Anaplasmosis

It
is a blood born disease due to protozoa. This disease is transmitted
through ticks which act as mechanical vectors. Buffalo, cattle,
sheep and goat are susceptible. There is marked anemia. Anaplasma is
causative organism. This disease is present throughout the world in
all tropical, subtropical, and other climatic regions. Crossbreds
and foreign breeds like Fresian are more prone to this disease but
local animals are resistant.

60 %

Culicoid mosquitos and mites. Transmission is also through
contamination of instruments, syringes and blood transfusion.
