Replication of coliphage lambda DNA [PDF]

FEMS Microbiology Reviews, 1995
A general scheme of lambda phage and plasmid DNA replication in Escherichia coli is presented, and results of in vivo experiments from the authors' laboratory are superimposed. The initiator lambda O functions in the assembly of the replication complex (RC) at ori lambda, making it a stable component of this structure.

Occurrence of coliphage in effluent: A systematic literature review and meta-analysis

Hygiene and Environmental Health Advances, 2022
Studies have illustrated that wastewater treatment methods targeting bacteria do not remove all types of viruses and available epidemiological studies indicate bacteria concentrations may not always be predictive of viral illnesses associated with ...

Plant Sample Collection and Shipment for Multi‐omic Analyses and Phytosanitary Evaluation

Current Protocols, Volume 3, Issue 12, December 2023., 2023
Abstract Plant sample preparation for analyses is a fundamental step in high‐throughput omics strategies. Especially for plant metabolomics, quenching of hydrolytic enzymes able to affect metabolite concentrations is crucial for the accuracy of results.

Morphological Variants of Coliphage P1 [PDF]

Journal of Virology, 1970
Lysates of P1 from all hosts tested contained at least three morphological variants with respect to head size. These were termed “big” (P1B), “small” (P1S), and “minute” (P1M). Since successive clonings of plaques isolated on many different hosts failed to change the proportions of the variants, we concluded that the production of variants

Assessment of Potential Efficacy of Coliphage Therapy on Multidrug Resistant Clinical Isolates of Escherichia coli

UMYU Journal of Microbiology Research, 2020
Coliphages are the bacteriophages that attack and lyse Escherichia coli, a bacterium emerging as multidrug-resistant, thereby posing a serious public health challenge.

Fluence requirements in existing UV disinfection facilities to comply with EU validation performance targets for reclaimed water: a case study

Water Science and Technology, 2023
Since 2020, there is a new European Regulation (EU, 2020/741) on minimum requirements for water reuse, where routine and validation monitoring requirements (log reductions of indicator microorganisms and reference pathogens) have been established.

Sequence Variability of P2-Like Prophage Genomes Carrying the Cytolethal Distending Toxin V Operon in Escherichia coli O157 [PDF]

, 2013
Cytolethal distending toxins (CDT) are potent cytotoxins of several Gram-negative pathogenic bacteria, including Escherichia coli, in which five types (CDT-I to CDT-V) have been identified so far.
