Garcinia forbesii is traditionally used as medicine and cosmetics. The aimed was to determine antibacterial activity of ethanolic extract fraction pericarp against Staphylococcus aureus Propionibacterium acne based on the diameter inhibition zone, minimum inhibitory concentration (MIC) killing (MBC). results showed that largest zone indicated by ethyl acetate 5.08±1.020 mm 14.33±3.326 mm. MIC v...
BACKGROUND This study evaluated the in vitro activity of essential oil extracted from the leaves of Myracrodruon urundeuva. METHODS The oil was obtained by hydro-distillation and characterized by Gas Chromatography coupled to Mass Spectrometry (GC-MS) and Gas Chromatography with Flame Ionization Detector (GC-FID). The antibacterial activity was evaluated by the broth microdilution technique a...
Aim To evaluate the antimicrobial activity of hydroalcoholic extracts of pomegranate (Punica granatum L.) peel and juice, against the microorganisms considered the main etiologic agents of dental caries. Methods The values of the minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) were determined against Streptococcus mutans Clarke ATCC® 25175™ strain and R...
resistance of streptococcus pneumoniae against penicillin is considered to be of great importance. while low-resistant strains could be treated by penicillin, treatment of highly resistant strains is very difficult and needs broad-spectrum antibiotics. this study was performed in imam khomeini medical center, tehran, iran, from 1999 to 2001 to evaluate pneumococcal resistance against penicillin...
honey is a popular food product produced by honey bees that it is a well-known antimicrobial and antioxidant activity. floral origin of honey plays an important role on its biological properties.this research was carried out to evaluate the antibacterial and antioxidant activity of four sample honey with different floral origin collected from the bee hive in the golestan province in north of ir...
The efficacy of ATP synthase inhibitor TMC207 was assessed in early and late Mycobacterium avium infections in mice. In contrast to what was earlier observed for M. tuberculosis, a bacteriostatic effect was obtained. In vitro, the minimal bactericidal concentration (MBC)/MIC ratio was very high. The MBC was more relevant for assessment of pharmacokinetic/pharmacodynamic relationships than the MIC.
تاثیرات سوء بکارگیری آنتیبیوتکها و مواد ضد عفونیکننده شیمیایی خصوصاً ایجاد مقاومتهای دارویی در آبزیان پرورشی سبب گردیده تا بررسی امکان جایگزینی مواد مذکور با موادی با منشاء طبیعی مانند گیاهان دارویی از مهم ترین اولویتهای تحقیقاتی محققین بهداشت و بیماریهای آبزیان قرار گیرد. این مطالعه با هدف بررسی تأثیر عصارههای سیر allium sativum و آویشن شیرازی zataria multiflora بر باکتری آئروموناس هیدرو...
objective: bioactive glass 45s5 is a surface reactive glass-ceramic biomaterial, developed in 1969. bag 45s5 with particle size of 20-60 nm has the ability of bone regeneration, broad spectrum antibacterial effect, repairs and replaces diseased or damaged bone. the aim of this study was to evaluate the antibacterial activity and determine mic and mbc values of nano-bag45s5 on streptococcus muta...
سابقه و هدف: فعالیت ضد میکروبی اسانس و عصاره های گیاهی از سال ها قبل، مورد توجه بوده است. مشکلات و کمبود های بسیاری در کنترل بیماری های باکتریایی گیاهی وجود دارد. از لحاظ تاریخچه ای، ترکیبات طبیعی گیاهی از منابع مهم با خاصیت درمانی به شمار می آیند. این مطالعه با هدف بررسی ترکیب شیمیایی و فعالیت های ضد باکتریایی اسانس و عصاره درمنه کوهی (artemisia aucheri) انجام شد. مواد و روش ها: در این مطالعه...
Antimicrobial susceptibility testing was conducted with 6 different spirochetal strains (4 strains of Leptospira spp. and 2 strains of Borrelia burgdorferi) against 3 antimicrobial agents, commonly used in equine and bovine practice. The ranges of MIC and MBC of amoxicillin against Leptospira spp. were 0.05 - 6.25 microgram/ml and 6.25 - 25.0 microgram/ml, respectively. And the ranges of minima...
