The measurement of the avidity of cytomegalovirus (CMV) immunoglobulin G (IgG) antibodies has been shown by several investigators to be useful in identifying and excluding primary CMV infections in pregnant women. In this work, we examined the diagnostic utility of reflex testing of CMV IgM-positive specimens from pregnant women by using a CMV IgG avidity assay. The utility of this approach was...

This paper describes an improved method for the in vitro detection of antibodies specifically directed against human cytomegalovirus (CMV)-induced membrane antigens present on the surface of CMV-infected fibroblasts (CMV-MA). Viable cells were found to be essential for specific visualization of CMV-MA staining. The addition of divalent cations (2.6 mM Ca2+ and 2.2 mM Mg2+) and glucose (180 mM) ...

Objective—To study the association between anti-ganglioside antibody responses and Guillan-Barré syndrome (GBS) after a recent cytomegalovirus (CMV) infection. Methods—Enzyme linked immunosorbant assay (ELISA) was undertaken on serum samples from 14 patients with GBS with recent cytomegalovirus (CMV) infection (CMV+GBS) and 12 without (CMVGBS), 17 patients with other neurological diseases (OND)...

Cytomegalovirus (CMV) is the most important pathogen affecting the outcome of renal transplantation. Reinfection of CMV can occur in CMV-seropositive donors and CMV seropositive recipients (D+/R+) settings because the protection against CMV conferred by preexisting immunity is limited due to its strain-dependent immune responses. To analyze the influence of CMV reinfection in renal transplantat...

The presence of Herpes Simplex Virus-type 2 (HSV type 2), Cytomegalovirus(CMV) and Adenovirus lgG antibodies was determined in sera from a total 144 patients with hematologic solid organ malignancies. HSV type-2 were detected using the EIA method antibody levels 34(48.5 %) ofthe 56(75.6 malignancies of90 (62.5 %). Anti-CMV IgG same serum samples complement fixation test. Residual anti-CMV 43(61...

This study describes the results of testing 92 serum samples, including 10 umbilical cord serum samples, from 38 cytomegalovirus (CMV)-infected neonates for CMV-specific immunoglobulins E (IgE) and M by antibody-capture enzyme-linked immunosorbent assays with enzyme-labeled CMV antigen. All infants excreted CMV in the urine. It was demonstrated that the CMV IgE test was more sensitive than the ...

To investigate whether antecedent cytomegalovirus (CMV) infections in patients with Guillain-Barre syndrome are associated with the presence of specific antiganglioside antibodies, acute phase serum samples from 130 patients with Guillain-Barre syndrome and 200 controls were tested. Anti-GM2 IgM antibodies were found more often in patients with Guillain-Barre syndrome with CMV infection (22%) t...

BACKGROUND & OBJECTIVES We undertook this study to determine the infectious aetiology of congenital cataract based on the presence of IgM antibodies to TORCHES [(Toxoplasma gondii (T. gondii), Rubella virus (RV), Cytomegalovirus (CMV), Herpes simplex virus (HSV) and Syphilis (caused by Treponema pallidum)] in the serum samples of congenital cataract patients. METHODS Serum samples collected f...

Two monoclonal antibodies which react specifically with cells infected by cytomegalovirus (CMV) are described. One antibody, 6-E3, reacts with a 72,000-dalton protein that appears early in infection and remains localized in the cell nucleus. The other antibody, 6-C5, reacts with an 80,000-dalton protein that appears late in infection and remains localized in cytoplasmic inclusion bodies. Both m...
