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

open access: yesFrontiers 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.

Codon contexts in enterobacterial and coliphage genes. [PDF]

open access: yesMolecular Biology and Evolution, 1987
This investigation of the codon context of enterobacteria, plasmid, and phage protein genes was based on a search for correlations between the presence of one base type at codon position III and the presence of another base type at some other position in adjacent codons.

Defining the SOS Operon of Coliphage 186

open access: yesVirology, 1996
We have sequenced the LexA-controlled operon of coliphage 186 that carries the tum gene, whose product is necessary for UV induction of the 186 prophage. The operon consists of orf95 and orf97, and we have identified orf95 as the tum gene. The major translation products from orf95 result from internal initiations and modulate Tum activity.

Recovery of somatic coliphages in shellfish

open access: yesWater Science and Technology, 1995
A phage recovery technique is described that is shown to be easy to perform and sensitive. It is efficient in detecting somatic coliphages in mussels artificially contaminated, even at very low levels. Good results are also reported for detection and enumeration of naturally occurring coliphages in mussels and cockles from the French Atlantic coast.

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 ...

Trimethoprim: An Old Antibacterial Drug as a Template to Search for New Targets. Synthesis, Biological Activity and Molecular Modeling Study of Novel Trimethoprim Analogs

open access: yesMolecules, 2019
A new series of trimethoprim (TMP) analogs containing amide bonds (1−6) have been synthesized. Molecular docking, as well as dihydrofolate reductase (DHFR) inhibition assay were used to confirm their affinity to bind dihydrofolate reductase enzyme.
