The growth of bacteriophage [PDF]

open access: yes, 1939
1. An anti-Escherichia coli phage has been isolated and its behavior studied. 2. A plaque counting method for this phage is described, and shown to give a number of plaques which is proportional to the phage concentration.

Plaque Assay for Ebola Virus [PDF]

open access: yesJournal of Clinical Microbiology, 1981
A plaque assay for Ebola virus is reported. The procedure has real potential for future research, although it is less sensitive than indirect fluorescent-antibody and mouse inoculation tests.

Differential Effects of Lipid-lowering Drugs in Modulating Morphology of Cholesterol Particles. [PDF]

open access: yes, 2017
Treatment of dyslipidemia patients with lipid-lowering drugs leads to a significant reduction in low-density lipoproteins (LDL) level and a low to moderate level of increase in high-density lipoprotein (HDL) cholesterol in plasma.

Passaging of a Newcastle disease virus pigeon variant in chickens results in selection of viruses with mutations in the polymerase complex enhancing virus replication and virulence [PDF]

open access: yes, 2010
Some Newcastle disease virus (NDV) variants isolated from pigeons (pigeon paramyxovirus type 1; PPMV-1) do not show their full virulence potential for domestic chickens but may become virulent upon spread in these animals.

Efficient Selection of Recombinant Fluorescent Vaccinia Virus Strains and Rapid Virus Titer Determination by Using a Multi-Well Plate Imaging System

open access: yesBiomedicines, 2021
Engineered vaccinia virus (VACV) strains are used extensively as vectors for the development of novel cancer vaccines and cancer therapeutics. In this study, we describe for the first time a high-throughput approach for both fluorescent rVACV generation ...

Coronaviridae and SARS-associated Coronavirus Strain HSR1

open access: yesEmerging Infectious Diseases, 2004
During the recent severe acute respiratory (SARS) outbreak, the etiologic agent was identified as a new coronavirus (CoV). We have isolated a SARS-associated CoV (SARS-CoV) strain by injecting Vero cells with a sputum specimen from an Italian patient ...
