The present study was aimed to evaluate the antibacterial activity of Amorphophallus campanulatus (family: Araceae) commonly known as jangli suran. The root, stem and leaf of A. campanulatus, extracted successively with polar (aqueous, methanol), dipolar (acetone) and non polar (chloroform) solvents, yielded more phyto compounds in case of root followed by stem and leaf. The extracts were asses...
Five techniques for Gram staining bacteria in paraffin sections were compared on serial sections of pulmonary tissues from eight bacteriological necropsies. Brown and Hopp's method was the most satisfactory for distinguishing Gram-positive and Gram-negative bacteria. However, this method cannot be recommended as the preparations were frequently overstained, and the Gram-negative bacteria were s...
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...
background: recent analyses of hospital outbreaks have documented the spread of resistance to imipenem, which is currently a major problem among gram positive and gram-negative bacteria. the aim of this study was to describe the rate of gram- positive and gram-negative isolates resistance to imipenem as an antibiotic. methods: recorded files of 242 hospitalized patients with at least one sampl...
objective: due to the alarming increase the incidence and prevalence of infectious diseases and increasing bacterial resistance to antibiotics need to discover new strong antimicrobial compounds is feeling.methods: in this study, the antimicrobial properties of spider silk pholcus phalangioides produced in sterile conditions against two bacteria, listeria monocytogenes and esherichia coli with ...
A wide range of medicinal plant parts that possess varied medicinal properties are used for extracts as raw drugs. In this study, the ethanolic extract obtained from aerial parts of fennel (Foeniculum vulgare Mill.) seedlings was evaluated in vitro to examine their antimicrobial activity against four Gram-negative and three Gram-positive bacteria and two fungi. Aerial parts of one-month-old see...
