An enzyme-linked immunosorbent assay (ELISA) was developed for the detection of antibodies to influenza A/Hong Kong/1/68, influenza A/Victoria/3/75, influenza B/Hong Kong/5/72, and parainfluenza type 1 viruses. Development and standardization of the method indicated that an acetone-ethyl alcohol mixture was a suitable fixative for the preparation of the solid-phase coupled antigen. The addition...

A solid-phase competition ELISA has been developed to measure antibodies to foot-and-mouth disease (FMD) virus and has been validated using an extensive range of sera from cattle. The assay uses polyclonal antisera and inactivated purified 146S antigens of FMD virus and was compared with the liquid-phase blocking ELISA and the virus neutralisation test on a range of serum sets. When examining t...

Five serological tests for the diagnosis of visceral leishmaniasis (VL) were compared: a direct agglutination test (DAT) based on freeze-dried antigen (DAT-fd); a locally produced DAT (DAT-LPC); an IgG ELISA against rK39 (ELISA-rK39); an IgG ELISA for Leishmania chagasi (ELISA-L. chagasi); and an IgG IFAT against L. chagasi. Serum samples from 88 patients with VL, 20 non-infected individuals an...

GİRİŞ ve AMAÇ: İnsan İmmun Yetmezlik Virüsü (HIV) ölümcül seyredebilen AIDS (Acquried-immunodeficiency syndrome) olarak tanımlanan hastalığa neden olmaktadır. Bu çalışmada anti HIV/1-2 testi reaktif saptanan olguların doğrulama sonuçlarının incelenmesi, hatalı pozitif ELISA önüne geçebilmek için uygun eşik değerin belirlenmesi amaçlanmıştır. YÖNTEM GEREÇLER: Çalışmamızda XXX Hastanesi Laboratuv...

The Recombigen HIV-1 Latex Agglutination (LA) Test was recently licensed by the U.S. Food and Drug Administration for use as a rapid screening assay for human immunodeficiency virus type 1 (HIV-1) antibodies. However, its performance in various settings and in different populations has not been firmly established. Consequently, we evaluated the test in the Cleveland Clinic Retrovirus Laboratory...
