Molecular Typing of Somatic Coliphage Groups and Their Occurrence and Survival in Sewage

Applied Microbiology
A conventional, group-specific PCR method was developed to identify each of the four previously defined major taxa (Myoviridae, Siphoviridae, Podoviridae and Microviridae) of somatic coliphages and used to classify isolates from sewage. Somatic coliphage

TIGHT REPRESSION OF ELASTASE STRAIN K OVEREXPRESSION BY PT7 (A1/O4/O3) SHUTTLE EXPRESSION SYSTEM [PDF]

Science Heritage Journal, 2017
The PT7(A1/O4/O3) is a promoter resulted from construction of O3 and O4 operators into PA1, a promoter derived from coliphage T7, that evidenced lower the occupancy of the promoter by RNA polymerase and thereby increases the repression factor.

Redefining the bacteriophage mv4 site‐specific recombination system and the sequence specificity of its attB and core‐attP sites

Molecular Microbiology, Volume 121, Issue 6, Page 1200-1216, June 2024.
While hundreds of mobile genetic elements utilising tyrosine recombinases (YRs) for integration and excision from bacterial genomes have been identified in databases, less than a dozen have been described in detail. Using in vitro recombination of randomized DNA libraries and high‐throughput sequencing analyses, we have characterised the recombination ...

ISOLATION AND IDENTIFICATION OF COLIPHAGE FROM UNTREATED WASTEWATER IN KUALA PILAH NEGERI SEMBILAN

Journal of Academia
Bacteriophages are viruses that can only infect bacterial cells and are perceptible in almost all places where living bacteria are found, as they are highly host specific.

Endemic bacteriophages: a cautionary tale for evaluation of bacteriophage therapy and other interventions for infection control in animals

Virology Journal, 2012
Background One of the most effective targets for control of zoonotic foodborne pathogens in the farm to fork continuum is their elimination in food animals destined for market.

Engineering strategies and challenges of endolysin as an antibacterial agent against Gram‐negative bacteria

Microbial Biotechnology, Volume 17, Issue 4, April 2024.
Bacteriophage endolysins have limited use against Gram‐negative bacteria for the envelop. To enhance the extracellular activity of endolysin and facilitate its crossing through the outer membrane of Gram‐negative bacteria, researchers have adopted physical, chemical, and molecular strategies for endolysin modification, to promote the application of ...

Development of Coliphage N4: Ultrastructural Studies [PDF]

Journal of Virology, 1974
The basic properties of bacteriophage N4 development have been investigated in Escherichia coli Hfr 3300 under one-step growth and high cell density conditions. N4 r + -infected bacteria are lysis inhibited in mass culture, burst asynchronously starting 180 min postinfection, and ...

The genome and proteome of a virulent Escherichia coli O157:H7 bacteriophage closely resembling Salmonella phage Felix O1

Virology Journal, 2009
Based upon whole genome and proteome analysis, Escherichia coli O157:H7-specific bacteriophage (phage) wV8 belongs to the new myoviral genus, "the Felix O1-like viruses" along with Salmonella phage Felix O1 and Erwinia amylovora phage φEa21-4. The genome

Decay of Enterococcus faecalis, Vibrio cholerae and MS2 Coliphage in a Laboratory Mesocosm Under Brackish Beach Conditions

Frontiers in Public Health, 2019
Enterococci are fecal indicator bacteria (FIB) used for monitoring the microbial quality of bathing water. However, the reliability of health protection by monitoring FIB is questioned.
