The resistance of Helicobacter pylori to antibiotics leaves great influence on treatment outcome. Routine antimicrobial susceptibility testing of H. pylori should be a simple, inexpensive and standardized method to be adopted. Agar and broth dilution techniques are difficult to perform and not practical. E-test and disk diffusion methods have the advantage of allowing the visualization of resis...

BACKGROUND The objective of this paper was to study antimicrobial activity and safety of Enterococcus faecium KQ 2.6 (E. faecium KQ 2.6) isolated from peacock feces. METHODS Agar well diffusion method was adopted in antimicrobial activity assay. Disk diffusion test was used to determine the antibiotic resistance. The identification and virulence potential of E. faecium KQ 2.6 were investigate...

Antimicrobial treatments result in the host's enteric bacteria being exposed to the antimicrobials. Pharmacodynamic models can describe how this exposure affects the enteric bacteria and their antimicrobial resistance. The models utilize measurements of bacterial antimicrobial susceptibility traditionally obtained in vitro in aerobic conditions. However, in vivo enteric bacteria are exposed to ...

plants are potent biochemists; biologically active compounds present in the medicinal plants have always been ofgreat interest to scientists working in this field. thus, the aim of the current study was to screen the antimicrobial activity of acacia nilotica, ziziphus mauritiana, bauhinia variegate and lantana camara against some selected clinical isolated strains. although previous studies hav...

conclusions according to these findings, antibiotic-resistance patterns have changed, and vancomycin resistance, especially among e. faecium, is rising because of nosocomial infections. consequently, it has become a serious subject for patients admitted into a hospital. results a total of 53 enterococci were isolated from clinical samples of blood, urine, wounds, sputum, and cerebrospinal fluid...

background : incidence of  white  spots due  to  demineralization of  enamel  and  gingival problems  is  an  unacceptable  result  of  orthodontic  treatment.  plaque  accumulation  and bacterial biofilm growth are responsible for these phenomena. the resin-based dental composites used as bonding agents in orthodontics play a major role in mentioned problems. as recent researches assert the an...

THE PROBLEM OF ANTIMICROBIAL RESISTANCE HAS BEEN evident almost from the time antimicrobial drugs entered the pharmacopoeia. However, the clinical impact of resistance has been difficult to measure for a variety of reasons, including separating out the effect of underlying illness and the availability of at least 1 effective drug for most infections. Antimicrobial resistance also has economic c...

Nowadays, there are a number of colorimetric techniques available for the determination of a time killing assay in a manner much easier and faster than those previously more commonly used, which were much more time-consuming and laborious colony counting procedures. Here, an attempt has been made to test the antimicrobial peptides of Citropin 1.1, Palm-KK-NH2, and Temporin A on a reference stra...

We consider of the antimicrobial activity on the Ag nanoparticles(Ag NPs) aqueous solutions, which was prepared using a stabilizer, such as poly(N vinyl 2 pyrrolidone PVP , for Staphylococcus aureus) S aureus and Escherichia coli E coli by measuring the minimum inhibitory concentration MIC . Antimicrobial effect of Ag NPs for S aureus and E coli was investigated using disk diffusion method Also...
