Abstract:

Background: Diarrhea in newborn small ruminants continues to be the cause of significant financial loss in sheep and goat farms worldwide. Commercial immunochromatographic (IC) assays have been designed and evaluated to be used for the diagnosis of diarrhea in cattle; however, there are no trials to use rapid tests in small ruminants.

Aim: This study was carried out in Kuwait to evaluate the performance of the rapid immunochromatography test (BoviD-4, BioNote, Inc, Korea) for diagnostics of , rotavirus A (RVA), bovine coronavirus (BCoV), and K99 ( K99) in fecal samples of sheep and goats.

Methods: A total of 85 samples were examined using BoviD-4, and the results were compared with that of polymerase chain reaction for , RVA, and BCoV, whereas for K99 it was by isolation and identification as reference tests.

Results: The kappa test agreement results between the BoviD-4 and reference tests were 0.870 (perfect), 0.783 (substantial), 0.728 (substantial), and 0.281 (fair) for the detection of K99, , RVA, and BCoV, respectively. The sensitivity of BoviD-4 kit was 91.2%, 80.0%, 90.0%, and 37.5% and the specificity was 88.2%, 96.0%, 96.4%, and 92.2% for , RVA, K99, and BCoV, respectively.

Conclusion: The Bovid-4 kit can be used as a rapid pen-side test for spp., K99, and RVA in the field. Nonetheless, care must be taken while interpreting the BCoV results of the kit.
