Antimicrobial activity of the roots of Eranthemum roseum (Vahl) R.Br. (Dasmuli), were tested against different bacteria (including Escherichia coli, Staphylococcus aureus, Bacillus subtilis, Shigella sonnei, Klebsiella pneumoniae, Salmonella typhi, Proteus vulgaris, Pseudomonas aeruginosa) and fungi (such as Candida albicans and Aspergillus niger) by cup plate diffusion method. Minimal Inhibito...

Biofilms are defined as aggregation of single cell microorganisms and associated with over 80% of all the microbial infections. Pseudomonas aeruginosa is a Gram-negative opportunistic pathogen capable of leading to various infections in immunocompromised people. Recent studies showed that norspermidine, a kind of polyamine, prevented and disrupted biofilm formation by some Gram-negative bacteri...

Thymol is the main volatile compound extracted from dried fruits of Tachyspermum ammi Mill. The compound serves as a biological marker because of its interesting biological activities and is used in traditional medicine, as a bactericide, fungicide, Gastro-intestinal disorders, Bronchitis and asthma, and others. A GC method for the determination of thymol was developed. Chromatographic analysis...

BACKGROUND Ozone is an unstable gas, capable of oxidizing any biological entity. It is an effective bactericide in its gaseous as well as aqueous form. AIMS The objective of this study was to determine the in-situ antimicrobial effect of 0.1 ppm ozonated water on plaque and salivary microorganisms. SUBJECTS AND METHODS 24 h old supragingival plaque (SP) was collected from the two most poste...

Many cereals accumulate hydroxamic acids involved in defense of plant against various fungi, bacteria, and insects. 2,4-dihydroxy-7-methoxy-1,4-benzoxazine-3-one, commonly known as DIMBOA, is one of the principal cyclic hydroxamic acids in aqueous extracts of maize. The aim of this study was to evaluate the antibacterial activity of the isolated DIMBOA and its derivatives 2-benzoxazolinone (BOA...

The most common bacterial diseases in pond-raised channel cat¢sh Ictalurus punctatus (Ra¢nesque) are enteric septicemia of cat¢sh and columnaris, caused by Edwardsiella ictaluri and Flavobacterium columnare respectively. Medicated feed containing antibiotics is one management approach that cat¢sh producers use in the treatment of bacterial diseases. However, the future use of all types of medic...

in this note, by considering the notions of the intuitionistic general l-fuzzy automaton and $(alpha, beta)$-language, we show that for any $(alpha, beta)$-language $mathcal{l}$, there exists a minimal intuitionistic general l-fuzzy automaton recognizing $mathcal{l}$.we prove that the minimal intuitionistic general l-fuzzy automaton is isomorphic with threshold $(alpha,beta)$ to any $(alpha, be...

conclusions antimicrobial and antitoxigenic properties of natural products need a firmly established criterion before they could be offered to application. results a significant reduction in aflatoxin production was noted which was not due to the inhibitory effect but because of antifungal property of the oil. interestingly, the oil promoted toxin production for the reasons yet to be investigat...

b ackgro un d : the antimicrobial activity of silver nanoparticles has been investigated in medical fields in recent years, but there are few studies regarding its effect on oral microorganisms. the aim of the present study was to evaluate the in vitro antimicrobial and toxicity properties of nanosilver against two dental plaque microorganisms  and human gingival fibroblast (hgf) cell line. me ...
