Heterogeneity of the polyribocytidylic acid tract in aphthovirus changes in the size of polyribocytidylic acid of viruses recovered from persistently infected cattle

, : Heterogeneity of the polyribocytidylic acid tract in aphthovirus changes in the size of polyribocytidylic acid of viruses recovered from persistently infected cattle. Virology 162(1): 58-64

A sample of aphthovirus type C3 strain Resende carrying two polyribocytidylic acid [poly(C)] tracts was cloned in tissue culture. One clone with a poly(C)-rich tract of about 145 nucleotides long (clone 3B) and another with poly(C)-rich tract of about 230 nucleotides long (clone 12) and a mixture of both were injected intralingually into three steers. Samples from all three animals were recovered during the acute phase of the disease, from the blood and from the feet, and at various days after inoculation from the oesophageal-pharyngeal (OP) fluids. Analysis of the viral RNA of the positive samples by means of RNase T1 maps on one- and two-dimensional gels showed (1) changes in the electrophoretic mobility of the poly(C)-rich tracts of viruses recovered from the OP fluids at various times after infection; (2) selection of virus populations with poly(C)-rich tracts of increased size; (3) later on, changes in the patterns of oligonucleotides of persistent viruses. These variations may lead to the production of new strains with altered biological properties that may contribute to the maintenance and spread of these viruses in the field.

This self-renewal vs. differentiation spermatogonial fate de...
