Bioactive Effect of Cinnamomum zealynicum bark Extracts on Some Locally Isolated Pathogenic Bacteria
...Show More Authors

A series of experiments were conducted to evaluate the antibacterial effect of Cinnamomum zealynicum bark aqueous , methanol, and chloroform extracts against some gram positive and gram negative pathogenic bacteria which isolated from wound, throat infection, urine and stool during the period from December /2013 to February /2014 from Alkarama hospital in Wasit. All these isolates were identified by using VITEK2 compact system. Antibiotic sensitivity test of the bacterial isolates was determined for ten antibiotics. Chemical analysis showed that Cinnamomum zeylanicum bark extracts contained different active compounds (phenoles, alkaloids, tannins, glycosides, coumarins, saponins, resins flavones and essential oil). The laboratory tests of antibacterial activity , showed that Staphylococcus aureus was the most affected by the extracts under study then followed with Enterococcus faecalis, Streptococcus pneumoniae, Escherichia coli and Klebsiella pneumoniae respectively. Aqueous extract showed highest values in MIC (400 μg/ml) and MBC (450 μg/ml) for S aureus, followed by chloroform (350 μg/ml, MIC and 400 μg/ml, MBC), then methanol (335 μg/ml, MIC and 375 μg/ml MBC) while the lowest values were recorded for K. pneumonia (MIC 175, 200 and 250 μg/ml, and MBC 200, 250 and 300 μg/ml respectively). In other hand inhibition zones appeared at 200 μg/ml for S. aureus and E. faecalis, and at 300 μg/ml for E. coli and S. pneumonia, and at 400 μg/ml for K. pneumoniae for aqueous extract, while methanol extract inhibition zones started from 100 μg/ml for S. aureus, and at 200 μg/ml for S. pneumonia and E. faecalis, and at 300 μg/ml for K. pneumonia and E. coli. Chloroform extract showed inhibition zones for S. pneumonia, E. faecalis and S. aureus at 200 μg/ml and for E coli and K. pneumoniae at 300 μg/ml.

Inhibitory Effect of Bacteriophages Isolated from Sewage Water in the City of Kirkuk on some Types of Human Pathogenic Bacteria
...Show More Authors

Most approaches to combat antibiotic resistant bacteria concentrate on discovering new antibiotics or modifying existing ones. However, one of the most promising alternatives is the use of bacteriophages. This study was focused on the isolation of bacteriophages that are specific to some of commonly human pathogens namely E. coli, Streptococcus pyogenes, Staphylococcus aureus, Proteus mirabilis, Pseudomonas aeruginosa, Salmonella spp. and Klebsiella pneumoniae. These bacteriophages were isolated from sewages that were collected from four different locations in Kirkuk City. Apart from S. pyogenes, bacteriophages specific to all tested bacteria were successfully isolated and tested for their effectiveness by spot test. The most effective

Effect of Extracts from Zygophyllim fabago on Growth of Some Bacteria
...Show More Authors

The present study was carried out to evaluate antibacterial activity of water , alcoholic extracts (cold and hot) and the crude alkaloid extract of leaves, seeds and roots of Zygophyllum fabago plant against the growth of some bacteria including gram negative bacteria(Escherichia coli ,Pseudomonas aeruginosa) and gram positive bacteria(Staphylococcus aureus  ,Bacillus subtilis).        Results showed variation in antibacterial activity of different extracts against the studied bacteria. Hot alcoholic extracts showed the highest antibacterial activity followed by hot water extract. Additionally, alcoholic extracts of seeds revealed a higher activity compared with other plant extract.Results of sensi

Effect of Aquatic, Alcoholic and Oily Extracts of Cocos nucifera L.on the Growth of Certain Pathogenic Bacteria Isolated from Wounds and Burns Infections
...Show More Authors

Three types of extracts ( aquatic, alcoholic, and oily ) were prepared from the fruits of coconuts, and a series of chemical tests were conducted in addition to the use of the FTIR equipment to determine the active locations in the prepared extracts. The results indicated the presence of active compounds (tannins, saponins, flavonoids, turbines and steroids) in the extracts prepared from the fruits of coconuts, also the antimicrobial capability of these extracts were tested on pathogenic bacteria isolated from wounds and burns infections cases. The results proved that the concentration 80 mg/ml of the aquatic extract is the minimum inhibitory concentration for the microbes: Proteus vulgaris and Pseudomonas fluorescence, while the

Antimicrobial Activity of Silver Nanoparticles on Pathogenic Bacteria
...Show More Authors

Nosocomial infection is acquired contamination of hospitals and health care units caused by multidrug resistant bacteria. Currently, bacterial resistance to antimicrobial medication represents a complicated public health problem. Recent studies on the antimicrobial activity of silver nanoparticles (AgNPs) attracted researchers worldwide to focus on the safe synthesis of AgNPs as antimicrobial agents against multidrug resistant bacteria. The antimicrobial efficacy of AgNPs on pathogenic bacteria isolated from clinical cases of acquired hospital infection was targeted in this project. Fifty specimens of stool were collected through private laboratories in Baghdad from patients who suffered diarrheal symptoms. Bacterial isolation, identific
