Covid-19 Vaccination and Reactivation of Varicella Zoster Virus
Introduction: After COVID-19 pandemic in 2020 that mostly affects upper respiratory tract, the scientists investigated an effective vaccine against the virus. As the vaccination of general population started some patients were visited with varicella zoster virus activation following the COVID vaccine.
متن کاملAcyclic guanosine analogs as substrates for varicella-zoster virus thymidine kinase.
This study was performed to obtain information on the enzymatic background to the antiviral activity of acyclic guanosine analogs. Five acyclic guanosine analogs, the (R)- and (S)-enantiomers of 9-(3,4-dihydroxybutyl)guanine, 9-(4-hydroxybutyl)guanine, 9-[(2-hydroxyethoxy)methyl]guanine, and 9-[[2-hydroxy-1-(hydroxymethyl)ethoxy]methyl]guanine, were compared in enzyme kinetic experiments using ...
متن کاملSeroprevalence of Varicella-Zoster Virus in Children from Shiraz-Iran
Background: Varicella–zoster virus (VZV) causes herpes zoster and varicella (Chicken-pox), usually a mild disease which is diagnosed clinically with few complications. However, in neonates and healthy adults it can have a severe presentation. Herpes zoster results from VZV reactivation later in life. Objective: To determine the seroprevalence of VZV in elementary school children aged 6-10 years...
متن کاملImmunochemical characterization of pyrimidine kinase induced by varicella-zoster virus.
Thymidine kinase (TK) induced by varicella-zoster virus (VZV) was precipitated with ammonium sulphate and purified by Sephadex G-150, QAE-Sephadex and Blue Sepharose column chromatographies. The purified TK fraction also contained deoxycytidine kinase (dCK) activity and a 35000 mol. wt. (35K) polypeptide as a major component. The TK and dCK activities were both neutralized by anti-VZV serum. An...
متن کاملAnalysis of the thymidine kinase genes from acyclovir-resistant mutants of varicella-zoster virus isolated from patients with AIDS.
Patients with AIDS often experience recurrent infections with varicella-zoster virus (VZV) requiring repeated or prolonged treatment with acyclovir (ACV), which may lead to the development of ACV resistance. The ACV resistance of isolates recovered from such patients is associated with diminished VZV thymidine kinase (TK) function. We determined the nucleotide sequences of the TK genes of 12 AC...
