Diversity, Host Attachment Preferences and Role of Tick Rhipicephalus microplus in the Transmission of Bartonella spp. and Rickettsia spp. in Cattle From Southern Benin

open access: yesVeterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Ticks infesting cattle in Southern Benin were investigated for diversity, attachment preferences and zoonotic bacteria. Among 2210 ticks collected from 540 cattle, Rhipicephalus microplus predominated (79.6%). Ticks mainly attached to ears, axillae and trunk. PCR detection revealed Bartonella spp. and Rickettsia spp., highlighting veterinary and public
