The proportion of acyclovir (ACV)-resistant herpes simplex virus (HSV) isolates in clinical specimens and laboratory isolates was determined. Schaffner, Proc. ELF-EMF exposure did not affect the growth and viability of BCBL-1 cells, either stimulated or not with TPA. Nongenital lesions at the time of acquisition of genital herpes were observed in 25%, 9%, and 2% of patients with primary HSV-1, primary HSV-2, and nonprimary HSV-2, respectively. These methods are inefficient when the frequency of recombinants in the pool of viruses is low. Levin and his colleagues have demonstrated that waning VZV-specific CMI in elderly persons can be stimulated by varicella vaccine to levels typical of those observed in younger persons, in whom the incidence and severity of HZ are much reduced. Epstein Barr genome was found in 40% of cases.

DNA of CBV, EBV and herpes virus type 6 in the children amounted for 2, 13 9 cases respectively. A relative deficiency in CpG and an excess of TpG and CpA dinucleotides is a diagnostic feature of higher eukaryotic DNA sequences that have been subjected to methylation of cytosine residues in CpG doublets with the resulting increase in mutations to give TpG (and thereby its complement, CpA). The RMF of two independent UNG- viruses showed no significant difference from the baseline RMF in limited passage; however, following successive passage, the data suggested that UNG activity serves as an antimutator. These results have implications for the natural history of HSV and the development of antiviral therapies.
