The development and evaluation of an enzyme-linked immunosorbent assay for the detection of Mycobacterium bovis.

Abstract

A double antibody sandwich layer enzyme-linked immunosorbent assay (ELISA) was used to detect Mycobacterium bovis. The ELISA detected M. bovis is pure culture at concentrations of 1 x 10(5) colony-forming units (CFU) ml-1 and greater, compared to a minimum detection level of 1 x 10(6) CFU ml-1 for isolation techniques. Neither technique detected M. bovis at 1 x 10(4) CFU ml-1. The ELISA did not cross-react with common mycobacterial contaminants such as Mycobacterium avium intracellulare-scrofulaceum complex serotypes 18 and 42, M. terrae, M. fortuitum, M. flavescens and with Escherichia coli or Rhodococcus equi. Further work is needed to evaluate this assay in detecting M. bovis in tissues and the environment.
