Anaplasmosis is '''not directly contagious''' and most transmission occurs via ticks.

Anaplasmosis is '''not directly contagious''' and most transmission occurs via '''[[Ticks | ticks]]'''.  

 

Infected [[erythrocytes]] are disrupted and release bodies which can invade other erythrocytes. These bodies form vacuoles within the cytoplasmic membranes of the [[erythrocytes | red blood cells]] and then undergo binary fission to form inclusion bodies. This amplifies infection within the host and increases the likelihood of transmission when insects bloodfeed.

 

Other insects can be important vectors depending upon location, such as dipteran flies in the USA.

Cattle that recover become persistent '''carriers''' and although clinical signs do not recrudesce, sequential ricketssial lifecycles are ongoing and therefore reinfection of insect vectors and transmission to other vulnerable animals continues.
