SLA and leishmaniasis: As in the literature, the data demonstrated here also show high cross-reactivity between sera from dogs with VL and ehrlichiosis, superior to SLA and other recombinant proteins (rP0, rP2b, rHSP70, rHSP83, and rH2A), which limits the performance of rKMP-11 in the diagnosis of dogs clinically suspected or subclinical for leishmaniasis.
