Some constituents of snake venom have been found to display a variety of biological activities. The antibacterial property of snake venom, in particular, has gathered increasing scientific interest due to antibiotic resistance. In the present study, king cobra venom was screened against three strains of Staphylococcus aureus [including methicillin-resistant Staphylococcus aureus (MRSA)], three ...

Microorganisms are not commonly found in the planktonic state but predominantly form dual- and multispecies biofilms in almost all natural environments. Bacteria in multispecies biofilms cooperate, compete or have neutral interactions according to the involved species. Here, the development of mono- and dual-species biofilms formed by Staphylococcus aureus and other foodborne pathogens such as ...

The objective of this study was to extract, characterize, and examine the antibacterial properties orange essential oil obtained from citrus sinensis peels, using hydro-distillation method. Various components were characterized by FTIR, UV-Vis GC- MS spectroscopic techniques. extracted conformed AFNOR standards, had a maximum yield 3.4% (w/w). results showed that limonene major bioactive (97.14...

In this study, based on our previous derivatives of naphtho[2,3-b]furan-4,9-diones were synthesized and their antimicrobial activities evaluated. The screening these naphthoquinones revealed that the fluorine-containing NQ008 compound exhibited potent broad against Gram-positive bacteria including methicillin-resistant Staphylococcus aureus (MRSA), Gram-negative bacteria, fungi. results ratio m...

Annulated pyrano[2,3-d]pyrimidine/pyrano[2,3-d]uracil derivatives were synthesized using aromatic aldehydes, active methylene compounds and barbituric acid in presence of dibutylamine (DBA) catalyst in ethanol as solvent. The different substituents on phenyl ring in the fused pyrano uracil skeleton showed productive influence on its antimicrobial activity against some gram positive and gram neg...

In vitro antibacterial activity of crude aqueous and organic extracts of rhizome of Zingiber officinale Roscoe (ginger) was studied against both Gram-negative (Escherichia coli and Salmonella typhi) and Gram-positive (Bacillus cereus, Bacillus subtilis, Staphylococcus aureus and Streptococcus pyogenes) bacterial strains. The present study reveals that the pattern of inhibition varied with the s...

The aim of this study was to investigate bacterial contamination on surfaces randomly selected Automated Teller Machine and their sensitivity antibiotics in São Paulo city, Brazil. swabs collected aseptically were inoculated selective non-selective media triplicate incubated at 37 °C for 24 h. After Gram staining the isolated colonies, complementary biochemical tests applied. antibiotic pattern...

Introduction: The use of radiopharmaceuticals is a powerful tool in the management of patients with infectious or inflammatory diseases in nuclear medicine. In this study ofloxacin as a second-generation fluoroquinolone is used to design a desired infection imaging agent after labeling with 99mTc via direct labeling. Methods: Ofloxacin was radiolabeled with 99mTc using di...
