Plain-English summary

A group of dogs being treated with doxycycline for Ehrlichia canis, a tick-borne illness, were found to still carry the bacteria even after 14 days of treatment. This means that despite receiving medication, these dogs could still pass the infection to ticks. As a result, it's important for pet owners to be aware that treated dogs can still be a source of infection for ticks, which could pose a risk to other pets and humans.

Abstract

Doxycycline generally alleviates clinical monocytic ehrlichiosis, but its efficacy in the control of monocytotropic ehrlichial pathogens requires further investigation. In this study, Ehrlichia canis was detected in dogs treated with doxycycline for 14 days and in ticks fed on these dogs, suggesting that treated dogs can remain reservoirs for E. canis.
