Also known as: Febre da carraça
A erliquiose é uma doença transmitida por carraças causada por bactérias Ehrlichia que infetam os glóbulos brancos. Nos cães, Ehrlichia canis, transmitida pela carraça castanha do cão, causa febre aguda e tendência hemorrágica que pode progredir para uma fase crónica com supressão da medula óssea. Algumas espécies de Ehrlichia também infetam pessoas através de picadas de carraça, o que a torna uma preocupação zoonótica.
Ehrlichiosis is a rickettsial disease caused by Ehrlichia species, most notably Ehrlichia canis in dogs. It is transmitted by ticks and has zoonotic relatives that infect people.
Infection follows the bite of an infected tick, chiefly the brown dog tick. The bacteria invade white blood cells and disseminate through the body.
Acute disease causes fever, lethargy, weight loss, and bleeding tendencies with low platelets; chronic disease can cause severe bone-marrow suppression and pancytopenia.
Diagnosis uses antibody tests, PCR, and blood smears showing morulae, alongside complete blood counts revealing thrombocytopenia.
Doxycycline is highly effective, especially in the acute phase; transfusions and supportive care may be needed in severe chronic cases.
Use year-round tick control, perform regular tick checks, and manage the environment to reduce brown dog tick infestations.
