Scanning electron micrograph of a male Rhipicephalus sanguineus (Acari: Ixodidae) of tropical lineage. This tick is the main vector of canine erlichiosis in the neotropics and is a potential vector of the deadly Rickettsia rickettsii. This ectoparasite belongs to a close related group of ticks known as the R. sanguineus complex. This species complex, widely distributed across the world, affects mainly dogs. Micrograph taken by Luis E. Paternina at the Advanced Microscopy Laboratory (Laboratorio de Microscopía Avanzada) from the Universidad Nacional de Colombia, Medellín.
