Airborne coliphages from wastewater treatment facilities [PDF]

Applied 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.

Coliphages as indicators of enteroviruses [PDF]

Applied 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 ...

Antimicrobial Resistance in Escherichia coli and Resistance Genes in Coliphages from a Small Animal Clinic and in a Patient Dog with Chronic Urinary Tract Infection

Antibiotics, 2020
Antimicrobial resistance is on the rise in certain pathogens that infect pets and their owners. This has raised concerns about the use of antibiotics and the transfer of resistance elements in small animal clinics.

The Effect of UV and Combined Chlorine/UV Treatment on Coliphages in Drinking Water Disinfection

, 2016
Ultraviolet (UV) irradiation is a common way to disinfect drinking water, but some viruses are very resistant to UV. Drinking water was disinfected with UV after spiking with MS2 and 18 different coliphages isolated from municipal wastewater effluent. In

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

Food 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 ...

In Vitro and In Vivo Assessment of the Potential of Escherichia coli Phages to Treat Infections and Survive Gastric Conditions

Microorganisms, 2021
Enterotoxigenic Escherichia coli (ETEC) and Shigella ssp. infections are associated with high rates of mortality, especially in infants in developing countries.

Coliphage HK243: Biological and Physicochemical Characteristics [PDF]

Microbiology 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

Persistence of F-Specific RNA Coliphages in Surface Waters from a Produce Production Region along the Central Coast of California

PLoS ONE, 2016
F+ RNA coliphages (FRNA) are used to source-track fecal contamination and as surrogates for enteric pathogen persistence in the environment. However, the environmental persistence of FRNA is not clearly understood and necessitates the evaluation of the ...

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

The 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 ...

Evaluation of the Ratio of Spot Tests and Plaque-Forming Activity Tests of Bacteriophages of Prevalent Pathogens

Эпидемиология и вакцинопрофилактика
Relevance. Obtaining clean lysis spots, with tolerable presence of individual colonies of secondary growth, in spot tests is a criterion for assessing the effectiveness of therapeutic bacteriophages.
