Background:The spread of drug-resistant microbial strains has led many studies for identifying, designing, and synthesizing new antimicrobial agents.The aim of this study was to evaluate antimicrobial effects of some synthesized potassium dithiocarbazinate derivatives against 6 Gram-negative and 4 Gram-positive bacteria as well as 2 molds and 1 yeast. Potassium salts of dithiocarbazinic acids w...

The ability of Streptococcus pneumoniae to escape lysis and killing by vancomycin, a property termed "tolerance," has recently been noted in a laboratory strain of the species. Vancomycin tolerance in clinical isolates represents a potential new health risk. We determined the prevalence of vancomycin and penicillin tolerance among 116 clinical isolates of pneumococci by monitoring lysis and via...

Purpose: To evaluate the anti-enterobacterial potential of nine ethnobotanically selected plants traditionally used in different parts of India for the treatment of gastrointestinal disorders such as cholera, diarrhea or dysentery. Methods: The methanol extracts of these plants were screened for antibacterial activity against 11 strains of enteropathogenic bacteria, including multi-drug resista...

607 Abstract: In this study; inhibitory and bactericidal activities of cefoperazone + sulbactam against Pseudomonas aeruginosa strains were determined in two studies first in 1992 and second in 1994. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values were determined by following the microdilution method recommended by NCCLS (Approved Standard M7-A2 1990) ...

Background: The study was conducted to determine the antimicrobial activity of varying concentrations of Lantana camara Linn. leaf extracts against Staphylococcus aureus, Bacillus subtilis and Escherichia coli. Methods: Broth microdilution method was used to determine the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) was evaluated through streaking of bacte...

Pet turtles are well-known to harbor an array of bacterial pathogens which can cause zoonotic infections in humans as well as opportunistic infections in the turtles itself. Essential oils are the natural plant extracts which have been traditionally used for disease treatment. In the present study, the essential oil of lavender (EOL) was examined for its antibacterial activity against thirty-ei...

Staphylococcus aureus, the main cause of nosocomial infection worldwide result in significant increases in mortality, morbidity, and cost related to prolong treatments. Silver compound has been in use since time immemorial for the treatment of burns, wounds and several other bacterial infections. In the present work, we explore the antibacterial activity of silver nanoparticles (Ag-NPs) dispers...

Background Staphylococcus aureus, methicillin-resistant and Escherichia coli, multidrug-resistant included in the list of antibiotic-resistant priority pathogens from WHO. As multidrug-resistant bacteria problem is increasing, it is necessary to probe new sources for identifying antimicrobial compounds. Medicinal plants represent a rich source of antimicrobial agents. One of the potential plant...

conclusions extracts of u. dioica showed significant antibacterial effect against some clinically important pathogenic bacteria. based on the obtained results it can be concluded that u. dioica is useful as antibacterial and bactericidal agent in treating infectious diseases. materials and methods hydroalcoholic extracts from aerial parts were prepared using aqueous solution of ethanol and meth...
