we consider of the antimicrobial activity on the ag nanoparticles(ag nps) aqueous solutions, which was prepared using a stabilizer, such as poly(n vinyl 2 pyrrolidone pvp , for staphylococcus aureus) s aureus and escherichia coli e coli by measuring the minimum inhibitory concentration mic . antimicrobial effect of ag nps for s aureus and e coli was investigated using disk diffusion method also...

Purified natural (n) and recombinant (r) murine (mu) mast cell growth factor (MGF, a c-kit ligand) were evaluated alone and in combination with r human (hu) erythropoietin (Epo), rhu granulocyte-macrophage colony-stimulating factor (rhuGM-CSF), rhuG-CSF, and/or rhuM-CSF for effects in vitro on colony formation by multipotential (colony-forming unit-granulocyte, erythroid, monocyte, megakaryocyt...

Studies on the mechanism of anemia in mice of genotype 51151d have implicated the hematopoietic stroma (the hematopoietic inductive microenvironment, HIM) rather than hematopoietic stem cells as the site of the defect. Using methylcellulose-supported bone marrow culture systems, we have observed, in addition to classical hematopoietic colonies, the formation of surface associated fibroblastic p...

Bacteriophages isolated from free-range chickens were tested as a therapeutic agent for reducing the concentration of Salmonella enterica serovar Enteritidis phage type 4 (S. Enteritidis PT4) in caeca of broilers. One-day-old broilers infected with S. Enteritidis PT4 by a seeder bird method were orally treated on the seventh day of age with a mixture of 10(11) plaque-forming units of each of th...

Thirty clinical isolates of Staphylococcus aureus were tested for tolerance to oxacillin, cephalothin, and gentamicin by using killing curves and broth dilution susceptibility tests. Tolerance was defined as the presence of>/=100 colony-forming units per ml remaining after 24 h of incubation of the killing curve suspensions. Nineteen of 30 isolates were tolerant to oxacillin and cephalothin, bu...

The toxicity of intrapleural Tice strain Bacillus Calmette-Guérin (BCG) infection was tested in hamsters. Doses above 10(6) colony-forming units caused significant systemic infection, which could be controlled with conventional antituberculosis therapy. Living BCG in the pleural space did not prevent the healing of bronchial or vascular closures after pulmonary resection. Prophylactic intrapleu...

Probiotics are microorganisms with potential health benefits. They may be used to prevent and treat antibiotic-associated diarrhea and acute infectious diarrhea. They may also be effective in relieving symptoms of irritable bowel syndrome, and in treating atopic dermatitis in children. Species commonly used include Lactobacillus sp., Bifidobacterium sp., Streptococcus thermophilus, and Saccharo...

A total of 20 patients with symptomatic urinary tract infections (greater than 10(5) colony-forming units of Escherichia coli per ml of urine in addition to pyuria) received 10 mg of ampicillin and 2 liters of fluid daily for 3 days. After 2 days, 16 patients had culture-negative urine without pyuria. A total of 18 similar patients received only 2 liters of fluid for 3 days. On day 4, all had g...

Background & Aims: Nanosilver-based paint is a new technology with antimicrobial and antifungal characteristics. These characteristics were investigated in this study with regard to fungal contamination in hospitals. Method: Regarding hospitalization of transplant patients and their sensitivity to hospital infections, two similar rooms were selected in nephrology ward. One of them was paint...

The growth requirements of 135 clinical isolates of Neisseria gonorrhoeae and six American Type Culture Collection reference strains were examined by using a simple chemically defined medium known as Wong-Shockley-Johnston medium, WSJM. The simple liquid medium supported growth of gonococci from an inoculum of 2 X 10(6) colony-forming units ml-1 and yielded 10(10) colony-forming units ml-1 in 1...
