Transmission of <i>Leishmania infantum</i> by <i>Rhipicephalus sanguineus</i> (Acari: Ixodidae) in Dogs.

Abstract

<i>L. infantum</i>-positive <i>R. sanguineus</i> ticks were unable to transfer <i>L. infantum</i> from infected dogs to healthy ones. The detection of <i>L. infantum</i> DNA in ticks collected from naturally infected dogs by semi-nested PCR does not prove their vectorial competence.
