The microbial contamination in food packaging has been a major concern that has paved the way to search for novel, natural anti-microbial agents, such as modified α-mangostin. In the present study, twelve synthetic analogs were obtained through semi-synthetic modification of α-mangostin by Ritter reaction, reduction by palladium-carbon (Pd-C), alkylation, and acetylation. The evaluation of the ...

background chlorhexidine gluconate (chx) is the most common antimicrobial agent used against oral pathogens, however information on its ability to inhibit and disrupt anaerobic single and multispecies biofilms is relatively unknown. objectives the purpose of this study was to test the efficacy of chx for its biofilm inhibition and disruption properties using crystal violet assay. materials and ...

background :  science the discovery of antibiotic, the incidence of antibiotic resistance has been inevitable. although there has been many study in these area but problem still exists. the aim of this research was to study the serotyping and multiple antibiotic resistance patterns of shigella sonnei isolated from diarrheal stool of children.   methods :  the stool samples of children from zero...

introduction: glycyrrhiza glabra (licorice) root, a member of the pea family has been used since ancient times as both food and medicine. licorice has been used as an antioxidant, antimicrobial and anti inflammatory in researches .extraction of this medical plant is used as the basis of anti-ulcer medicine for treatment of peptic ulcer. patients and methods: in the present study, licorice decoc...

anti-microbial effects of the lactic acid bacteria have been studied and proved in various investigations. this investigation aimed to study the anti-yeast effect of two isolated lactic acid bacteria species from “chal” (a product from yogurt) as biological preservatives in doogh. to do so, anti-yeast activity of l. brevis and e. faecium against saccharomyces cerevisiae, kluyveromyces. marxianu...

Due to the increase of microbial resistance to antibiotics and the occurrence of side effects, use of medicinal plants with anti-microbial properties seems to be rational. Hence, in this study, some plants of the Apiaceae, Asteraceae, Brassicaceae, and Cucurbitaceae families were evaluated for antimicrobial effects. The aerial parts of the plants were extracted by different solvents using a Sox...
