In this study 253 serum samples from cattle showing respiratory disorders were tested by confirmatory Western Immunoblotting test (IBT), complement fixation (CFT) and competitive enzyme linked immunosorbent assay (c-ELISA). Two (0.8%) out of found to be positive two doubtful CFT while 7 (2.8%) as 25 (9.9%) them c-ELISA. On the other hand, a core profile antigenic bands needed identified at 110,...

ABSTRACT: The fluorescence polarization assay (FPA), two variants (V) of the indirect enzyme-linked immunosorbent (I-ELISA) and competitive (C-ELISA) were evaluated in buffaloes to detect antibodies against Brucella spp. V1 I-ELISA identifies them through monoclonal (M23) anti-bovine IgG (I-ELISAM23) V2 ProteinA / G (I-ELISA-A/G). Serum samples 862 (Bubalus bubalis) from Northeast Argentina (NE...

A competitive enzyme-linked immunosorbent assay (C-ELISA) using a baculovirus-expressed recombinant nucleocapsid protein antigen (rNDV-N) and an rNDV-N-specific monoclonal antibody (5B3) was developed for the detection of Newcastle disease virus (NDV) antibodies, and its diagnostic performance was evaluated. The specificity and sensitivity of the C-ELISA was found to be 98.4 and 98.9%, respecti...

In this paper, we present a provably secure redactable signature scheme allowing to independently redact structure and content. We identify the problems when structure is not separated from content, resulting in an attack on the scheme proposed at VLDB ’08 by Kundu and Bertino. The attack allows for changing the semantic meaning of a given tree. We introduce a rigid security model, including co...

Advances in diagnostic assays for parasitic diseases include the use of monoclonal antibodies (MAbs) in antigen capture and competitive inhibition enzyme-linked immunosorbent assays (C-ELISA). Antigen capture ELISAs for Anaplasma marginale and Cryptosporidium parvum provide direct detection of these parasites during clinical disease, and the C-ELISA format has been adapted for detection of anti...

Paratuberculosis (PTB) is a major disease problem worldwide, and causes major economic losses in the dairy industry. Although PTB has been reported in Korea, no studies have been conducted to determine its prevalence and no program has been developed to control the disease. In this study, the sera of beef (n = 1,056) and dairy cattle (n = 1,105) from all provinces in Korea were tested to determ...

A monoclonal antibody (MAb)-based antigen capture enzyme-linked immunosorbent assay (ELISA) was compared with the routine culture methodology for the detection of Campylobacter fetus subspecies from bovine and ovine field samples inoculated into Clark's transport enrichment medium (TEM). The work was a collaboration between two different diagnostic laboratories, one in Canada and the other in E...

Thermostabilizing effect of heavy water (D2O) or deuterium oxide has been demonstrated previously on several enzymes and vaccines like oral poliovirus vaccine and influenza virus vaccine. In view of the above observations, effect of heavy water on in situ thermostabilization of recombinant p26 protein on enzyme-linked immunosorbent assay (ELISA) for serodiagnosis of equine infectious anemia vir...
