Rapid detection directly from patient serum samples of human cytomegalovirus UL97 mutations conferring ganciclovir resistance.
Ganciclovir-resistant cytomegalovirus can cause disease and death in transplant recipients. We describe here a rapid PCR- and sequencing-based assay for ganciclovir resistance that can be performed in 1 to 2 working days directly from patient specimens, without the need for amplification of the virus by cell culture. An evaluation of 120 sequential samples submitted for clinical testing reveale...
متن کاملIncidence of ganciclovir resistance in CMV-positive renal transplant recipients and its association with UL97 gene mutations
Human cytomegalovirus (CMV) remains the most common infection affecting organ transplant recipients. Despite advances in the prophylaxis and acute treatment of CMV, it remains an important pathogen affecting the short- and long-term clinical outcome of solid organ transplant recipient. The emergence of CMV resistance in a patient reduces the clinical efficacy of antiviral therapy, complicates t...

متن کاملCytomegalovirus UL97 kinase mutations that confer maribavir resistance.
The cytomegalovirus (CMV) UL97 kinase inhibitor maribavir (MBV) is undergoing clinical antiviral trials. Two clinical CMV isolates serially passaged in cell culture under MBV showed >20-fold increases in MBV resistance after the development of the UL97 mutation V353A in one of the isolates and of T409M in the other. Marker transfer studies confirmed that the V353A and T409M mutations conferred ...
متن کاملCytomegalovirus UL97 kinase catalytic domain mutations that confer multidrug resistance.
Human cytomegalovirus UL97 kinase mutations that commonly confer ganciclovir resistance cluster in different parts of the gene than those conferring resistance to maribavir, an experimental UL97 kinase inhibitor. The drug resistance, growth, and autophosphorylation phenotypes of several unusual UL97 mutations in the kinase catalytic domain were characterized. Mutations V466G and P521L, describe...
