Antibody titres were measured in patients with clinical syphilis, and the effect of treatment on the results of the Treponema pallidum immune adherence (TPIA) test is reported. In the Treponema pallidum haemagglutination (TPHA) test little change in antibody titre occurred after treatment while in the fluorescent treponemal antibody-absorbed (FTA-ABS) test only a slight decrease occurred. The d...

A case of fulminant viral hepatitis type B in the late stage of pregnancy was successfully treated with glucagon-insulin therapy, corticosteroids and other drugs. A 26-year-old female (housewife and primipara) suddenly developed severe hepatic dysfunction and disturbance of consciousness at the 36th week of pregnancy. Sequential blood examinations revealed early response to HBs antibody and del...

Background: Dengue is an acute viral infection has emerged as a notable public health problem. Rapid immunochromatographic test and IgM/IgG ELISA been the mainstay of diagnosis. Combination NS1 antigen detection along with antibody increases diagnostic rates. Thrombocytopenia begins during febrile phase. Therefore, we tried to evaluate association platelet counts against (NS1 IgM/IgG) IgM in de...

OBJECTIVE: To determine the antibody levels (IgM and IgG), using ELISA in suspected patients of COVID-19. STUDY DESIGN: Descriptive cross-sectional study. Place & Duration Study: Real Time PCR Diagnostic Research Laboratory, Peshawar, Khyber Pakhtunkhwa, Pakistan, from May to July 2020. METHODOLOGY: A total 94 blood specimens were collected COVID-19 patients. The (IgG IgM) determined, a IgG IgM...

These last months, dozens of SARS-CoV-2 serological tests have become available with varying performances. A major effort was completed to compare 17 in April 2020 Switzerland. In a preliminary phase, we compared IgG, IgM, IgA and pan Ig including ELISA, LFA, CLIA ECLIA on panel 182 sera, comprising 113 sera from hospitalized patients positive RT-PCR, 69 sampled before 1st November 2019, expect...

Human heterophilic hemagglutinin to rabbit erythrocytes was quantitatively determined by the hemagglutination test and enzyme linked immunosorbent assay (ELISA) using rabbit erythrocyte pentaglycosyl ceramide (CPH), Gal (a 1-3) Gal (fl 1-4) GlcNAc (fl 1-3) Gal (fl 1-4) Glc-Cer as the antigen. The antibody levels in sera from 74 Hanganutziu-Deicher (H-D) antibody-positive patients were significa...

Three hundred and twenty four serum samples, collected from different areas of Punjab, NWFP and Azad Kashmir, were screened for Toxo IgG and IgM antibody titres utilizing the Enzyme linked immunosorbent assay (ELISA). Of the total 149 (46%) samples were positive for IgG antibody. Seven (2.1%) showed titre greater than 130. Ninety sera (27.7%) were positive for IgM antibody, twenty six (8%) had ...

Blood samples were collected from 100 pediatric AIDS patients for the detection of CMV in pp65-bearing leukocytes (PBLs) by immunoperoxidase staining (IP) and PCR. IgM antibody assay was performed to determine the correlation of antigen and antibody. IP and PCR can be used as methods for the early detection of CMV (prior to the presence of IgM antibody). The sensitivity and specificity of IP we...

Streptococcus pneumoniae is a microorganism that frequently causes serious infections in children, the elderly, and immunocompromised patients. We studied whether the specific intracellular adhesion molecule-grabbing nonintegrin R1 (Sign-R1) receptor, involved in the uptake of capsular polysaccharides (caps-PS) by antigen-presenting cells, is necessary for the antibody response to pneumococcal ...
