VP2 gene coding region of a vaccinal strain (D78) of infectious bursal disease virus (IBDV) was clonedin a eukaryotic expression vector, pSec Tag2A. The gene was placed downstream of Ig κ chain leadersequence, under the control of human cytomegalovirus (hCMV) immediate early enhancer and promoter. Theconstruct pSec Tag2A-VP2 was transfected in COS-7 cell line and the expression and secretion of...

A 66 year old patient with multiple myeloma and monoclonal cryoglobulinaemia who developed a severe haemolytic anaemia following a cytomegalovirus infection is reported. The presence of a high titre of anti-'i' cold antibody of IgM subclass is demonstrated. Anti-'i' antibody disappeared when complement-fixation antibody titres against cytomegalovirus decreased. Various pathogenetic mechanisms i...

Cytomegalovirus (CMV) is an important pathogen in HIV (Human Immunodeficiency Virus) patients, as it could drive accelerated disease progression leading to increased morbidity and mortality the population. This cross-sectional study analyzed plasma samples from 93 positive participants Rivers State University Teaching Hospital, Port Harcourt, Nigeria, investigate magnitude associated factors of...

An overnight assay, based on staining cytomegalovirus-infected cells with monoclonal antibody to the 72,000-molecular-weight major immediate-early viral protein, was compared with a conventional 14-day plaque assay for quantitation of cell-free stocks of cytomegalovirus laboratory strain AD-169 and 20 other clinical strains. Viral titers were quantitatively similar when determined by either met...

Human cytomegalovirus induces the appearance of immediate early antigens in infected cells 1 h after infection. This provided the basis for the development of a rapid neutralization assay for cytomegalovirus antibody which was able to yield results within a single day. Indirect immunofluorescence to visualize immediate early antigen-positive cells was applied to the rapid determination of cytom...

A fluorescein isothiocyanate-labeled monoclonal cytomegalovirus antibody reagent incorporating Evans blue (Syva/Genetic Systems, Palo Alto, Calif.) was compared to a fluorescein isothiocyanate-labeled polyclonal antibody (Dynatech Diagnostics, Inc., South Windham, Maine) for identification of cytomegalovirus in tissue culture. A total of 191 cultures, 86 positive and 105 negative for cytomegalo...

Indirect immunofluorescence and hemagglutination study of reactivity to human cytomegalovirus immediate early, early, and late antigens revealed that antibody responses to these antigens varies greatly and that hemagglutination is positive when sera contain only antibody to one or both early antigens.
