vira
Language: English
Part of speech: noun
Etymology: From translingual Vira or New Latin vīra.
Senses: examples: text: Seeing, however, that neither virus Ordinary, Tzaneen, nor Bulawayo protected completely against horse-sickness in the various parts of the Transvaal I now decided to make a combination of the two vira and to add to it the third virus, Bulawayo.
ref: 1907, Annual Report of the Director of Agriculture, page 69:
text: Then the idea occurred to unite all these various vira and to obtain in this way a polyvalent virus which would protect against any of the vira of which it was composed, and by this means I hoped to reduce the mortality in practice.
ref: 1909, Report of the Government Veterinary Bacteriologist, page 24:
text: In order to settle the point whether an animal that had been immunised on this station would contract horse-sickness when subjected to either of the two vira, the following experiments were made:—[…]Our experiments not only demonstrate the fact that the immunity obtained from one virus does not completely protect against either of the other two, but that animals immune against two of the three vira may break down when subjected to the third virus.[…]The fact that polyvalent virus did not protect against all of the constituents, as it should have done, shows that in passing the polyvalent virus through a horse one or more of the vira must have been excluded from the mixture with which the horse was injected.[…]Accordingly, we again decided to increase the polyvalency of the virus by introducing into it, in addition to the strains with which we have inoculated hitherto, such other strains as have broken the immunity, and, in adding to the strain of polyvalent virus the new vira of relapses, we hope to finally arrive at a virus which will give immunity against any strain of the country.[…]The question may perhaps suggest itself whether an immunity of an animal can be increased by the repeated injection of different strains of vira at intervals, and the following table may prove interesting:—[…]

text: The very obvious predominance of epidermal lesions in the gross pathological anatomy of variola and vaccinia, whether spontaneous or experimentally induced, has for many years been interpreted as indicating a peculiar affinity of these vira for skin and not merely for skin-tissue as a whole, but for that portion of it which is derived from epiblast.[…]Immunity to the vira in question was generally held to reside in the skin itself, and it is surprising that the demonstration by Sternberg (1892) of the fact that the serum of vaccinated animals acquired the property of neutralizing the specific virus in vitro so that a mixture of the two failed to take in a fresh animal, did so little to alter general opinion in the direction of postulating a general type of immunity, and that, too, although the presence of these viricidins or neutralizing bodies received ample confirmation from the work of Béclère, Chambon and Menard (1899) and many others.
ref: 1925, Lister Institute of Preventive Medicine, Collected Papers, volume 21, page 35:
text: Neutralization tests, utilizing a hyperimmune horse serum and a hyperimmune rabbit serum, were conducted with the two vira.[…]The technique of preparing virus suspensions, mixing and holding serum-virus inocula, was identical to that employed by Howitt in neutralization tests of poliomyelitis and equine encephalomyelitis vira. / A series of three tests was conducted, using S. D. and Md vira on the same days, with controls in the form of normal serum-virus mixtures and saline-virus mixtures of the same virus dilution as that in the immune serum-virus mixtures.[…]The Md virus disease in the guinea-pigs is of a more acute type than the S. D. virus infection and the vira show certain immunological differences.

text: Table 4 shows the results of these tests, which show convincingly that the vira are related, as could be expected, but certainly not identical.

text: Further virus is found most frequently in the tissues to which it has especial affinity, for ex. in the lymph of vaccine pustules and of the blisters of hoof and mouth disease, in the brain cells in the case of neurotrop vira.

text: In this paper were presented results of isolation of vira from some organs of the dead newborn infants during the epidemy Coxsackie B virosis in Sarajevo in 1985. 12 newborn died. Obduction was done in seven newborn. From the seven obducated, in six were isolated Coxsackie B-3 vira from heart, lungs, brain, liquor, blood, heart blood but the attempts of isolation of the vira from intestine and from pericardial liquor did not succeed.

text: The difference in diabetogenic properties of the D and B variants might, however, be related to the affinity of the vira for beta-cell receptors. Thus, a study has shown that up to six times more EMC-D than EMC-B virus attaches to primary beta cells extracted from male ICR-Swiss mice.

text: > *ducks* :) / Nothing to duck about, cross-platform vira are as yet rare, however complety^([sic]) possible in the newer parsed languages. Vira have come up that target also Netscape.[…]If people simply reviewed their outbound folder prior to sending many of the vira would have been less able to spread like wildfire.

text: Additionally, the question of whether it is the host or the vira/bacteria that exhibit seasonality arises.

text: In accordance with the attached figure, the cocktail according to the present invention is an association of a commercial anti-tumoral medicament, such as doxorubicin (1), whose function is to destroy the hiding-place of the vira (i.e., the lymphocytes) by lowering the count of lymphocytes to zero in the blood by acting as an immunosuppressor, an inhibitor of P-glycoprotein, such as tariquidar (2), whose purpose is to maximize the preceding anti-tumoral compound in the lymphocytes, and an anti-virus of the viricide type, such as N,N-dichloro-2,2-dimethyltaurin (NVC-422) (3), which acts directly on the virus, whose purpose is to eliminate completely the Aids virus in the organism.[…]Cocktail according to claim 1, characterized in that it eliminates completely the HIV virus in the organism by the destroying action of the lymphocytes TCD4+ (the hiding-place of the HIV virus) by the anti-tumoral compound and by the inhibitor of glycoprotein P, exposing the virus later to the direct action of the viricide agent, thereby eliminating completely all the vira in the organism.

text: The vira that were around the Portland metropolitan/US population during my education were measles, mumps, chicken pox and polio.[…]Early childhood had three common vira, measles, mumps and chicken pox, they were called early childhood diseases.[…]As my siblings and myself had no input on what or how my parents deemed the best plan for inoculation/immunization against the vira was going to be, they along with the overall majority of parents CHOSE, not legislated.[…]I knew no one that ever got any of the vira again.
