Detection of Breda virus antigen and antibody in humans and animals by enzyme immunoassay.
نویسندگان
چکیده
Enzyme immunoassays were developed for the detection of Breda virus antibody and antigen. Cattle sera collected in the United Kingdom were found to have a high prevalence of antibody (55%) to Breda virus when examined in a competitive enzyme-linked immunosorbent assay. A low prevalence of antibody was found in pigs (2.2%), and no antibody was found in sheep or goat sera. No antibody to either Breda virus or Berne virus was detected in human sera collected from veterinarians and farm workers. Only 1 of 430 human fecal specimens (0.2%) contained Breda virus antigen detectable by enzyme-linked immunosorbent assay.

Indication of Anti-HBc Antibody Screening and HBV-DNA Detection in Diagnosing Latent Hepatitis B Virus Infection
Background: In spite of available, and sensitive screening assay for detection of hepatitis B virus surface antigen (HBsAg), occasional cases of post-transfusion hepatitis B virus infection are still observed. The aim of the present study was to assess the prevalence of positive anti hepatitis B core (anti-HBc) and presence of HBV-DNA in serum sample of healthy blood donors negative for both HB...

An indirect enzyme–linked immunosorbent assay (ELISA) was developed for screening of antibody to avian infectious bronchitis virus (IBV). Antigen was prepared from whole-purified IBV Massachusetts serotype (BR 801 strain). Optimum dilution with minimum background for antigen concentration, rabbit anti-chicken conjugate and sera in developed ELISA was determined 0.1μg/ml, 1:3000 and 1:100, respe...

Background and Aims: The aim of this study was application of gamma irradiated FMDV antigen for liquid phase blocking sandwich ELISA (B-ELISA) to quantify guinea pig anti FMDV type A87/IRN antibody. Methods: FMDV type A87/IRN was propagated to a titer of 107.5/ml TCID50 and then irradiated by gamma irradiator. The irradiated 146 S antigen was purified by sucrose gradient centrifugation after in...

Introduction: Cryptosporidiosis is prevalent world wide, causing a variety of problems ranging from acute, self-limiting diarrhea to fatal cases in immunocompromised persons, particulary those with acquired immunodeficiency (AIDS). Diagnosis of Cryptosporidium is made by identification of oocysts in stool specimens. The detection is most commonly made by the acid-fast staining method followed b...
متن کاملProduction of Monoclonal Antibody against Prokaryotically Expressed G1 Protein of Bovine Ephemeral Fever Virus
Epitope-G1 of bovine ephemeral fever virus (BEFV) G glycoprotein has been genetically and antigenically conserved among various isolates of BEFV and only reacts with anti-BEFV neutralising antibodies. Therefore, it is a candidate antigen for development of the enzyme linked immunosorbent assay (ELISA) for serological identification bovine ephemeral fever (BEF)-infected animals. The aim of this ...
