is a small rickettsia that can cause ehrlichiosis in dogs. It is
usually transmitted through the bite of an infected tick (Rhipicephalus
sanguineus) or other arthropod.
was first reported in 1978 in dogs from Florida; Infectious Canine
Cyclic Thrombocytopenia (ICCT) was the name given to the disease
caused by this strain. Since then, ICCT has been reported in many
areas of the United States and in other regions of the world.
In most previous
reports, ICCT was considered a benign disease without obvious clinical
signs. Therefore, A. platys
was not considered a very pathogenic organism or an important
disease-causing agent. However, other investigators have reported more
severe clinical signs, similar in severity to those associated with
E. canis infections.
Dogs infected with these rickettsiae will develop cyclic parasitemia
and cyclic thrombocytopenia at 7- to 14-day intervals.
Due to cyclic
parasitemia, detection of
Anaplasma in blood smears can be difficult. The pathogen

can be detected via ELISA or IFA testing. Such serology testing can
identify dogs with prior exposure but is not useful for detecting
re-infection or carrier status. Examination of blood smears can detect
the pathogen but the sensitivity of this technique is very low.
Molecular detection by real time PCR, which is very specific and
sensitive, is useful to quickly identify this pathogen and confirm
dogs’ re-infection or carrier status.
