Abstract

Ten bovine lymph nodes with granulomatous lesions, resulted positive for R. equi and negative for M. bovis at cultural examination, were subjected to histology and immunhistochemistry by a polyclonal anti-R. equi antibody and a monoclonal anti-VapA antibody to differentiate microscopically the lesions from those observed in tubercular lymphoadenitis. Eight out of ten samples resulted positive when stained by the polyclonal antibody, while no one displayed positivity for VapA. These results show that lesions associated with R. equi are characterized by peculiar features, and that immunostaining for R. equi but not for VapA protein can be considered a useful marker of the infection.
