A new method for attaching antigens to latex by an avidin-biotin technique is described. The procedure permits control of the amount of antigen attached to the latex and eliminates the need for highly purified antigens and destructive bridging chemicals. The avidin-biotin latex agglutination assay is a simple, rapid test well suited to detection of viral antibody. The sensitivity and specificit...

Mononucleosis and mononucleosis-like illnesses comprise a significant proportion of pediatric and adolescent infectious illnesses. By far, the most common cause of these illnesses is Epstein-Barr virus, which causes mononucleosis, and a distant second is cytomegalovirus, which is the most common cause of mononucleosis-like illnesses. This case provides an interesting juxtaposition of laboratory...

guillain barre syndrome (gbs) is an inflammatory, usually demyelinating, polyneuropathy; clinically characterized by acute onset of symmetric progressive muscle weakness with loss of myotatic reflexes. thirty five patients with gbs, defined clinically according to the criteria of asbury and cornblath, were recruited from three hospital affiliated to tehran university of medical sciences.as a co...

The complete amino acid and nucleotide sequences of the variable regions of the heavy and light polypeptide chains of a human neutralizing IgGl anti-cytomegalovirus (CMV) antibody reveal a striking homology to IgM rheumatoid factors (RFs) of the Wa idiotypic family. The anti-CMV antibody and Wa RFs have in common VKIIIb, JKl, and VHIa gene segments but use different DH and JH gene segments. The...

We compared the pp65 antigen detection by an in house method (immunoperoxidase assay) and by a commercial kit (immunofluorescence assay) available for cytomegalovirus infection diagnosis in immunocompromised patients. Sixty-four blood samples were analyzed in duplicate for both techniques. Eight-six percent of the samples had concordant qualitative results. The discordant results occurred more ...

Background: Human Cytomegalovirus (CMV) is one of the most significant pathogens infecting immunosuppressed individuals. CMV is known to be a significant cause of morbidity and mortality following blood transfusion in immunocompromised individuals. The immunosuppressed population for whom CMV free blood products are requested is increasing due to advances in medical care. The most effective way...

A fluorescein-conjugated murine monoclonal antibody (MAb) reactive with cytomegalovirus (CMV) was evaluated for the detection of CMV in centrifugation culture. Of 188 specimens, 90 were positive for CMV in centrifugation culture. The fluorescein-conjugated MAb detected CMV in 86 of 90 (95%) specimens at 16 h postinoculation, and 88 of 90 (98%) were positive at 36 h. The fluorescein-conjugated M...

\s=b\Serum samples from 184 Infants and children whose blood was drawn during a clinic visit were tested for antibody to Chlamydia trachomatis, Epstein-Barr virus, and cytomegalovirus. Lifetime illness history was obtained from clinic records. Fifteen percent had anti\p=n-\Ctrachomatis IgM antibody. Anti\p=n-\Ctrachomatis IgM without IgG was significantly associated with upper respiratory tract...
