Characterization of a Coliphage AS1 isolated from sewage effluent in Pakistan

open access: yesBrazilian Journal of Biology, 2021
The emergence of multi-drug resistant (MDR) bacterial strains, which are posing a global health threat has developed the interest of scientists to use bacteriophages instead of conventional antibiotics therapy.

Airborne coliphages from wastewater treatment facilities [PDF]

open access: yesApplied and Environmental Microbiology, 1976
The emission (from wastewater treatment plants) of airborne coliphages that form plaques on two strains of Escherichia coli was investigated. Two activated-sludge and two trickling-filter plants were studied. Field sampling procedures used large-volume air samplers with recirculation devices.

Decay of infectious adenovirus and coliphages in freshwater habitats is differentially affected by ambient sunlight and the presence of indigenous protozoa communities

open access: yesVirology Journal, 2020
Background Sanitary quality of recreational waters worldwide is assessed using fecal indicator bacteria (FIB), such as Escherichia coli and enterococci. However, fate and transport characteristics of FIB in aquatic habitats can differ from those of viral

Coliphages as indicators of enteroviruses [PDF]

open access: yesApplied and Environmental Microbiology, 1984
Coliphages were monitored in conjunction with indicator bacteria and enteroviruses in a drinking-water plant modified to reduce trihalomethane production. Coliphages could be detected in the source water by direct inoculation, and sufficient coliphages were detected in enterovirus concentrates to permit following the coliphage levels through different ...

Structural basis of transcription arrest by coliphage HK022 Nun in an Escherichia coli RNA polymerase elongation complex

open access: yeseLife, 2017
Coliphage HK022 Nun blocks superinfection by coliphage λ by stalling RNA polymerase (RNAP) translocation specifically on λ DNA. To provide a structural framework to understand how Nun blocks RNAP translocation, we determined structures of Escherichia ...

Report of the Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN) on the effects of climate change on the risk of transmission of foodborne pathogens

open access: yesFood Risk Assess Europe, Volume 3, Issue 3, July 2025.
Abstract The Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN) has carried out an updated review of the scientific evidence on the influence of climate change on the transmission of foodborne pathogens. This global phenomenon represents an emerging threat to food safety and public health, since alterations in weather ...

Microbial reductions and physical characterization of chitosan flocs when using chitosan acetate as a cloth filter aid in water treatment

open access: yesPLoS ONE, 2022
The World Health Organization (WHO) estimates 2.1 billion people lack access to safely managed water. Cloth filtration is often employed in rural and developing communities of South Asia for point-of-use water treatment, but bacteria and viruses are too ...

Characterization and complete genome analysis of a bacteriophage vB_EcoM_DE7 infecting donkey-derived Escherichia coli

open access: yesVirus Research, 2022
A lytic bacteriophage vB_EcoM_DE7 (hereafter designated DE7) that could infect donkey-derived Escherichia coli was isolated. The bacteriophage was examined by transmission electron microscopy, and the result showed that DE7 belonged to the family ...

Reverse genetics in the Arabidopsis chloroplast genome identifies rps16 as a transcribed pseudogene

open access: yesThe Plant Journal, Volume 122, Issue 3, May 2025.
SUMMARY The plastid (chloroplast) genomes of seed plants contain a conserved set of ribosomal protein genes. The rps16 gene represents an exception: It has been lost from the plastid genomes of gymnosperms and several lineages of angiosperms, and may have undergone pseudogenization in a few other lineages, including members of the Brassicaceae family ...

Coliphage HK243: Biological and Physicochemical Characteristics [PDF]

open access: yesMicrobiology and Immunology, 1980
AbstractColiphage HK243 can form plaques on Escherichia coli C and K‐12, but not B. The plaques are 1–2 mm in diameter and are opaque areas which clear upon exposure to chloroform vapor. During one‐step growth, the eclipse and the latent periods are 20 and 30 min, respectively. Phage‐infected cells continue to produce cell‐free plaque‐forming units for
