Correction: Evaluation of Monoclonal Antibody-Based Sandwich Direct ELISA (MSD-ELISA) for Antigen Detection of Foot-and-Mouth Disease Virus Using Clinical Samples

Table 1 appears incorrectly due to errors in the typesetting process. The correct version of Table 1 can be viewed below.

^*MS: MSD-ELISA for multi-serotypes; SS: MSD-ELISA for single serotypes (O, A, Asia1); IS: Indirect sandwich-ELISA for each serotype (O, A, Asia1); rPCR: real-time RT-PCR.

^†The OD results (average sample OD-average buffer OD) of the MS, SS and IS ELISAs were as +++, >1.0; ++, 0.51.0; +, 0.10.5; and −, < 0.1.

^‡The results-related plaque-forming unit of rPCR were as +++,<104; ++, 102-103; +, 100-102; and −, >100.

^§The pigs inoculated with virus were euthanized.

^‖‖Squares mean the day the obvious vesicular appeared except for the inoculated site.
