Din+ ('invertase') activity in Gram-negative bacteria

Blood Group Activity of Gram-negative Bacteria

Distribution of blood group A, B, and H(O) activities among 282 aerobic Gram-negative bacteria, many isolated from the blood of patients, has been studied. Almost half of these bacteria were found to be blood group active. About 10 per cent of the organisms exhibited high, disproportional activities, which in some instances approached those of crude human blood group mucoids. No significant, sp...

In Vitro Antibacterial Activity of Several Plant Extracts and Oils against Some Gram-Negative Bacteria

Background: Medicinal plants are considered new resources for producing agents that could act as alternatives to antibiotics in the treatment of antibiotic-resistant bacteria. The aim of this study was to evaluate the antibacterial activity of 28 plant extracts and oils against four Gram-negative bacterial species.Methods: Experimental, in vitro, evaluation of the activities of 28 plant extract...

Antibiotic Resistance Pattern of Gram-Negative Bacteria in Gorgan

Abstract Background and Objective: The excessive use of broad-spectrum antibiotics will lead to drug resistance of microorganism and specially nosocomial organisms. Because of high incidence of antibiotic resistance in hospitals, we aimed to study antibiotic resistance to gram negative bacteria. Material and Methods: This cross-sectional study was conducted on the data of biological sampl...

Cell Envelope Structure and Functions in Gram-negative Bacteria

In Vitro Antibacterial Activity of Clove against Gram Negative Bacteria

A study was carried out to investigate the potential of using aqueous infusion, decoction and essential oil of clove (Syzygium aromaticum) as natural antibacterial agents against 100 isolates belonging to 10 different species of Gram –ve bacilli viz., Escherichia coli (36), Proteus mirabilis (6), Pseudomonas aeruginosa (10), Enterobacter aerogenes (5), Klebsiella ozaenae (2), Klebsiella pneumon...
