Isolation and characterization of Micromonospora phage PhiHAU8 and development into a phasmid.
نویسندگان
چکیده
PhiHAU8, a temperate Micromonospora phage, which is capable of infecting Micromonospora sp. strains 40027 and A-M-01, was isolated. The PhiHAU8 virion has a polyhedral head and a flexible tail and has a small genome (ca. 42.5 kb) with double-stranded DNA and cohesive ends. PhiHAU8 was most stable at 4 degrees C in Difco nutrient broth within a pH range of 6 to 12. PhiHAU8 plaque formation on Micromonospora sp. strain 40027 was optimal with 32 mM Ca(2+) and 30 mM Mg(2+). A lysogen, LXH8, was isolated from turbid plaques, and a phasmid derivative that functions as a lambda cosmid vector in Escherichia coli and as a phage in Micromonospora sp. strain 40027 was constructed. Pulsed-field gel electrophoresis of AseI-digested total DNA showed that PhiHAU8 DNA integrates into the 500-kb AseI fragment of Micromonospora sp. strain 40027.

Tumor necrosis factor alpha (TNF-α) expression amplifies to excess amounts in several disorders such as rheumatoid arthritis and psoriasis. Although, Anti-TNF biologics have revolutionized the treatment of these autoimmune diseases, formation of anti-drug antibodies (ADA) has dramatically affected their use. The next generation antibodies (e.g. Fab, scFv) have not only reduced resulted immunoge...

متن کاملIsolation and Characterization of Lytic Bacteriophages from Wastewater against Listeria monocytogenes
Background and Aims: In the current study, two bacteriophages were isolated from the wastewater sources and characterized by lytic activity against the Listeria monocytogenes (L. monocytogenes) bacterium. Materials and Methods: 50 wastewater samples were collected from the disposal sites. The phages were isolated from the treated samples using the double agar overlay method with L. monocytoge...
