Replication of coliphage lambda DNA [PDF]

open access: yesFEMS 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.

Mathematical model of interaction Escherichia coli and Coliphages

open access: yesMathematical Biosciences and Engineering, 2023
We propose a mathematical model based in ordinary differential equations between bacterial pathogen and Bacteriophages to describe the infection dynamics of these populations, for which we use a nonlinear function with an inhibitory effect.

Coliphages as Indicators of Fecal Contamination in Wastewater Treatment (SCA.Re.S. Project)

open access: yesMedical Sciences Forum, 2021
Bacteriophages are fecal indicators of viral contamination, because they are more similar to human pathogenic viruses than the traditional fecal indicator bacteria, in terms of log-reduction during wastewater treatment and persistence in the aquatic ...

New insights into the biodiversity of coliphages in the intestine of poultry

open access: yesScientific Reports, 2020
Despite phages’ ubiquitous presence and great importance in shaping microbial communities, little is known about the diversity of specific phages in different ecological niches.

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

open access: yesCurrent 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.

Bluephage, a method for efficient detection of somatic coliphages in one hundred milliliter water samples

open access: yesScientific Reports, 2020
Emerging water quality guidelines and regulations require the absence of somatic coliphages in 100 mL of water, yet the efficiency of standardized methods to test this volume of sample is questionable.

Considerations for determining the performance of ultraviolet light emitting diode fluid disinfection systems

open access: yesWater Environment Research, Volume 95, Issue 11, November 2023., 2023
The International Ultraviolet Association Task Force developed guidelines regarding important factors in testing and reporting on performance of UV LED water disinfection systems so that claims could be better understood and benchmarked in rapidly developing markets.

Modeling the photoinactivation and transport of somatic and F-specific coliphages at a Great Lakes beach.

open access: yesJournal of Environmental Quality, 2020
Fecal indicator organisms (FIOs), such as Escherichia coli and enterococci, are often used as surrogates of contamination in the context of beach management; however, bacteriophages may be more reliable indicators than FIO due to their similarity to ...

Comparison of UV‐Cl and UV‐H2O2 advanced oxidation processes in the degradation of contaminants from water and wastewater: A review

open access: yesWater and Environment Journal, Volume 37, Issue 4, Page 633-643, November 2023., 2023
Abstract Applications of advanced oxidation processes (AOPs) in water and wastewater treatment have been the subject of growing interest throughout the last decade. Although UV/hydrogen peroxide (UV‐H2O2) is the most established technology among the UV‐AOPs, UV‐chlorine (UV‐Cl) is emerging as a reliable and potentially more cost‐effective alternative ...

Microbiological hazards associated with the use of water in the post‐harvest handling and processing operations of fresh and frozen fruits, vegetables and herbs (ffFVHs). Part 1 (outbreak data analysis, literature review and stakeholder questionnaire)

open access: yesEFSA Journal, Volume 21, Issue 11, November 2023., 2023
Abstract The contamination of water used in post‐harvest handling and processing operations of fresh and frozen fruit, vegetables and herbs (ffFVHs) is a global concern. The most relevant microbial hazards associated with this water are: Listeria monocytogenes, Salmonella spp., human pathogenic Escherichia coli and enteric viruses, which have been ...
