Sagebrush genus (Artemisia scoparia) is the one of the most important genus of Asteraceae family. It has numerous values because of medicine properties. Sagebrush genus has numerous application in traditional medicine from ancient times. In this research, the isolation and identification of essential oil and antibacterial activity of Artemisia scoparia have been studied. Samples were collected ...

background and objectives:   staphylococcus aureus is one of the main causatives of bovine mastitis. resistance of some strains to methicillin, can complicate the treatment of its infections. on the other hand, enterotoxin production is also im- portant. therefore, the aim of our study was to investigate the methicillin resistance and enterotoxin production in s. aureus isolates caused bovine m...

antibiotic resistance of intensive care unit (icu) born aerobic gram-negative bacteria was evaluated during a six months period at a teaching hospital in tehran, and determination of the validity of the results obtained from disc diffusion tests, using discs manufactured in iran. disc susceptibility tests using iranian and standard discs (diffusion discs available in international markets) were...

Fastidious organisms present problems in antimicrobial susceptibility testing related to particular cultural requirements or slow growth. Methods for commonly isolated fastidious organisms, including haemolytic streptococci, Neisseria spp. and Haemophilus spp., are included in the description of the standardized disc diffusion method. However, some further information is given here for Haemophi...

OBJECTIVE The activity of voriconazole against Aspergillus spp. (n = 77) was tested by the Etest, disc diffusion and the NCCLS M38-A methods. METHODS Four Rhizomucor spp. isolates were included to study the suitability of the three susceptibility testing methods to detect isolates resistant to voriconazole. The disc diffusion method performed on Mueller-Hinton agar (Difco) supplemented with 2...

orange peel extract solution contains mucilage flavor and three types of glycosides. limonene is one of the terpenoides in some vegetables, fruits and food; that plays as an antioxidant in juice. as it has anti-microorganism effects on some bacteria, we carried out the antifungal effects of limonene versus orange extract. in the present study the effects of orange extract and two types of limon...

conclusion adc, fa, and t2* values may quantitatively reflect the microstructural characteristics of np, therefore they could be used to detect the minimal changes of early ldd. results the adc, fa, and t2* values were different (p < 0.05) among different rois within the same disc or among corresponding rois in different level discs. while the average values of adc increased regularly with the ...

In this study, the antimicrobial activity of three solvent extracts of consortium (mixed culture) of commercial available probiotic bacteria against eight fish pathogens using well diffusion and disc diffusion assay method. The probiotic bacteria inhibited almost all the fish pathogens tested. All tested strains were significantly inhibited at probability level (P<0.5).Zone of inhibition was hi...

background and objectives: antibacterial susceptibility testing of clinical bacterial isolates through disk diffusion method plays a major role in antibacterial treatment. one of the main factors affecting the result of these tests is the type, structure and quality of the disks. the main objective of this study was to compare the agreement of antibiotic disks originated from three companies on...
