A survey was conducted to determine the prevalence of T. evansi in domestic animals in Rayalaseema region of Andhra Pradesh during the year 2009-10. A total of 1166 blood and sera samples from cattle, buffaloes and sheep were collected and screened by Wet blood film examination and Indirect ELISA. Overall, 1.54 and 24.52 per cent animals were found positive for T. evansi by Wet blood film (WBF)...
Dengue virus (DENV) is the world most prevalent mosquito-transmitted virus. The incidence of dengue infection has been increasing and most of the infected people are asymptomatic or have non specific febrile illness. Laboratory test is essential to confirm dengue infection in epidemiological studies. We developed an indirect ELISA test based on monoclonal immunoglobulin against all four DENV se...
We studied the use of the precursor to the M structural protein (prM) found only on the surface of mature dengue virus as a target protein to detect dengue virus infection. Recombinant D2-16681 prM-M protein was constructed and tested for immunogenicity with dengue and Japanese encephalitis patient sera by Western blot analysis and indirect ELISA. The sensitivity and specificity of indirect ELI...
Peptides deduced from the central hydrophobic region (residues 158-189) of the G protein of bovine and ovine respiratory syncytial virus (RSV) and of human RSV subtypes A and B were synthesized. These peptides were used to develop ELISAs to measure specifically antibodies against these types and subtypes of RSV. We have evaluated the bovine RSV-G peptide in both an indirect ELISA and in a block...
The aims of this study were to evaluate the performance and agreement of various commercial and in-house Neospora caninum antibody assays used in dairy cattle in North America, and to investigate reproducibility of two assays performed in different laboratories. From 1998 to 2005, three enzyme linked immunosorbent assays (ELISAs, a competitive ELISA-VMRD Inc., an indirect ELISA-Biovet Inc., and...
Clostridium perfringens type A enterotoxin was specifically detected and readily quantified by indirect and four-layer sandwich enzyme-linked immunosorbent assays (ELISAs). With the indirect ELISA, enterotoxin was detected in quantities of as low as 2.5 ng (25 ng/ml). When the more sensitive sandwich ELISA procedures was used, 100 pg (1 ng/ml) of enterotoxin was detected. The sandwich ELISA pro...
Abstract Equine infectious anemia is a worldwide distributed disease that affects the Equide family. Commercial effective vaccine not available, for reason control of depends on diagnostic tools. To improve efficiency program in Cuba, LABIOFAM Group, developed an indirect enzyme-linked immunosorbent assay (ELISA), ELISA kit, to complement system currently uses agar gel immunodiffusion (AGID) ki...
Toxoplasma gondii infections in heart transplant recipients were monitored by indirect enzyme-linked immunosorbent assay for immunoglobulin G (ELISA-IgG), indirect ELISA-IgM in serum IgM fractions, antibody capture ELISA-IgM, IgM-immunosorbent agglutination assay (ISAGA), and IgM immunoblotting. Basic immunosuppression consisted of cyclosporine and low-dose steroids. Before transplantation, 26 ...
Neospora caninum, an Apicomplexan parasite that can causes abortion, is responsible for considerable economic and reproductive losses in livestock. The purpose of the present study was to determine whether recombinant NcSRS2 is a suitable indirect ELISA antigen for determining specific immune response to N. caninum in sheep. A total of 441 serum samples were subjected to IFAT and rNcSRS2 based-...
This paper reports a negative-pressure driven microfluidic chip, which is capable of rapidly detecting bladder cancer biomarker, APOA1, with aid of magnetic beads-based Enzyme-linked immunosorbent assays (ELISA). Fluid can be handled through vacuum force and normally-closed valve. Comparing the experimental results between integrated chip and 96 well plate, the former requires less time (4 hr t...
