Treatment With Chemical And Botanical Pesticides In Opposition To Ticks
Anaplasma phagocytophilum is a bacterium of deer that spreads to sheep where it causes tick-borne fever in Europe, leading to abortion by ewes and short-term sterility of rams. This bacterium invades and proliferates in neutrophil cells of the blood. This depletes these antibacterial cells and renders the host prone to opportunistic infections by Staphylococcus aureus bacteria which invade joints and trigger the crippling disease of sheep called tick pyaemia. Anaplasma marginale infects marginal areas of purple blood cells of cattle and causes anaplasmosis wherever boophilid ticks occur as transmitters.

Anaplasma centrale tends to contaminate the central region of pink blood cells, and is sufficiently carefully related to An. marginale to have been used from way back as a live vaccine to guard cattle in opposition to the more virulent An. Sheep and goats undergo disease from infection with Anaplasma ovis which is transmitted similarly to the anaplasmas described above. Ehrlichia ruminantium is transmitted mainly by Amblyomma hebraeum and Am.
When ticks feed, they secrete saliva containing highly effective enzymes and substances with strong pharmacological properties to keep up flow of blood and reduce host immunity. This isn’t due to a practical toxin in the sense that snake poison is useful for the snake. However, the end result could be various types of toxaemia attributable to a wide range of ticks.
