Decrease in antimicrobial susceptibility of Bordetella bronchiseptica caused by antigenic modulation and phase variation.

abstract：:The antiviral activity of a new series of thymidine analogs was determined against vaccinia virus (VV), cowpox virus (CV), herpes simplex virus, and varicella-zoster virus. Several compounds were identified that had good activity against each of the viruses, including a set of novel 5-substituted deoxyuridine analogs....
