In an effort to obtain the flexibility and ease of performance of a rapid, serological test for detection of cytomegalovirus antibody, the indirect hemagglutination (IHA) technique was investigated by using a microserological system. Antigens were prepared from tissue cultures of infected human fibroblasts. The specificity of the cytomegalovirus antibody response detected by the IHA test correl...

A human osteogenic sarcoma cell culture is useful in the immunofluorescence serological test for detecting human cytomegalovirus antibody. These sarcoma cells are chronically infected with human cytomegalovirus and provide a constant number of immunofluorescence-positive cells.

The local secretory immune mechanism in infants with cytomegalovirus infection was studied by a measurement of neutralizing antibody in saliva. Neutralizing antibodies were determined by the microculture plaque assay in 65 saliva specimens including 54 samples from cytomegalovirus-infected subjects and 11 from seronegative controls. In addition, cytomegalovirus isolation from saliva or urine or...

A general-purpose reagent capable of reacting with immunoglobulin G in a modified enzyme-linked immunosorbent assay technique was prepared by using protein A coupled with horseradish peroxidase. The reagent detected low levels (0.003 to 1.0 microgram/ml) of human immunoglobulin G and was also applied in an enzyme-linked immunosorbent assay for titration of antibody to human cytomegalovirus. The...

BACKGROUND Elevated levels of antibodies to Cytomegalovirus (CMV) have been associated with cognitive impairment, but the quantitative relationship between CMV antibody levels and domains of cognitive functioning in younger adults has not been established. METHODS We measured IgG class antibodies to Cytomegalovirus in 521 individuals, mean age 32.8 years. Participants were selected for the ab...

Herpesviruses are main sculptors of natural killer (NK) cell repertoires. While the ?-herpesvirus human cytomegalovirus (CMV) drives accumulation adaptive NKG2C-positive NK cells, ?-herpesvirus Epstein–Barr virus (EBV) expands early differentiated NKG2A-positive cells. cells support immunity by antibody-dependent cellular cytotoxicity, seem to preferentially target lytic EBV replicating B The i...

BACKGROUND Chemotherapeutic treatment for patients with symptomatic coronary artery disease to reduce cardiovascular events may be initiated in response to elevated antibody titers against Chlamydia pneumoniae or cytomegalovirus. How antibody titers are associated with the endovascular presence of these microorganisms is still unclear. METHODS AND RESULTS Antibody titers against C pneumoniae ...

INTRODUCTION The occurrence of cytomegalovirus colitis is well known in immunosuppressed patients, such as neoplastic patients following chemotherapy, although its exact etiology remains unclear. CASE PRESENTATION We present a case of cytomegalovirus colitis occurring in a 77-year-old man with vomiting and diarrhea 2 weeks after initial systemic chemotherapy consisting of 5-fluorouracil, leuc...
