چکیده

The phage enzymes can lyse the host in which they resides, but it is not yet known whether they show any effect on the non-susceptible hosts on solid media (Consortia). It is observed during our studies that the consortial lawn on the solid medium shows clear plaques irrespective of their specificity to the inoculated phages. The consortial studies indicate the combined application of phage enzymes for controlling pathogenic organisms. Our experiment thus proves the non-specificity of phage enzymes towards host cell components and states that the activity of phage enzymes is totally substrate (cell wall components) specific and is independent of host type.

Recombinant scFv Antibodies against P30 Surface Protein of Toxoplasma Gondii

Background & Aims: Toxoplasma gondii is an obligate, intracellular parasite, which is widely spread in the world. The parasite is able to infect all warm-blooded hosts including humans and farm animals. The infection in humans often occurs after the ingestion of raw or undercooked meat containing tissue cysts. Several methods have been applied to detect this parasite in contaminated foods. Reco...

Escherichia coli O157:H7 bacteriophage Φ241 isolated from an industrial cucumber fermentation at high acidity and salinity

A novel phage, Φ241, specific for Escherichia coli O157:H7 was isolated from an industrial cucumber fermentation where both acidity (pH ≤ 3.7) and salinity (≥5% NaCl) were high. The phage belongs to the Myoviridae family. Its latent period was 15 min and average burst size was 53 phage particles per infected cell. The phage was able to lyse 48 E. coli O157:H7 strains, but none of the 18 non-O15...

A non-canonical multisubunit RNA polymerase encoded by a giant bacteriophage

The infection of Pseudomonas aeruginosa by the giant bacteriophage phiKZ is resistant to host RNA polymerase (RNAP) inhibitor rifampicin. phiKZ encodes two sets of polypeptides that are distantly related to fragments of the two largest subunits of cellular multisubunit RNAPs. Polypeptides of one set are encoded by middle phage genes and are found in the phiKZ virions. Polypeptides of the second...

Development of small designer aldolase enzymes: catalytic activity, folding, and substrate specificity.

Small (24-35 amino acid residues) peptides that catalyze carbon-carbon bond transformations including aldol, retro-aldol, and Michael reactions in aqueous buffer via an enamine mechanism have been developed. Peptide phage libraries were created by appending six randomized amino acid residues to the C-terminus or to the N-terminus of an 18-mer alpha-helix peptide containing lysine residues. Reac...

Staphylococcal Virolysin, a Phage-induced Lysin

Virolysin is a lysin which appears in Staphylococcus aureus K(1) cells infected with phage P(14); together with phage, virolysin is released from phage-infected cells at the time of lysis. Autolysin is a lysin formed by uninfected cells of the K(1) strain; autolysin is released from uninfected cells by autolysis. They show the following similarities: Both agents act within the genus Micrococcus...
