treatment methods” using infected blood followed by
treatment of reacting animals with tetracyclines.
Strategic tick control (Low intensity dipping): The
strategic tick control allows animals to be exposed to
ticks but not to a level that the ticks become a nuisance.
This allows animals to get regular re-infection with
heartwater parasites to maintain immunity.
Sick animals should be treated as soon as possible
after the clinical signs are observed. Any of the short
or long acting formulations of injectable tetracyclines
are recommended for treatment of heartwater.
Farmers are advised to make sure that the treatment
instructions are read carefully for the correct dosage
and treatment method.
The implementation of these preventative
measures should be customized to suit the inherent
environmental conditions and livestock production
system of an area/farm or village. It is therefore
important to consult a veterinarian/animal health
technician who is acquainted with the local disease
conditions to assist with appropriate control strategy.
