Virus Quotes

“We must act now to prevent further spread of EBOLA VIRUS. If we do not act collectively, EBOLA VIRUS will wipe all whole populations and generations into their grave. The call to action is now.”

“This year, 1996, has been designated the 'Year of the Vaccine,' commemorating the 200th anniversary of Edward Jenner's vaccination of James Phipps with cowpox virus and subsequent challenge with smallpox virus. Insight into the nature of viruses, and how viruses interact with mammalian cells, has evolved since the turn of the century.”

“...on opening the incubator I experienced one of those rare moments of intense emotion which reward the research worker for all his pains: at first glance I saw that the broth culture, which the night before had been very turbid was perfectly clear: all the bacteria had vanished... as for my agar spread it was devoid of all growth and what caused my emotion was that in a flash I understood: what causes my spots was in fact an invisible microbe, a filterable virus, but a virus parasitic on bacteria. Another thought came to me also, If this is true, the same thing will have probably occurred in the sick man. In his intestine, as in my test-tube, the dysentery bacilli will have dissolved away under the action of their parasite. He should now be cured.”

“If Charles Darwin reappeared today, he might be surprised to learn that humans are descended from viruses as well as from apes.”

“The researchers looked deeper into these observations, in hopes of gaining insight into the mechanisms underlying the high evolutionary rate and extraordinary immunologic plasticity of influenza HA. They probed in more detail the precise codons that are used by the virus to encode the influenza HA1 protein. The discriminated between codons on the basis of volatility. Each three-nucleotide codon is related by a single nucleotide change to nine 'mutational neighbours.' Of those nine mutations, some proportion change the codon to a synonymous codon and some change it to a nonsynonymous one, which directs the incorporation of a different amino acid into the protein. More volatile codons are those for which a larger proportion of those nine mutational neighbours encode an amino acid change. The use of particular codons in a gene at a frequency that is disproportionate to their random selection for encoding a chosen amino acid is termed codon bias. Such bias is common and is influenced by many factors, but here the collaborators found strong evidence for codon bias that was particular for and restricted to the amino acids making up the HA1 epitopes. Remarkably, they observed that influenza employs a disproportionate number of volatile codons in its epitope-coding sequences. There was a bias for the use of codons that had the fewest synonymous mutational neighbours. In other words, influenza HA1 appears to have optimized the speed with which it can change amino acids in its epitopes. Amino acid changes can arise from fewer mutational events. The antibody combining regions are optimized to use codons that have a greater likelihood to undergo nonsynonymous single nucleotide substitutions : they are optimized for rapid evolution.”

“Fear, left unchecked, can spread like a virus.”

“Destructive force of hatred is a virus”

“Democracy is a continuous, open process of civility.A democracy can never be “done”; updating democracy can never be over.Democracy can be nothing else but a continuous process, because we use it to organize our life, and life is nothing but a continuous process.Democracy can be compared to an operating system or an anti-virus software; if it does not get perpetually updated, it becomes obsolete very fast.Trusting the updates or the “improvements” of democracy to the elected and the owned mass media is like trusting the updates of an anti-virus program to virus creators; it defeats the purpose of updates or improvements.”

“There is nothing so patient, in this world or any other, as a virus searching for a host.”
