In this study, the role of cholesterol in the envelope of human herpesvirus 6 (HHV-6) was examined by using methyl-beta-cyclodextrin (MbetaCD) depletion. When cholesterol was removed from HHV-6 virions with MbetaCD, infectivity was abolished, but it could be rescued by the addition of exogenous cholesterol. HHV-6 binding was affected slightly by MbetaCD(More)
Uracil-DNA glycosylase encoded in many species functions as a DNA repair enzyme that removes uracil residues from DNA. To investigate the potential function of uracil-DNA glycosylase encoded by human herpes-virus 6 (HHV-6), we sequenced a DNA clone (pSTY09), identified an open reading frame of 765 bp and compared the putative amino acid sequence with other(More)
Ixodid ticks were collected from medium-sized to large mammals in Ehime Prefecture, Shikoku, Japan. Ten species of ticks (Amblyomma testudinarium, Dermacentor taiwanensis, Haemaphysalis flava, H. formosensis, H. hystricis, H. longicornis, H. megaspinosa, Ixodes nipponensis, I. ovatus, and I. tanuki) were collected from a total of 29 mammals comprising 11(More)
