HCMV antiviral drug resistance can be detected by phenotypic or by genotypic drug resistance testing. Phenotypic resistance testing involves cultivation of the virus in cell culture and testing its susceptibility using different antiviral drug concentrations in order to determine EC50 values.
Cidofovir (CDV) does not require initial phosphorylation for its antiviral action. Further phosphorylation to the triphosphate form of GCV and CDV is performed by cellular kinases. The nucleoside-triphosphate-analogues compete with the cellular nucleotide triphosphates at the viral polymerase pUL54 and are incorporated into the viral DNA.
The most studied is Human cytomegalovirus (HCMV), which is also known as Human betaherpesvirus 5 (HHV-5). Other primate CMV species include Chimpanzee cytomegalovirus (CCMV) that infects chimpanzees and orangutans , and Simian cytomegalovirus (SCCMV) and Rhesus cytomegalovirus (RhCMV) that infect macaques ; CCMV is known as both Panine beta ...
In the past nucleic acid tests have mainly been used as a secondary test to confirm positive serological results. [3] However, as they become cheaper and more automated, they are increasingly becoming the primary tool for diagnostics and can also be use for monitoring of treatment of viral infected individuals t.
Nine herpesvirus types are known to primarily infect humans, [7] at least five of which are extremely widespread among most human populations, and which cause common diseases: herpes simplex 1 and 2 (HSV-1 and HSV-2, also known as HHV-1 and HHV-2; both of which can cause orolabial and genital herpes), varicella zoster (or HHV-3; the cause of ...
A Southern California business owner convinced victims to invest in his companies, claiming he could detect Covid-19 based on video, and then made lavish purchases, prosecutors said.
The hearing came a day after Mangione was arrested in Altoona. Police searched Mangione and found a fake New Jersey driver's license and a "semi-automatic pistol" with a silencer, both made by a ...
Congenital HCMV infection occurs when the mother has a primary infection (or reactivation) during pregnancy. Due to the lower seroprevalence of HCMV in industrialized countries and higher socioeconomic groups, congenital infections are actually less common in poorer communities, where more women of child-bearing age are already seropositive.
