پی پی ام ثبت در حالی که بیشترین غلظت برای اثر بازدارندگی 150 پی پی ام ثبت گردید.
توصیه های کاربردی/ صنعتی: نتایج این مطالعه نشان داد که غلظت بالای اکالیپتوس قادر به بازدارندگی رشد قارچ Candida albicansمی باشد و در نتیجه مطالعات بیشتری در جهت آنالیز ترکیبات موثر در عصاره این گیاه می تواند انجام شود.- چکیده انگلیسی: Background & Aim:During recent decades, infections disease resulting from opportunistic fungi such as Candida albicans and resistance increasing of human pathogenic bacteria to current antibiotics has led to many problems for treating of these diseases. The aims of the present study was to investigate anti-fungi and anti-bacterial effects of Eucalyptus extract on Candida albicans species isolated from clinical samples and some standard human pathogenic bacteria.
Experimental: Eucalyptus extract was provided using rotary apparatus and maceration method. Thirty isolates of Candida albicans were isolated from referred patients to gynecologist and then were purified and identified by valid keys. Finally, 30 isolated were used to growth inhibitory activity assay. Minimum bactericidal concentration (MBC) and minimum inhibitory concentration (MIC) of eucalyptus extract against 5 standard bacteria inculding: Staphylococcus aureu, Shigella dysenteriae, Listeria monocytogenes, Vibrio cholera and Bacillus cereus were evaluated using micro broth dilution method.
Results: Our results indicated that in compare to bacterial strains, fungus isolates showed more sensitivity to eucalyptus extract. The highest and lowest MIC of extract was recorded at 12.5 and 3.1 ppm for S. aureus and B. cereus, respectively. As MIC, the maximum MBC (20ppm) and minimum MBC (5ppm) of extract was recorded fro S. aureus and B. cereus respectively. Minimum inhibitory concentration of extract to fungal growth inhibitory was 50 ppm, whereas the maximum inhibiting concentration was 150 ppm.
Recommended applications/industries: The positive and interesting results suggest the essential oil of E. globulus could be exploited antibiotic for the treatment of candidiasous disease caused by Candida albicans fungi, and some human pathogenic bacteria studied in this work.- انتشار مقاله: 01-06-1396

- چکیده انگلیسی: Background and aims: Herbal medicines are the major remedy in traditional medical systems and have a great contribution in maintaining human health and preventing many infectious diseases. The aim of this study was to assay antibacterial potential of Marrubium vulgare L. extract against Klebsiella pneumoniae resistant strains to current antibiotics and also GC/MS analysis to better understanding the extract composition. Methods: In this experimental research, 30 K. pneumoniae strains isolated from urine culture of hospitalized patients were used. The essential oil of Marrubium vulgare L. was obtained by hydro distillation for 2 hours using the Celevenger with yield of 75%. Methanolic extract from M. vulgare L. was prepared using Rotary apparatus. In order to determine chemical composition of essential oil, gas chromatography coupled with mass spectrometry (GC-MS) was performed. The minimum inhibitory concentrations and minimum bacterial concentrations were investigated to characterize the antimicrobial activities of this essential oil and its extract. Data were analyzed using analysis of variance (one-way) to determine the statistical differences between different tests. Results: The results showed that K. pneumoniae strains were resistant to 4 or 3 agents including: Ampicillin (65%), Gentamicin (30%), Sulfamethoxazol (25%). The lowest and the highest MIC value of M. vulgare L. extract were 2.5 and 10 mg/mL, respectively. The highest and the lowest MIC value of M. vulgare L. essential oil was 5 and 1/25 mg/m respectively. Conclusion: The present study confirmed that essential oil and extract of this plant could be served as an antibacterial agent in pharmaceutical industry.
