The antibacterial activities of the essential oil of Eucalyptus globulus (EOEG) was determined against 7 fish pathogenic bacteria (Edwardsiella tarda, Streptococcus iniae, S. parauberis, Lactococcus garviae, Vibrio harveyi, V. ichthyoenteri and Photobacterium damselae) obtained from farmed olive flounder. The inhibitory activity was evaluated by three methods: Disc diffusion method, minimum inh...

Accurate detection of methicillin resistance (MR) in coagulase negative staphylococci (CoNS) is of utmost importance as infections due to CoNS are on the rise. Various phenotypic methods have been described for detecting mecA mediated MR with varying performance characteristics. The present study was designed to evaluate the performance of oxacillin and cefoxitin disc diffusion / MIC test and o...

For thousands of years, Punica granatum L. has been used in traditional medicine all over the world and predate the introduction of antibacterial drugs. The aim of the present study was to investigate the antibacterial activity of aqueous and ethanolic extracts of Punica granatum L. bark obtained by decoction and maceration. The different extracts of Punica granatum L. (Lythraceae) bark have be...

Invasive Neisseria meningitidis infection is rare but carries a high mortality rate. The carriage rate in the normal population is around 10% and can be higher in confined populations. A study on the prevalence of carriage of N. meningitidis was conducted among 3195 army recruits after 2 months of intensive training in an army camp. N. meningitidis was isolated from 37.0% of these recruits. Two...

The problem of dynamical heating of galactic discs by spiral density waves is discussed using the shearing sheet model. The secular evolution of the disc is described quantitatively by a diffusion equation for the distribution function of stars in the space spanned by integrals of motion of the stars, in particular the radial action integral and an integral related to the angular momentum. Spec...

Potential inhibitory effect of Citrus lemon (lemon) and Citrus sinensis (orange) on lipophilic, yeast like fungus, Malassezia furfur which causes Pityriasis versicolor, chronic superficial fungal disease of the skin have been studied by using two different methods: disc diffusion and microdilution methods. In screening of lemon and orange oil by disc diffusion method, the diameter of inhibition...

BACKGROUND AND AIM: Bacterial plaque is a biofilm which is related to its host and its exact role is proved in caries and periodontal disease. These days people brush their teeth and use mouthwash. In this research the effect of Jaman solution (Hezar Co., Iran) was compared with Biotene mouth rinse in an in-vitro study.METHODS: Biotene mouth rinse (Laclede Co., US) contains 4 antibacterial enzy...

ABSTRACT By means of three-dimensional high-resolution hydrodynamical simulations, we study the orbital evolution weakly eccentric or inclined low-mass protoplanets embedded in gaseous discs subject to thermal diffusion. We consider both non-luminous planets and that also experience radiative feedback from their own luminosity. compare our results previous analytical work find forces (the contr...

In a four-year period (July/2001-June/2005), 410 Haemophilus spp. isolates were studied. Those were isolated from sputum at Hospital Nossa Senhora da Conceição (NSC) in Porto Alegre city (RS). beta-lactamase enzyme was detected in 113 (27.6%) of isolates through chromogenic cephalosporin method. Fifty-eight (51.3%) of them showed sensibility to ampicillin through disc-diffusion method using Hae...

The increasing incidence of resistance to the antifungal agent, fluconazole, prompted the need for a rapid, reliable and easy-to-use susceptibility test. We have developed a disc diffusion test for fluconazole against Candida spp. suitable for a clinical laboratory. Disc diffusion tests on six different media were compared with MIC values. On the basis of correlation coefficient with MICs (r = ...
