Effect of Purified Enzymes on Viruses and Gram-negative Bacteria
Evidence is presented that some viruses behave like proteins in that they are inactivated by proteolytic enzymes, whereas others prove more or less resistant. Ten strains of living Gram-negative bacteria resisted the action of purified trypsin and chymotrypsin, while the killed organisms were rapidly digested. Gram-positive bacteria, on the other hand, were resistant whether living or dead. The...
متن کاملdistribution of r-factors in gram negative bacteria
a total number of 259 gram negative bacteria (entero-bacteria) isolated during the years 1973-1974 was examined. these strains were isolated from sick children referred and or hospitalized in a children hospital in tehran. the strains consisted of ; 131e.coli, 52 salmonella, 40 klebsiella, 18 shigella, 13 proteus, 3 enterobacter and 2 citrobacter. sensitivity tests were performed according to t...
متن کاملComparison of the D-glutamate-adding enzymes from selected gram-positive and gram-negative bacteria.
The biochemical properties of the D-glutamate-adding enzymes (MurD) from Escherichia coli, Haemophilus influenzae, Enterococcus faecalis, and Staphylococcus aureus were investigated to detect any differences in the activity of this enzyme between gram-positive and gram-negative bacteria. The genes (murD) that encode these enzymes were cloned into pMAL-c2 fusion vector and overexpressed as malto...
متن کاملAntibiotic 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...
متن کاملIsolation of Gram-negative Bacteria
Three different areas -hospital, food-handling establishments and human dwellings, were surveyed for pathogenic gram-negative bacteria carried on the cuticles of cockroaches. Fifty species of bacteria were identified from all cockroaches. Escherichia coli, Klebsiella pneumoniae, Citrobacter freundii and Enterobacter cloacae were the most frequently found. Pathogenic and potentially pathogenic b...
