Here is an interesting article regarding the isolation of viruses from a totally different branch of virology, far from the nefarious influence of the medical death cult.
Methods for the isolation of viruses from environmental samples, pubmed, pdf. This is a chapter from "Bacteriophages: Methods and Protocols, Volume 1: Isolation, Characterization, and Interactions" (2009).
There is also a similar paper by the same authors: Sampling natural viral communities from soil for culture-independent analyses. pdf
Indeed, this earlier article has the very important point in its title - culture-independent analyses.
This whole area of research can be classed as microbial ecology - the vast numbers of bacteria and viruses that exist everywhere - and, unlike their "medical" brethren, these scientists want to identify each microbe in its pure state, unmolested by being thrown into a soup of other cells.
The first accurate direct counts of viruses in water samples revealed that viruses are the most abundant microorganisms on Earth. With abundances ranging from 104 to 108 viruses/ml, viruses typically outnumber co-occurring bacterial cells by 10-fold in most aquatic environments. [...] Within the small sample set of soils examined to date, viral abundance ranges from high 108 to mid 109 viruses per gram dry weight of soil with highest abundance occurring in wetter forested soils and lower abundances in intensively managed agricultural soils.
These figures are quite recent and with a global estimate of about 1031 this makes viruses the most abundant microrganisms on the planet. They are everywhere and "viruses represent the largest reservoir of unknown genetic diversity on Earth."
Because the ideal objective of synecological (ecological relationship) studies is to assay all members of a community with equal efficiency, methods are chosen which minimize both artifactual bias in the concentration of viruses and provide a sample devoid of contaminants that can interfere with microscopy or molecular genetic assays.
To make this absolutely clear, the isolation methods promoted by the medical cartels are not used precisely because they contaminate the viruses! You cannot classify a virus after it has gone through a culture that may change its genetic profile. By having viruses replicate within a cell culture will change those viruses. This is at the heart of the debate over "isolation". Many countries have admitted, in writing, that they have no proof of an isolated virus using non-cultured techniques and yet, in the same breath, champion the genetic sequences from a plethora of contaminated sources into a chimera that exists only in computers.
The most virulent virus remains a mental one - and at 109 minds per planet has reached criticality.
