background bacterium-bacterium antagonistic interactions could be important in the ecology of marine bacteria. antimicrobial properties of microorganisms are exploited in various fields of human activities. objectives antagonism of heterotrophic bacteria from different marine environments of tropical and temperate zones was examined. materials and methods bacteria were isolated from biofilm sam...

Different organic and aqueous extracts of leaves of Cassia occidentalis L (Caesalpiniaceae) were screened for their antimicrobial activity against seven human pathogenic bacterial and two fungal strains by disk diffusion assay. The pattern of inhibition varied with the solvent used for extraction and the microorganism tested. Among these extracts, methanol and aqueous extracts showed significan...

Mastitis is one of the most costly diseases in the dairy industry. The use of antibiotics in the treatment of mastitis Leads to bacterial resistance and health problems for consumers. This study aimed to determine the antibacterial properties of essential oil of Thymus vulgaris on the bacteria Staphylococcus aureus, Escherichia coli and Staphylococcus were agalactia. Antibacterial properties of...

An experiment was conducted in the Biological Dep. College of Science, Kufa University to determine the antagonism activity of Lemon and Lime juices against some bacteria e.g. Esherichia coli, Klebsiella pneumonia, and Shigella flexneri. Results of this experiment revealed that all juices concentrations have inhibiting effects against bacteria due to the presence of citric acid and some volatil...

The use of Moringa oleifera seed in water purification has reduced the chemical-based coagulants which is detrimental to both human and livestock. This project aimed at testing microbial properties M. oil extract on some selected pathogens (Bacterial fungi). was extracted using Soxhlet apparatus with ethanol as solvents. Gas-chromatography-mass spectrometry (GCMS) analyses were carried out for ...

Aloe vera has many health benefits, containing saponins, aloin anthraquinone complex, barbaloin, isobarbaloin, athranol, aloemodin, cinnamic acid, chrysophanic reistanol and essential oils. The aim of the study was to determine effect extract on growth Salmonella typhi bacteria. Research is experimental. Methods with Kirby Bouer. Concentrations were 100%, 70% 50% chloramphenicol control Muller ...

An oxidative polymerization approach was used to create polyaniline (PANI) and Fe2O3 /PANI nanoparticle combination. Various characterization approaches were investigate the structural, morphological, structures. The findings support synthesis of polycrystalline PANI spherical composites. Gram-positive bacteria are tested for antibacterial activity. quantities Nanoparticles composites test Stap...

plants or natural resources have been found to be a good alternative method for nanoparticles synthesis. in this study, polyaniline coated silver nanoparticles (agnps) synthesized from piper betle leaves extract were investigated for their antibacterial activity. silver nanoparticles were prepared from the reduction of silver nitrate and nabh4 was used as reducing agent. silver nanoparticles an...

Pathogenic bacterial infections have become a major health problem worldwide. New antimicrobial agents are urgently needed to overcome this problem. In this study, antibacterial activity of Nigella sativa seed extract against some pathogenic bacterial strains (Streptococcus pyogene, Pseudomonas aeruginosa, klebseilla pneumoniae and Proteus vulgaris) was evaluated. Methanol extract at the concen...
