Thymidine kinase-deficient herpes simplex virus type 2 genital infection in guinea pigs.

Expression of the Herpes Simplex Virus Type 2 Glycoprotein D in Baculovirus Expression System and Evaluation of Its Immunogenicity in Guinea Pigs

Background: Herpes simplex virus type 2 (HSV-2) is highly prevalent and major cause of genital herpes in humans. The life-long nature of infection and the increasing prevalence of genital herpes imply that vaccination is the best strategy for controlling the spread of infection and limiting HSV disease. HSV glycoprotein D (gD) is one of the most important viral immunogen which has an essential ...

PCR detection of thymidine kinase gen of latent herpes simplex Virus type 1 in mice trigeminal ganglia

  Herpes simplex virus type 1 establishes a latent infection in the peripheral nervous system following primary infection. During latent infection, virus genome exhibit limited transcription, with the HSV LATs consistently detected in latency infected ganaglia. Following ocular infection viral latency develops in the trigeminal ganglia. In this study PCR has been used for detection of HSV-1 nuc...

Pathogenesis of acyclovir-resistant herpes simplex type 2 isolates in animal models of genital herpes: models for antiviral evaluations.

Our understanding of the pathogenesis of acyclovir (ACV)-resistant herpes simplex virus (HSV) is limited, especially with regard to reactivation and recurrent disease. To further explore the pathogenesis of ACV-resistant HSV-2 viruses, we used the guinea pig model of genital HSV-2 infection to evaluate several ACV-resistant isolates of both thymidine kinase (Tk)-altered and Tk-deficient phenoty...

Restriction Enzyme Analysis of Thymidine Kinase Gene in Four Iranian Isolates of Herpes Simplex Virus Type 1

DNA immunization against experimental genital herpes simplex virus infection.

A nucleic acid vaccine, expressing the gene encoding herpes simplex virus (HSV) type 2 glycoprotein D (gD2) under control of the cytomegalovirus immediate-early gene promoter, was used to immunize guinea pigs against genital HSV-2 infection. The vaccine elicited humoral immune responses comparable to those seen after HSV-2 infection. Immunized animals exhibited protection from primary genital H...
