Thirty samples were collected from patients (١٠-٤٥) years old, suffered from tonsillitis,pharyngitis, infected wounds, acne & Bronchitis. Gram -positive bacteria were isolated from these samples, and diagnosed, of which, Staphylococcus aureus ( ٥٠%) and Staphylococcus epidermidis (١٦.٦٦%), Streptococcus pyogenes (١٣.٣٤%), Streptococcus pneumoniae (١٠%) and Micrococcus spp (١٠%). Alcoholic and water extracts of the punica granatum(Pomegranate) peels as well as the dried powders were prepared, the effect of these extracts were studied against these isolates. The antimicrobial susceptibility tests of the extracts were determined by Kirby-Bauer method and the MICs were determined. The antibacterial activity of punica granatum(Pomegranate) peels was determined. The alcoholic extract showed more potent inhibitory effect on the isolates than water extract, and the best effect was on the growth of Staphylococcus epidermidis followed by Staphylococcus aureus , Micrococcus spp, Streptococcus pyogenes and Streptococcus pneumoniae. The zone of inhibition was (١٧-٢٣mm) for alcoholic extract and( ١٢-٢٣mm) for watery extract. The antibacterial activity of pomegranate peels extracts should make it useful for treatment of wounds, skin infections, tonsillitis and pharyngitis caused by the above bacteria.
Thirty five samples were collected from patients (1-30) years old, suffered from, infected skin , rushes, boils , oral thrush, anal & vaginal itches. Candida albicans 57.3% (20 isolates) and Candida tropicalis 22.5% (8 isolates) Aspergillus fumegatus 11.5% (4 isolates) Aspergillus nigar 8.7%(3 isolates) , were isolated & identified from these samples. Alcoholic & water hot extracts of the punica granatum (Pomegranate) peels as well as the dried powder were prepared. The anti-fungal activity of the extracts was evaluated by means of the agar-well diffusion assay. The extract exhibited potent activity against yeast. The Minimum inhibitory concentrations were 128-1024 μg/ml against Candida albicans and Candida tropicalis .Their was little difference between the activities of alcoholic extract & aqueous extract. These results suggest the Pomegranate Peels extract which contains gallotanic acid as a promising anti-fungal agent. Key wards : Antifungal agents, Plant extracts, Candida isolation
The aim of this study is to evaluate in-vitro activity of Cefamandol (Cfm) and Ceftazidime (Cfz), in combination with Clavulanic acid (CA) against ten complicated multiresistant uropathogenic E.coli .One hundred clinical strains were isolated from patients with chronic urinary tract infections (UTIs), these isolates were identified by the Api identification systems. The antimicrobial susceptibility tests were determined by Kirby-Bauer method, all of them were sensitive to Imipenem (Imp). Ten strains were chosen for the present study, they were resistant to Ampicillin (Amp), Amoxicillin (Amo), Carbenicillin (Cb), Ticarcillin (Tic), Azlocillin (Azl), Amoxicillin\ Potassium Clavulanate {Augmentin(Amc)}, (Amo\CA), Ticarcillin\ Potassium Clavulanate {Timentin} (Tic\CA) ,Cefazolin (Cfo) ,Cefaloridin (Cfr), Cefamandol, (Cfm),Cefoxitin, Ceftazidime (Cfz), Cefixime (Cxm), Cefoperazone( Cfp) and Aztreonam (Atm), also resistant to other antibiotics, Tetracycline(Tc),Cloramphenicol(Cm),Gentamycin(G),Amikacin (Amk), Ciprofloxacin (Cip) and Trimethoprim. 50% of the isolates were resistant to Nalidixic acid and Rifampicin. The minimum inhibitory concentrations of Cefamandol and Ceftazidime were determined, by tube method. Transfer of plasmids were done by direct conjugation test to sensitive standard E.coli ,cell free β- lactamases were prepared and detected by macro-iodometric method. The activity of each cell free ß– lactamases extract against Cfm and Cfz were determined by disks diffusion method (microbiological Masuda method). Excellent activities were obtained against these strains when Cfm and Cfz, combined with CA, therefore complete zones of inhibition were obtained indicated the prevalence of extended spectrum β- lactamases in E.coli. The stability of Cfm and Cfz in the presence of CA were useful in the treatment of chronic urinary tract infections caused by multiresistant β- lactamase (ESBL) producer E.coli. Key words: Extended spectrum β- lactamases, Imipenem, Aztreonam, Ceftazidime.
The aim of this study was to evaluate in-vitro activity of Cefamandol and Ceftazidime, in combination with potassium clavulanate against 10 uropathogenic E.coli isolated from patients with chronic complicated urinary tract infections (UTIs), these isolates were identified by the Api identification systems.The antimicrobial susceptibility tests were determined by Kirby-Bauer method and the minimum inhibitory concentrations of Cefamandol and Ceftazidime, were determined, by tube method. These isolates were resistant to Ampicillin (Amp), Amoxicillin (Amo), Carbenicillin (Cb), Ticarcillin (Tic), Amoxicillin\ Potassium Clavulanate {Augmentin}, (Amo\CA), Ticarcillin\ Potassium Clavulanate {Timentin} (Tic\CA), Cefamandol (Cfm) and Ceftazidime (Cfz), also resistant to other antibiotics, such as Tetracycline, Chloramphenicol, Trimethoprim and (50% of the isolates were resistant to Nalidixic acid and Rifampicin). Transfer of plasmids by direct conjugation experiments were performed by mating 10 strains with recipient strain E.coliK12C 600 Rif or Nal resistant, and cell free b- lactamases were prepared and detected by macro-iodometric method. The activities of each cell free b– lactamases extract against Cfm and Cfz were determined by disks diffusion method (microbiological Masuda method) and by macro-iodometric method. The activity of b- lactamases was inhibited by the addition of Potassium Clavulanate. Conclusion: Good effectiveness of Cfm\ CA and Cfz\ CA was obtained against resistant strains of E.coli due to complicated urinary tract infection (UTIs). Key words: b- lactamases, Cefamandol, Ceftazidime, Timentin and Augmentin .
