The in vitro activity of rifampin alone and in combination with oxacillin was determined for 75 Staphylococcus aureus strains (64 susceptible and 11 resistant to oxacillin). Minimal inhibitory concentrations (MICs) and minimal bactericidal concentrations (MBCs) were determined by broth microdilution; antibiotic combinations were evaluated by microdilution checkerboard and time-kill studies. The...

In bacterial infections, including urinary tract infections (UTIs), the gap between development of new antimicrobials and antimicrobial resistance is dramatically increasing, especially in Gram-negative (Gram–) bacteria. All healthy products that can be used per se or may sources antibacterial compounds should considered fight against this major public health threat. present study, phytochemica...

Aim: The study evaluates the phytochemical screening, atomic absorption spectroscopy (AAS), Gas chromatography–mass spectrometry (GC-MS) and antibacterial activities of aqueous methanolic extracts turmeric (Curcuma longa) rhizome against Escherichia coli (E. coli) Staphylococcus aureus (S. aureus). 
 Place Duration Study: was carried out for six months in 2020 Biochemistry
 Laboratory...

Due to the emergence of bacterial resistance in phytopathogenic microorganisms, it is necessary search for new treatment alternatives these pathogens. Natural extracts are a potential source bioactive compounds that can act against such strains. The antibacterial activity Larrea tridentata bacteria with public health importance has been documented; however, few reports cover pathogens associate...

Pumpkin leaf plant (Cucurbita moschata D.) is commonly used to treat gastric pain, jaundice, hipercholesterol, and contains antibacterial compounds. Nature products derived from plants are often facial skin disease by inhibiting acne-causing bacteria. Staphylococcus epidermidis has important role in acne formation. This research aims determine the activity, Minimum Inhibitory Concentration (MIC...

Polygonum aviculare (Polygonaceae) is an herb commonly distributed in Mediterranean coastal regions in Egypt and used in folkloric medicine. Organic and aqueous solvent extracts and fractions of P. aviculare were investigated for antimicrobial activities on several microorganisms including bacteria and fungi. Phytochemical constituents of air-dried powered plant parts were extracted using aqueo...

objective: the aim of this study was to determine the minimum inhibitory concentration (mic) and minimum fungicidal or bactericidal concentration (mfc, mbc) of oleo-gum resin of ferula assafoetida on the growth of food spoilage microbes of bacteria, yeasts and fungal and investigation of the most sensitive of them to oleo-gum resin of these plant. methods: in this study oleo-gum resin of f.assa...

This was an in vitro study that aimed to evaluate the antimicrobial effect of propolis extract caffeic acid phenethyl ester (CAPE) on four different oral microorganisms. Seven concentrations CAPE (0.2, 0.5, 1, 1.5, 2, 3, and 4 mg/mL) for use against Staphylococcus aureus, Streptococcus mutans, oralis, salivarius were determined using minimum inhibition concentration (MIC), bactericidal (MBC), b...

BACKGROUND The indiscriminate use of antibiotics in the treatment of infectious diseases can increase the development of antibiotic resistance. Therefore, there is a big demand for new sources of antimicrobial agents and alternative treatments for reduction of antibiotic dosage required to decrease the associated side effects. OBJECTIVES In this study, the synergistic action of aminoglycoside...

BACKGROUND Oxacillin continues to be an important agent in the treatment of staphylococcal infections; many generic products are available and the only requirement for their approval is demonstration of pharmaceutical equivalence. We tested the assumption that pharmaceutical equivalence predicts therapeutic equivalence by comparing 11 generics with the innovator product in terms of concentratio...
