Foci of cells infected with human cytomegalovirus were noted to stain more intensely than uninfected cells with neutral red, and this provided the basis for development of a plaque assay and plaque reduction neutralization test for cytomegalovirus. Plaques demonstrable by neutral red staining could be counted at 8 days after infection; thus, results could be obtained earlier than for plaque ass...

OBJECTIVE To study the passive immunization with human monoclonal antibodies as for prophylaxis of human cytomegalovirus (HCMV) infection. METHODS Fab monoclonal antibodies to HCMV were recovered by repertoire cloning of mRNA from a HCMV infected individual. Antigen binding specificity, CDR sequence of V(H) and V(L) and neutralizing activity on HCMV AD169 stain were analyzed in vitro. The lig...

The nucleoside analog 2'-nor-2'-deoxyguanosine (2'NDG) effectively inhibits the replication of several laboratory and clinical isolates of human cytomegalovirus. These isolates included viruses obtained from congenitally infected infants and patients suffering from acquired immune deficiency syndrome. The dose of 2'NDG that inhibited cytomegalovirus plaque formation ranged from 0.1 to 1.6 micro...

Background Beta-thalassemia patients receive blood products from blood transfusion centers repeatedly. Blood transfusion can transmit Cytomegalovirus (CMV) and Toxoplasma gondii. The aim of this study was serological evaluation of these two infectious agents in thalassemia patients. Materials and Methods In a cross-sectional study, the enzymelinked immunosorbent assay (ELISA) testing was pe...

  Background and Objective: Sinusitis is one of the most common hygienic problems and a large part of the budget has been allocated to its diagnosis and treatment yearly. In this study, the presence of cytomegalovirus in sinuses of patients, undergone operation for treatment, with or without sinusitis, was studied. Materials and Methods: This study was an applied and case-co...

We conducted a cross-sectional study of beta-herpesviruses in febrile pediatric oncology patients (n = 30), with a reference group of febrile pediatric solid-organ transplant recipients (n = 9). One (3.3%) of 30 cancer patients and 3 (33%) of 9 organ recipients were PCR positive for cytomegalovirus. Four (13%) of 30 cancer patients and 3 (33%) of 9 transplant recipients had human herpesvirus 6B...

SUMMARY Human cytomegalovirus (HCMV) is a common, medically relevant human herpesvirus. The tegument layer of herpesvirus virions lies between the genome-containing capsids and the viral envelope. Proteins within the tegument layer of herpesviruses are released into the cell upon entry when the viral envelope fuses with the cell membrane. These proteins are fully formed and active and control v...

Human cytomegalovirus (HCMV) is a ubiquitous virus whose sole host is humans. Since HCMV can contagion from person to person through numerous ways, vast populations of humans are infected. HCMV infections can potentially have a range from asymptomatic infection in immuno-competent hosts to life-threatening diseases in organ recipients and patients with AIDS. The present article reviews the occu...
