Clinical isolates of HSV and VZV with reduced susceptibility to acyclovir have been recovered from immunocompromised patients, especially with advanced HIV infection. While most of the acyclovir-resistant mutants isolated thus far from such patients have been found to be TK-deficient mutants, other mutants involving the viral TK gene TK partial and TK altered and DNA polymerase have been isolated. TK-negative mutants may cause severe disease in infants and immunocompromised adults.
