Two dogs from Quebec were diagnosed with granulocytic anaplasmosis. They both displayed fever, lethargy, and anorexia. Other clinical signs included vomiting, uveitis, polyarthritis, hepatomegaly, and splenomegaly. Thrombocytopenia, anemia, and lymphopenia were identified in both cases. Cytoplasmic inclusions were observed within neutrophils, and infection was confirmed by polymerase chain reaction in both dogs.

Human granulocytic anaplasmosis (HGA) is transmitted by the black-legged tick and presents with fever, thrombocytopenia, leukocytopenia, and elevated transaminases. If left untreated, HGA can progress to hemophagocytic lymphohistiocytosis (HLH), which can be fatal. Here, we discuss a case of a woman diagnosed with anaplasmosis who was treated promptly.

Background/aims: Sera from patients from a single medical institution in New York State with human granulocytic anaplasmosis established by a positive polymerase chain reaction test (PCR) for Anaplasma phagocytophilum were used to assess the performance of serologic testing. All cases were also confirmed by culture in order to eliminate any false positive PCR samples.
Methods: A nested PCR was performed targeting the heat shock operon of A.

Ticks are vectors of public health concern because the pathogens they transmit can cause detrimental diseases in humans. Lyme disease, tick-borne relapsing fever, human granulocytic anaplasmosis, Rocky Mountain spotted fever, tick-borne encephalitis, Crimean-Congo hemorrhagic fever, and babesiosis are some of the most common diseases caused by the pathogens transmitted by ticks. The overlap between human activities and tick habitats is growing, contributing to an increase in tick-borne disease cases.
