HCMV replicates within infected endothelial cells [23] at a slow rate, taking about five days in cell culture. [24] It also infects fibroblasts, which requires expression of only a trimeric viral receptor complex, rather than the full pentameric complex that is required for infection of endothelial and epithelial cells. [25]
The 11 species in this genus include human betaherpesvirus 5 (HCMV, human cytomegalovirus, HHV-5), which is the species that infects humans. Diseases associated with HHV-5 include mononucleosis and pneumonia , [ 4 ] [ 5 ] and congenital CMV in infants can lead to deafness and ambulatory problems.
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.
Ganciclovir (9-[(1,3-dihydroxy-2-propoxy)methyl]guanine) is a potent inhibitor of viruses of the herpes family, including cytomegalovirus (CMV), that are pathogenic for humans and animals. The primary mechanism of ganciclovir action against CMV is inhibition of the replication of viral DNA by ganciclovir-5'-triphosphate (ganciclovir-TP).
Certain viruses, such as human cytomegalovirus (HCMV) and hepatitis C (HCV), have adapted to suppress the function of MAVS in the antiviral innate immune response, aiding in viral replication. [7] [11] HCMV impairs MAVS through the viral mitochondria-localized inhibitor of apoptosis protein (vMIA), thus reducing the pro-inflammatory cytokine ...
The plaque reduction neutralization test is used to quantify the titer of neutralizing antibody for a virus. [1] [2] The serum sample or solution of antibody to be tested is diluted and mixed with a viral suspension. This is incubated to allow the antibody to react with the virus. This is poured over a confluent monolayer of host cells.
Congenital cytomegalovirus (cCMV) is cytomegalovirus (CMV) infection in a newborn baby. [1] Most have no symptoms. [1] Some affected babies are small. [1] Other signs and symptoms include a rash, jaundice, hepatomegaly, retinitis, and seizures. [1] [2] It may lead to loss of hearing or vision, developmental disability, or a small head. [1]
Cytomegalovirus retinitis, also known as CMV retinitis, is an inflammation of the retina of the eye that can lead to blindness. [1] Caused by human cytomegalovirus , it occurs predominantly in people whose immune system has been compromised, including 15-40% of those with AIDS.
