A Breed Aside Cats - Ticks are trouble! We all know that they spread the bacteria that lead to Lyme condition, but an additional tick-borne condition that is steadily growing is ehrlichiosis. When restricted to western Texas, Oklahoma and Missouri, the incidence of ehrlichiosis is expected to rise in these places, as effectively as in southern California and the southeastern United States, according to the Companion Animal Parasite Council.
Dogs with ehrlichiosis can build an acute infection that begins with fever, appetite loss and lethargy. Two to four weeks soon after encountering the bite of an infected tick, a subclinical infection can set in, causing thrombocytopenia. That $5 word implies that the canine doesn’t have sufficient platelets in his blood. When that occurs, he can encounter bleeding into physique tissues (known as petechiae) and bruising. His blood may clot more gradually than standard soon after an injury. Bone marrow suppression can end result from chronic Ehrlichia spp. (the "spp." refers to all species of this sort of bacteria) infection. It can seem months to years soon after a tick bite.
A Breed Aside Cats - Cats with the condition may display similar indications. Other indications seen in cats and canines include weight loss, joint discomfort, vomiting and diarrhea.
How It’s Spread
Three tick species are recognized to spread the organism that leads to ehrlichiosis. The brown canine tick (Rhipicephalus sanguineus), located throughout the United States, is the primary culprit, but the American canine tick (Dermacentor variabilis) and the lone star tick (Amblyomma americanum) can also transmit the bacteria that lead to condition. You may think lone star ticks would be restricted to the Lone Star State (Texas, of program), but they are located up from the southeastern U.S. and Texas by way of the Mid-Atlantic Seaboard all the way to New England. American canine ticks reside east of the Rockies, mainly in places this kind of as grassy fields, walkways and trails. They can survive for two or more years without a host.
Dogs (and cats) turn out to be infected with Ehrlichia spp. when infected ticks feed on them, injecting the bacteria into their blood by deeply burying their mouthparts into the skin. Nasty!
A Breed Aside Cats - It can get as minor as three to 6 hrs for ticks to transmit the bacterial invaders. When the bacteria enter the blood cells, they thrive, multiply and spread throughout the physique. The condition is diagnosed primarily based on a history of tick publicity, presence of indications, a platelet count and a positive blood test end result for the bacteria that lead to the condition: Ehrlichia canis (the primary lead to in canines), Ehrlichia ewingii (seen in canines and humans) and Ehrlichia chaffeensis (the primary lead to in humans). Ehrlichiosis isn’t always straightforward to diagnose, because it can get time for antibodies to build, but response to treatment method with antibiotics can be a clue that your veterinarian has located the lead to of your canine’s indications.
