Development and application of an indirect ELISA for the serological detection of bovine viral diarrhea virus infection based on the protein E2 antigen.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundBovine viral diarrhea virus (BVDV) causes continuous economic losses to the livestock industry. Monitoring antibodies with enzyme-linked immunosorbent assay (ELISA) is a valuable tool to ensure the purification of BVDV in cattle. However, currently available ELISA kits based on the whole BVDV virion are both costly and time-consuming. The E2 protein has good immunogenicity, induces the secretion of neutralizing antibodies and is an essential immunogen for serological detection. METHODS AND
resultsWe developed a novel recombinant E2 protein-based indirect ELISA (rE2-iELISA) and conducted a serological survey for BVDV antibodies in 2021-2022 in Beijing, China. The results showed that E2 protein was successfully expressed with high immunogenicity and the optimal rE2-iELISA displayed high sensitivity, reproducibility and specificity. Clinical testing of 566 serum specimens indicated that 318 BVDV positive samples and 194 BVDV negative samples were tested by rE2-iELISA and the IDEXX BVDV ELISA-Ab kit, with a positive coincidence rate of 93.3%, a negative coincidence rate of 86.3%, and an overall coincidence rate of 90.5%.
conclusionThis study established an rE2-iELISA method, which is a highly sensitive, specific and robust ELISA-test validated to detect anti-BVDV antibodies. These findings indicate that the newly developed rE2-iELISA method has the potential to be used as a rapid, reliable and cost-effective screening tool for BVDV infection and provides technical support for the evaluation of vaccine efficacy in cattle herds in the future.
