Causes
Anaplasmosis is caused by bacteriaBacteria are microscopic, single-celled organisms that exist in almost every environment on Earth. Some types of bacteria are beneficial or even essential to life, while others can cause disease. of the genus Anaplasma, with Anaplasma phagocytophilum and Anaplasma platys being the most common pathogens in dogs. These bacteriaBacteria are microscopic, single-celled organisms that exist in almost every environment on Earth. Some types of bacteria are beneficial or even essential to life, while others can cause disease. are intracellular microorganisms that infect and multiply in white blood cells or plateletsPlatelets, also called thrombocytes, are cells in the blood that play a crucial role in blood coagulation. They help stop Bleeding by forming clots that seal injuries in blood vessels..
Anaplasma phagocytophilum is mainly transmitted through the bite of Ixodes ticks (such as the common wood tick). These ticks are also responsible for the transmission of Lyme borreliosis. Anaplasma platys, on the other hand, is transmitted by the brown dog tick (Rhipicephalus sanguineus) and mainly affects the plateletsPlatelets, also called thrombocytes, are cells in the blood that play a crucial role in blood coagulation. They help stop Bleeding by forming clots that seal injuries in blood vessels., leading to temporary thrombocytopeniaThrombocytopenia is a condition in which the number of platelets in the blood is lower than normal, increasing the risk of mild to severe Bleeding..
The infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease. occurs when an infected tick bites a dog and the bacteriaBacteria are microscopic, single-celled organisms that exist in almost every environment on Earth.
