دراسة مناعية ونسيجية لمرضى التهاب الزائدة الدودية الحاد

The objective of this research is to find a natural chemical compounds alternative available and free of side effects and high-impact effective against many bacterial species. The crude ethanol extracts of Phoenix dactylifera leaves were tested for antibacterial action against bacterial isolates, the ethanol extracts showed good antibacterial activity against all isolates Enterobacter sp., Salmonella sp., Pseudomonas aeruginosa Escherichia coli, Staphylococcus aureus, Klebsella pneumonia, Streptococcus pneumoniae, and Protus sp. bacterial isolates which had shown zone of inhibition against all plant extracts concentration with exceptions at 25 mg/ml concentration related with Salmonella sp., Pseudomonas aeruginosa, Escherichia coli and Protus sp., also the largest inhibition zone were revealed at 100 mg/ml concentration especially with Escherichia coli and Streptococcus pneumoniae isolate while Salmonella sp. isolate exhibited the smallest inhibition zone under 50mg/ml concentration.

Antibacterial activity of husk of Cocos nucifera Linn alcoholic extract against Methicillin Resistance Staphylococcus Aureus (MRSA) was isolated from 9 volunteers and verified by VITEK. However, 3 volunteers samples were deemed to be non-MRSA. Fibrous husks of Cocos nucifera were powered extracted in 70% ethanol. For comparison with extract, antibiotic disks were spread on agar for Gentamicine, Tetracycline, Cefotaxime, Ceftriaxone, Ampicilin, Oxacilin, Chloramphenicol, Clavulanate and Amoxicillin (AMX) minimum inhibitory concentrations. We found extract exhibited effective MIC and MBC at 100 and 50 mg/ml for all discs.
