in study, spherical silver nanoparticles (snps) were synthesized by chemical reduction method from a metal precursor silver nitrate in presence of an anionic surfactant and strong reducing agent. in this experimental work, snps are synthesized in presence of different concentration of stabilizing agent and effect of stabilizing agent on size distribution of snps have been observed. further anti...

Probes derived from the tufA gene of Escherichia coli have been utilized to detect homologous sequences on Spirulina platensis DNA. A 6-kilobase-pair fragment of S. platensis DNA appears to contain two sequences homologous to the E. coli gene. Thus, as reported for gram-negative bacteria, the cyanobacterium presumably contains two tuf genes.

Introduction: Mastitis is an inflammatory condition of the breast and since it is usually associated with lactation , it is usually called lactational mastitis. Two major causes of mastitis are milk stasis and infection. The aim of this study was to evaluate bacterial mastitis in lactating women and to determine the sensitivity pattern of the involved bacteria. Method: A total of 203 milk sampl...

the presence of antibacterial activity in bovine β-lactoglobulin and in α-lactalbumin hydrolysates was investigated. the plasmin-digest of β-lactoglobulin (pdβ) and of α-lactalbumin (pdα) were fractionated, using reversed phase high performance liquid chromatography. the antibacterial activity of β-lactoglobulin, α-lactalbumin, nisin, plasmin, pdβ and pdα were in vitro tested against pathogenic...
