Anaplasmas
Lifecycle
Any stage of the tick’s lifecycle can become infected with Anaplasma organisms. After development within the tick, the final infective stage is within the salivary glands and is injected into the bloodstream of the host when the parasite bloodfeeds. Male ticks are more mobile and longer lived therefore may play a bigger role.
See Tick Disease Transmission for more information on ticks as disease vectors.
