Abstract
Tick-borne infectious diseases constitute an emerging problem in Veterinary Medicine. The study was undertaken to find out the ultrasonographic changes of liver and spleen in 101 positive cases of tick borne intracellular haemoparasitic diseases in dogs. Abdominal survey of ultrasonography revealed hypo echogenicity of liver, gall bladder distension, splenomegaly, hepato-splenomegaly and ascites in various tick born intracellular diseases viz. ehrlichiosis, babesiosis, anaplasmosis, hepatozoonosis and in mixed infection. Correlating these USG finding with other laboratory examination will be very much useful to spot the diseases condition and organ involvement in tick born intracellular diseases of dog.
