These then develop into '''piroplasma''' within the [[Erythrocytes | erythrocytes]].  

[[Theileria]] species first invade the local [[Lymph Nodes - Anatomy & Physiology|lymph nodes]] of the hosts before disseminating through the lymphoid tissues. Asexual reproduction in the host is followed by sexual reproduction within the [[Ticks | tick]] vector. The [parasite is then transmitted through the salivary glands of the tick into the mammalian host during bloodfeeding.

These piroplasms include the gametes which are infective for ticks and capable of '''sexual reproduction'''.

In endemic areas, '''endemic stability''' is often reached, in which most or all cattle may be infected and be carriers and most ticks are also infected, but young calves gain solid immunity from their immune dams and therefore rarely show clinical disease. This state however takes time to stabilise and will cause significant economic losses in the process.
